In the struct address_space, there is a 32-byte gap between i_mmap
and i_mmap_rwsem. Due to the alignment of struct address_space
variables to 8 bytes, in certain situations, i_mmap and i_mmap_rwsem
may end up in the same CACHE line.
While running Unixbench/execl, we observe high false sharing issues
when accessing i_mmap against i_mmap_rwsem. We move i_mmap_rwsem
after i_private_list, ensuring a 64-byte gap between i_mmap and
i_mmap_rwsem.
For Intel Silver machines (2 sockets) using kernel v6.8 rc-2, the score
of Unixbench/execl improves by ~3.94%, and the score of Unixbench/shell
improves by ~3.26%.

The only generic interface to execute asynchronously in the BH context is
tasklet; however, it's marked deprecated and has some design flaws such as
the execution code accessing the tasklet item after the execution is
complete which can lead to subtle use-after-free in certain usage scenarios
and less-developed flush and cancel mechanisms.
This patch implements BH workqueues which share the same semantics and
features of regular workqueues but execute their work items in the softirq
context. As there is always only one BH execution context per CPU, none of
the concurrency management mechanisms applies and a BH workqueue can be
thought of as a convenience wrapper around softirq.
Except for the inability to sleep while executing and lack of max_active
adjustments, BH workqueues and work items should behave the same as regular
workqueues and work items.
Currently, the execution is hooked to tasklet[_hi]. However, the goal is to
convert all tasklet users over to BH workqueues. Once the conversion is
complete, tasklet can be removed and BH workqueues can directly take over
the tasklet softirqs.
system_bh[_highpri]_wq are added. As queue-wide flushing doesn't exist in
tasklet, all existing tasklet users should be able to use the system BH
workqueues without creating their own workqueues.
v3: - Add missing interrupt.h include.
v2: - Instead of using tasklets, hook directly into its softirq action
functions - tasklet[_hi]_action(). This is slightly cheaper and closer
to the eventual code structure we want to arrive at. Suggested by Lai.
- Lai also pointed out several places which need NULL worker->task
handling or can use clarification. Updated.

Aligning the buffer to the L1 cache is not sufficient in some platforms
as they might have larger cacheline sizes for caches after L1 and thus,
we can't guarantee DMA safety.
That was the whole reason to introduce IIO_DMA_MINALIGN in [1]. Do the same
for st_sensors common buffer.
While at it, moved the odr_lock before buffer_data as we definitely
don't want any other data to share a cacheline with the buffer.

CXL events were rerouted though the CXL subsystem for additional
processing. However, when that work was done it was missed that
cper_estatus_print_section() continued with a generic error message
which is confusing.
Teach CPER print code to ignore printing details of some section types.
Assign the CXL event GUIDs to this set to prevent confusing unknown
prints.

When the width of a fill is smaller than the width of the preceding
spill, the information about scalar boundaries can still be preserved,
as long as it's coerced to the right width (done by coerce_reg_to_size).
Even further, if the actual value fits into the fill width, the ID can
be preserved as well for further tracking of equal scalars.
Implement the above improvements, which makes narrowing fills behave the
same as narrowing spills and MOVs between registers.
Two tests are adjusted to accommodate for endianness differences and to
take into account that it's now allowed to do a narrowing fill from the
least significant bits.
reg_bounds_sync is added to coerce_reg_to_size to correctly adjust
umin/umax boundaries after the var_off truncation, for example, a 64-bit
value 0xXXXXXXXX00000000, when read as a 32-bit, gets umin = 0, umax =
0xFFFFFFFF, var_off = (0x0; 0xffffffff00000000), which needs to be
synced down to umax = 0, otherwise reg_bounds_sanity_check doesn't pass.

The macros are preparation for adding module aliases en mass in a
separate commit.
Although it would be tempting to create aliases like cls-foo for name
cls_foo, this could not be used because modprobe utilities treat '-' and
'_' interchangeably.
In the end, the naming follows pattern of proto modules in linux/net.h.

All users are already assigning a const char * to the `governor_name`
member of struct thermal_zone_params and to the `name` member of
struct thermal_governor.
Even if users are technically wrong, it just makes more sense to change
this member to be a const char pointer instead of doing the other way
around.

With this flag:
- pidfd_open() doesn't require that the target task must be
a thread-group leader
- pidfd_poll() succeeds when the task exits and becomes a
zombie (iow, passes exit_notify()), even if it is a leader
and thread-group is not empty.
This means that the behaviour of pidfd_poll(PIDFD_THREAD,
pid-of-group-leader) is not well defined if it races with
exec() from its sub-thread; pidfd_poll() can succeed or not
depending on whether pidfd_task_exited() is called before
or after exchange_tids().
Perhaps we can improve this behaviour later, pidfd_poll()
can probably take sig->group_exec_task into account. But
this doesn't really differ from the case when the leader
exits before other threads (so pidfd_poll() succeeds) and
then another thread execs and pidfd_poll() will block again.
thread_group_exited() is no longer used, perhaps it can die.

- make pidfd_create() static.
- Don't pass O_RDWR | O_CLOEXEC to __pidfd_prepare() in copy_process(),
__pidfd_prepare() adds these flags unconditionally.
- Kill the flags check in __pidfd_prepare(). sys_pidfd_open() checks the
flags itself, all other users of pidfd_prepare() pass flags = 0.
If we need a sanity check for those other in kernel users then
WARN_ON_ONCE(flags & ~PIDFD_NONBLOCK) makes more sense.
- Don't pass O_RDWR to get_unused_fd_flags(), it ignores everything except
O_CLOEXEC.

We recently added some validation that we don't try to
connect to an AP that is currently in a channel switch
process, since that might want the channel to be quiet
or we might not be able to connect in time to hear the
switching in a beacon. This was in commit c09c4f31998b
("wifi: mac80211: don't connect to an AP while it's in
a CSA process").
However, we promptly got a report that this caused new
connection failures, and it turns out that the AP that
we now cannot connect to is permanently advertising an
extended channel switch announcement, even with quiet.
The AP in question was an Asus RT-AC53, with firmware
3.0.0.4.380_10760-g21a5898.
As a first step, attempt to detect that we're dealing
with such a situation, so mac80211 can use this later.

This patch creates wordpart.h and includes it in asm/word-at-a-time.h
for all architectures. WORD_AT_A_TIME_CONSTANTS depends on kernel.h
because of REPEAT_BYTE. Moving this to another header and including it
where necessary allows us to not include the bloated kernel.h. Making
this implicit dependency on REPEAT_BYTE explicit allows for later
improvements in the lib/string.c inclusion list.

The ->map_blocks interface returns a valid range for writeback, but we
still call back into it for every block, which is a bit inefficient.
Change iomap_writepage_map to use the valid range in the map until the
end of the folio or the dirty range inside the folio instead of calling
back into every block.
Note that the range is not used over folio boundaries as we need to be
able to check the mapping sequence count under the folio lock.

Back in the days when a single bio could only be filled to the hardware
limits, and we scheduled a work item for each bio completion, chaining
multiple bios for a single ioend made a lot of sense to reduce the number
of completions. But these days bios can be filled until we reach the
number of vectors or total size limit, which means we can always fit at
least 1 megabyte worth of data in the worst case, but usually a lot more
due to large folios. The only thing bio chaining is buying us now is
to reduce the size of the allocation from an ioend with an embedded bio
into a plain bio, which is a 52 bytes differences on 64-bit systems.
This is not worth the added complexity, so remove the bio chaining and
only use the bio embedded into the ioend. This will help to simplify
further changes to the iomap writeback code.

If the "spk-id-gpios" property is present it points to GPIOs whose
value must be used to select the correct bin file to match the
speakers.
Some manufacturers use multiple sources of speakers, which need
different tunings for best performance. On these models the type of
speaker fitted is indicated by the values of one or more GPIOs. The
number formed by the GPIOs identifies the tuning required.
The speaker ID must be used in combination with the subsystem ID
(either from PCI SSID or cirrus,firmware-uid property), because the
GPIOs can only indicate variants of a specific model.
