Add exit hook and remove OPP table when the device gets unregistered.
This will fix the error messages when the CPU FREQ driver module is
removed and then re-inserted. It also fixes these messages while
onlining the first CPU from a policy whose all CPU's were previously
offlined.

cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver
After loading the amd-pstate-ut driver, amd_pstate_ut_check_perf()
and amd_pstate_ut_check_freq() use cpufreq_cpu_get() to get the policy
of the CPU and mark it as busy.
In these functions, cpufreq_cpu_put() should be used to release the
policy, but it is not, so any other entity trying to access the policy
is blocked indefinitely.
One such scenario is when amd_pstate mode is changed, leading to the
following splat:
In amd-pstate-ut, shared memory-based systems call
get_shared_mem() as part of amd_pstate_ut_check_enabled()
function. This function was written when CONFIG_X86_AMD_PSTATE
was tristate config and amd_pstate can be built as a module.
Currently CONFIG_X86_AMD_PSTATE is a boolean config and module
parameter shared_mem is removed. But amd-pstate-ut code still
accesses this module parameter. Remove those accesses.

When the CPU frequency is outdated arch_freq_get_on_cpu()

cpufreq_quick_getpolicy_cur returns the never updated 0.
Thus, the listed frequency might be outside of currently

unique in the freq_table of stats data, this has a time complexity of
O(N^2), where N is the number of frequencies in the freq_table of

However, if the policy.freq_table is already sorted and contains no

blk-mq: release scheduler resource when request completes
Chuck reported [1] an IO hang problem on NFS exports that reside on SATA
devices and bisected to commit 615939a2ae73 ("blk-mq: defer to the normal
submission path for post-flush requests").
We analysed the IO hang problem, found there are two postflush requests
waiting for each other.
The first postflush request completed the REQ_FSEQ_DATA sequence, so go to
the REQ_FSEQ_POSTFLUSH sequence and added in the flush pending list, but
failed to blk_kick_flush() because of the second postflush request which
is inflight waiting in scheduler queue.
The second postflush waiting in scheduler queue can't be dispatched because
the first postflush hasn't released scheduler resource even though it has
completed by itself.
Fix it by releasing scheduler resource when the first postflush request
completed, so the second postflush can be dispatched and completed, then
make blk_kick_flush() succeed.
While at it, remove the check for e->ops.finish_request, as all
schedulers set that. Reaffirm this requirement by adding a WARN_ON_ONCE()
at scheduler registration time, just like we do for insert_requests and
dispatch_request.

btrfs: fix incorrect splitting in btrfs_drop_extent_map_range
In production we were seeing a variety of WARN_ON()'s in the extent_map
code, specifically in btrfs_drop_extent_map_range() when we have to call
add_extent_mapping() for our second split.
Consider the following extent map layout
PINNED
[0 16K) [32K, 48K)
and then we call btrfs_drop_extent_map_range for [0, 36K), with
skip_pinned == true. The initial loop will have
start = 0
end = 36K
len = 36K
we will find the [0, 16k) extent, but since we are pinned we will skip
it, which has this code
start = em_end;
if (end != (u64)-1)
len = start + len - em_end;
em_end here is 16K, so now the values are
start = 16K
len = 16K + 36K - 16K = 36K
len should instead be 20K. This is a problem when we find the next
extent at [32K, 48K), we need to split this extent to leave [36K, 48k),
however the code for the split looks like this
em_end = 48K
split->start = 16K + 36K // this should be 16K + 20K
split->len = 48K - (16K + 36K) // this overflows as 16K + 36K is 52K
and now we have an invalid extent_map in the tree that potentially
overlaps other entries in the extent map. Even in the non-overlapping
case we will have split->start set improperly, which will cause problems
with any block related calculations.
We don't actually need len in this loop, we can simply use end as our
end point, and only adjust start up when we find a pinned extent we need
to skip.
Adjust the logic to do this, which keeps us from inserting an invalid
extent map.
We only skip_pinned in the relocation case, so this is relatively rare,
except in the case where you are running relocation a lot, which can
happen with auto relocation on.

qede: fix firmware halt over suspend and resume
While performing certain power-off sequences, PCI drivers are
called to suspend and resume their underlying devices through
PCI PM (power management) interface. However this NIC hardware
does not support PCI PM suspend/resume operations so system wide
suspend/resume leads to bad MFW (management firmware) state which
causes various follow-up errors in driver when communicating with
the device/firmware afterwards.
To fix this driver implements PCI PM suspend handler to indicate
unsupported operation to the PCI subsystem explicitly, thus avoiding
system to go into suspended/standby mode.
Without this fix device/firmware does not recover unless system
is power cycled.

So the conditions of leaving global pressure are inconstant, which
may lead to the situation that one pressured net-memcg prevents the

This patch fixes this by ignoring the net-memcg's pressure when
deciding whether should leave global memory pressure.

btrfs: only subtract from len_to_oe_boundary when it is tracking an extent
bio_ctrl->len_to_oe_boundary is used to make sure we stay inside a zone
as we submit bios for writes. Every time we add a page to the bio, we
decrement those bytes from len_to_oe_boundary, and then we submit the
bio if we happen to hit zero.
Most of the time, len_to_oe_boundary gets set to U32_MAX.
submit_extent_page() adds pages into our bio, and the size of the bio
ends up limited by:
- Are we contiguous on disk?
- Does bio_add_page() allow us to stuff more in?
- is len_to_oe_boundary > 0?
The len_to_oe_boundary math starts with U32_MAX, which isn't page or
sector aligned, and subtracts from it until it hits zero. In the
non-zoned case, the last IO we submit before we hit zero is going to be
unaligned, triggering BUGs.
This is hard to trigger because bio_add_page() isn't going to make a bio
of U32_MAX size unless you give it a perfect set of pages and fully
contiguous extents on disk. We can hit it pretty reliably while making
large swapfiles during provisioning because the machine is freshly
booted, mostly idle, and the disk is freshly formatted. It's also
possible to trigger with reads when read_ahead_kb is set to 4GB.
The code has been clean up and shifted around a few times, but this flaw
has been lurking since the counter was added. I think the commit 24e6c8082208 ("btrfs: simplify main loop in submit_extent_page") ended
up exposing the bug.
The fix used here is to skip doing math on len_to_oe_boundary unless
we've changed it from the default U32_MAX value. bio_add_page() is the
real limit we want, and there's no reason to do extra math when block
layer is doing it for us.
Sample reproducer, note you'll need to change the path to the bdi and

asm-generic: partially revert "Unify uapi bitsperlong.h for arm64, riscv and loongarch"
Unifying the asm-generic headers across 32-bit and 64-bit architectures
based on the compiler provided macros was a good idea and appears to work
with all user space, but it caused a regression when building old kernels
on systems that have the new headers installed in /usr/include, as this
combination trips an inconsistency in the kernel's own tools/include
headers that are a mix of userspace and kernel-internal headers.
This affects kernel builds on arm64, riscv64 and loongarch64 systems that
might end up using the "#define __BITS_PER_LONG 32" default from the old
tools headers. Backporting the commit into stable kernels would address
this, but it would still break building kernels without that backport,
and waste time for developers trying to understand the problem.
arm64 build machines are rather common, and on riscv64 this can also
happen in practice, but loongarch64 is probably new enough to not
be used much for building old kernels, so only revert the bits
for arm64 and riscv.

that version, we should explicitly specifying Zicsr and Zifencei via -march
to cope with the new changes. but this only occurs when binutils >= 2.36
and GCC >= 11.1.0. It's a different story when binutils < 2.36.
binutils-2.36 supports the Zifencei extension[2] and splits Zifencei and
Zicsr from I[3]. GCC-11.1.0 is particular[4] because it add support Zicsr
and Zifencei extension for -march. binutils-2.35 does not support the
Zifencei extension, and does not need to specify Zicsr and Zifencei when

riscv: uaccess: Return the number of bytes effectively not copied
It was reported that the riscv kernel hangs while executing the test
in [1].
Indeed, the test hangs when trying to write a buffer to a file. The
problem is that the riscv implementation of raw_copy_from_user() does not
return the correct number of bytes not written when an exception happens
and is fixed up, instead it always returns the initial size to copy,
even if some bytes were actually copied.
generic_perform_write() pre-faults the user pages and bails out if nothing
can be written, otherwise it will access the userspace buffer: here the
riscv implementation keeps returning it was not able to copy any byte
though the pre-faulting indicates otherwise. So generic_perform_write()
keeps retrying to access the user memory and ends up in an infinite
loop.
Note that before the commit mentioned in [1] that introduced this
regression, it worked because generic_perform_write() would bail out if
only one byte could not be written.
So fix this by returning the number of bytes effectively not written in
__asm_copy_[to|from]_user() and __clear_user(), as it is expected.
