It turns out that the change in commit 76934e495c ("cpuidle: Add
sanity check for exit latency and target residency") goes too far
because there are systems in the field on which the check introduced
by that commit does not pass.
For this reason, change __cpuidle_driver_init() return type back to void
and make it print a warning when the check mentioned above does not
pass.

Some device drivers (and out-of-tree modules) might want to define
device-specific device governors. Rather than restricting all of them to
be a part of drivers/devfreq/ (which is not possible for out-of-tree
drivers anyway) move governor.h to include/linux/devfreq-governor.h and
update all drivers to use it.
The devfreq_cpu_data is only used internally, by the passive governor,
so it is moved to the driver source rather than being a part of the
public interface.

There is a race condition between timer_shutdown_sync() and timer
expiration that can lead to hitting a WARN_ON in expire_timers().
The issue occurs when timer_shutdown_sync() clears the timer function
to NULL while the timer is still running on another CPU. The race
scenario looks like this:
CPU0 CPU1
<SOFTIRQ>
lock_timer_base()
expire_timers()
base->running_timer = timer;
unlock_timer_base()
[call_timer_fn enter]
mod_timer()
...
timer_shutdown_sync()
lock_timer_base()
// For now, will not detach the timer but only clear its function to NULL
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
[call_timer_fn exit]
lock_timer_base()
base->running_timer = NULL;
unlock_timer_base()
...
// Now timer is pending while its function set to NULL.
// next timer trigger
<SOFTIRQ>
expire_timers()
WARN_ON_ONCE(!fn) // hit
...
lock_timer_base()
// Now timer will detach
if (base->running_timer != timer)
ret = detach_if_pending(timer, base, true);
if (shutdown)
timer->function = NULL;
unlock_timer_base()
The problem is that timer_shutdown_sync() clears the timer function
regardless of whether the timer is currently running. This can leave a
pending timer with a NULL function pointer, which triggers the
WARN_ON_ONCE(!fn) check in expire_timers().
Fix this by only clearing the timer function when actually detaching the
timer. If the timer is running, leave the function pointer intact, which is
safe because the timer will be properly detached when it finishes running.

Merge tag 'selinux-pr-20251121' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux
Pull selinux fixes from Paul Moore:
"Three SELinux patches for v6.18 to fix issues around accessing the
per-task decision cache that we introduced in v6.16 to help reduce
SELinux overhead on path walks. The problem was that despite the cache
being located in the SELinux "task_security_struct", the parent struct
wasn't actually tied to the task, it was tied to a cred.
Historically SELinux did locate the task_security_struct in the
task_struct's security blob, but it was later relocated to the cred
struct when the cred work happened, as it made the most sense at the
time.
Unfortunately we never did the task_security_struct to
cred_security_struct rename work (avoid code churn maybe? who knows)
because it didn't really matter at the time. However, it suddenly
became a problem when we added a per-task cache to a per-cred object
and didn't notice because of the old, no-longer-correct struct naming.
Thanks to KCSAN for flagging this, as the silly humans running things
forgot that the task_security_struct was a big lie.
This contains three patches, only one of which actually fixes the
problem described above and moves the SELinux decision cache from the
per-cred struct to a newly (re)created per-task struct.
The other two patches, which form the bulk of the diffstat, take care
of the associated renaming tasks so we can hopefully avoid making the
same stupid mistake in the future.
For the record, I did contemplate sending just a fix for the cache,
leaving the renaming patches for the upcoming merge window, but the
type/variable naming ended up being pretty awful and would have made
v6.18 an outlier stuck between the "old" names and the "new" names in
v6.19. The renaming patches are also fairly mechanical/trivial and
shouldn't pose much risk despite their size.
TLDR; naming things may be hard, but if you mess it up bad things
happen"

Currently, RAPL PMU support requires adding CPU model entries to
arch/x86/events/rapl.c for each new generation. However, RAPL MSRs are
not architectural and require platform-specific customization, making
arch/x86 an inappropriate location for this functionality.
The powercap subsystem already handles RAPL functionality and is the
natural place to consolidate all RAPL features. The powercap RAPL
driver already includes PMU support for TPMI-based RAPL interfaces,
making it straightforward to extend this support to MSR-based RAPL
interfaces as well.
This consolidation eliminates the need to maintain RAPL support in
multiple subsystems and provides a unified approach for both TPMI and
MSR-based RAPL implementations.
The MSR-based PMU support includes the following updates:
1. Register MSR-based PMU support for the supported platforms
and unregister it when no online CPUs remain in the package.
2. Remove existing checks that restrict RAPL PMU support to TPMI-based
interfaces and extend the logic to allow MSR-based RAPL interfaces.
3. Define a CPU model list to determine which processors should
register RAPL PMU interface through the powercap driver for
MSR-based RAPL, excluding those that support TPMI interface.
This list prevents conflicts with existing arch/x86 PMU code
that already registers RAPL PMU for some processors. Add
Panther Lake & Wildcat Lake to the CPU models list.

The current read_raw() implementation of the TPMI, MMIO and MSR
interfaces does not distinguish between atomic and non-atomic callers.
rapl_msr_read_raw() uses rdmsrq_safe_on_cpu(), which can sleep and
issue cross CPU calls. When MSR-based RAPL PMU support is enabled, PMU
event handlers can invoke this function from atomic context where
sleeping or rescheduling is not allowed. In atomic context, the caller
is already executing on the target CPU, so a direct rdmsrq() is
sufficient.
To support such usage, introduce an atomic flag to the read_raw()
interface to allow callers pass the context information. Modify the
common RAPL code to propagate this flag, and set the flag to reflect
the calling contexts.
Utilize the atomic flag in rapl_msr_read_raw() to perform direct MSR
read with rdmsrq() when running in atomic context, and a sanity check
to ensure target CPU matches the current CPU for such use cases.
The TPMI and MMIO implementations do not require special atomic
handling, so the flag is ignored in those paths.
This is a preparatory patch for adding MSR-based RAPL PMU support.

Apparently as of version 2.42, glibc headers define AT_RENAME_NOREPLACE
and some of the other flags for renameat2() and friends in <stdio.h>.
Which would all be fine, except for inexplicable reasons glibc decided
to define them _differently_ from the kernel definitions, which then
makes some of our sample code that includes both kernel headers and user
space headers unhappy, because the compiler will (correctly) complain
about redefining things.
Now, mixing kernel headers and user space headers is always a somewhat
iffy proposition due to namespacing issues, but it's kind of inevitable
in our sample and selftest code. And this is just glibc being stupid.
Those defines come from the kernel, glibc is exposing the kernel
interfaces, and glibc shouldn't make up some random new expressions for
these values.
It's not like glibc headers changed the actual result values, but they
arbitrarily just decided to use a different expression to describe those
values. The kernel just does
#define AT_RENAME_NOREPLACE 0x0001
while glibc does
# define RENAME_NOREPLACE (1 << 0)
# define AT_RENAME_NOREPLACE RENAME_NOREPLACE
instead. Same value in the end, but very different macro definition.
For absolutely no reason.
This has since been fixed in the glibc development tree, so eventually
we'll end up with the canonical expressions and no clashes. But in the
meantime the broken headers are in the glibc-2.42 release and have made
it out into distributions.
Do a minimal work-around to make the samples build cleanly by just
undefining the affected macros in between the user space header include
and the kernel header includes.

Commit 69896119dc ("MIPS: vdso: Switch to generic storage
implementation") switches to a generic vdso storage, which increases
the number of data pages from 1 to 4. But there is only one page
reserved, which causes segementation faults depending where the VDSO
area is randomized to. To fix this use the same size of reservation
and allocation of the VDSO data pages.

Depending on the particular CPU implementation a TLB shutdown may occur
if multiple matching entries are detected upon the execution of a TLBP
or the TLBWI/TLBWR instructions. Given that we don't know what entries
we have been handed we need to be very careful with the initial TLB
setup and avoid all these instructions.
Therefore read all the TLB entries one by one with the TLBR instruction,
bypassing the content addressing logic, and truncate any large pages in
place so as to avoid a case in the second step where an incoming entry
for a large page at a lower address overlaps with a replacement entry
chosen at another index. Then preinitialize the TLB using addresses
outside our usual unique range and avoiding clashes with any entries
received, before making the usual call to local_flush_tlb_all().
This fixes (at least) R4x00 cores if TLBP hits multiple matching TLB
entries (SGI IP22 PROM for examples sets up all TLBs to the same virtual
address).

If CONFIG_OF is not enabled, of_match_node() is set as NULL and
qcom_cpufreq_ipq806x_match_list won't be used causing a compilation
warning.
Flag qcom_cpufreq_ipq806x_match_list as __maybe_unused to fix the
compilation warning.
While at it also flag as __initconst as it's used only in probe contest
and can be freed after probe.
This follows the pattern of the usual of_device_id variables.

Along with the renaming from task_security_struct to cred_security_struct,
rename the local variables to "crsec" from "tsec". This both fits with
existing conventions and helps distinguish between task and cred related
variables.

Before Linux had cred structures, the SELinux task_security_struct was
per-task and although the structure was switched to being per-cred
long ago, the name was never updated. This change renames it to
cred_security_struct to avoid confusion and pave the way for the
introduction of an actual per-task security structure for SELinux. No

Replace the direct calls to ksys_sync_helper() with the new
pm_sleep_fs_sync() in suspend and hibernation code paths.
This enables the new mechanism allowing the filesystem sync phase

Add helper function pm_sleep_fs_sync() and related data structures
as a preparation for allowing system suspend and hibernation to be
aborted by wakeup events while syncing file systems.
The new function, to be called by the suspend process in order to
sync file systems, uses a dedicated ordered workqueue to run
ksys_sync_helper() in parallel with the calling process. Next, it
waits for the completion of the filesystem sync and periodically
checks if any system wakeup events are pending, in which case it will
return an error.
If that happens while the filesystem sync is still in progress, it
will continue, possibly after pm_sleep_fs_sync() has returned, and if
that function is called again before the sync is complete, a new work
item to run ksys_sync_helper() again will be queued (and waited for)
to increase the likelihood of writing all of the dirty pages in memory
back to persistent storage.
