Replace <linux/mod_devicetable.h> by more specific <linux/device-id/*.h> (c files)
Replace the #include of <linux/mod_devicetable.h> by the more specific <linux/device-id/*.h> where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

Patchsets in this merge:
- The 2 patch series "selftests/mm: clean up build output and verbosity"
from Li Wang removes some noise from the MM selftests build out.
- The 3 patch series "mm: Free contiguous order-0 pages efficiently"
from Ryan Roberts speeds up the freeing of a batch of 0-order pages by
first scanning them for coalescing opportunities. This is applicable to
vfree() and to the releasing of frozen pages.
- The 11 patch series "mm/damon: introduce DAMOS failed region quota
charge ratio" from SeongJae Park addresses a DAMOS usability issue: The
DAMOS quota often exhausts prematurely because it charges for all memory
attempted, causing slow and inconsistent performance when actions fail
on unreclaimable memory.
To fix this, a new feature lets users set a smaller, flexible quota
charge ratio (via a numerator and denominator) for failed regions.
Since failed actions cause less overhead, reducing their quota cost
ensures more predictable and efficient DAMOS processing
- The 8 patch series "selftests/cgroup: improve zswap tests robustness
and support large page sizes" from Li Wang fixes various spurious
failures and improves the overall robustness of the cgroup zswap
selftests.
- The 3 patch series "fix MAP_DROPPABLE not supported errno" from
Anthony Yznaga fixes an issue in the mlock selftests on arm32.
- The 2 patch series "mm: huge_memory: clean up defrag sysfs with
shared" from Breno Leitao does some maintenance work in the huge_memory
code.
- The 3 patch series "treewide: fixup gfp_t printks" from Brendan
Jackman uses the special vprintf() gfp_t conversion in various places.
- The 6 patch series "mm: Fix vmemmap optimization accounting and
initialization" from Muchun Song fixes several bugs in the vmemmap
optimization, mainly around incorrect page accounting and memmap
initialization in the DAX and memory hotplug paths. It also fixes
pageblock migratetype initialization and struct page initialization for
ZONE_DEVICE compound pages.
- The 4 patch series "mm/damon: repost non-hotfix reviewed patches in
damon/next tree" from is a sprinkle of unrelated minor bugfixes for
DAMON.
- The 3 patch series "mm: remove page_mapped()" from David Hildenbrand
remove this function from the tree, replacing it with folio_mapped().
- The 10 patch series "mm/damon: let DAMON be paused and resumed" from
SeongJae Park permits DAMON to be paused and resumed without losing its
current state.
- The 3 patch series "kasan: hw_tags: Disable tagging for stack and
page-tables" from Muhammad Usama Anjum simplifies and speeds up kasan by
removing its ineffective tagging of stacks and page tables.
- The 7 patch series "mm/damon/reclaim,lru_sort: monitor all system rams
by default" from SeongJae Park simplifies deployment on diverse hardware
like NUMA systems by updating DAMON_RECLAIM and DAMON_LRU_SORT to
automatically monitor the physical address range covering all System RAM
areas by default, replacing the overly restrictive behavior that only
targeted the single largest memory block to save on negligible overhead.
- The 2 patch series "mm/damon/sysfs: document filters/ directory as
deprecated" from SeongJae Park updates some DAMON docs.
- The 8 patch series "mm: use spinlock guards for zone lock" from Dmitry
Ilvokhin switches zone->lock handling over to using the guard()
mechanisms.
- The 2 patch series "mm/filemap: tighten mmap_miss hit accounting" from
fujunjie fixes a flaw where the mmap_miss counter over-credited page
cache hits during fault-arounds and page-fault retries. This results in
significant reduction of redundant synchronous mmap readahead I/O,
drastically cutting down execution time and gigabytes read for sparse
random or strided memory access workloads.
- The 2 patch series "selftests/cgroup: Fix false positive failures in
test_percpu_basic" from Li Wang fixes a couple of false-positives in the
cgroup kmem selftests.
- The 2 patch series "mm/damon/reclaim: support monitoring intervals
auto-tuning" from SeongJae Park adds a new parameter to DAMON permitting
DAMON_RECLAIM to automatically tune DAMON's sampling and aggregation
intervals.
- The 2 patch series "mm/damon/stat: add kdamond_pid parameter" from
SeongJae Park chnges DAMON_STAT to provide the pid of its kdamond.
- The 2 patch series "mm/kmemleak: dedupe verbose scan output" from
Breno Leitao removes large amounts of duplicated backtraces from the
verbose-mode kmemleak output.
- The 8 patch series "mm: remove CONFIG_HAVE_BOOTMEM_INFO_NODE (Part 1)"
from David Hildenbrand reduces our use of CONFIG_HAVE_BOOTMEM_INFO_NODE,
with a view to removing it entirely in a later series.
- The 2 patch series "mm/damon: validate min_region_size to be power of
2" from Liew Rui Yan prevents users from passing a non-power-of-2 value
of `addr_unit', as this later results in undesirable behavior.
- The 2 patch series "mm: document read_pages and simplify usage" from
Frederick Mayle does as claimed.
- The 3 patch series "tools/mm/page-types: Fix misc bugs" from Ye Liu
fixes three issues in tools/mm/page-types.c.
- The 4 patch series "mm: misc cleanups from __GFP_UNMAPPED series" from
Brendan Jackman implements several cleanups in the page allocator and
related code.
- The 12 patch series "mm, swap: swap table phase IV: unify allocation"
from Kairui Song unifies the allocation and charging of anon and shmem
swap in folios, provides better synchronization, consolidates the
metadata management, hence dropping the static array and map, and
improves performance.
- The 28 patch series "mm/damon: introduce data attributes monitoring"
from SeongJae Park extends DAMON for monitoring general data attributes
other than accesses.
- The 5 patch series "mm/vmalloc: free unused pages on vrealloc()
shrink" from Shivam Kalra implements the TODO in vrealloc() to unmap and
free unused pages when shrinking across a page boundary.
- The 3 patch series "mm/damon: documentation and comment fixes" from
niecheng does as advertised.
- The 3 patch series "remove mmap_action success, error hooks" from
Lorenzo Stoakes eliminates custom hooks from mmap_action by removing the
problematic success_hook which allowed drivers to improperly access
uninitialized VMAs. It replaces the error_hook with a simple error-code
field and updates the memory char driver accordingly.
- The 14 patch series "mm/damon: minor improvements for code readability
and tests" from SeongJae Park implements minor improvements in code
readability and tests for DAMON.
- The 2 patch series "mm/damon: fix macro arguments and clarify quota
goals doc" from Maksym Shcherba does those things.
- The 2 patch series "userfaultfd: merge fs/userfaultfd.c into
mm/userfaultfd.c" from Mike Rapoport performs that code movement.
- The 15 patch series "mm/mglru: improve reclaim loop and dirty folio"
from Kairui Song and others cleans up and slightly improves MGLRU's
reclaim loop and dirty writeback handling. Large performance
improvements are measured.
- The 3 patch series "use vma locks for proc/pid/{smaps|numa_maps}
reads" from Suren Baghdasaryan uses per-vma locks when reading
/proc/pid/smaps and /proc/pid/numa_maps similar to reduce contention on
central mmap_lock.
- The 2 patch series "refactors thpsize_shmem_enabled_store() and
thpsize_shmem_enabled_show()" from Ran Xiaokai provides some cleanup
work in the THP code.
- The 2 patch series "selftests/memfd: fix compilation warnings" from
Konstantin Khorenko fixes a few build glitches in the memfd selftest
code.
- The 4 patch series "memcg: shrink obj_stock_pcp and cache multiple
objcgs" from Shakeel Butt resolves a 68% performance regression caused
by NUMA-node cache thrashing around struct obj_stock_pcp by shrinking
its existing fields and expanding it into a multi-slot array that caches
up to five obj_cgroup pointers per CPU, allowing per-node variants of
the same memcg to coexist within a single 64-byte cache line.
- The 2 patch series "zram: writeback fixes" from Sergey Senozhatsky
addresses a couple of unrelated zram writeback issues.
- The 9 patch series "mm: switch THP shrinker to list_lru" from Johannes
Weiner resolves NUMA-awareness issues and streamlines callsite
interaction by refactoring and extending the list_lru API to completely
replace the complex, open-coded deferred split queue for Transparent
Huge Pages (THPs).
- The 2 patch series "mm: improve large folio readahead for exec memory"
from Usama Arif improves large-folio readahead on systems like 64K-page
arm64 by preventing the mmap_miss check from permanently disabling
target-oriented VM_EXEC readahead, and by generalizing the
force_thp_readahead gate to support mappings with any usefully large
maximum folio order under the cache cap.
- The 6 patch series "userfaultfd/pagemap: pre-existing fixes" from
Kiryl Shutsemau fixes a bunch of minor issues in the
userfaultfd/pagemap, all of which were flagged by Sashiko review of
proposed new material.
- The 5 patch series "mm/sparse-vmemmap: Provide generic
vmemmap_set_pmd() and vmemmap_check_pmd()" from Muchun Song provides
generic versions of these two functions so the four arch-specific
implementations can be removed.
- The 2 patch series "mm/swap, PM: hibernate: fix swapoff race in
uswsusp by pinning swap device" from Youngjun Park addresses a
uswsusp-vs-swapoff race and reduces the swap device reference
taking/releasing frequency.
- The 2 patch series "mm/hmm: A fix and a selftest" from Dev Jain does
as claimed.

Networking changes for 7.2.
Core & protocols
----------------
- Work on removing rtnl_lock protection throughout the stack continues.
In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even tho
user space wants a dump of all netdevs, most of the time, the OOO
programming model results in repeating the dump for each netdev.
Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on retransmit
timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 > 40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).
- Improve link state reporting for upper netdevs (e.g. macvlan) over
tunnel devices (again, mostly for EVPN deployments).
- Support binding GENEVE tunnels to a local address.
- Speed up UDP tunnel destruction (remove one synchronize_rcu()).
- Support exponential field encoding in multicast (IGMPv3 and MLDv2).
- Support attaching PSP crypto offload to containers (veth, netkit).
- Add a new IPSec Netlink message XFRM_MSG_MIGRATE_STATE that allows
migrating individual IPsec SAs independently of their policies.
The existing XFRM_MSG_MIGRATE is tightly coupled to policy+SA
migration, lacks SPI for unique SA identification, and cannot express
reqid changes or migrate Transport mode selectors. The new interface
identifies the SA via SPI and mark, supports reqid changes, address
family changes, encap removal, and uses an atomic create+install
flow under x->lock to prevent SN/IV reuse during AEAD SA migration.
- Implement GRO/GSO support for PPPoE.
- Convert sockopt callbacks in a number of protocols to iov_iter.
Cross-tree stuff
----------------
- Remove support for Crypto TFM cloning (unblocked after the TCP Auth
Option rework). This feature regressed performance for all crypto API
users, since it changed crypto transformation objects into reference-
-counted objects.
- Add FCrypt-PCBC implementation to rxrpc and remove it from the global
crypto API as obsolete and insecure.
Wireless
--------
- Major rework of station bandwidth handling, fixing issues with lower
capability than AP.
- Cleanups for EMLSR spec issues (drafts differed).
- More Neighbor Awareness Networking (Wi-Fi Aware) work (multicast,
schedule improvements, multi-station etc.)
- Some Ultra High Reliability (UHR) / IEEE 802.11bn (D1.4) work
(e.g. non-primary channel access, UHR DBE support).
- Fine Timing Measurement ranging (i.e. distance measurement) APIs.
Netfilter
---------
- Use per-rule hash initval in nf_conncount. This avoids unnecessary
lock contention with short keys (e.g. conntrack zones) in different
namespaces.
- Various safety improvements, both in packet parsing and object
lifetimes. Notably add refcounts to conntrack timeout policy.
Deletions
---------
- Remove TLS + sockmap integration. TLS wants to pin user pages
to avoid a copy, and sockmap wants to write to the input stream.
More work on this integration is clearly needed, and we can't find
any users (original author admitted that they never deployed it).
- Remove support for TLS offload with TCP Offload Engine (the far
more common opportunistic offload is retained). The locking looks
unfixable (driver sleeps under TCP spin locks) and people from
the vendor that added this are AWOL.
- Remove more ATM code, trying to leave behind only what PPPoATM needs,
AAL5 and br2684 with permanent circuits.
- Remove AppleTalk. Let it join hamradio in our out of tree protocol
graveyard, I mean, repository.
- Disable 32-bit x_tables compatibility (32bit binaries on 64bit kernel)
interface in user namespaces. To be deleted completely, soon.
- Remove 5/10 MHz support from cfg80211/mac80211.

Pull networking updates from Jakub Kicinski:
"Core & protocols:
- Work on removing rtnl_lock protection throughout the stack
continues. In this chapter:
- don't use rtnl_lock for IPv6 multicast routing configuration
- don't take rtnl_lock in ethtool for modern drivers
- prepare Qdisc dump callbacks for rtnl_lock removal
- Support dumping just ifindex + name of all interfaces, under RCU.
It's a common operation for Netlink CLI tools (when translating
names to ifindexes) and previously required full rtnl_lock.
- Support dumping qdiscs and page pools for a specific netdev. Even
tho user space wants a dump of all netdevs, most of the time, the
OOO programming model results in repeating the dump for each
netdev. Which, in absence of a cache, leads to a O(n^2) behavior.
- Flush nexthops once on multi-nexthop removal (e.g. when device goes
down), another O(n^2) -> O(n) improvement.
- Rehash locally generated traffic to a different nexthop on
retransmit timeout.
- Honor oif when choosing nexthop for locally generated IPv6 traffic.
- Convert TCP Auth Option to crypto library, and drop non-RFC algos.
- Increase subflow limits in MPTCP to 64 and endpoint limit to 256.
- Support MPTCP signaling of IPv6 address + port (ADD_ADDR). We need
to selectively skip reporting of the standard TCP Timestamp option,
because they won't fit into the header space together (12 + 30 >
40).
- Support using bridge neighbor suppression, Duplicate Address
Detection, Gratuitous ARP and unsolicited NA forwarding - in EVPN
deployments, e.g. VXLAN fabrics (IPv4 and IPv6).

appletalk: move the protocol out of tree
AppleTalk has been removed in MacOS X 10.6 (Snow Leopard), in 2009, according to Wikipedia. We recently got a burst of AI generated fixes to this protocol which nobody is reviewing. Let AppleTalk follow AX.25 and hamradio out of the Linux tree. We we will maintain the code at: github.com/linux-netdev/mod-orphan for anyone interested in playing with it. Retain the uAPI for now. No strong reason, simply because I suspect keeping it will be less controversial.

Interrupt core code changes:
- Rework of /proc/interrupt handling:
/proc/interrupts was subject to micro optimizations for a long time,
but most of the low hanging fruit was left on the table. This rework
addresses the major time consuming issues:
- Printing a long series of zeros one by one via a format string
instead of counting subsequent zeros and emitting a string
constant.
- Simplify and cache the conditions whether interrupts should be printed
- Use a proper iteration over the interrupt descriptor xarray
instead of walking and testing one by one.
- Provide helper functions for the architecture code to emit the
architecture specific counters
- Convert the counter structure in x86 to an array, which
simplifies the output and add mechanisms to suppress unused
architecture interrupts, which just occupy space for
nothing. Adopt the new core mechanisms.
This adjusts the gdb scripts related to interrupt counter statitics
to work with the new mechanisms.
- Prevent a string overflow in the /proc/irq/$N/ directory name
creation code.

architecture interrupts, which just occupy space for nothing.
Adopt the new core mechanisms.
This adjusts the gdb scripts related to interrupt counter statistics
to work with the new mechanisms.
- Prevent a string overflow in the /proc/irq/$N/ directory name
creation code.

crypto: pcbc - Remove support for PCBC mode
The only user of PCBC mode (Propagating Cipher Block Chaining mode) was net/rxrpc/rxkad.c, which now uses local code instead. While PCBC was an interesting cryptographic experiment, it has largely been relegated to the history books and academic exercises. It is non-parallelizable (i.e., very slow) and doesn't actually achieve the integrity properties it was apparently intended to achieve. Remove support for it from the crypto API.

crypto: fcrypt - Remove support for FCrypt block cipher
Remove the insecure FCrypt block cipher from the crypto API. Its only user was net/rxrpc/, but now net/rxrpc/ implements it locally. The crypto API implementation is no longer needed. For some additional context: FCrypt was designed in 1988 and is essentially a weakened version of DES. It has the same 56-bit key size as DES, which is easily brute forced. Moreover, it's cryptographically weak and doesn't even provide the intended 56-bit security level. Its author considers it to be a mistake, as well (https://lists.openafs.org/pipermail/openafs-devel/2000-December/005320.html). But fortunately this 1980s-era homebrew block cipher was never adopted outside of net/rxrpc/. So its code can just be kept there.

uaccess: unify inline vs outline copy_{from,to}_user() selection
The kernel allows arches to select between inline and outline
implementations of the copy_{from,to}_user() by defining individual
INLINE_COPY_FROM_USER and INLINE_COPY_TO_USER, correspondingly. However,
all arches enable or disable them always together.
Without the real use-case for one helper being inlined while the other
outlined, having independent controls is excessive and error prone.
Switch the codebase to the single unified INLINE_COPY_USER control.

sh: use folio_mapped() instead of page_mapped() in sh4_flush_cache_page()
Patch series "mm: remove page_mapped()". While preparing my slides for an LSF/MM talk, I realized that I did not yet remove page_mapped(). So let's do that. In the BPF arena code it's unclear which memdesc we would want to allocate in the future: certainly something with a refcount, but likely none with a mapcount. So let's just rely on the page refcount instead to decide whether we want to try zapping the page from user page tables. This patch (of 3): We already have the folio in our hands, so let's just use folio_mapped().

genirq/proc: Increase default interrupt number precision to four
Quite some architectures have four character wide acronyms for architecture specific interrupts like IPI, NMI, etc. The default precision of printing the Linux device interrupt numbers is three, which causes quite some code to play games with adding or omitting space after the acronym and the colon in order to keep the per CPU numbers properly aligned. Increase the default number precision to four in the core code and get rid of the space games all over the place. At the same time align all architecture specific descriptor texts left so that they show up in the same column as the interrupt chip names, which makes the output more uniform accross architectures. Fix up the GDB script to this new scheme as well. Signed-off-by: Thomas Gleixner <tglx@kernel.org> Link: https://patch.msgid.link/20260517194931.839482411@kernel.org |

ring-buffer: Flush and stop persistent ring buffer on panic
On real hardware, panic and machine reboot may not flush hardware cache
to memory. This means the persistent ring buffer, which relies on a
coherent state of memory, may not have its events written to the buffer
and they may be lost. Moreover, there may be inconsistency with the
counters which are used for validation of the integrity of the
persistent ring buffer which may cause all data to be discarded.
To avoid this issue, stop recording of the ring buffer on panic and
flush the cache of the ring buffer's memory.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Allow TLP Processing Hints to be enabled for RCiEPs (George Abraham
P)
- Enable AtomicOps only if we know the Root Port supports them (Gerd
Bayer)
- Don't enable AtomicOps for RCiEPs since none of them need Atomic
Ops and we can't tell whether the Root Complex would support them
(Gerd Bayer)
- Leave Precision Time Measurement disabled until a driver enables it
to avoid PCIe errors (Mika Westerberg)
- Make pci_set_vga_state() fail if bridge doesn't support VGA
routing, i.e., PCI_BRIDGE_CTL_VGA is not writable, and return
errors to vga_get() callers including userspace via
/dev/vga_arbiter (Simon Richter)
- Validate max-link-speed from DT in j721e, brcmstb, mediatek-gen3,
rzg3s drivers (where the actual controller constraints are known),
and remove validation from the generic OF DT accessor (Hans Zhang)
- Remove pc110pad driver (no longer useful after 486 CPU support
removed) and no_pci_devices() (pc110pad was the last user) (Dmitry
Torokhov, Heiner Kallweit)
Resource management:
- Prevent assigning space to unimplemented bridge windows; previously
we mistakenly assumed prefetchable window existed and assigned
space and put a BAR there (Ahmed Naseef)
- Avoid shrinking bridge windows to fit in the initial Root Port
window; fixes one problem with devices with large BARs connected
via switches, e.g., Thunderbolt (Ilpo Järvinen)
- Pass full extent of empty space, not just the aligned space, to
resource_alignf callback so free space before the requested
alignment can be used (Ilpo Järvinen)
- Place small resources before larger ones for better utilization of
address space (Ilpo Järvinen)
- Fix alignment calculation for resource size larger than align,
e.g., bridge windows larger than the 1MB required alignment (Ilpo
Järvinen)
Reset:
- Update slot handling so all ARI functions are treated as being in
the same slot. They're all reset by Secondary Bus Reset, but
previously drivers of ARI functions that appeared to be on a
non-zero device weren't notified and fatal hardware errors could
result (Keith Busch)
- Make sysfs reset_subordinate hotplug safe to avoid spurious hotplug
events (Keith Busch)
- Hide Secondary Bus Reset ('bus') from sysfs reset_methods if masked
by CXL because it has no effect (Vidya Sagar)
- Avoid FLR for AMD NPU device, where it causes the device to hang
(Lizhi Hou)
Error handling:
- Clear only error bits in PCIe Device Status to avoid accidentally
clearing Emergency Power Reduction Detected (Shuai Xue)
- Check for AER errors even in devices without drivers (Lukas Wunner)
- Initialize ratelimit info so DPC and EDR paths log AER error
information (Kuppuswamy Sathyanarayanan)
Power control:
- Add UPD720201/UPD720202 USB 3.0 xHCI Host Controller .compatible so
generic pwrctrl driver can control it (Neil Armstrong)
Hotplug:
- Set LED_HW_PLUGGABLE for NPEM hotplug-capable ports so LED core
doesn't complain when setting brightness fails because the endpoint
is gone (Richard Cheng)
Peer-to-peer DMA:
- Allow wildcards in list of host bridges that support peer-to-peer
DMA between hierarchy domains and add all Google SoCs (Jacob
Moroni)
Endpoint framework:
- Advertise dynamic inbound mapping support in pci-epf-test and
update host pci_endpoint_test to skip doorbell testing if not
advertised by endpoint (Koichiro Den)
- Return 0, not remaining timeout, when MHI eDMA ops complete so
mhi_ep_ring_add_element() doesn't interpret non-zero as failure
(Daniel Hodges)
- Remove vntb and ntb duplicate resource teardown that leads to oops
when .allow_link() fails or .drop_link() is called (Koichiro Den)
- Disable vntb delayed work before clearing BAR mappings and
doorbells to avoid oops caused by doing the work after resources
have been torn down (Koichiro Den)
- Add a way to describe reserved subregions within BARs, e.g.,
platform-owned fixed register windows, and use it for the RK3588
BAR4 DMA ctrl window (Koichiro Den)
- Add BAR_DISABLED for BARs that will never be available to an EPF
driver, and change some BAR_RESERVED annotations to BAR_DISABLED
(Niklas Cassel)
- Add NTB .get_dma_dev() callback for cases where DMA API requires a
different device, e.g., vNTB devices (Koichiro Den)
- Add reserved region types for MSI-X Table and PBA so Endpoint
controllers can them as describe hardware-owned regions in a
BAR_RESERVED BAR (Manikanta Maddireddy)
- Make Tegra194/234 BAR0 programmable and remove 1MB size limit
(Manikanta Maddireddy)
- Expose Tegra BAR2 (MSI-X) and BAR4 (DMA) as 64-bit BAR_RESERVED
(Manikanta Maddireddy)
- Add Tegra194 and Tegra234 device table entries to pci_endpoint_test
(Manikanta Maddireddy)
- Skip the BAR subrange selftest if there are not enough inbound
window resources to run the test (Christian Bruel)
New native PCIe controller drivers:
- Add DT binding and driver for Andes QiLai SoC PCIe host controller
(Randolph Lin)
- Add DT binding and driver for ESWIN PCIe Root Complex (Senchuan
Zhang)
Baikal T-1 PCIe controller driver:
- Remove driver since it never quite became usable (Andy Shevchenko)
Cadence PCIe controller driver:
- Implement byte/word config reads with dword (32-bit) reads because
some Cadence controllers don't support sub-dword accesses (Aksh
Garg)
CIX Sky1 PCIe controller driver:
- Add 'power-domains' to DT binding for SCMI power domain (Gary Yang)
Freescale i.MX6 PCIe controller driver:
- Add i.MX94 and i.MX943 to fsl,imx6q-pcie-ep DT binding (Richard
Zhu)
- Delay instead of polling for L2/L3 Ready after PME_Turn_off when
suspending i.MX6SX because LTSSM registers are inaccessible
(Richard Zhu)
- Separate PERST# assertion (for resetting endpoints) from core reset
(for resetting the RC itself) to prepare for new DTs with PERST#
GPIO in per-Root Port nodes (Sherry Sun)
- Retain Root Port MSI capability on i.MX7D, i.MX8MM, and i.MX8MQ so
MSI from downstream devices will work (Richard Zhu)
- Fix i.MX95 reference clock source selection when internal refclk is
used (Franz Schnyder)
Freescale Layerscape PCIe controller driver:
- Allow building as a removable module (Sascha Hauer)
MediaTek PCIe Gen3 controller driver:
- Use dev_err_probe() to simplify error paths and make deferred probe
messages visible in /sys/kernel/debug/devices_deferred (Chen-Yu
Tsai)
- Power off device if setup fails (Chen-Yu Tsai)
- Integrate new pwrctrl API to enable power control for WiFi/BT
adapters on mainboard or in PCIe or M.2 slots (Chen-Yu Tsai)
NVIDIA Tegra194 PCIe controller driver:
- Poll less aggressively and non-atomically for PME_TO_Ack during
transition to L2 (Vidya Sagar)
- Disable LTSSM after transition to Detect on surprise link down to
stop toggling between Polling and Detect (Manikanta Maddireddy)
- Don't force the device into the D0 state before L2 when suspending
or shutting down the controller (Vidya Sagar)
- Disable PERST# IRQ only in Endpoint mode because it's not
registered in Root Port mode (Manikanta Maddireddy)
- Handle 'nvidia,refclk-select' as optional (Vidya Sagar)
- Disable direct speed change in Endpoint mode so link speed change
is controlled by the host (Vidya Sagar)
- Set LTR values before link up to avoid bogus LTR messages with 0
latency (Vidya Sagar)
- Allow system suspend when the Endpoint link is down (Vidya Sagar)
- Use DWC IP core version, not Tegra custom values, to avoid DWC core
version check warnings (Manikanta Maddireddy)
- Apply ECRC workaround to devices based on DesignWare 5.00a as well
as 4.90a (Manikanta Maddireddy)
- Disable PM Substate L1.2 in Endpoint mode to work around Tegra234
erratum (Vidya Sagar)
- Delay post-PERST# cleanup until core is powered on to avoid CBB
timeout (Manikanta Maddireddy)
- Assert CLKREQ# so switches that forward it to their downstream side
can bring up those links successfully (Vidya Sagar)
- Calibrate pipe to UPHY for Endpoint mode to reset stale PLL state
from any previous bad link state (Vidya Sagar)
- Remove IRQF_ONESHOT flag from Endpoint interrupt registration so
DMA driver and Endpoint controller driver can share the interrupt
line (Vidya Sagar)
- Enable DMA interrupt to support DMA in both Root Port and Endpoint
modes (Vidya Sagar)
- Enable hardware link retraining after link goes down in Endpoint
mode (Vidya Sagar)
- Add DT binding and driver support for core clock monitoring (Vidya
Sagar)
Qualcomm PCIe controller driver:
- Advertise 'Hot-Plug Capable' and set 'No Command Completed Support'
since Qcom Root Ports support hotplug events like DL_Up/Down and
can accept writes to Slot Control without delays between writes
(Krishna Chaitanya Chundru)
Renesas R-Car PCIe controller driver:
- Mark Endpoint BAR0 and BAR2 as Resizable (Koichiro Den)
- Reduce EPC BAR alignment requirement to 4K (Koichiro Den)
Renesas RZ/G3S PCIe controller driver:

- Assert (not deassert) resets in probe error path (John Madieu)
- Assert resets in suspend path in reverse order they were deasserted
during probe (John Madieu)
- Rework inbound window algorithm to prevent mapping more than
intended region and enforce alignment on size, to prepare for

crypto: Remove michael_mic from crypto_shash API
Remove the "michael_mic" crypto_shash algorithm, since it's no longer used. Its only users were wireless drivers, which have now been converted to use the michael_mic() function instead. It makes sense that no other users ever appeared: Michael MIC is an insecure algorithm that is specific to WPA TKIP, which itself was an interim security solution to replace the broken WEP standard.

arch, mm: consolidate empty_zero_page
Reduce 22 declarations of empty_zero_page to 3 and 23 declarations of ZERO_PAGE() to 4. Every architecture defines empty_zero_page that way or another, but for the most of them it is always a page aligned page in BSS and most definitions of ZERO_PAGE do virt_to_page(empty_zero_page). Move Linus vetted x86 definition of empty_zero_page and ZERO_PAGE() to the core MM and drop these definitions in architectures that do not implement colored zero page (MIPS and s390). ZERO_PAGE() remains a macro because turning it to a wrapper for a static inline causes severe pain in header dependencies. For the most part the change is mechanical, with these being noteworthy: * alpha: aliased empty_zero_page with ZERO_PGE that was also used for boot parameters. Switching to a generic empty_zero_page removes the aliasing and keeps ZERO_PGE for boot parameters only * arm64: uses __pa_symbol() in ZERO_PAGE() so that definition of ZERO_PAGE() is kept intact. * m68k/parisc/um: allocated empty_zero_page from memblock, although they do not support zero page coloring and having it in BSS will work fine. * sparc64 can have empty_zero_page in BSS rather allocate it, but it can't use virt_to_page() for BSS. Keep it's definition of ZERO_PAGE() but instead of allocating it, make mem_map_zero point to empty_zero_page. * sh: used empty_zero_page for boot parameters at the very early boot. Rename the parameters page to boot_params_page and let sh use the generic empty_zero_page. * hexagon: had an amusing comment about empty_zero_page /* A handy thing to have if one has the RAM. Declared in head.S */ that unfortunately had to go :) Link: https://lkml.kernel.org/r/20260211103141.3215197-4-rppt@kernel.org Signed-off-by: Mike Rapoport (Microsoft) <rppt@kernel.org> Acked-by: Helge Deller <deller@gmx.de> [parisc] Tested-by: Helge Deller <deller@gmx.de> [parisc] Reviewed-by: Christophe Leroy (CS GROUP) <chleroy@kernel.org> Acked-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Acked-by: Magnus Lindholm <linmag7@gmail.com> [alpha] Acked-by: Dinh Nguyen <dinguyen@kernel.org> [nios2] Acked-by: Andreas Larsson <andreas@gaisler.com> [sparc] Acked-by: David Hildenbrand (Arm) <david@kernel.org> Acked-by: Liam R.

PCI: Align head space better
When a bridge window contains big and small resource(s), the small resource(s) may not amount to the half of the size of the big resource which would allow calculate_head_align() to shrink the head alignment. This results in always placing the small resource(s) after the big resource. In general, it would be good to be able to place the small resource(s) before the big resource to achieve better utilization of the address space. In the cases where the large resource can only fit at the end of the window, it is even required. However, carrying the information over from pbus_size_mem() and calculate_head_align() to __pci_assign_resource() and pcibios_align_resource() is not easy with the current data structures. A somewhat hacky way to move the non-aligning tail part to the head is possible within pcibios_align_resource(). The free space between the start of the free space span and the aligned start address can be compared with the non-aligning remainder of the size. If the free space is larger than the remainder, placing the remainder before the start address is possible. This relocation should generally work, because PCI resources consist only power-of-2 atoms. Various arch requirements may still need to override the relocation, so the relocation is only applied selectively in such cases.

resource: Pass full extent of empty space to resource_alignf callback
__find_resource_space() calculates the full extent of empty space but only passes the aligned space to resource_alignf callback. In some situations, the callback may choose take advantage of the free space before the requested alignment. Pass the full extent of the calculated empty space to resource_alignf callback as an additional parameter.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments
This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> |

Convert 'alloc_obj' family to use the new default GFP_KERNEL argument
This was done entirely with mindless brute force, using
git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'
to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.
Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.
For the same reason the 'flex' versions will be done as a separate
conversion.

treewide: Replace kmalloc with kmalloc_obj for non-scalar types
This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook <kees@kernel.org> |

arch, mm: consolidate initialization of SPARSE memory model
Every architecture calls sparse_init() during setup_arch() although the data structures created by sparse_init() are not used until the initialization of the core MM. Beside the code duplication, calling sparse_init() from architecture specific code causes ordering differences of vmemmap and HVO initialization on different architectures. Move the call to sparse_init() from architecture specific code to free_area_init() to ensure that vmemmap and HVO initialization order is always the same.

arch, mm: consolidate initialization of nodes, zones and memory map
To initialize node, zone and memory map data structures every architecture calls free_area_init() during setup_arch() and passes it an array of zone limits. Beside code duplication it creates "interesting" ordering cases between allocation and initialization of hugetlb and the memory map. Some architectures allocate hugetlb pages very early in setup_arch() in certain cases, some only create hugetlb CMA areas in setup_arch() and sometimes hugetlb allocations happen mm_core_init(). With arch_zone_limits_init() helper available now on all architectures it is no longer necessary to call free_area_init() from architecture setup code. Rather core MM initialization can call arch_zone_limits_init() in a single place. This allows to unify ordering of hugetlb vs memory map allocation and initialization. Remove the call to free_area_init() from architecture specific code and place it in a new mm_core_init_early() function that is called immediately after setup_arch(). After this refactoring it is possible to consolidate hugetlb allocations and eliminate differences in ordering of hugetlb and memory map initialization among different architectures. As the first step of this consolidation move hugetlb_bootmem_alloc() to mm_core_early_init().

sh: introduce arch_zone_limits_init()

Later MM core will use this function as an architecture specific callback during nodes and zones initialization and thus there won't be a need to call free_area_init() from every architecture.

rseq: Implement sys_rseq_slice_yield()
Provide a new syscall which has the only purpose to yield the CPU after the kernel granted a time slice extension. sched_yield() is not suitable for that because it unconditionally schedules, but the end of the time slice extension is not required to schedule when the task was already preempted. This also allows to have a strict check for termination to catch user space invoking random syscalls including sched_yield() from a time slice extension region.

sound fixes for 6.19-rc1
The rest for 6.19 merge window. The only slightly large change is
the enablement of CIX HD-audio controller, which took a bit time to
be cooked up, while most of other changes are device-specific small
trivial fixes.
- Default disablement of the kconfig for decades old pre-release
alsa-lib PCM API; it's only the default config value change, so
it can't lead to any regressions for the existing setups
- Support for CIX HD-audio controller
- A few ASoC ACP fixes
- Fixes for ASoC cirrus, bcm, wcd, qcom, ak platforms
- Trivial hardening for FireWire and USB-audio
- HD-audio Intel binding fix and quirks

Core kernel bug handling infrastructure changes for v6.19:
- Improve WARN(), which has vararg printf like arguments,
to work with the x86 #UD based WARN-optimizing infrastructure
by hiding the format in the bug_table and replacing this
first argument with the address of the bug-table entry,
while making the actual function that's called a UD1 instruction.
(Peter Zijlstra)
- Introduce the CONFIG_DEBUG_BUGVERBOSE_DETAILED Kconfig switch
(Ingo Molnar, s390 support by Heiko Carstens)
Fixes and cleanups:
- bugs/s390: Remove private WARN_ON() implementation (Heiko Carstens)
- <asm/bugs.h>: Make i386 use GENERIC_BUG_RELATIVE_POINTERS

crypto: ansi_cprng - Remove unused ansi_cprng algorithm
Remove ansi_cprng, since it's obsolete and unused, as confirmed at https://lore.kernel.org/r/aQxpnckYMgAAOLpZ@gondor.apana.org.au/ This was originally added in 2008, apparently as a FIPS approved random number generator. Whether this has ever belonged upstream is questionable. Either way, ansi_cprng is no longer usable for this purpose, since it's been superseded by the more modern algorithms in crypto/drbg.c, and FIPS itself no longer allows it. (NIST SP 800-131A Rev 1 (2015) says that RNGs based on ANSI X9.31 will be disallowed after 2015. NIST SP 800-131A Rev 2 (2019) confirms they are now disallowed.) Therefore, there is no reason to keep it around.

syscore: Pass context data to callbacks
Several drivers can benefit from registering per-instance data along with the syscore operations. To achieve this, move the modifiable fields out of the syscore_ops structure and into a separate struct syscore that can be registered with the framework. Add a void * driver data field for drivers to store contextual data that will be passed to the syscore ops. Acked-by: Rafael J.

Remove long-stale ext3 defconfig option
Inspired by commit |

Linus Torvalds
|
66f8e4df00 |
Ext4 bug fixes for 6.18-rc2, including
* Fix regression caused by removing CONFIG_EXT3_FS when testing some
very old defconfigs
* Avoid a BUG_ON when opening a file on a maliciously corrupted file system
* Avoid mm warnings when freeing a very large orphan file metadata
* Avoid a theoretical races between metadata wrtteback and checkpoints.
(It's very hard to hit in practice, since the race requires that the
writeback take a very long time.)
