remoteproc updates for v5.13
This adds support to the remoteproc core for detaching Linux from a running remoteproc, e.g. to reboot Linux while leaving the remoteproc running, and it enable this support in the stm32 remoteproc driver. It also introduces a property for memory carveouts to track if they are iomem or system ram, to enable proper handling of the differences. The imx_rproc received a number of fixes and improvements, in particular support for attaching to already running remote processors and i.MX8MQ and i.MX8MM support. The Qualcomm wcss driver gained support for starting and stopping the wireless subsystem on QCS404, when not using the TrustZone-based validator/loader. Finally it brings a few fixes to the TI PRU and to the firmware loader for the Qualcomm modem subsystem drivers. -----BEGIN PGP SIGNATURE----- iQJPBAABCAA5FiEEBd4DzF816k8JZtUlCx85Pw2ZrcUFAmCRX8IbHGJqb3JuLmFu ZGVyc3NvbkBsaW5hcm8ub3JnAAoJEAsfOT8Nma3F+AoP/3g7Kj5mri3YpB/0IRhG bTQWihFow+Ez03kBV4drMdTwDI3FToh/LEJNBUTRzXgVGTOzjf0SSLYr2wD/QCz1 mPFYDZZBAkgA1tyhABgPEFKGweMw2mV1Jntw6L4zid7q2YzSyz+abheSumOgL8Kb ub/0k3+1AiymxivYQrUtH9/nndkJ7U/VxGiIlmCWiJ9qAXUpvGmZ0SGljPZZ3SoA ul/gBrUeYnCfv7JebzLFPoMhkdpB8bj8OmleAm7tqbEkLq2qeY1AcZ/EZfhNrAPC z4IdSvfc9d7xttLcEKGcayG0sUKINoCI3CQkd4hzvfAV86fBgqPb9FcXhm6LVs6W sqOjEJiZbhP5x0sCWw0YGFHlWeD6gxCT6lvqfFLOSFTrbMqhnY2/nNK/kypWwFKs Xz+eEIQWb2u1tyLq2SernTKbBCFylk7CqNKXJuIMcpZpMzxP5SIa9G0Ooc3O0gQV cjXwNTdqwJPADdb7baA7Wrw56Aov1FQT3cOmkJrFrIHZW81Ja1Djf59aZgpwmTSb vH6c7NZJXeSobhzc/Q/mLQlvK+bMviufQRB0ccBtt3cqDibWPPbwyqN8vtFbcqA0 P+VK+zL3ZVXFAFsBf/T+WLKQOJ/8AxqElFHEdQvyOruyKafuYgyy99IQQOwqgm/h OzNdtmevgEz9j+ywKk89J0V2 =er2q -----END PGP SIGNATURE----- Merge tag 'rproc-v5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc Pull remoteproc updates from Bjorn Andersson: "This adds support to the remoteproc core for detaching Linux from a running remoteproc, e.g. to reboot Linux while leaving the remoteproc running, and it enable this support in the stm32 remoteproc driver.

tracing updates for 5.13
New feature:
The "func-no-repeats" option in tracefs/options directory. When set
the function tracer will detect if the current function being traced
is the same as the previous one, and instead of recording it, it will
keep track of the number of times that the function is repeated in a row.
And when another function is recorded, it will write a new event that
shows the function that repeated, the number of times it repeated and
the time stamp of when the last repeated function occurred.
Enhancements:
In order to implement the above "func-no-repeats" option, the ring
buffer timestamp can now give the accurate timestamp of the event
as it is being recorded, instead of having to record an absolute
timestamp for all events. This helps the histogram code which no longer
needs to waste ring buffer space.
New validation logic to make sure all trace events that access
dereferenced pointers do so in a safe way, and will warn otherwise.
Fixes:
No longer limit the PIDs of tasks that are recorded for "saved_cmdlines"
to PID_MAX_DEFAULT (32768), as systemd now allows for a much larger
range. This caused the mapping of PIDs to the task names to be dropped
for all tasks with a PID greater than 32768.
Change trace_clock_global() to never block. This caused a deadlock.
Clean ups:
Typos, prototype fixes, and removing of duplicate or unused code.
Better management of ftrace_page allocations.

orangefs: implement orangefs_readahead
mm/readahead.c/read_pages was quite a bit different back
when I put my open-coded readahead logic into orangefs_readpage.
It seemed to work as designed then, it is a trainwreck now.
This patch implements orangefs_readahead using new xarray
and readahead_expand features that have just been pulled and
removes all my open-coded readahead logic.
This patch results in an extreme read performance improvement,
these sample numbers are from my test VM:
Here's an example of what's upstream in
5.11.8-200.fc33.x86_64:
30+0 records in
30+0 records out
125829120 bytes (126 MB, 120 MiB) copied, 5.77943 s, 21.8 MB/s
And here's this version of orangefs_readahead on top of
5.12.0-rc4:
30+0 records in
30+0 records out
125829120 bytes (126 MB, 120 MiB) copied, 0.325919 s, 386 MB/s
There are four xfstest regressions with this patch. David Howells
and Matthew Wilcox have been helping me work with this code. One
of the regressions has gone away with the most recent version of
their code that I'm using. I hope this patch can be
pulled even though there are still a few regressions, and that
we can try to get them resolved during the RC period.

Pull Landlock LSM from James Morris:
"Add Landlock, a new LSM from Mickaël Salaün.
Briefly, Landlock provides for unprivileged application sandboxing.
From Mickaël's cover letter:
"The goal of Landlock is to enable to restrict ambient rights (e.g.
global filesystem access) for a set of processes. Because Landlock
is a stackable LSM [1], it makes possible to create safe security
sandboxes as new security layers in addition to the existing
system-wide access-controls. This kind of sandbox is expected to
help mitigate the security impact of bugs or unexpected/malicious
behaviors in user-space applications. Landlock empowers any
process, including unprivileged ones, to securely restrict
themselves.
Landlock is inspired by seccomp-bpf but instead of filtering
syscalls and their raw arguments, a Landlock rule can restrict the
use of kernel objects like file hierarchies, according to the
kernel semantic. Landlock also takes inspiration from other OS
sandbox mechanisms: XNU Sandbox, FreeBSD Capsicum or OpenBSD
Pledge/Unveil.
In this current form, Landlock misses some access-control features.
This enables to minimize this patch series and ease review. This
series still addresses multiple use cases, especially with the
combined use of seccomp-bpf: applications with built-in sandboxing,
init systems, security sandbox tools and security-oriented APIs [2]"

afs: Fix speculative status fetches
The generic/464 xfstest causes kAFS to emit occasional warnings of the
form:
kAFS: vnode modified {100055:8a} 30->31 YFS.StoreData64 (c=6015)
This indicates that the data version received back from the server did not
match the expected value (the DV should be incremented monotonically for
each individual modification op committed to a vnode).
What is happening is that a lookup call is doing a bulk status fetch
speculatively on a bunch of vnodes in a directory besides getting the
status of the vnode it's actually interested in. This is racing with a
StoreData operation (though it could also occur with, say, a MakeDir op).
On the client, a modification operation locks the vnode, but the bulk
status fetch only locks the parent directory, so no ordering is imposed
there (thereby avoiding an avenue to deadlock).
On the server, the StoreData op handler doesn't lock the vnode until it's
received all the request data, and downgrades the lock after committing the
data until it has finished sending change notifications to other clients -
which allows the status fetch to occur before it has finished.
This means that:
- a status fetch can access the target vnode either side of the exclusive
section of the modification
- the status fetch could start before the modification, yet finish after,
and vice-versa.
- the status fetch and the modification RPCs can complete in either order.
- the status fetch can return either the before or the after DV from the
modification.
- the status fetch might regress the locally cached DV.
Some of these are handled by the previous fix[1], but that's not sufficient
because it checks the DV it received against the DV it cached at the start
of the op, but the DV might've been updated in the meantime by a locally
generated modification op.
Fix this by the following means:
(1) Keep track of when we're performing a modification operation on a
vnode. This is done by marking vnode parameters with a 'modification'
note that causes the AFS_VNODE_MODIFYING flag to be set on the vnode
for the duration.
(2) Alter the speculation race detection to ignore speculative status
fetches if either the vnode is marked as being modified or the data
version number is not what we expected.
Note that whilst the "vnode modified" warning does get recovered from as it
causes the client to refetch the status at the next opportunity, it will
also invalidate the pagecache, so changes might get lost.
Fixes:

- Improve scalability of DM's device hash by switching to rbtree
- Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and
allow filtering based on name or UUID prefix.
- Various small fixes for typos, warnings, unused function, or
needlessly exported interfaces.
- Remove needless request_queue NULL pointer checks in DM thin and
cache targets.
- Remove unnecessary loop in DM core's __split_and_process_bio().
- Remove DM core's dm_vcalloc() and just use kvcalloc or
kvmalloc_array instead (depending whether zeroing is useful).
- Fix request-based DM's double free of blk_mq_tag_set in device
remove after table load fails.
- Improve DM persistent data performance on non-x86 by fixing packed
structs to have a stated alignment. Also remove needless extra work
from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON()
that caused duplicate checksum calculation.
- Fix missing goto in DM integrity's bitmap_flush_interval error
handling.
- Add "reset_recalculate" feature flag to DM integrity.
- Improve DM integrity by leveraging discard support to avoid needless
re-writing of metadata and also use discard support to improve
hash recalculation.
- Fix race with DM raid target's reshape and MD raid4/5/6 resync that
resulted in inconsistant reshape state during table reloads.
- Update DM raid target to temove unnecessary discard limits for raid0
and raid10 now that MD has optimized discard handling for both raid
levels.

Merge tag 'for-5.13/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer:
- Improve scalability of DM's device hash by switching to rbtree
- Extend DM ioctl's DM_LIST_DEVICES_CMD handling to include UUID and
allow filtering based on name or UUID prefix.
- Various small fixes for typos, warnings, unused function, or
needlessly exported interfaces.
- Remove needless request_queue NULL pointer checks in DM thin and
cache targets.
- Remove unnecessary loop in DM core's __split_and_process_bio().
- Remove DM core's dm_vcalloc() and just use kvcalloc or kvmalloc_array
instead (depending whether zeroing is useful).
- Fix request-based DM's double free of blk_mq_tag_set in device remove
after table load fails.
- Improve DM persistent data performance on non-x86 by fixing packed
structs to have a stated alignment. Also remove needless extra work
from redundant calls to sm_disk_get_nr_free() and a paranoid BUG_ON()
that caused duplicate checksum calculation.
- Fix missing goto in DM integrity's bitmap_flush_interval error
handling.
- Add "reset_recalculate" feature flag to DM integrity.
- Improve DM integrity by leveraging discard support to avoid needless
re-writing of metadata and also use discard support to improve hash
recalculation.
- Fix race with DM raid target's reshape and MD raid4/5/6 resync that
resulted in inconsistant reshape state during table reloads.
- Update DM raid target to temove unnecessary discard limits for raid0
and raid10 now that MD has optimized discard handling for both raid
levels.

IOMMU Updates for Linux v5.13
Including:
- Big cleanup of almost unsused parts of the IOMMU API by
Christoph Hellwig. This mostly affects the Freescale PAMU
driver.
- New IOMMU driver for Unisoc SOCs
- ARM SMMU Updates from Will:
- SMMUv3: Drop vestigial PREFETCH_ADDR support
- SMMUv3: Elide TLB sync logic for empty gather
- SMMUv3: Fix "Service Failure Mode" handling
- SMMUv2: New Qualcomm compatible string
- Removal of the AMD IOMMU performance counter writeable check
on AMD. It caused long boot delays on some machines and is
only needed to work around an errata on some older (possibly
pre-production) chips. If someone is still hit by this
hardware issue anyway the performance counters will just
return 0.
- Support for targeted invalidations in the AMD IOMMU driver.
Before that the driver only invalidated a single 4k page or the
whole IO/TLB for an address space. This has been extended now
and is mostly useful for emulated AMD IOMMUs.
- Several fixes for the Shared Virtual Memory support in the
Intel VT-d driver
- Mediatek drivers can now be built as modules
- Re-introduction of the forcedac boot option which got lost
when converting the Intel VT-d driver to the common dma-iommu
implementation.
- Extension of the IOMMU device registration interface and
support iommu_ops to be const again when drivers are built as
modules.

This is the bulk of the pin control changes for the v5.13 kernel cycle
Core changes:
- A semantic change to handle pinmux and pinconf in explicit order
while up until now we depended on the semantic order in the
device tree. The device tree is a functional programming
language and does not imply any order, so the right thing is
for the pin control core to provide these semantics.
- Add a new pinmux-select debugfs file which makes it possible to
go in and select functions for a pin manually (iteratively, at
the prompt) for debugging purposes.
- Fixes to gpio regmap handling for a new pin control driver
making use of regmap-gpio.
- Use octal permissions on debugfs files.
New drivers:
- A massive rewrite of the former custom pin control driver for
MIPS Broadcom devices to instead use the pin control subsystem.
New pin control drivers for BCM6345, BCM6328, BCM6358, BCM6362,
BCM6368, BCM63268 and BCM6318 SoC variants are implemented.
- Support for PM8350, PM8350B, PM8350C, PMK8350, PMR735A and
PMR735B in the Qualcomm PMIC GPIO driver. Also the two GPIOs
on PM8008 are supported.
- Support for the Rockchip RK3568/RK3566 pin controller.
- Support for Ingenic JZ4730, JZ4750, JZ4755, JZ4775 and
X2000.
- Support for Mediatek MTK8195.
- Add a new Xilinx ZynqMP pin control driver.
Driver improvements and non-urgent fixes:
- Modularization and improvements of the Rockchip drivers.
- Some new pins added to the description of new Renesas SoCs.
- Clarifications of the GPIO base calculation in the Intel driver.
- Fix the function names for the MPP54 and MPP55 pins in the Armada
CP110 pin controller.
- GPIO wakeup interrupt map for Qualcomm SC7280 and SM8350.
- Support for ACPI probing of the Qualcomm SC8180x.
- Fix interrupt clear status on rockchip
- Fix some missing pins on the Ingenic JZ4770, some semantic
fixes for the behaviour of the Ingenic pin controller.
Add DMIC pins for JZ4780, X1000, X1500 and X1830.
- A slew of janitorial like of_node_put() calls.

sound updates for 5.13
No surprises in this development cycle, and most of works are about
the fixes and the improvements of the existing code, while a new LED
control layer and a few new drivers have been introduced.
Here are some highlights:
Core:
- A common mute-LED framework was introduced;
used by HD-audio for now, more adaption will follow later.
The former "Mic Mute-LED Mode" mixer control has been replaced with
the corresponding sysfs now.
- User-control management was changed to count consumed bytes instead
of capping by number of elements;
this will allow more controls in the normal usage pattern while
avoiding the possible memory exhaustion DoS
ASoC:
- Continued refactoring and cleanups in ASoC core and generic card
drivers
- Wide range of small cppcheck and warning fixes
- New drivers for Freescale i.MX DMA over rpmsg, Mediatek MT6358
accessory detection, and Realtek RT1019, RT1316, RT711 and RT715
USB-audio:
- Continued improvements and fixes of the implicit feedback mode,
including better support for Pioneer and Roland/BOSS devices
HD-audio:
- Default back to non-buffer preallocation on x86
- Cirrus codec improvements, more quirks for Realtek codecs
Others:
- New virtio sound driver
- FireWire Bebob updates
Note that this PR includes a couple of changes in reset and SPI
drivers, too, and some merge conflicts might happen.

Summary of modules changes for the 5.13 merge window:
- Fix an age old bug involving jump_calls and static_labels when
CONFIG_MODULE_UNLOAD=n. When CONFIG_MODULE_UNLOAD=n, it means you
can't unload modules, so normally the __exit sections of a module are
not loaded at all. However, dynamic code patching (jump_label,
static_call, alternatives) can have sites in __exit sections even if
__exit is never executed.
Reported by Peter Zijlstra: "Alternatives, jump_labels and static_call
all can have relocations into __exit code. Not loading it at all would
be BAD." Therefore, load the __exit sections even when
CONFIG_MODULE_UNLOAD=n, and discard them after init.

Pull module updates from Jessica Yu:
"Fix an age old bug involving jump_calls and static_labels when
CONFIG_MODULE_UNLOAD=n.
When CONFIG_MODULE_UNLOAD=n, it means you can't unload modules, so
normally the __exit sections of a module are not loaded at all.
However, dynamic code patching (jump_label, static_call, alternatives)
can have sites in __exit sections even if __exit is never executed.
Reported by Peter Zijlstra:
'Alternatives, jump_labels and static_call all can have relocations
into __exit code. Not loading it at all would be BAD.'
Therefore, load the __exit sections even when CONFIG_MODULE_UNLOAD=n,
and discard them after init"

mm/memory-failure: unnecessary amount of unmapping

argument rather than a location, the current calling fashion causes
unnecessary amount of unmapping to occur.

mm: page_alloc: ignore init_on_free=1 for debug_pagealloc=1
On !ARCH_SUPPORTS_DEBUG_PAGEALLOC (like ia64) debug_pagealloc=1 implies
page_poison=on:
if (page_poisoning_enabled() ||
(!IS_ENABLED(CONFIG_ARCH_SUPPORTS_DEBUG_PAGEALLOC) &&
debug_pagealloc_enabled()))
static_branch_enable(&_page_poisoning_enabled);
page_poison=on needs to override init_on_free=1.
Before the change it did not work as expected for the following case:
- have PAGE_POISONING=y
- have page_poison unset
- have !ARCH_SUPPORTS_DEBUG_PAGEALLOC arch (like ia64)
- have init_on_free=1
- have debug_pagealloc=1
That way we get both keys enabled:
- static_branch_enable(&init_on_free);
- static_branch_enable(&_page_poisoning_enabled);
which leads to poisoned pages returned for __GFP_ZERO pages.
After the change we execute only:
- static_branch_enable(&_page_poisoning_enabled);
and ignore init_on_free=1.

net: page_pool: use alloc_pages_bulk in refill code path
There are cases where the page_pool need to refill with pages from the page allocator. Some workloads cause the page_pool to release pages instead of recycling these pages. For these workload it can improve performance to bulk alloc pages from the page-allocator to refill the alloc cache. For XDP-redirect workload with 100G mlx5 driver (that use page_pool) redirecting xdp_frame packets into a veth, that does XDP_PASS to create an SKB from the xdp_frame, which then cannot return the page to the page_pool.

SUNRPC: set rq_page_end differently
Patch series "SUNRPC consumer for the bulk page allocator"
This patch set and the measurements below are based on yesterday's
bulk allocator series:
git://git.kernel.org/pub/scm/linux/kernel/git/mel/linux.git mm-bulk-rebase-v5r9
The patches change SUNRPC to invoke the array-based bulk allocator
instead of alloc_page().
The micro-benchmark results are promising. I ran a mixture of 256KB
reads and writes over NFSv3. The server's kernel is built with KASAN
enabled, so the comparison is exaggerated but I believe it is still
valid.
I instrumented svc_recv() to measure the latency of each call to
svc_alloc_arg() and report it via a trace point. The following results
are averages across the trace events.
Single page: 25.007 us per call over 532,571 calls
Bulk list: 6.258 us per call over 517,034 calls
Bulk array: 4.590 us per call over 517,442 calls
This patch (of 2)
Refactor:
I'm about to use the loop variable @i for something else.
As far as the "i++" is concerned, that is a post-increment. The
value of @i is not used subsequently, so the increment operator
is unnecessary and can be removed.
Also note that nfsd_read_actor() was renamed nfsd_splice_actor()

Looking at perf-report and ASM-code for __alloc_pages_bulk() it is clear that the code activated is suboptimal. The compiler guesses wrong and places unlikely code at the beginning.
