ARM fixes for 6.16-rc1
- fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to memblock_is_map_memory rather than the actual address. - "Disallow kernel mode NEON when IRQs are disabled" - this needs a better explanation. "To avoid having to preserve/restore kernel mode NEON state when such a softirq is taken softirqs are now disabled when using the NEON from task context." should explain that it's nested kernel mode. In other words, softirqs from user mode are fine, because the context will be preserved. softirqs from kernel mode may be from a context that has already saved the user NEON state, and thus we would need to preserve the NEON state for the parent kernel mode context, and this we don't allow. The problem occurs when the kernel context disables hard IRQs, and then uses NEON. When it's finished, and restores the userspace NEON state, we call local_bh_enable() with hard IRQs disabled, which causes a warning. This commit addresses that by disallowing the use of NEON with hard IRQs disabled. https://lore.kernel.org/all/20250516231858.27899-4-ebiggers@kernel.org/T/#m104841b6e9346b1814c8b0fb9f2340551b0cd3e8 has some further context. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEuNNh8scc2k/wOAE+9OeQG+StrGQFAmg9k5MACgkQ9OeQG+St rGTsIg//R8AysyZIHWCzO+j7UFZPQ+jUZ0Qf0NMA3Ss/Bh724BtDWIMRo30/ADtX nwJhGnFVenr9jdGuUBmE8R25QyfZIz2U45hGVqUgSL9W96A8PPsuaR7oXhvezq68 Wj+UUTzem4l1bgK416qEROPgY/dtYCL5AbPA+SdH+LSMvS9phkhT6PkGJRC14tZ9 kLNR4PyA9/DC6N6wIU8v9pWezSoOBn/ISBpb67BB0OzZPlmgoJJOXbSNzIHaJc4C YjjJCHRmZL2w/U4HyEc8qXyHMPggEKtDas6mwrpxV/fjoReC/vk3tvuRxy1Mt1Ny BIIOA/Hauz8O9+aqfdqABK92tMiLx7NA9bWQDndIisfD/nRFyrpFDUbw1+d4EemU qzDmKSNWK9nsC28kE8F5M4XLacHu4AQN10Ktjr5LXGoMmPfDz0xssd2uDJkbL4Zq wHVea4HPX8Ykrv6yg+iRZp54z25+ckD+kf93zhutabaa/zVdAHAU9Lk/Uqm2G1R2 5huER0vvLJF3+mYu9mRjodssOUsEVwPbBuGiwJ7DY2a6faexuJv/sU5ZyHhwHb/B TjaYbektcllYWly+KN33XzZXuVVpY9DbRq/2MCFbxMYjHxGjj7QiytTm8tI6VX26 yi8CQ+8/0SXoBPaDjb2y4n6qIxcjiBcdQ8DxDbA9Od0glzJQUhE= =V4ew -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rmk/linux Pull ARM fixes from Russell King: - Fix arch_memremap_can_ram_remap() which incorrectly passed a PFN to memblock_is_map_memory rather than the actual address. - Disallow kernel mode NEON when IRQs are disabled Explanation: "To avoid having to preserve/restore kernel mode NEON state when such a softirq is taken softirqs are now disabled when using the NEON from task context." should explain that it's nested kernel mode.

Rust changes for v6.16
Toolchain and infrastructure:
- KUnit '#[test]'s:
- Support KUnit-mapped 'assert!' macros.
The support that landed last cycle was very basic, and the
'assert!' macros panicked since they were the standard library
ones. Now, they are mapped to the KUnit ones in a similar way to
how is done for doctests, reusing the infrastructure there.
With this, a failing test like:
#[test]
fn my_first_test() {
assert_eq!(42, 43);
}
will report:
# my_first_test: ASSERTION FAILED at rust/kernel/lib.rs:251
Expected 42 == 43 to be true, but is false
# my_first_test.speed: normal
not ok 1 my_first_test
- Support tests with checked 'Result' return types.
The return value of test functions that return a 'Result' will be
checked, thus one can now easily catch errors when e.g. using the
'?' operator in tests.
With this, a failing test like:
#[test]
fn my_test() -> Result {
f()?;
Ok(())
}
will report:
# my_test: ASSERTION FAILED at rust/kernel/lib.rs:321
Expected is_test_result_ok(my_test()) to be true, but is false
# my_test.speed: normal
not ok 1 my_test
- Add 'kunit_tests' to the prelude.
- Clarify the remaining language unstable features in use.
- Compile 'core' with edition 2024 for Rust >= 1.87.
- Workaround 'bindgen' issue with forward references to 'enum' types.
- objtool: relax slice condition to cover more 'noreturn' functions.
- Use absolute paths in macros referencing 'core' and 'kernel' crates.
- Skip '-mno-fdpic' flag for bindgen in GCC 32-bit arm builds.
- Clean some 'doc_markdown' lint hits -- we may enable it later on.
'kernel' crate:
- 'alloc' module:
- 'Box': support for type coercion, e.g. 'Box<T>' to 'Box<dyn U>' if
'T' implements 'U'.
- 'Vec': implement new methods (prerequisites for nova-core and
binder): 'truncate', 'resize', 'clear', 'pop',
'push_within_capacity' (with new error type 'PushError'),
'drain_all', 'retain', 'remove' (with new error type
'RemoveError'), insert_within_capacity' (with new error type
'InsertError').
In addition, simplify 'push' using 'spare_capacity_mut', split
'set_len' into 'inc_len' and 'dec_len', add type invariant
'len <= capacity' and simplify 'truncate' using 'dec_len'.
- 'time' module:
- Morph the Rust hrtimer subsystem into the Rust timekeeping
subsystem, covering delay, sleep, timekeeping, timers. This new
subsystem has all the relevant timekeeping C maintainers listed in
the entry.
- Replace 'Ktime' with 'Delta' and 'Instant' types to represent a
duration of time and a point in time.
- Temporarily add 'Ktime' to 'hrtimer' module to allow 'hrtimer' to
delay converting to 'Instant' and 'Delta'.
- 'xarray' module:
- Add a Rust abstraction for the 'xarray' data structure. This
abstraction allows Rust code to leverage the 'xarray' to store
types that implement 'ForeignOwnable'. This support is a dependency
for memory backing feature of the Rust null block driver, which is
waiting to be merged.
- Set up an entry in 'MAINTAINERS' for the XArray Rust support.
Patches will go to the new Rust XArray tree and then via the Rust
subsystem tree for now.
- Allow 'ForeignOwnable' to carry information about the pointed-to
type. This helps asserting alignment requirements for the pointer
passed to the foreign language.
- 'container_of!': retain pointer mut-ness and add a compile-time check
of the type of the first parameter ('$field_ptr').
- Support optional message in 'static_assert!'.
- Add C FFI types (e.g. 'c_int') to the prelude.
- 'str' module: simplify KUnit tests 'format!' macro, convert
'rusttest' tests into KUnit, take advantage of the '-> Result'
support in KUnit '#[test]'s.
- 'list' module: add examples for 'List', fix path of 'assert_pinned!'
(so far unused macro rule).
- 'workqueue' module: remove 'HasWork::OFFSET'.
- 'page' module: add 'inline' attribute.
'macros' crate:
- 'module' macro: place 'cleanup_module()' in '.exit.text' section.
'pin-init' crate:
- Add 'Wrapper<T>' trait for creating pin-initializers for wrapper
structs with a structurally pinned value such as 'UnsafeCell<T>' or
'MaybeUninit<T>'.
- Add 'MaybeZeroable' derive macro to try to derive 'Zeroable', but
not error if not all fields implement it. This is needed to derive
'Zeroable' for all bindgen-generated structs.
- Add 'unsafe fn cast_[pin_]init()' functions to unsafely change the
initialized type of an initializer. These are utilized by the
'Wrapper<T>' implementations.
- Add support for visibility in 'Zeroable' derive macro.
- Add support for 'union's in 'Zeroable' derive macro.
- Upstream dev news: streamline CI, fix some bugs. Add new workflows
to check if the user-space version and the one in the kernel tree
have diverged. Use the issues tab [1] to track them, which should
help folks report and diagnose issues w.r.t. 'pin-init' better.
[1] https://github.com/rust-for-linux/pin-init/issues
Documentation:
- Testing: add docs on the new KUnit '#[test]' tests.
- Coding guidelines: explain that '///' vs. '//' applies to private
items too. Add section on C FFI types.
- Quick Start guide: update Ubuntu instructions and split them into
"25.04" and "24.04 LTS and older".
And a few other cleanups and improvements.

bcachefs updates for 6.16, part 2
- More stack usage improvements (~600 bytes).
- Define CLASS()es for some commonly used types, and convert most
rcu_read_lock() uses to the new lock guards
- New introspection:
- Superblock error counters are now available in sysfs: previously,
they were only visible with 'show-super', which doesn't provide a
live view
- New tracepoint, error_throw(), which is called any time we return an
error and start to unwind
- Repair
- check_fix_ptrs() can now repair btree node roots
- We can now repair when we've somehow ended up with the journal using
a superblock bucket
- Revert some leftovers from the aborted directory i_size feature, and
add repair code: some userspace programs (e.g. sshfs) were getting
confused.
It seems in 6.15 there's a bug where i_nlink on the vfs inode has been
getting incorrectly set to 0, with some unfortunate results;
list_journal analysis showed bch2_inode_rm() being called (by
bch2_evict_inode()) when it clearly should not have been.
- bch2_inode_rm() now runs "should we be deleting this inode?" checks
that were previously only run when deleting unlinked inodes in
recovery.
- check_subvol() was treating a dangling subvol (pointing to a missing
root inode) like a dangling dirent, and deleting it. This was the
really unfortunate one: check_subvol() will now recreate the root
inode if necessary.
This took longer to debug than it should have, and we lost several
filesystems unnecessarily, becuase users have been ignoring the release
notes and blindly running 'fsck -y'. Debugging required reconstructing
what happened through analyzing the journal, when ideally someone would
have noticed 'hey, fsck is asking me if I want to repair this: it
usually doesn't, maybe I should run this in dry run mode and check
what's going on?'.
As a reminder, fsck errors are being marked as autofix once we've
verified, in real world usage, that they're working correctly; blindly
running 'fsck -y' on an experimental filesystem is playing with fire.
Up to this incident we've had an excellent track record of not losing
data, so let's try to learn from this one.
This is a community effort, I wouldn't be able to get this done without
the help of all the people QAing and providing excellent bug reports and
feedback based on real world usage. But please don't ignore advice and
expect me to pick up the pieces.
If an error isn't marked as autofix, and it /is/ happening in the wild,
that's also something I need to know about so we can check it out and
add it to the autofix list if repair looks good. I haven't been getting
those reports, and I should be; since we don't have any sort of
telemetry yet I am absolutely dependent on user reports.
Now I'll be spending the weekend working on new repair code to see if I
can get a filesystem back for a user who didn't have backups.

bcachefs: Make journal read log message a bit quieter
Users seem to be assuming that the 'dropped unflushed entries' message at the end of journal read indicates some sort of problem, when it does not - we expect there to be entries in the journal that weren't commited, it's purely informational so that we can correlate journal sequence numbers elsewhere when debugging. Shorten the log message a bit to hopefully make this clearer. Signed-off-by: Kent Overstreet <kent.overstreet@linux.dev> |

bcachefs: Fix subvol to missing root repair
We had a bug where the root inode of a subvolume was erronously deleted: bch2_evict_inode() called bch2_inode_rm(), meaning the VFS inode's i_nlink was somehow set to 0 when it shouldn't have - the inode in the btree indicated it clearly was not unlinked. This has been addressed with additional safety checks in bch2_inode_rm() - pulling in the safety checks we already were doing when deleting unlinked inodes in recovery - but the really disastrous bug was in check_subvols(), which on finding a dangling subvol (subvol with a missing root inode) would delete the subvolume. I assume this bug dates from early check_directory_structure() code, which originally handled subvolumes and normal paths - the idea being that still live contents of the subvolume would get reattached somewhere. But that's incorrect, and disastrously so; deleting a subvolume triggers deleting the snapshot ID it points to, deleting the entire contents. The correct way to repair is to recreate the root inode if it's missing; then any contents will get reattached under that subvolume's lost+found.

bcachefs: Run may_delete_deleted_inode() checks in bch2_inode_rm()
We had a bug where bch2_evict_inode() incorrectly called bch2_inode_rm() - the journal clearly showed the inode was not unlinked.

bcachefs: Fix oops in btree_node_seq_matches()
btree_update_nodes_written() needs to wait on in-flight writes to old nodes before marking them as freed. But it has no reason to pin those old nodes in memory, so some trickyness ensues. The update we're completing deleted references to those nodes from the btree, so we know if they've been evicted they can't be pulled back in. We just have to check if the nodes we have pointers to are still those old nodes, and haven't been reused. To do that we check the node's "sequence number" (actually a random 64 bit cookie), but that lives in the node's data buffer. 'struct btree' can't be freed until filesystem shutdown (as they're quite small), but the data buffers can be freed or swapped around. Commit |

bcachefs: Fix dirent_casefold_mismatch repair
Instead of simply recreating a mis-casefolded dirent, use the str_hash repair code, which will rename it if necessary - the dirent might have been created again with the correct casefolding. Factor out out bch2_str_hash_repair key() from __bch2_str_hash_check_key() for the new path to use, and export bch2_dirent_create_key() as well.

bcachefs: Fix -Wc23-extensions in bch2_check_dirents()
Clang warns (or errors with CONFIG_WERROR=y):

2325 | int ret = bch2_trans_run(c,

On clang-17 and older, this is an unconditional error:
fs/bcachefs/fsck.c:2325:2: error: expected expression
2325 | int ret = bch2_trans_run(c,

Move the declaration of ret to the top of the function to resolve both
ways this issue manifests.

sched_ext: Fixes for v6.16-rc1
Two fixes in the built-in idle selection helpers.
- Fix prev_cpu handling to guarantee that idle selection never returns a CPU
that's not allowed.
- Skip cross-node search when !NUMA which could lead to infinite looping due
to a bug in NUMA iterator.

Pull pci updates from Bjorn Helgaas:
"Enumeration:
- Print the actual delay time in pci_bridge_wait_for_secondary_bus()
instead of assuming it was 1000ms (Wilfred Mallawa)
- Revert 'iommu/amd: Prevent binding other PCI drivers to IOMMU PCI
devices', which broke resume from system sleep on AMD platforms and
has been fixed by other commits (Lukas Wunner)
Resource management:
- Remove mtip32xx use of pcim_iounmap_regions(), which is deprecated
and unnecessary (Philipp Stanner)
- Remove pcim_iounmap_regions() and pcim_request_region_exclusive()
and related flags since all uses have been removed (Philipp
Stanner)
- Rework devres 'request' functions so they are no longer 'hybrid',
i.e., their behavior no longer depends on whether
pcim_enable_device or pci_enable_device() was used, and remove
related code (Philipp Stanner)
- Warn (not BUG()) about failure to assign optional resources (Ilpo
Järvinen)
Error handling:
- Log the DPC Error Source ID only when it's actually valid (when
ERR_FATAL or ERR_NONFATAL was received from a downstream device)
and decode into bus/device/function (Bjorn Helgaas)
- Determine AER log level once and save it so all related messages
use the same level (Karolina Stolarek)
- Use KERN_WARNING, not KERN_ERR, when logging PCIe Correctable
Errors (Karolina Stolarek)
- Ratelimit PCIe Correctable and Non-Fatal error logging, with sysfs
controls on interval and burst count, to avoid flooding logs and
RCU stall warnings (Jon Pan-Doh)
Power management:
- Increment PM usage counter when probing reset methods so we don't
try to read config space of a powered-off device (Alex Williamson)
- Set all devices to D0 during enumeration to ensure ACPI opregion is
connected via _REG (Mario Limonciello)
Power control:
- Rename pwrctrl Kconfig symbols from 'PWRCTL' to 'PWRCTRL' to match
the filename paths. Retain old deprecated symbols for
compatibility, except for the pwrctrl slot driver
(PCI_PWRCTRL_SLOT) (Johan Hovold)
- When unregistering pwrctrl, cancel outstanding rescan work before
cleaning up data structures to avoid use-after-free issues (Brian
Norris)
Bandwidth control:
- Simplify link bandwidth controller by replacing the count of Link
Bandwidth Management Status (LBMS) events with a PCI_LINK_LBMS_SEEN
flag (Ilpo Järvinen)
- Update the Link Speed after retraining, since the Link Speed may
have changed (Ilpo Järvinen)
PCIe native device hotplug:
- Ignore Presence Detect Changed caused by DPC.
pciehp already ignores Link Down/Up events caused by DPC, but on
slots using in-band presence detect, DPC causes a spurious Presence
Detect Changed event (Lukas Wunner)
- Ignore Link Down/Up caused by Secondary Bus Reset.
On hotplug ports using in-band presence detect, the reset causes a
Presence Detect Changed event, which mistakenly caused teardown and
re-enumeration of the device. Drivers may need to annotate code
that resets their device (Lukas Wunner)
Virtualization:
- Add an ACS quirk for Loongson Root Ports that don't advertise ACS
but don't allow peer-to-peer transactions between Root Ports; the
quirk allows each Root Port to be in a separate IOMMU group (Huacai
Chen)
Endpoint framework:
- For fixed-size BARs, retain both the actual size and the possibly
larger size allocated to accommodate iATU alignment requirements
(Jerome Brunet)
- Simplify ctrl/SPAD space allocation and avoid allocating more space
than needed (Jerome Brunet)
- Correct MSI-X PBA offset calculations for DesignWare and Cadence
endpoint controllers (Niklas Cassel)
- Align the return value (number of interrupts) encoding for
pci_epc_get_msi()/pci_epc_ops::get_msi() and
pci_epc_get_msix()/pci_epc_ops::get_msix() (Niklas Cassel)
- Align the nr_irqs parameter encoding for
pci_epc_set_msi()/pci_epc_ops::set_msi() and
pci_epc_set_msix()/pci_epc_ops::set_msix() (Niklas Cassel)
Common host controller library:
- Convert pci-host-common to a library so platforms that don't need
native host controller drivers don't need to include these helper
functions (Manivannan Sadhasivam)
Apple PCIe controller driver:
- Extract ECAM bridge creation helper from pci_host_common_probe() to
separate driver-specific things like MSI from PCI things (Marc
Zyngier)
- Dynamically allocate RID-to_SID bitmap to prepare for SoCs with
varying capabilities (Marc Zyngier)
- Skip ports disabled in DT when setting up ports (Janne Grunau)
- Add t6020 compatible string (Alyssa Rosenzweig)
- Add T602x PCIe support (Hector Martin)
- Directly set/clear INTx mask bits because T602x dropped the
accessors that could do this without locking (Marc Zyngier)
- Move port PHY registers to their own reg items to accommodate
T602x, which moves them around; retain default offsets for existing
DTs that lack phy%d entries with the reg offsets (Hector Martin)
- Stop polling for core refclk, which doesn't work on T602x and the
bootloader has already done anyway (Hector Martin)
- Use gpiod_set_value_cansleep() when asserting PERST# in probe
because we're allowed to sleep there (Hector Martin)
Cadence PCIe controller driver:
- Drop a runtime PM 'put' to resolve a runtime atomic count underflow
(Hans Zhang)
- Make the cadence core buildable as a module (Kishon Vijay Abraham I)
- Add cdns_pcie_host_disable() and cdns_pcie_ep_disable() for use by
loadable drivers when they are removed (Siddharth Vadapalli)
Freescale i.MX6 PCIe controller driver:
- Apply link training workaround only on IMX6Q, IMX6SX, IMX6SP
(Richard Zhu)
- Remove redundant dw_pcie_wait_for_link() from
imx_pcie_start_link(); since the DWC core does this, imx6 only
needs it when retraining for a faster link speed (Richard Zhu)
- Toggle i.MX95 core reset to align with PHY powerup (Richard Zhu)
- Set SYS_AUX_PWR_DET to work around i.MX95 ERR051624 erratum: in
some cases, the controller can't exit 'L23 Ready' through Beacon or
PERST# deassertion (Richard Zhu)
- Clear GEN3_ZRXDC_NONCOMPL to work around i.MX95 ERR051586 erratum:
controller can't meet 2.5 GT/s ZRX-DC timing when operating at 8
GT/s, causing timeouts in L1 (Richard Zhu)
- Wait for i.MX95 PLL lock before enabling controller (Richard Zhu)
- Save/restore i.MX95 LUT for suspend/resume (Richard Zhu)
Mobiveil PCIe controller driver:
- Return bool (not int) for link-up check in
mobiveil_pab_ops.link_up() and layerscape-gen4, mobiveil (Hans
Zhang)
NVIDIA Tegra194 PCIe controller driver:
- Create debugfs directory for 'aspm_state_cnt' only when
CONFIG_PCIEASPM is enabled, since there are no other entries (Hans
Zhang)
Qualcomm PCIe controller driver:
- Add OF support for parsing DT 'eq-presets-<N>gts' property for lane
equalization presets (Krishna Chaitanya Chundru)
- Read Maximum Link Width from the Link Capabilities register if DT
lacks 'num-lanes' property (Krishna Chaitanya Chundru)
- Add Physical Layer 64 GT/s Capability ID and register offsets for
8, 32, and 64 GT/s lane equalization registers (Krishna Chaitanya
Chundru)
- Add generic dwc support for configuring lane equalization presets
(Krishna Chaitanya Chundru)
- Add DT and driver support for PCIe on IPQ5018 SoC (Nitheesh Sekar)
Renesas R-Car PCIe controller driver:
- Describe endpoint BAR 4 as being fixed size (Jerome Brunet)
- Document how to obtain R-Car V4H (r8a779g0) controller firmware
(Yoshihiro Shimoda)
Rockchip PCIe controller driver:
- Reorder rockchip_pci_core_rsts because
reset_control_bulk_deassert() deasserts in reverse order, to fix a
link training regression (Jensen Huang)
- Mark RK3399 as being capable of raising INTx interrupts (Niklas
Cassel)
Rockchip DesignWare PCIe controller driver:
- Check only PCIE_LINKUP, not LTSSM status, to determine whether the
link is up (Shawn Lin)
- Increase N_FTS (used in L0s->L0 transitions) and enable ASPM L0s
for Root Complex and Endpoint modes (Shawn Lin)
- Hide the broken ATS Capability in rockchip_pcie_ep_init() instead
of rockchip_pcie_ep_pre_init() so it stays hidden after PERST#
resets non-sticky registers (Shawn Lin)
- Call phy_power_off() before phy_exit() in rockchip_pcie_phy_deinit()
(Diederik de Haas)

- Set PORT_LOGIC_LINK_WIDTH to one lane to make initial link training
more robust; this will not affect the intended link width if all
lanes are functional (Wenbin Yao)
- Return bool (not int) for link-up check in dw_pcie_ops.link_up()
and armada8k, dra7xx, dw-rockchip, exynos, histb, keembay,
keystone, kirin, meson, qcom, qcom-ep, rcar_gen4, spear13xx,
tegra194, uniphier, visconti (Hans Zhang)

- Make j721e buildable as a loadable and removable module (Siddharth
Vadapalli)
- Fix j721e host/endpoint dependencies that result in link failures
in some configs (Arnd Bergmann)
Device tree bindings:

link-specific events) for ipq8074, ipq8074-gen3, ipq6018, sa8775p,
sc7280, sc8180x sdm845, sm8150, sm8250, sm8350 (Manivannan
