block: remove obsolete config BLOCK_COMPAT
Before commit
bdc1ddad3e5f ("compat_ioctl: block: move
blkdev_compat_ioctl() into ioctl.c"), the config BLOCK_COMPAT was used to
include compat_ioctl.c into the kernel build. With this commit, the code
is moved into ioctl.c and included with the config COMPAT. So, since then,
the config BLOCK_COMPAT has no effect and any further purpose.
Remove this obsolete config BLOCK_COMPAT.

Mark reports an issue with the recent patches coalescing compound pages
while registering them in io_uring. The reason is that we try to drop
excessive references with folio_put_refs(), but pages were acquired
with pin_user_pages(), which has extra accounting and so should be put
down with matching unpin_user_pages() or at least gup_put_folio().
As a fix unpin_user_pages() all but first page instead, and let's figure
out a better API after.

nvme-tcp: fix opcode reporting in the timeout handler
For non in-capsule writes we reuse the request pdu space for a h2cdata
pdu in order to avoid over allocating space (either preallocate or
dynamically upon receving an r2t pdu). However if the request times out
the core expects to find the opcode in the start of the request, which
we override.
In order to prevent that, without sacrificing additional 24 bytes per
request, we just use the tail of the command pdu space instead (last
24 bytes from the 72 bytes command pdu). That should make the command
opcode always available, and we get away from allocating more space.
If in the future we would need the last 24 bytes of the nvme command
available we would need to allocate a dedicated space for it in the
request, but until then we can avoid doing so.

block: null_blk: Fix handling of fake timeout request
When injecting a fake timeout into the null_blk driver using
fail_io_timeout, the request timeout handler does not execute
blk_mq_complete_request(), so the complete callback is never executed
for a timedout request.
The null_blk driver also has a driver-specific fake timeout mechanism
which does not have this problem. Fix the problem with fail_io_timeout
by using the same meachanism as null_blk internal timeout feature, using
the fake_timeout field of null_blk commands.

powerpc/mm: Fix false detection of read faults
To support detection of read faults with Radix execute-only memory, the
vma_is_accessible() check in access_error() (which checks for PROT_NONE)
was replaced with a check to see if VM_READ was missing, and if so,
returns true to assert the fault was caused by a bad read.
This is incorrect, as it ignores that both VM_WRITE and VM_EXEC imply
read on powerpc, as defined in protection_map[]. This causes mappings
containing VM_WRITE or VM_EXEC without VM_READ to misreport the cause of
page faults, since the MMU is still allowing reads.
Correct this by restoring the original vma_is_accessible() check for
PROT_NONE mappings, and adding a separate check for Radix PROT_EXEC-only
mappings.

sched_getaffinity: don't assume 'cpumask_size()' is fully initialized
The getaffinity() system call uses 'cpumask_size()' to decide how big
the CPU mask is - so far so good. It is indeed the allocation size of a
cpumask.
But the code also assumes that the whole allocation is initialized
without actually doing so itself. That's wrong, because we might have
fixed-size allocations (making copying and clearing more efficient), but
not all of it is then necessarily used if 'nr_cpu_ids' is smaller.
Having checked other users of 'cpumask_size()', they all seem to be ok,
either using it purely for the allocation size, or explicitly zeroing
the cpumask before using the size in bytes to copy it.
See for example the ublk_ctrl_get_queue_affinity() function that uses
the proper 'zalloc_cpumask_var()' to make sure that the whole mask is
cleared, whether the storage is on the stack or if it was an external
allocation.
Fix this by just zeroing the allocation before using it. Do the same
for the compat version of sched_getaffinity(), which had the same logic.
Also, for consistency, make sched_getaffinity() use 'cpumask_bits()' to
access the bits. For a cpumask_var_t, it ends up being a pointer to the
same data either way, but it's just a good idea to treat it like you
would a 'cpumask_t'. The compat case already did that.

tracing: Make tracepoint lockdep check actually test something
A while ago where the trace events had the following:
rcu_read_lock_sched_notrace();
rcu_dereference_sched(...);
rcu_read_unlock_sched_notrace();
If the tracepoint is enabled, it could trigger RCU issues if called in
the wrong place. And this warning was only triggered if lockdep was
enabled. If the tracepoint was never enabled with lockdep, the bug would
not be caught. To handle this, the above sequence was done when lockdep
was enabled regardless if the tracepoint was enabled or not (although the
always enabled code really didn't do anything, it would still trigger a
warning).
But a lot has changed since that lockdep code was added. One is, that
sequence no longer triggers any warning. Another is, the tracepoint when
enabled doesn't even do that sequence anymore.
The main check we care about today is whether RCU is "watching" or not.
So if lockdep is enabled, always check if rcu_is_watching() which will
trigger a warning if it is not (tracepoints require RCU to be watching).
Note, that old sequence did add a bit of overhead when lockdep was enabled,
and with the latest kernel updates, would cause the system to slow down
enough to trigger kernel "stalled" warnings.

ACPI: PPTT: Fix to avoid sleep in the atomic context when PPTT is absent
Commit
0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage")
enabled to map PPTT once on the first invocation of acpi_get_pptt() and
never unmapped the same allowing it to be used at runtime with out the
hassle of mapping and unmapping the table. This was needed to fetch LLC
information from the PPTT in the cpuhotplug path which is executed in
the atomic context as the acpi_get_table() might sleep waiting for a
mutex.
However it missed to handle the case when there is no PPTT on the system
which results in acpi_get_pptt() being called from all the secondary
CPUs attempting to fetch the LLC information in the atomic context
without knowing the absence of PPTT resulting in the splat like below:

pm-graph: sleepgraph: Avoid crashing on binary data in device names
A regression has occurred in the hid-sensor code where a device
name string has not been initialized to 0, and ends up without
a NULL char and is printed with %s. This includes random binary
data in the device name, which makes its way into the ftrace output
and ends up crashing sleepgraph because it expects the ftrace output
to be ASCII only.
For example: "HID-SENSOR-INT-020b?.39.auto" ends up in ftrace instead
of "HID-SENSOR-INT-020b.39.auto". It causes this crash in sleepgraph:
File "/usr/bin/sleepgraph", line 5579, in executeSuspend
for line in fp:
File "/usr/lib/python3.10/codecs.py", line 322, in decode
(result, consumed) = self._buffer_decode(data, self.errors, final)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xff in position
1568: invalid start byte
The issue is present in 6.3-rc1 and is described in full here:
https://bugzilla.kernel.org/show_bug.cgi?id=217169
A separate fix has been submitted to have this issue repaired, but
it has also exposed a larger bug in sleepgraph, since nothing should
make sleepgraph crash. Sleepgraph needs to be able to handle binary
data showing up in ftrace gracefully.
Modify the ftrace processing code to treat it as potentially binary
and to filter out binary data and leave just the ASCII.

block: do not reverse request order when flushing plug list
Commit
26fed4ac4eab ("block: flush plug based on hardware and software
queue order") changed flushing of plug list to submit requests one
device at a time. However while doing that it also started using
list_add_tail() instead of list_add() used previously thus effectively
submitting requests in reverse order. Also when forming a rq_list with
remaining requests (in case two or more devices are used), we
effectively reverse the ordering of the plug list for each device we
process. Submitting requests in reverse order has negative impact on
performance for rotational disks (when BFQ is not in use). We observe
10-25% regression in random 4k write throughput, as well as ~20%
regression in MariaDB OLTP benchmark on rotational storage on btrfs
filesystem.
Fix the problem by preserving ordering of the plug list when inserting
requests into the queuelist as well as by appending to requeue_list
instead of prepending to it.

drm/amdgpu/vcn: Disable indirect SRAM on Vangogh broken BIOSes
The VCN firmware loading path enables the indirect SRAM mode if it's
advertised as supported. We might have some cases of FW issues that
prevents this mode to working properly though, ending-up in a failed
probe. An example below, observed in the Steam Deck:
[...]
[drm] failed to load ucode VCN0_RAM(0x3A)
[drm] psp gfx command LOAD_IP_FW(0x6) failed and response status is (0xFFFF0000)
amdgpu 0000:04:00.0: [drm:amdgpu_ring_test_helper [amdgpu]] *ERROR* ring vcn_dec_0 test failed (-110)

amdgpu 0000:04:00.0: amdgpu: amdgpu_device_ip_init failed
amdgpu 0000:04:00.0: amdgpu: Fatal error during GPU init
[...]
Disabling the VCN block circumvents this, but it's a very invasive
workaround that turns off the entire feature. So, let's add a quirk
on VCN loading that checks for known problematic BIOSes on Vangogh,
so we can proactively disable the indirect SRAM mode and allow the
HW proper probe and VCN IP block to work fine.
