- Unrelated x86/cc changes queued here to avoid ugly cross-merges and
conflicts:
- Carve out CPU hotplug function declarations into a separate header
with the goal to be able to use the lockdep assertions in a more
flexible manner
- As a result, refactor cacheinfo code after carving out a function
to return the cache ID associated with a given cache level
- Cleanups
- Add support to be able to kexec TDX guests. For that
- Expand ACPI MADT CPU offlining support
- Add machinery to prepare CoCo guests memory before kexec-ing into a new
kernel
- Cleanup, readjust and massage related code

spi: Updates for v6.11
There's some quite exciting core work in this release, we've got the
beginnings of support for hardware initiated transfers which is itself
independently useful for optimising fast paths in existing drivers.
We also have a rework of the DMA mapping which allows finer grained
decisions about DMA mapping messages and also helps remove some bodges
that we'd had.
Otherwise it's a fairly quiet release, a few new drivers and features
for existing drivers, together with various cleanups and DT binding
conversions.
One regmap SPI fix made it's way in here too which I should probably
have sent as a regmap fix instead.
- Support for pre-optimising messages, reducing the overhead for
messages that are repeatedly used (eg, reading the interrupt status
from a device). This will also be used for hardware initiated
transfers in future.
- A reworking of how DMA mapping is done, introducing a new helper and
allowing the DMA mapping decision to be done per transfer instead of
per message.
- Support for Atmel SAMA7D64, Freescale LX2160A DSPI and WCH CH341A.

regulator: Updates for v6.11
This s a very quiet release for the regulator API, we have a few new
devices (most of which are just ID updates) and one new fairly
specialist core feature for use in interrupt context.
- An API allowing lockless enable/disable for regulators acquired in
exclusive mode, for use in interrupt contexts.
- A rewrite of the MedaTek DVFSRC regulator driver which apparently
never worked.
- Support for Mediaktek MT6312, Qualcomm QCA6390 and WCN7850, Renesas
RZ/G2L USB VBUS regulator and ST Microelectronics STM32MP13.

regmap: Updates for v6.11
There's one new feature here, a regmap_multi_reg_read() matching the existing write function which has some IIO users coming. This allows atomic reads from multiple registers without the need to wrap a higher level lock in the client driver just for regmap (which already has locks anyway). We also have one fix for the KUnit tests, and a bunch of cleanups. -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmaVJRsACgkQJNaLcl1U h9CQcAf+PhHwUoxBextaJzy2HQe9CFV71/I4GEj0MTrtpqKDhmO8AQnsI4dKXr/9 hZPUPR7+6qw7N12NdZQcT6hIX9CnhdiaNALo4ANvG5KlxFljhFbv2sBg1QAgb+Ks 2gLapB4HY0jso+6urNEN5rvucFpf4Mxlz5ilrk3kuuJaC/xf6/QXoU5/9PjPyD5s ZuCBMg5G0BIIdwc9SFGJPv1UUJ0H6Aj/1ZQNo/JVtIj8uGt8TuvnUrmOxdnHRN1U b5AMjLnSYMtwRg7Nd/DCINmwPN+I0X79gNE4SG1LAOlQIChhW+47HuGWyCM40jGO p4X8o/zID9hw5q3y6CpwYvrJ5GRZbA== =ETId -----END PGP SIGNATURE----- Merge tag 'regmap-v6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "There's one new feature here, a regmap_multi_reg_read() matching the existing write function which has some IIO users coming.

gpio updates for v6.11-rc1
GPIOLIB core:
- rework kfifo handling rework in the character device code
- improve the labeling of GPIOs requested as interrupts and show more info
on interrupt-only GPIOs in debugfs
- remove unused APIs
- unexport interfaces that are only used from the core GPIO code
- drop the return value from gpiochip_set_desc_names() as it cannot fail
- move a string array definition out of a header and into a specific
compilation unit
- convert the last user of gpiochip_get_desc() other than GPIO core to using
a safer alternative
- use array_index_nospec() where applicable
New drivers:
- add a "virtual GPIO consumer" module that allows requesting GPIOs from actual
hardware and driving tests of the in-kernel GPIO API from user-space over
debugfs
- add a GPIO-based "sloppy" logic analyzer module useful for "first glance"
debugging on remote boards
Driver improvements:
- add support for a new model to gpio-pca953x
- lock GPIOs as interrupts in gpio-sim when the lines are requested as irqs
via the simulator domain + some other minor improvements
- improve error reporting in gpio-syscon
- convert gpio-ath79 to using dynamic GPIO base and range
- use pcibios_err_to_errno() for converting PCIBIOS error codes to errno
vaues in gpio-amd8111 and gpio-rdc321x
- allow building gpio-brcmstb for the BCM2835 architecture
DT bindings:
- convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
- document new properties for aspeed,gpio, fsl,qoriq-gpio and gpio-vf610
- document new compatibles for pca953x and fsl,qoriq-gpio
Documentation:
- document stricter behavior of the GPIO character device uAPI with regards to
reconfiguring requested line without direction set
- clarify the effect of the active-low flag on line values and edges
- remove documentation for the legacy GPIO API in order to stop tempting
people to use it
- document the preference for using pread() for reading edge events in the
sysfs API
Other:
- add an extended initializer to the interrupt simulator allowing to specify
a number of callbacks callers can use to be notified about irqs being
requested and released

pwm: Changes for v6.11-rc1
This contains the usual mix of fixes, cleanups, two new drivers and several dt binding updates. The fixes are for minor issues that are already old (4.11-rc1 and 3.9-rc1) and were found by code review and not during usage, so I didn't sent them for earlier inclusion. The changes to include/linux/mfd/stm32-timers.h and drivers/counter/stm32-timer-cnt.c are part of an immutable branch that will also be included in the mfd and counter PR. It changes some register definitions and affects the pwm-stm32 driver.

The main problem we're fixing is powering up devices which are represented as separate objects in the kernel (binding to different drivers) but which share parts of the power-up sequence and thus need some kind of a mediator who knows the possible interactions and can assure they don't interfere with neither device's bring up. An example of such an inter-driver interaction is the WCN family of BT/WLAN chips from Qualcomm of which some models require the user to observe a certain delay between driving the bt-enable and wlan-enable GPIOs. This is not a new problem but up to this point all attempts at addressing it ended up hitting one wall or another and being dropped. The main obstacle was the fact that most these attempts tried to introduce the concept of a "power sequence" into the device-tree bindings which breaks the main DT rule: describe the hardware, not its behavior. The solution I proposed focuses on making the power sequencer drivers interpret the actual HW description flexibly. More details on that are in the linked cover letter. The second problem fixed here is powering up PCI devices before they are detected on the bus. This is achieved by creating special platform devices for device-tree nodes describing hard-wired PCI devices which bind to the so-called PCI power control drivers which enable required resources and trigger a bus rescan once the controlled device is up then setup the correct devlink hierarchy for power-management. By combining the two new frameworks we implemented the power sequencing PCI power control driver which is capable of powering up the WLAN modules of the QCom WCN family of chipsets. All this has spent a significant amount of time in linux-next and enabled WLAN/BT support on several Qualcomm platforms. To further prove that this is useful and needed: right after this was picked up into next, I was sent a series using the subsystem for a similar use-case on Amlogic platforms. This contains the core power sequencing framework, the first driver, PCI changes using the pwrseq library (blessed by Bjorn Helgaas) and some fixes that came later" * tag 'pwrseq-updates-for-v6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: PCI/pwrctl: only call of_platform_populate() if CONFIG_OF is enabled power: sequencing: simplify returning pointer without cleanup PCI/pwrctl: Add a PCI power control driver for power sequenced devices PCI/pwrctl: Add PCI power control core code PCI/pwrctl: Create platform devices for child OF nodes of the port node PCI/pwrctl: Reuse the OF node for power controlled devices PCI: Hold the rescan mutex when scanning for the first time power: pwrseq: add a driver for the PMU module on the QCom WCN chipsets power: sequencing: implement the pwrseq core |

arm64 updates for 6.11:
* Virtual CPU hotplug support for arm64 ACPI systems
* cpufeature infrastructure cleanups and making the FEAT_ECBHB ID bits
visible to guests
* CPU errata: expand the speculative SSBS workaround to more CPUs
* arm64 ACPI:
- acpi=nospcr option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
* GICv3, use compile-time PMR values: optimise the way regular IRQs are
masked/unmasked when GICv3 pseudo-NMIs are used, removing the need for
a static key in fast paths by using a priority value chosen
dynamically at boot time
* arm64 perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed

Merge tag 'arm64-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 updates from Catalin Marinas:
"The biggest part is the virtual CPU hotplug that touches ACPI,
irqchip. We also have some GICv3 optimisation for pseudo-NMIs that has
been queued via the arm64 tree. Otherwise the usual perf updates,
kselftest, various small cleanups.
Core:
- Virtual CPU hotplug support for arm64 ACPI systems
- cpufeature infrastructure cleanups and making the FEAT_ECBHB ID
bits visible to guests
- CPU errata: expand the speculative SSBS workaround to more CPUs
- GICv3, use compile-time PMR values: optimise the way regular IRQs
are masked/unmasked when GICv3 pseudo-NMIs are used, removing the
need for a static key in fast paths by using a priority value
chosen dynamically at boot time
ACPI:
- 'acpi=nospcr' option to disable SPCR as default console for arm64
- Move some ACPI code (cpuidle, FFH) to drivers/acpi/arm64/
Perf updates:
- Rework of the IMX PMU driver to enable support for I.MX95
- Enable support for tertiary match groups in the CMN PMU driver
- Initial refactoring of the CPU PMU code to prepare for the fixed
instruction counter introduced by Arm v9.4
- Add missing PMU driver MODULE_DESCRIPTION() strings
- Hook up DT compatibles for recent CPU PMUs
Kselftest updates:
- Kernel mode NEON fp-stress
- Cleanups, spelling mistakes
Miscellaneous:
- arm64 Documentation update with a minor clarification on TBI
- Fix missing IPI statistics
- Implement raw_smp_processor_id() using thread_info rather than a
per-CPU variable (better code generation)
- Make MTE checking of in-kernel asynchronous tag faults conditional

Updates for timers, timekeeping and related functionality:
- Core:
- Make the takeover of a hrtimer based broadcast timer reliable during
CPU hot-unplug. The current implementation suffers from a race which
can lead to broadcast timer starvation in the worst case.
- VDSO related cleanups and simplifications
- Small cleanups and enhancements all over the place
- PTP:
- Replace the architecture specific base clock to clocksource, e.g. ART
to TSC, conversion function with generic functionality to avoid
exposing such internals to drivers and convert all existing drivers
over. This also allows to provide functionality which converts the
other way round in the core code based on the same parameter set.
- Provide a function to convert CLOCK_REALTIME to the base clock to
support the upcoming PPS output driver on Intel platforms.
- Drivers:
- A set of Device Tree bindings for new hardware
- Cleanups and enhancements all over the place

A small set of SMP/CPU hotplug updates:
- Reverse the order of iteration when freezing secondary CPUs for
hibernation.
This avoids that drivers like the Intel uncore performance counter have
to transfer the assignement of handling the per package uncore events
for every CPU in a package, which is a considerable speedup on larger
systems.
- Add a missing destroy_work_on_stack() invocation in smp_call_on_cpu()
to prevent debug objects to emit a false positive warning when the
stack is freed.
- Small cleanups in comments and a str_plural() conversion

The motivating use-case comes from LXCFS which is a tiny fuse filesystem used to virtualize various aspects of procfs. LXCFS is run on the host. The files and directories it creates can be bind-mounted by e.g. a container at startup and mounted over the various procfs files the container wishes to have virtualized. When e.g. a read request for uptime is received, LXCFS will receive the pid of the reader. In order to virtualize the corresponding read, LXCFS needs to know the pid of the init process of the reader's pid namespace. In order to do this, LXCFS first needs to fork() two helper processes. The first helper process setns() to the readers pid namespace. The second helper process is needed to create a process that is a proper member of the pid namespace. The second helper process then creates a ucred message with ucred.pid set to 1 and sends it back to LXCFS. The kernel will translate the ucred.pid field to the corresponding pid number in LXCFS's pid namespace. This way LXCFS can learn the init pid number of the reader's pid namespace and can go on to virtualize. Since these two forks() are costly LXCFS maintains an init pid cache that caches a given pid for a fixed amount of time. The cache is pruned during new read requests. However, even with the cache the hit of the two forks() is singificant when a very large number of containers are running. So this adds a simple set of ioctls that let's a caller translate PIDs from and into a given PID namespace. This significantly improves performance with a very simple change. To protect against races pidfds can be used to check whether the process is still valid" * tag 'vfs-6.11.nsfs' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: nsfs: add pid translation ioctls |

Merge tag 'vfs-6.11.mount' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs
Pull vfs mount query updates from Christian Brauner:
"This contains work to extend the abilities of listmount() and
statmount() and various fixes and cleanups.
Features:
- Allow iterating through mounts via listmount() from newest to
oldest. This makes it possible for mount(8) to keep iterating the
mount table in reverse order so it gets newest mounts first.
- Relax permissions on listmount() and statmount().
It's not necessary to have capabilities in the initial namespace:
it is sufficient to have capabilities in the owning namespace of
the mount namespace we're located in to list unreachable mounts in
that namespace.
- Extend both listmount() and statmount() to list and stat mounts in
foreign mount namespaces.
Currently the only way to iterate over mount entries in mount
namespaces that aren't in the caller's mount namespace is by
crawling through /proc in order to find /proc/<pid>/mountinfo for
the relevant mount namespace.
This is both very clumsy and hugely inefficient. So extend struct
mnt_id_req with a new member that allows to specify the mount
namespace id of the mount namespace we want to look at.
Luckily internally we already have most of the infrastructure for
this so we just need to expose it to userspace. Give userspace a
way to retrieve the id of a mount namespace via statmount() and
through a new nsfs ioctl() on mount namespace file descriptor.
This comes with appropriate selftests.
- Expose mount options through statmount().
Currently if userspace wants to get mount options for a mount and
with statmount(), they still have to open /proc/<pid>/mountinfo to
parse mount options. Simply the information through statmount()
directly.
Afterwards it's possible to only rely on statmount() and
listmount() to retrieve all and more information than
/proc/<pid>/mountinfo provides.
This comes with appropriate selftests.
Fixes:
- Avoid copying to userspace under the namespace semaphore in
listmount.
Cleanups:
- Simplify the error handling in listmount by relying on our newly
added cleanup infrastructure.
- Refuse invalid mount ids early for both listmount and statmount"

Pull vfs inode / dentry updates from Christian Brauner:
"This contains smaller performance improvements to inodes and dentries:
inode:
- Add rcu based inode lookup variants.
They avoid one inode hash lock acquire in the common case thereby
significantly reducing contention. We already support RCU-based
operations but didn't take advantage of them during inode
insertion.
Callers of iget_locked() get the improvement without any code
changes. Callers that need a custom callback can switch to
iget5_locked_rcu() as e.g., did btrfs.
With 20 threads each walking a dedicated 1000 dirs * 1000 files
directory tree to stat(2) on a 32 core + 24GB ram vm:
before: 3.54s user 892.30s system 1966% cpu 45.549 total
after: 3.28s user 738.66s system 1955% cpu 37.932 total (-16.7%)
Long-term we should pick up the effort to introduce more
fine-grained locking and possibly improve on the currently used
hash implementation.
- Start zeroing i_state in inode_init_always() instead of doing it in
individual filesystems.
This allows us to remove an unneeded lock acquire in new_inode()
and not burden individual filesystems with this.
dcache:
- Move d_lockref out of the area used by RCU lookup to avoid
cacheline ping poing because the embedded name is sharing a
cacheline with d_lockref.
- Fix dentry size on 32bit with CONFIG_SMP=y so it does actually end
up with 128 bytes in total"

for fetching the pathname from user space) is very hot.
This is a very specialized "instruction alternatives" model where the
dentry hash pointer and hash count will be constants for the lifetime of
the kernel, but the allocation are not static but done early during the
kernel boot. In order to avoid the pointer load and dynamic shift, we
just rewrite the constants in the instructions in place.
We can't use the "generic" alternative instructions infrastructure,
because different architectures do it very differently, and it's
actually simpler to just have very specific helpers, with a fallback to
the generic ("old") model of just using variables for architectures that
do not implement the runtime constant patching infrastructure.

arm64: add 'runtime constant' support
runtime constants: add x86 architecture support
runtime constants: add default dummy infrastructure

Pull btrfs fixes from David Sterba:
"Fix a regression in extent map shrinker behaviour.
In the past weeks we got reports from users that there are huge
latency spikes or freezes. This was bisected to newly added shrinker
of extent maps (it was added to fix a build up of the structures in
memory).
I'm assuming that the freezes would happen to many users after release
so I'd like to get it merged now so it's in 6.10. Although the diff
size is not small the changes are relatively straightforward, the
reporters verified the fixes and we did testing on our side.
The fixes:
- adjust behaviour under memory pressure and check lock or scheduling
conditions, bail out if needed
- synchronize tracking of the scanning progress so inode ranges are
not skipped or work duplicated
- do a delayed iput when scanning a root so evicting an inode does
not slow things down in case of lots of dirty data, also fix
lockdep warning, a deadlock could happen when writing the dirty
data would need to start a transaction"

cgroup/misc: Introduce misc.events.local
Currently the event counting provided by misc.events is hierarchical, it's not practical if user is only concerned with events of a specified cgroup. Therefore, introduce misc.events.local collect events specific to the given cgroup. This is analogous to memory.events.local and pids.events.local.

spi: Fixes for v6.10
This pull request fixes two regressions that have been bubbling along
for a large part of this release. One is a revert of the multi mode
support for the OMAP SPI controller, this introduced regressions on a
number of systems and while there has been progress on fixing those
we've not got something that works for everyone yet so let's just drop
the change for now. The other is a series of fixes from David Lechner
for his recent message optimisation work, this interacted badly with
spi-mux which is altogether too clever with recursive use of the bus and
creates situations that hadn't been considered.
There are also a couple of small driver specific fixes, including one
more patch from David for sleep duration calculations in the AXI driver.

"cachefiles:
- Export an existing and add a new cachefile helper to be used in
filesystems to fix reference count bugs
- Use the newly added fscache_ty_get_volume() helper to get a
reference count on an fscache_volume to handle volumes that are
about to be removed cleanly
- After withdrawing a fscache_cache via FSCACHE_CACHE_IS_WITHDRAWN
wait for all ongoing cookie lookups to complete and for the object
count to reach zero
- Propagate errors from vfs_getxattr() to avoid an infinite loop in
cachefiles_check_volume_xattr() because it keeps seeing ESTALE
- Don't send new requests when an object is dropped by raising
CACHEFILES_ONDEMAND_OJBSTATE_DROPPING
- Cancel all requests for an object that is about to be dropped
- Wait for the ondemand_boject_worker to finish before dropping a
cachefiles object to prevent use-after-free
- Use cyclic allocation for message ids to better handle id recycling
- Add missing lock protection when iterating through the xarray when
polling
netfs:
- Use standard logging helpers for debug logging
VFS:
- Fix potential use-after-free in file locks during
trace_posix_lock_inode(). The tracepoint could fire while another
task raced it and freed the lock that was requested to be traced
- Only increment the nr_dentry_negative counter for dentries that are
present on the superblock LRU. Currently, DCACHE_LRU_LIST list is
used to detect this case. However, the flag is also raised in
combination with DCACHE_SHRINK_LIST to indicate that dentry->d_lru
is used. So checking only DCACHE_LRU_LIST will lead to wrong
nr_dentry_negative count. Fix the check to not count dentries that
are on a shrink related list

drm/xe: Use write-back caching mode for system memory on DGFX
The caching mode for buffer objects with VRAM as a possible placement was forced to write-combined, regardless of placement. However, write-combined system memory is expensive to allocate and even though it is pooled, the pool is expensive to shrink, since it involves global CPU TLB flushes. Moreover write-combined system memory from TTM is only reliably available on x86 and DGFX doesn't have an x86 restriction. So regardless of the cpu caching mode selected for a bo, internally use write-back caching mode for system memory on DGFX. Coherency is maintained, but user-space clients may perceive a difference in cpu access speeds. v2: - Update RB- and Ack tags. - Rephrase wording in xe_drm.h (Matt Roper) v3: - Really rephrase wording.

btrfs: avoid races when tracking progress for extent map shrinking
We store the progress (root and inode numbers) of the extent map shrinker in fs_info without any synchronization but we can have multiple tasks calling into the shrinker during memory allocations when there's enough memory pressure for example. This can result in a task A reading fs_info->extent_map_shrinker_last_ino after another task B updates it, and task A reading fs_info->extent_map_shrinker_last_root before task B updates it, making task A see an odd state that isn't necessarily harmful but may make it skip certain inode ranges or do more work than necessary by going over the same inodes again. These unprotected accesses would also trigger warnings from tools like KCSAN. So add a lock to protect access to these progress fields.

regmap: Implement regmap_multi_reg_read()
Merge series from Guenter Roeck <linux@roeck-us.net>: regmap_multi_reg_read() is similar to regmap_bilk_read() but reads from an array of non-sequential registers. It is helpful if multiple non- sequential registers need to be read in a single operation which would otherwise have to be mutex protected. The name of the new function was chosen to match the existing function regmap_multi_reg_write(). |
