0cc9841670 i2c: xiic: Use devm_platform_get_and_ioremap_resource()
According to commit 890cc39a87 ("drivers: provide
devm_platform_get_and_ioremap_resource()"), convert
platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

12ca59b91d clk: Print an info line before disabling unused clocks
Currently, the regulator framework informs us before calling into
their unused cleanup paths, which eases at least some debugging. The
same could be beneficial for clocks, so that random shutdowns shortly
after most initcalls are done can be less of a guess.

Add a pr_info before disabling unused clocks to do so.

RISC-V: always select RISCV_ALTERNATIVE for non-xip kernels
When moving switch_to's has_fpu() over to using
riscv_has_extension_likely() rather than static branches, the FPU code
gained a dependency on the alternatives framework.
That dependency has now been removed, as riscv_has_extension_ikely() now
contains a fallback path, using __riscv_isa_extension_available(), but
if CONFIG_RISCV_ALTERNATIVE isn't selected when CONFIG_FPU is, has_fpu()
checks will not benefit from the "fast path" that the alternatives
framework provides.

We want to ensure that alternatives are available whenever
riscv_has_extension_[un]likely() is used, rather than silently falling
back to the slow path, but rather than rely on selecting
RISCV_ALTERNATIVE in the myriad of locations that may use
riscv_has_extension_[un]likely(), select it (almost) always instead by
adding it to the main RISCV config entry.
xip kernels cannot make use of the alternatives framework, so it is not
enabled for those configurations, although this is the status quo.

All current sites that select RISCV_ALTERNATIVE are converted to
dependencies on the option instead. The explicit dependencies on
!XIP_KERNEL can be dropped, as RISCV_ALTERNATIVE is not user selectable.

RISC-V: add non-alternative fallback for riscv_has_extension_[un]likely()
The has_fpu() check, which in turn calls riscv_has_extension_likely(),
relies on alternatives to figure out whether the system has an FPU.
As a result, it will malfunction on XIP kernels, as they do not support
the alternatives mechanism.

When alternatives support is not present, fall back to using
__riscv_isa_extension_available() in riscv_has_extension_[un]likely()
instead stead, which handily takes the same argument, so that kernels
that do not support alternatives can accurately report the presence of
FPU support.

1bf33285d9 cgroup/cpuset: Minor updates to test_cpuset_prs.sh
This patch makes the following minor updates to the cpuset partition
testing script test_cpuset_prs.sh.

 - Remove online_cpus function call as it will be called anyway on exit
   in cleanup.
 - Make the enabling of sched/verbose debugfs flag conditional on the
   "-v" verbose option and set DELAY_FACTOR to 2 in this case as cpuset
   partition operations are likely to be slowed down by enabling that.

292fd843de cgroup/cpuset: Fix partition root's cpuset.cpus update bug
It was found that commit 7a2127e66a ("cpuset: Call
set_cpus_allowed_ptr() with appropriate mask for task") introduced a bug
that corrupted "cpuset.cpus" of a partition root when it was updated.

It is because the tmp->new_cpus field of the passed tmp parameter
of update_parent_subparts_cpumask() should not be used at all as
it contains important cpumask data that should not be overwritten.
Fix it by using tmp->addmask instead.

Also update update_cpumask() to make sure that trialcs->cpu_allowed
will not be corrupted until it is no longer needed.

Commit 52f04f10b9 ("thermal: intel: int340x: processor_thermal: Fix
deadlock") addressed deadlock issue during user space trip update. But it
missed a case when thermal zone device is disabled when user writes 0.

Call to thermal_zone_device_disable() also causes deadlock as it also
tries to lock tz->lock, which is already claimed by trip_point_temp_store()
in the thermal core code.

Remove call to thermal_zone_device_disable() in the function
sys_set_trip_temp(), which is called from trip_point_temp_store().

433279beba md: fix regression for null-ptr-deference in __md_stop()
Commit 3e45352259 ("md: Free resources in __md_stop") tried to fix
null-ptr-deference for 'active_io' by moving percpu_ref_exit() to
__md_stop(), however, the commit also moving 'writes_pending' to
__md_stop(), and this will cause mdadm tests broken:

BUG: kernel NULL pointer dereference, address: 0000000000000038
Oops: 0000 [#1] PREEMPT SMP
CPU: 15 PID: 17830 Comm: mdadm Not tainted 6.3.0-rc3-next-20230324-00009-g520d37

And the problem can be reporduced 100% by following test:

mdadm -CR /dev/md0 -l1 -n1 /dev/sda --force
echo inactive > /sys/block/md0/md/array_state
echo read-auto  > /sys/block/md0/md/array_state
echo inactive > /sys/block/md0/md/array_state

Root cause:

// start raid
raid1_run
 mddev_init_writes_pending
  percpu_ref_init

// inactive raid
array_state_store
 do_md_stop
  __md_stop
   percpu_ref_exit

// start raid again
array_state_store
 do_md_run
  raid1_run
   mddev_init_writes_pending
    if (mddev->writes_pending.percpu_count_ptr)
    // won't reinit

// inactive raid again
...
percpu_ref_exit
-> null-ptr-deference

Before the commit, 'writes_pending' is exited when mddev is freed, and
it's safe to restart raid because mddev_init_writes_pending() already make
sure that 'writes_pending' will only be initialized once.

Fix the prblem by moving 'writes_pending' back, it's a litter hard to find
the relationship between alloc memory and free memory, however, code
changes is much less and we lived with this for a long time already.

25bbe844ef drm: test: Fix 32-bit issue in drm_buddy_test
The drm_buddy_test KUnit tests verify that returned blocks have sizes
which are powers of two using is_power_of_2(). However, is_power_of_2()
operations on a 'long', but the block size is a u64. So on systems where
long is 32-bit, this can sometimes fail even on correctly sized blocks.

This only reproduces randomly, as the parameters passed to the buddy
allocator in this test are random. The seed 0xb2e06022 reproduced it
fine here.

For now, just hardcode an is_power_of_2() implementation using
x & (x - 1).

4453545b5b drm: buddy_allocator: Fix buddy allocator init on 32-bit systems
The drm buddy allocator tests were broken on 32-bit systems, as
rounddown_pow_of_two() takes a long, and the buddy allocator handles
64-bit sizes even on 32-bit systems.

This can be reproduced with the drm_buddy_allocator KUnit tests on i386:
	./tools/testing/kunit/kunit.py run --arch i386 \
	--kunitconfig ./drivers/gpu/drm/tests drm_buddy

(It results in kernel BUG_ON() when too many blocks are created, due to
the block size being too small.)

This was independently uncovered (and fixed) by Luís Mendes, whose patch
added a new u64 variant of rounddown_pow_of_two(). This version instead
recalculates the size based on the order.
