868e6139c5 block: move lower_48_bits() to block
The function is not generally applicable enough to be included in the core
kernel header. Move it to block since it's the only subsystem using it.

5ad7f18cd8 net: macb: Restart tx only if queue pointer is lagging
commit 4298388574 ("net: macb: restart tx after tx used bit read")
added support for restarting transmission. Restarting tx does not work
in case controller asserts TXUBR interrupt and TQBP is already at the end
of the tx queue. In that situation, restarting tx will immediately cause
assertion of another TXUBR interrupt. The driver will end up in an infinite
interrupt loop which it cannot break out of.

For cases where TQBP is at the end of the tx queue, instead
only clear TX_USED interrupt. As more data gets pushed to the queue,
transmission will resume.

This issue was observed on a Xilinx Zynq-7000 based board.
During stress test of the network interface,
driver would get stuck on interrupt loop within seconds or minutes
causing CPU to stall.

82733d168c io_uring: stop using io_wq_work as an fd placeholder
There are two reasons why this isn't the best idea:

- It's an odd area to grab a bit of storage space, hence it's an odd area
  to grab storage from.
- It puts the 3rd io_kiocb cacheline into the hot path, where normal hot
  path just needs the first two.

Use 'cflags' for joint fd/cflags storage. We only need fd until we
successfully issue, and we only need cflags once a request is done and is
completed.

2804ecd8d3 io_uring: move apoll->events cache
In preparation for fixing a regression with pulling in an extra cacheline
for IO that doesn't usually touch the last cacheline of the io_kiocb,
move the cached location of apoll->events to space shared with some other
completion data. Like cflags, this isn't used until after the request
has been completed, so we can piggy back on top of comp_list.

6f83ab22ad io_uring: io_kiocb_update_pos() should not touch file for non -1 offset
-1 tells use to use the current position, but we check if the file is
a stream regardless of that. Fix up io_kiocb_update_pos() to only
dip into file if we need to. This is both more efficient and also drops
12 bytes of text on aarch64 and 64 bytes on x86-64.

42dcbe7d8b KVM: x86: hyper-v: Avoid writing to TSC page without an active vCPU
The following WARN is triggered from kvm_vm_ioctl_set_clock():

The WARN was introduced by commit 03c0304a86bc ("KVM: Warn if
mark_page_dirty() is called without an active vCPU") but the change seems
to be correct (unlike Hyper-V TSC page update mechanism). In fact, there's
no real need to actually write to guest memory to invalidate TSC page, this
can be done by the first vCPU which goes through kvm_guest_time_update().

There is possible circular locking dependency detected on event_mutex

47b7de6b88 drm/msm/dsi: Use connector directly in msm_dsi_manager_connector_init()
The member 'msm_dsi->connector' isn't assigned until
msm_dsi_manager_connector_init() returns (see msm_dsi_modeset_init() and
how it assigns the return value). Therefore this pointer is going to be
NULL here. Let's use 'connector' which is what was intended.

047ae66557 drm/msm/mdp5: check the return of kzalloc()
kzalloc() is a memory allocation function which can return NULL when
some internal memory errors happen. So it is better to check it to
prevent potential wrong memory access.

Besides, since mdp5_plane_reset() is void type, so we should better
set `plane-state` to NULL after releasing it.

e8a64bbaaa net/sched: taprio: Check if socket flags are valid
A user may set the SO_TXTIME socket option to ensure a packet is send
at a given time. The taprio scheduler has to confirm, that it is allowed
to send a packet at that given time, by a check against the packet time
schedule. The scheduler drop the packet, if the gates are closed at the
given send time.

The check, if SO_TXTIME is set, may fail since sk_flags are part of an
union and the union is used otherwise. This happen, if a socket is not
a full socket, like a request socket for example.

Add a check to verify, if the union is used for sk_flags.

400331f8ff x86/tsx: Disable TSX development mode at boot
A microcode update on some Intel processors causes all TSX transactions
to always abort by default[*]. Microcode also added functionality to
re-enable TSX for development purposes. With this microcode loaded, if
tsx=on was passed on the cmdline, and TSX development mode was already
enabled before the kernel boot, it may make the system vulnerable to TSX
Asynchronous Abort (TAA).

To be on safer side, unconditionally disable TSX development mode during
boot. If a viable use case appears, this can be revisited later.

08d835dff9 genirq/affinity: Consider that CPUs on nodes can be unbalanced
If CPUs on a node are offline at boot time, the number of nodes is
different when building affinity masks for present cpus and when building
affinity masks for possible cpus. This causes the following problem:

In the case that the number of vectors is less than the number of nodes
there are cases where bits of masks for present cpus are overwritten when
building masks for possible cpus.

Fix this by excluding CPUs, which are not part of the current build mask
(present/possible).

1acb34e7dd drm/i915: Sunset igpu legacy mmap support based on GRAPHICS_VER_FULL
The intent of the version check in the mmap ioctl was to maintain
support for existing platforms (i.e., ADL/RPL and earlier), but drop
support on all future igpu platforms.  As we've seen on the dgpu side,
the hardware teams are using a more fine-grained numbering system for IP
version numbers these days, so it's possible the version number
associated with our next igpu could be some form of "12.xx" rather than
13 or higher.  Comparing against the full ver.release number will ensure
the intent of the check is maintained no matter what numbering the
hardware teams settle on.

4ea3c64252 powerpc fixes for 5.18 #2
- Fix KVM "lost kick" race, where an attempt to pull a vcpu out of the guest could be
    lost (or delayed until the next guest exit).
 
  - Disable SCV (system call vectored) when PR KVM guests could be run.
 
  - Fix KVM PR guests using SCV, by disallowing AIL != 0 for KVM PR guests.
 
  - Add a new KVM CAP to indicate if AIL == 3 is supported.
 
  - Fix a regression when hotplugging a CPU to a memoryless/cpuless node.
 
  - Make virt_addr_valid() stricter for 64-bit Book3E & 32-bit, which fixes crashes seen
    due to hardened usercopy.
 
  - Revert a change to max_mapnr which broke HIGHMEM.

5a6b06f592 ath9k: Fix usage of driver-private space in tx_info
The ieee80211_tx_info_clear_status() helper also clears the rate counts and
the driver-private part of struct ieee80211_tx_info, so using it breaks
quite a few other things. So back out of using it, and instead define a
ath-internal helper that only clears the area between the
status_driver_data and the rates info. Combined with moving the
ath_frame_info struct to status_driver_data, this avoids clearing anything
we shouldn't be, and so we can keep the existing code for handling the rate
information.

While fixing this I also noticed that the setting of
tx_info->status.rates[tx_rateindex].count on hardware underrun errors was
always immediately overridden by the normal setting of the same fields, so
rearrange the code so that the underrun detection actually takes effect.

The new helper could be generalised to a 'memset_between()' helper, but
leave it as a driver-internal helper for now since this needs to go to
stable.

40e97e4296 tick/nohz: Use WARN_ON_ONCE() to prevent console saturation
While running some testing on code that happened to allow the variable
tick_nohz_full_running to get set but with no "possible" NOHZ cores to
back up that setting, this warning triggered:

        if (unlikely(tick_do_timer_cpu == TICK_DO_TIMER_NONE))
                WARN_ON(tick_nohz_full_running);

The console was overwhemled with an endless stream of one WARN per tick
per core and there was no way to even see what was going on w/o using a
serial console to capture it and then trace it back to this.

Change it to WARN_ON_ONCE().

Fixes: 08ae95f4fd ("nohz_full: Allow the boot CPU to be nohz_full")

1862a69c91 perf tools fixes for v5.18: 1st batch
- Fix the clang command line option probing and remove some options to filter
   out, fixing the build with the latest clang versions.
 
 - Fix 'perf bench' futex and epoll benchmarks to deal with machines with more
   than 1K CPUs.
 
 - Fix 'perf test tsc' error message when not supported.
 
 - Remap perf ring buffer if there is no space for event, fixing perf usage
   in 32-bit ChromeOS.
 
 - Drop objdump stderr to avoid getting stuck waiting for stdout output in
   'perf annotate'.
 
 - Fix up garbled output by now showing unwind error messages when augmenting
   frame in best effort mode.
 
 - Fix perf's libperf_print callback, use the va_args eprintf() variant.
 
 - Sync vhost and arm64 cputype headers with the kernel sources.
 
 - Fix 'perf report --mem-mode' with ARM SPE.
 
 - Add missing external commands ('perf iiostat', etc) to 'perf --list-cmds'.
