The kernel-feat directive passes its argument straight to the shell.
This is unfortunate and unnecessary.
Let's always use paths relative to $srctree/Documentation/ and use
subprocess.check_call() instead of subprocess.Popen(shell=True).
This also makes the code shorter.
This is analogous to commit 3231dd586277 ("docs: kernel_abi.py: fix
command injection") where we did exactly the same thing for
kernel_abi.py, somehow I completely missed this one.

The 'alabaster' theme dropped support for Sphinx < v3.4:
0.7.14 – 2024-01-08
* Dropped support for Python 3.8 and earlier.
* Dropped support for Sphinx 3.3 and earlier.
[...]
(Source: https://alabaster.readthedocs.io/en/latest/changelog.html)
This manifests as an error when running 'make htmldocs' in a virtualenv
constructed from Documentation/sphinx/requirements.txt:
Sphinx version error:
The alabaster extension used by this project needs at least Sphinx v3.4; it therefore cannot be built with this version.
Raising the Sphinx version is not really a good option at this point,
since 3.x through 6.x have horrible performance regressions (7.x still
does, but not quite as bad).
Instead, constrain the 'alabaster' package to versions that still support
Sphinx 2.4.4.

The previous setting did not take into account the CSTN mode.
For the H_WAIT_2 bitfield (bits 0-7) of the LCDC Horizontal Configuration
Register (LCDCR), the IMX25RM manual states that:
In TFT mode, it specifies the number of SCLK periods between the end of
HSYNC and the beginning of OE signal, and the total delay time equals
(H_WAIT_2 + 3) of SCLK periods.
In CSTN mode, it specifies the number of SCLK periods between the end of
HSYNC and the first display data in each line, and the total delay time
equals (H_WAIT_2 + 2) of SCLK periods.
The patch handles both cases.

Pull s390 updates from Alexander Gordeev:
- Add machine variable capacity information to /proc/sysinfo.
- Limit the waste of page tables and always align vmalloc area size and
base address on segment boundary.
- Fix a memory leak when an attempt to register interruption sub class
(ISC) for the adjunct-processor (AP) guest failed.
- Reset response code AP_RESPONSE_INVALID_GISA to understandable by
guest AP_RESPONSE_INVALID_ADDRESS in response to a failed
interruption sub class (ISC) registration attempt.
- Improve reaction to adjunct-processor (AP)
AP_RESPONSE_OTHERWISE_CHANGED response code when enabling interrupts
on behalf of a guest.
- Fix incorrect sysfs 'status' attribute of adjunct-processor (AP)
queue device bound to the vfio_ap device driver when the mediated
device is attached to a guest, but the queue device is not passed
through.
- Rework struct ap_card to hold the whole adjunct-processor (AP) card
hardware information. As result, all the ugly bit checks are replaced
by simple evaluations of the required bit fields.
- Improve handling of some weird scenarios between service element (SE)
host and SE guest with adjunct-processor (AP) pass-through support.
- Change local_ctl_set_bit() and local_ctl_clear_bit() so they return
the previous value of the to be changed control register. This is
useful if a bit is only changed temporarily and the previous content
needs to be restored.
- The kernel starts with machine checks disabled and is expected to
enable it once trap_init() is called. However the implementation
allows machine checks early. Consistently enable it in trap_init()
only.
- local_mcck_disable() and local_mcck_enable() assume that machine
checks are always enabled. Instead implement and use
local_mcck_save() and local_mcck_restore() to disable machine checks
and restore the previous state.
- Modification of floating point control (FPC) register of a traced
process using ptrace interface may lead to corruption of the FPC
register of the tracing process. Fix this.
- kvm_arch_vcpu_ioctl_set_fpu() allows to set the floating point
control (FPC) register in vCPU, but may lead to corruption of the FPC
register of the host process. Fix this.
- Use READ_ONCE() to read a vCPU floating point register value from the
memory mapped area. This avoids that, depending on code generation, a
different value is tested for validity than the one that is used.
- Get rid of test_fp_ctl(), since it is quite subtle to use it
correctly. Instead copy a new floating point control register value
into its save area and test the validity of the new value when
loading it.
- Remove superfluous save_fpu_regs() call.
- Remove s390 support for ARCH_WANTS_DYNAMIC_TASK_STRUCT. All machines
provide the vector facility since many years and the need to make the
task structure size dependent on the vector facility does not exist.
- Remove the "novx" kernel command line option, as the vector code runs
without any problems since many years.
- Add the vector facility to the z13 architecture level set (ALS). All
hypervisors support the vector facility since many years. This allows
compile time optimizations of the kernel.
- Get rid of MACHINE_HAS_VX and replace it with cpu_has_vx(). As
result, the compiled code will have less runtime checks and less
code.
- Convert pgste_get_lock() and pgste_set_unlock() ASM inlines to C.
- Convert the struct subchannel spinlock from pointer to member.

The wording in the current documentation is a little strong. The
intention was not to fix any particular interrupt as wakeup capable but
leave those details to the device. It wasn't intended to enforce any
rules as what can be or can't be a wakeup interrupt.
Soften the wording to not mandate that the 'wakeup-source' property be
used, and clarify what it means when an interrupt is marked (or not
marked) for wakeup.

Pull sysctl updates from Luis Chamberlain:
"To help make the move of sysctls out of kernel/sysctl.c not incur a
size penalty sysctl has been changed to allow us to not require the
sentinel, the final empty element on the sysctl array. Joel Granados
has been doing all this work.
In the v6.6 kernel we got the major infrastructure changes required to
support this. For v6.7 we had all arch/ and drivers/ modified to
remove the sentinel. For v6.8-rc1 we get a few more updates for fs/
directory only.
The kernel/ directory is left but we'll save that for v6.9-rc1 as
those patches are still being reviewed. After that we then can expect
also the removal of the no longer needed check for procname == NULL.
Let us recap the purpose of this work:
- this helps reduce the overall build time size of the kernel and run
time memory consumed by the kernel by about ~64 bytes per array
- the extra 64-byte penalty is no longer inncurred now when we move
sysctls out from kernel/sysctl.c to their own files
Thomas Weißschuh also sent a few cleanups, for v6.9-rc1 we expect to
see further work by Thomas Weißschuh with the constificatin of the
struct ctl_table.
Due to Joel Granados's work, and to help bring in new blood, I have
suggested for him to become a maintainer and he's accepted. So for
v6.9-rc1 I look forward to seeing him sent you a pull request for
further sysctl changes. This also removes Iurii Zaikin as a maintainer
as he has moved on to other projects and has had no time to help at
all"

Pull bcachefs updates from Kent Overstreet:
- btree write buffer rewrite: instead of adding keys to the btree write
buffer at transaction commit time, we now journal them with a
different journal entry type and copy them from the journal to the
write buffer just prior to journal write.
This reduces the number of atomic operations on shared cachelines in
the transaction commit path and is a signicant performance
improvement on some workloads: multithreaded 4k random writes went
from ~650k iops to ~850k iops.
- Bring back optimistic spinning for six locks: the new implementation
doesn't use osq locks; instead we add to the lock waitlist as normal,
and then spin on the lock_acquired bit in the waitlist entry, _not_
the lock itself.
- New ioctls:
- BCH_IOCTL_DEV_USAGE_V2, which allows for new data types
- BCH_IOCTL_OFFLINE_FSCK, which runs the kernel implementation of
fsck but without mounting: useful for transparently using the
kernel version of fsck from 'bcachefs fsck' when the kernel
version is a better match for the on disk filesystem.
- BCH_IOCTL_ONLINE_FSCK: online fsck. Not all passes are supported
yet, but the passes that are supported are fully featured - errors
may be corrected as normal.
The new ioctls use the new 'thread_with_file' abstraction for kicking
off a kthread that's tied to a file descriptor returned to userspace
via the ioctl.
- btree_paths within a btree_trans are now dynamically growable,
instead of being limited to 64. This is important for the
check_directory_structure phase of fsck, and also fixes some issues
we were having with btree path overflow in the reflink btree.
- Trigger refactoring; prep work for the upcoming disk space accounting
rewrite
- Numerous bugfixes :)

Fix the size check added to dns_resolver_preparse() for the V1 server-list
header so that it doesn't give EINVAL if the size supplied is the same as
the size of the header struct (which should be valid).
This can be tested with:
echo -n -e '\0\0\01\xff\0\0' | keyctl padd dns_resolver desc @p
which will give "add_key: Invalid argument" without this fix.

Before commit 7839d0078e0d ("PM: sleep: Fix possible deadlocks in core
system-wide PM code"), the resume of devices that were allowed to resume
asynchronously was scheduled before starting the resume of the other
devices, so the former did not have to wait for the latter unless
functional dependencies were present.
Commit 7839d0078e0d removed that optimization in order to address a
correctness issue, but it can be restored with the help of a new device
power management flag, so do that now.

Suppose we issue two FITRIM ioctls for ranges [0,15] and [16,31] with
mininum length of trimmed range set to 8 blocks. If we have say a range of
blocks 10-22 free, this range will not be trimmed because it straddles the
boundary of the two FITRIM ranges and neither part is big enough. This is a
bit surprising to some users that call FITRIM on smaller ranges of blocks
to limit impact on the system. Also XFS trims all free space extents that
overlap with the specified range so we are inconsistent among filesystems.
Let's change ext4_try_to_trim_range() to consider for trimming the whole
free space extent that straddles the end of specified range, not just the
part of it within the range.

Currently in case the goal length is a multiple of stripe size we use
ext4_mb_scan_aligned() to find the stripe size aligned physical blocks.
In case we are not able to find any, we again go back to calling
ext4_mb_choose_next_group() to search for a different suitable block
group. However, since the linear search always begins from the start,
most of the times we end up with the same BG and the cycle continues.
With large fliesystems, the CPU can be stuck in this loop for hours
which can slow down the whole system. Hence, until we figure out a
better way to continue the search (rather than starting from beginning)
in ext4_mb_choose_next_group(), lets just fallback to
ext4_mb_complex_scan_group() in case aligned scan fails, as it is much
more likely to find the needed blocks.

The ext4 filesystem tracks the trim status of blocks at the group
level. When an entire group has been trimmed then it is marked as
such and subsequent trim invocations with the same minimum trim size
will not be attempted on that group unless it is marked as able to be
trimmed again such as when a block is freed.
Currently the last group can't be marked as trimmed due to incorrect
logic in ext4_last_grp_cluster(). ext4_last_grp_cluster() is supposed
to return the zero based index of the last cluster in a group. This is
then used by ext4_try_to_trim_range() to determine if the trim
operation spans the entire group and as such if the trim status of the
group should be recorded.
ext4_last_grp_cluster() takes a 0 based group index, thus the valid
values for grp are 0..(ext4_get_groups_count - 1). Any group index
less than (ext4_get_groups_count - 1) is not the last group and must
have EXT4_CLUSTERS_PER_GROUP(sb) clusters. For the last group we need
to calculate the number of clusters based on the number of blocks in
the group. Finally subtract 1 from the number of clusters as zero
based indexing is expected. Rearrange the function slightly to make
it clear what we are calculating and returning.
Reproducer:
// Create file system where the last group has fewer blocks than
// blocks per group
$ mkfs.ext4 -b 4096 -g 8192 /dev/nvme0n1 8191
$ mount /dev/nvme0n1 /mnt
Before Patch:
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group not marked as trimmed so second invocation still discards blocks
$ fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
After Patch:
fstrim -v /mnt
/mnt: 25.9 MiB (27156480 bytes) trimmed
// Group marked as trimmed so second invocation DOESN'T discard any blocks
fstrim -v /mnt
/mnt: 0 B (0 bytes) trimmed
