Only a couple of files of the decompressor are compiled with the
minimum architecture level. This is problematic for potential function
calls between compile units, especially if a target function is within
a compile until compiled for a higher architecture level, since that
may lead to an unexpected operation exception.
Therefore compile all files of the decompressor for the same (minimum)
architecture level.

Replace CONFIG_HAVE_MARCH_*_FEATURES with MARCH_HAS_*_FEATURES

Provide MARCH_HAS_*_FEATURES defines which are supposed to be used
everywhere instead of the CONFIG_HAVE_MARCH_*_FEATURES defines.
Various header files contain code which depend on the
CONFIG_HAVE_MARCH_*_FEATURES defines, allowing for compile time
optimizations. If such code is used within the decompressor wrong code may
be generated (the compiler may generate instructions which are not
available for the minimum architecture level of the decompressor).
Therefore provide a new header file with MARCH_HAS_*_FEATURES defines,
which are only available if __DECOMPRESSOR is not defined. This way code
generation for the kernel image is still optimized depending on
CONFIG_HAVE_MARCH_*_FEATURES, while code generated for the decompressor is
compiled for the minimum architecture level.

Disable compile time optimizations of test_facility() for the
decompressor. The decompressor should not contain any optimized code
depending on the architecture level set the kernel image is compiled
for to avoid unexpected operation exceptions.
Add a __DECOMPRESSOR check to test_facility() to enforce that
facilities are always checked during runtime for the decompressor.

The decompressor code is partially compiled with march=z900 so it is
possible to print an error message in case a kernel is booted on a
machine which misses facilities to execute the kernel.
Given that the decompressor code also includes header files from the
core kernel this causes problems for inline assemblies and other code
where the minimum assumed architecture level is set to z10 in the
meantime. If such code is also used in the decompressor (e.g. inline
functions) z900 support must be implemented again.
In order to avoid this and to keep things simple just raise the
minimum architecture level to z10 for the decompressor just like for
the kernel.

The single-queue optimized list flush doesn't have an unplug trace event
to pair with the plug event. Add one.
In the unlikely event an error occurs and falls back to the less
optimized plug flush path, it's possible a 2nd unplug trace event will
be logged, but it will show the remainig count that weren't previously

Since the debugfs_create_dir() never returns a null pointer, checking
the return value for a null pointer is redundant. Since
debugfs_create_file() can deal with a ERR_PTR() style pointer, drop
the check. Since mtip_hw_debugfs_init does not pay attention to the
return value, its return type can be changed to void.

Since there are a few corner cases where the S/G buffer allocation
isn't performed (e.g. depending on IOMMU implementations), it'd be
better to allow the default buffer preallocation size for x86, too.
The default for x86 is still kept to 0, as it should work in most
cases.

The following patchset contains Netfilter updates for net-next:
Patch #1 adds ctnetlink support for kernel side filtering for
deletions, from Changliang Wu.
Patch #2 updates nft_counter support to Use u64_stats_t,
from Sebastian Andrzej Siewior.
Patch #3 uses kmemdup_array() in all xtables frontends,
from Yan Zhen.
Patch #4 is a oneliner to use ERR_CAST() in nf_conntrack instead
opencoded casting, from Shen Lichuan.
Patch #5 removes unused argument in nftables .validate interface,
from Florian Westphal.
Patch #6 is a oneliner to correct a typo in nftables kdoc,
from Simon Horman.
Patch #7 fixes missing kdoc in nftables, also from Simon.
Patch #8 updates nftables to handle timeout less than CONFIG_HZ.
Patch #9 rejects element expiration if timeout is zero,
otherwise it is silently ignored.
Patch #10 disallows element expiration larger than timeout.
Patch #11 removes unnecessary READ_ONCE annotation while mutex is held.
Patch #12 adds missing READ_ONCE/WRITE_ONCE annotation in dynset.
Patch #13 annotates data-races around element expiration.
Patch #14 allocates timeout and expiration in one single set element
extension, they are tighly couple, no reason to keep them
separated anymore.
Patch #15 updates nftables to interpret zero timeout element as never
times out. Note that it is already possible to declare sets
with elements that never time out but this generalizes to all
kind of set with timeouts.
Patch #16 supports for element timeout and expiration updates.

netpoll_srcu is currently used from netpoll_poll_disable() and
__netpoll_cleanup()
Both functions run under RTNL, using netpoll_srcu adds confusion
and no additional protection.
Moreover the synchronize_srcu() call in __netpoll_cleanup() is
performed before clearing np->dev->npinfo, which violates RCU rules.
After this patch, netpoll_poll_disable() and netpoll_poll_enable()
simply use rtnl_dereference().
This saves a big chunk of memory (more than 192KB on platforms
with 512 cpus)

Recently I noticed that both gcc-14 and clang-18 report that passing
a non-string literal as the format argument of alloc_workqueue()
is potentially insecure.
E.g. clang-18 says:
.../rvu.c:2493:32: warning: format string is not a string literal (potentially insecure) [-Wformat-security]
2493 | mw->mbox_wq = alloc_workqueue(name,
| ^~~~
.../rvu.c:2493:32: note: treat the string as an argument to avoid this
2493 | mw->mbox_wq = alloc_workqueue(name,
| ^
| "%s",
It is always the case where the contents of name is safe to pass as the
format argument. That is, in my understanding, it never contains any
format escape sequences.
But, it seems better to be safe than sorry. And, as a bonus, compiler
output becomes less verbose by addressing this issue as suggested by
clang-18.

When asynchronous encryption is used KTLS sends out the final data at
proto->close time. This becomes problematic when the task calling
close() receives a signal. In this case it can happen that
tcp_sendmsg_locked() called at close time returns -ERESTARTSYS and the
final data is not sent.
The described situation happens when KTLS is used in conjunction with
io_uring, as io_uring uses task_work_add() to add work to the current
userspace task. A discussion of the problem along with a reproducer can
be found in [1] and [2]
Fix this by waiting for the asynchronous encryption to be completed on
the final message. With this there is no data left to be sent at close
time.

The ncq_sense_buf buffer field of struct ata_port is allocated and used
only for devices that support the Command Duration Limits (CDL) feature.
However, the cdl buffer of struct ata_device, which is used to cache the
command duration limits log page for devices supporting CDL is always
allocated as part of struct ata_device, which is wasteful of memory for
devices that do not support this feature.
Clean this up by defining both buffers as part of the new ata_cdl
structure and allocating this structure only for devices that support
the CDL feature. This new structure is attached to struct ata_device
using the cdl pointer.
The functions ata_dev_init_cdl_resources() and
ata_dev_cleanup_cdl_resources() are defined to manage this new structure
allocation, initialization and freeing when a port is removed or a
device disabled. ata_dev_init_cdl_resources() is called from
ata_dev_config_cdl() only for devices that support CDL.
ata_dev_cleanup_cdl_resources() is called from ata_dev_free_resources()
to free the ata_cdl structure when a device is being disabled by EH.
Note that the name of the former cdl log buffer of struct ata_device is
changed to desc_log_buf to make it clearer that it is a buffer for the
limit descriptors log page.
This change reduces the size of struct ata_device, thus reducing memory
usage for ATA devices that do not support the CDL feature.

Introduce the function ata_dev_free_resources() to free the resources
allocated to support a device features. For now, this function is
reduced to calling zpodd_exit() for devices that have this feature
enabled.
ata_dev_free_resources() is called from ata_eh_dev_disable() as this
function is always called for all devices attached to a port that is
being detached and for devices that are being disabled due to being
removed (detached) from the system or due to errors.
With this change, the call to zpodd_exit() done in ata_port_detach()
and ata_scsi_handle_link_detach() are removed as these functions
remove all devices attached to the link or port using libata EH, thus
resulting in ata_eh_dev_disable() being called and the zpodd_exit()
function being executed.

The 512B buffer sector_buf field of struct ata_port is used for scanning
devices as well as during error recovery with ata EH. This buffer is
thus useless if a port does not have a device connected to it.
And also given that commands using this buffer are issued to devices,
and not to ports, move this buffer definition from struct ata_port to
struct ata_device.
This change slightly increases system memory usage for systems using a
port-multiplier as in that case we do not need a per-device buffer for
scanning devices (PMP does not allow parallel scanning) nor for EH (as
when entering EH we are guaranteed that all commands to all devices
connected to the PMP have completed or have been aborted). However,
this change reduces memory usage on systems that have many ports with
only few devices rives connected, which is a much more common use case
than the PMP use case.

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.
Although that is not the case here, it is seems best to use ';'
unless ',' is intended.
Found by inspection.
No functional change intended.
Compile tested only.

Merge series from Andre Przywara <andre.przywara@arm.com>:
This is remainder of the AXP717 fix series, containing support for the
boost regulator. This is meant to increase the battery voltage to the 5
volts required to provide the USB VBUS power.
It's the usual trinity of DT bindings patch (1/3), the MFD part
describing the PMIC registers (2/3) and the final patch to model the
regulator (3/3).
Compared to v2, this drops the merged patches, and just retains the
boost related parts. It also changes the internal name of the register
to AXP717_MODULE_EN_CONTROL_2, since there is another control register
we will need later for battery support.

clang warns on this because it has an unannotated fall-through between
cases:
arch/x86/kvm/x86.c:4819:2: error: unannotated fall-through between switch labels [-Werror,-Wimplicit-fallthrough]
and while we could annotate it as a fallthrough, the proper fix is to
just add the break for this case, instead of falling through to the
default case and the break there.
gcc also has that warning, but it looks like gcc only warns for the
cases where they fall through to "real code", rather than to just a
break. Odd.

Since commit a61ddb4393ad ("drm: enable (most) W=1 warnings by default
across the subsystem"), most of the extra warnings in the driver
Makefile are redundant. Remove them.
Note that -Wmissing-declarations and -Wmissing-prototypes are always
enabled by default in scripts/Makefile.extrawarn.
