   - Fix affinity setting for SQPOLL based io-wq (me)

   - Remove the io_uring userspace code. These were added initially as
     copies from liburing, but all of them have since bitrotted and are
     way out of date at this point. Rather than attempt to keep them in
     sync, just get rid of them. People will have liburing available

adfd671676 sysctl-6.6-rc1 
Long ago we set out to remove the kitchen sink on kernel/sysctl.c arrays and
 placings sysctls to their own sybsystem or file to help avoid merge conflicts.
 Matthew Wilcox pointed out though that if we're going to do that we might as
 well also *save* space while at it and try to remove the extra last sysctl
 entry added at the end of each array, a sentintel, instead of bloating the
 kernel by adding a new sentinel with each array moved.
 
 Doing that was not so trivial, and has required slowing down the moves of
 kernel/sysctl.c arrays and measuring the impact on size by each new move.
 
 The complex part of the effort to help reduce the size of each sysctl is being
 done by the patient work of el señor Don Joel Granados. A lot of this is truly
 painful code refactoring and testing and then trying to measure the savings of
 each move and removing the sentinels. Although Joel already has code which does
 most of this work, experience with sysctl moves in the past shows is we need to
 be careful due to the slew of odd build failures that are possible due to the
 amount of random Kconfig options sysctls use.
 
 To that end Joel's work is split by first addressing the major housekeeping
 needed to remove the sentinels, which is part of this merge request. The rest
 of the work to actually remove the sentinels will be done later in future
 kernel releases.
 
 At first I was only going to send his first 7 patches of his patch series,
 posted 1 month ago, but in retrospect due to the testing the changes have
 received in linux-next and the minor changes they make this goes with the
 entire set of patches Joel had planned: just sysctl house keeping. There are
 networking changes but these are part of the house keeping too.
 
 The preliminary math is showing this will all help reduce the overall build
 time size of the kernel and run time memory consumed by the kernel by about
 ~64 bytes per array where we are able to remove each sentinel in the future.
 That also means there is no more bloating the kernel with the extra ~64 bytes
 per array moved as no new sentinels are created.
 
 Most of this has been in linux-next for about a month, the last 7 patches took
 a minor refresh 2 week ago based on feedback.

daa22f5a78 Modules changes for v6.6-rc1 
Summary of the changes worth highlighting from most interesting to boring below:
 
   * Christoph Hellwig's symbol_get() fix to Nvidia's efforts to circumvent the
     protection he put in place in year 2020 to prevent proprietary modules from
     using GPL only symbols, and also ensuring proprietary modules which export
     symbols grandfather their taint. That was done through year 2020 commit
     262e6ae708 ("modules: inherit TAINT_PROPRIETARY_MODULE"). Christoph's new
     fix is done by clarifing __symbol_get() was only ever intended to prevent
     module reference loops by Linux kernel modules and so making it only find
     symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic used
     by Nvidia was to use symbol_get() to purposely swift through proprietary
     module symbols and completley bypass our traditional EXPORT_SYMBOL*()
     annotations and community agreed upon restrictions.
 
     A small set of preamble patches fix up a few symbols which just needed
     adjusting for this on two modules, the rtc ds1685 and the networking enetc
     module. Two other modules just needed some build fixing and removal of use
     of __symbol_get() as they can't ever be modular, as was done by Arnd on
     the ARM pxa module and Christoph did on the mmc au1xmmc driver.
 
     This is a good reminder to us that symbol_get() is just a hack to address
     things which should be fixed through Kconfig at build time as was done in
     the later patches, and so ultimately it should just go.
 
   * Extremely late minor fix for old module layout 055f23b74b ("module: check
     for exit sections in layout_sections() instead of module_init_section()") by
     James Morse for arm64. Note that this layout thing is old, it is *not*
     Song Liu's commit ac3b432839 ("module: replace module_layout with
     module_memory"). The issue however is very odd to run into and so there was
     no hurry to get this in fast.
 
   * Although the fix did not go through the modules tree I'd like to highlight
     the fix by Peter Zijlstra in commit 5409730962 ("x86/static_call: Fix
     __static_call_fixup()") now merged in your tree which came out of what
     was originally suspected to be a fallout of the the newer module layout
     changes by Song Liu commit ac3b432839 ("module: replace module_layout
     with module_memory") instead of module_init_section()"). Thanks to the report
     by Christian Bricart and the debugging by Song Liu & Peter that turned to
     be noted as a kernel regression in place since v5.19 through commit
     ee88d363d1 ("x86,static_call: Use alternative RET encoding").
 
     I highlight this to reflect and clarify that we haven't seen more fallout
     from ac3b432839 ("module: replace module_layout with module_memory").
 
   * RISC-V toolchain got mapping symbol support which prefix symbols with "$"
     to help with alignment considerations for disassembly. This is used to
     differentiate between incompatible instruction encodings when disassembling.
     RISC-V just matches what ARM/AARCH64 did for alignment considerations and
     Palmer Dabbelt extended is_mapping_symbol() to accept these symbols for
     RISC-V. We already had support for this for all architectures but it also
     checked for the second character, the RISC-V check Dabbelt added was just
     for the "$". After a bit of testing and fallout on linux-next and based on
     feedback from Masahiro Yamada it was decided to simplify the check and treat
     the first char "$" as unique for all architectures, and so we no make
     is_mapping_symbol() for all archs if the symbol starts with "$".
 
     The most relevant commit for this for RISC-V on binutils was:
 
     https://sourceware.org/pipermail/binutils/2021-July/117350.html
 
   * A late fix by Andrea Righi (today) to make module zstd decompression use
     vmalloc() instead of kmalloc() to account for large compressed modules. I
     suspect we'll see similar things for other decompression algorithms soon.
 
   * samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and Chen Jiahao

 "Summary of the changes worth highlighting from most interesting to
  boring below:

   - Christoph Hellwig's symbol_get() fix to Nvidia's efforts to
     circumvent the protection he put in place in year 2020 to prevent
     proprietary modules from using GPL only symbols, and also ensuring
     proprietary modules which export symbols grandfather their taint.

     That was done through year 2020 commit 262e6ae708 ("modules:
     inherit TAINT_PROPRIETARY_MODULE"). Christoph's new fix is done by
     clarifing __symbol_get() was only ever intended to prevent module
     reference loops by Linux kernel modules and so making it only find
     symbols exported via EXPORT_SYMBOL_GPL(). The circumvention tactic
     used by Nvidia was to use symbol_get() to purposely swift through
     proprietary module symbols and completely bypass our traditional
     EXPORT_SYMBOL*() annotations and community agreed upon
     restrictions.

     A small set of preamble patches fix up a few symbols which just
     needed adjusting for this on two modules, the rtc ds1685 and the
     networking enetc module. Two other modules just needed some build
     fixing and removal of use of __symbol_get() as they can't ever be
     modular, as was done by Arnd on the ARM pxa module and Christoph
     did on the mmc au1xmmc driver.

     This is a good reminder to us that symbol_get() is just a hack to
     address things which should be fixed through Kconfig at build time
     as was done in the later patches, and so ultimately it should just
     go.

   - Extremely late minor fix for old module layout 055f23b74b
     ("module: check for exit sections in layout_sections() instead of
     module_init_section()") by James Morse for arm64. Note that this
     layout thing is old, it is *not* Song Liu's commit ac3b432839
     ("module: replace module_layout with module_memory"). The issue
     however is very odd to run into and so there was no hurry to get
     this in fast.

   - Although the fix did not go through the modules tree I'd like to
     highlight the fix by Peter Zijlstra in commit 5409730962
     ("x86/static_call: Fix __static_call_fixup()") now merged in your
     tree which came out of what was originally suspected to be a
     fallout of the the newer module layout changes by Song Liu commit
     ac3b432839 ("module: replace module_layout with module_memory")
     instead of module_init_section()"). Thanks to the report by
     Christian Bricart and the debugging by Song Liu & Peter that turned
     to be noted as a kernel regression in place since v5.19 through
     commit ee88d363d1 ("x86,static_call: Use alternative RET
     encoding").

     I highlight this to reflect and clarify that we haven't seen more
     fallout from ac3b432839 ("module: replace module_layout with
     module_memory").

   - RISC-V toolchain got mapping symbol support which prefix symbols
     with "$" to help with alignment considerations for disassembly.

     This is used to differentiate between incompatible instruction
     encodings when disassembling. RISC-V just matches what ARM/AARCH64
     did for alignment considerations and Palmer Dabbelt extended
     is_mapping_symbol() to accept these symbols for RISC-V. We already
     had support for this for all architectures but it also checked for
     the second character, the RISC-V check Dabbelt added was just for
     the "$". After a bit of testing and fallout on linux-next and based
     on feedback from Masahiro Yamada it was decided to simplify the
     check and treat the first char "$" as unique for all architectures,
     and so we no make is_mapping_symbol() for all archs if the symbol
     starts with "$".

     The most relevant commit for this for RISC-V on binutils was:

       https://sourceware.org/pipermail/binutils/2021-July/117350.html

   - A late fix by Andrea Righi (today) to make module zstd
     decompression use vmalloc() instead of kmalloc() to account for
     large compressed modules. I suspect we'll see similar things for
     other decompression algorithms soon.

   - samples/hw_breakpoint minor fixes by Rong Tao, Arnd Bergmann and
     Chen Jiahao"

f208e9508a SUNRPC: Count ingress RPC messages per svc_pool 
svc_xprt_enqueue() can be costly, since it involves selecting and
waking up a process.

More than one enqueue is done per incoming RPC. For example,
svc_data_ready() enqueues, and so does svc_xprt_receive(). Also, if
an RPC message requires more than one call to ->recvfrom() to
receive it fully, each one of those calls does an enqueue.

To get a sense of the average number of transport enqueue operations
needed to process an incoming RPC message, re-use the "packets" pool
stat. Track the number of complete RPC messages processed by each
thread pool.

850bac3ae4 SUNRPC: Deduplicate thread wake-up code 
Refactor: Extract the loop that finds an idle service thread from
svc_xprt_enqueue() and svc_wake_up(). Both functions do just about
the same thing.

Note that svc_wake_up() currently does not hold the RCU read lock
while waking the target thread. It indeed should hold the lock, just
as svc_xprt_enqueue() does, to ensure the rqstp does not vanish
during the wake-up. This patch adds the RCU lock for svc_wake_up().

Note that shrinking the pool thread count is rare, and calls to
svc_wake_up() are also quite infrequent. In practice, this race is
very unlikely to be hit, so we are not marking the lock fix for
stable backport at this time.

82e5d82a45 SUNRPC: Move trace_svc_xprt_enqueue 
The xpt_flags field frequently changes between the time that
svc_xprt_ready() grabs a copy and execution flow arrives at the
tracepoint at the tail of svc_xprt_enqueue(). In fact, there's
usually a sleep/wake-up in there, so those flags are almost
guaranteed to be different.

It would be more useful to record the exact flags that were used to
decide whether the transport is ready, so move the tracepoint.

Moving it means the tracepoint can't pick up the waker's pid. That
can be added to struct svc_rqst if it turns out that is important.

c743b4259c SUNRPC: remove timeout arg from svc_recv() 
Most svc threads have no interest in a timeout.
nfsd sets it to 1 hour, but this is a wart of no significance.

lockd uses the timeout so that it can call nlmsvc_retry_blocked().
It also sometimes calls svc_wake_up() to ensure this is called.

So change lockd to be consistent and always use svc_wake_up() to trigger
nlmsvc_retry_blocked() - using a timer instead of a timeout to
svc_recv().

And change svc_recv() to not take a timeout arg.

This makes the sp_threads_timedout counter always zero.

svc_recv() currently returns a 0 on success or one of two errors:
 - -EAGAIN means no message was successfully received
 - -EINTR means the thread has been told to stop

Previously nfsd would stop as the result of a signal as well as
following kthread_stop().  In that case the difference was useful: EINTR
means stop unconditionally.  EAGAIN means stop if kthread_should_stop(),
continue otherwise.

Now threads only exit when kthread_should_stop() so we don't need the
distinction.

18e4cf9155 nfsd: Simplify code around svc_exit_thread() call in nfsd() 
Previously a thread could exit asynchronously (due to a signal) so some
care was needed to hold nfsd_mutex over the last svc_put() call.  Now a
thread can only exit when svc_set_num_threads() is called, and this is
always called under nfsd_mutex.  So no care is needed.

Not only is the mutex held when a thread exits now, but the svc refcount
is elevated, so the svc_put() in svc_exit_thread() will never be a final
put, so the mutex isn't even needed at this point in the code.

89d2d9fbea SUNRPC: Revert e0a912e8dd 
Flamegraph analysis showed that the cork/uncork calls consume
nearly a third of the CPU time spent in svc_tcp_sendto(). The
other two consumers are mutex lock/unlock and svc_tcp_sendmsg().

Now that svc_tcp_sendto() coalesces RPC messages properly, there
is no need to introduce artificial delays to prevent sending
partial messages.

After applying this change, I measured a 1.2K read IOPS increase
for 8KB random I/O (several percent) on 56Gb IP over IB.

e18e157bb5 SUNRPC: Send RPC message on TCP with a single sock_sendmsg() call 
There is now enough infrastructure in place to combine the stream
record marker into the biovec array used to send each outgoing RPC
message on TCP. The whole message can be more efficiently sent with
a single call to sock_sendmsg() using a bio_vec iterator.

Note that this also helps with RPC-with-TLS: the TLS implementation
can now clearly see where the upper layer message boundaries are.
Before, it would send each component of the xdr_buf (record marker,
head, page payload, tail) in separate TLS records.

 "This happens to be a small one (due to summer I guess), and all
  hardening related:

   - Randomized kmalloc caches, by GONG, Ruiqi.

     A new opt-in hardening feature to make heap spraying harder. It
     creates multiple (16) copies of kmalloc caches, reducing the chance
     of an attacker-controllable allocation site to land in the same
     slab as e.g. an allocation site with use-after-free vulnerability.

     The selection of the copy is derived from the allocation site
     address, including a per-boot random seed.

   - Stronger typing for hardened freelists in SLUB, by Jann Horn

     Introduces a custom type for hardened freelist entries instead of
     "void *" as those are not directly dereferencable. While reviewing
     this, I've noticed opportunities for further cleanups in that code
     and added those on top"

218a06a79d cpufreq: Support per-policy performance boost 
The boost control currently applies to the whole system.  However, users
may prefer to boost a subset of cores in order to provide prioritized
performance to workloads running on the boosted cores.

Enable per-policy boost by adding a 'boost' sysfs interface under each
policy path.  This can be found at:

	/sys/devices/system/cpu/cpufreq/policy<*>/boost

Same to the global boost switch, writing 1/0 to the per-policy 'boost'
enables/disables boost on a cpufreq policy respectively.

The user view of global and per-policy boost controls should be:

1. Enabling global boost initially enables boost on all policies, and
per-policy boost can then be enabled or disabled individually, given that
the platform does support so.

2. Disabling global boost makes the per-policy boost interface illegal.

8289d810ea thermal: core: Rework .get_trend() thermal zone callback 
Passing a struct thermal_trip pointer instead of a trip index to the
.get_trend() thermal zone callback allows one of its 2 implementations,
the thermal_get_trend() function in the ACPI thermal driver, to be
simplified quite a bit, and the other implementation of it in the
ti-soc-thermal driver does not even use the relevant callback argument.

For this reason, change the .get_trend() thermal zone callback
definition and adjust the related code accordingly.

35d8dbbb25 thermal: core: Drop unused .get_trip_*() callbacks 
After recent changes in the ACPI thermal driver and in the Intel DTS
IOSF thermal driver, all thermal zone drivers are expected to use trip
tables for initialization and none of them should implement
.get_trip_type(), .get_trip_temp() or .get_trip_hyst() callbacks, so
drop these callbacks entirely from the core.

3b6bf5b1f8 spi: Updates for v6.6 
There's been quite a lot of generic activity here, but more
 administrative than featuers.  We also have a bunch of new drivers,
 including one that's part of a MFD so we pulled in the core parts of
 that:
 
  - Lots of work from both Yang Yingliang and Andy Shevchenko on moving
    to host/device/controller based terminology for devices.
  - QuadSPI SPI support for Allwinner sun6i.
  - New device support Cirrus Logic CS43L43, Longsoon, Qualcomm GENI
    QuPv3 and StarFive JH7110 QSPI.

  - Full support for dynamic allocations, following the temporary bodges

3ca9a836ff Scheduler changes for v6.6: 
- The biggest change is introduction of a new iteration of the
   SCHED_FAIR interactivity code: the EEVDF ("Earliest Eligible Virtual
   Deadline First") scheduler.
 
   EEVDF too is a virtual-time scheduler, with two parameters (weight
   and relative deadline), compared to CFS that had weight only.
   It completely reworks the base scheduler: placement, preemption,
   picking -- everything.
 
   LWN.net, as usual, has a terrific writeup about EEVDF:
 
      https://lwn.net/Articles/925371/
 
   Preemption (both tick and wakeup) is driven by testing against
   a fresh pick. Because the tree is now effectively an interval
   tree, and the selection is no longer the 'leftmost' task,
   over-scheduling is less of a problem. A lot of the CFS
   heuristics are removed or replaced by more natural latency-space
   parameters & constructs.
 
   In terms of expected performance regressions: we'll and can fix
   everything where a 'good' workload misbehaves with the new scheduler,
   but EEVDF inevitably changes workload scheduling in a binary fashion,
   hopefully for the better in the overwhelming majority of cases,
   but in some cases it won't, especially in adversarial loads that
   got lucky with the previous code, such as some variants of hackbench.
   We are trying hard to err on the side of fixing all performance
   regressions, but we expect some inevitable post-release iterations
   of that process.
 
 - Improve load-balancing on hybrid x86 systems: enable cluster
   scheduling (again).
 
 - Improve & fix bandwidth-scheduling on nohz systems.
 
 - Improve bandwidth-throttling.
 
 - Use lock guards to simplify and de-goto-ify control flow.
 
 - Misc improvements, cleanups and fixes.
