Pull remoteproc updates from Bjorn Andersson:
 "This introduces a new "detached" state for remote processors that are
  deemed to be running at the time Linux boots and the infrastructure
  for "attaching" to these. It then introduces the support for
  performing this operation for the STM32 platform.

  The coredump functionality is moved out from the core file and gains
  support for an optional mode where the recovery phase awaits the
  notification from devcoredump that the dump should be released. This
  allows userspace to grab the coredump in scenarios where vmalloc space
  is too low for creating a complete copy of the coredump before handing
  this to devcoredump.

  A new character device based interface is introduced to allow tying
  the stoppage of a remote processor to the termination of a user space
  process. This is useful in situations when such process provides
  crucial resources/operations for the firmware running on the remote
  processor.

  The Texas Instrument K3 driver gains support for the C66x and C71x
  DSPs.

  Qualcomm remoteprocs gains support for stashing relocation information
  in IMEM, to aid post mortem debugging and the crash notification
  mechanism is generalized to be reusable in cases where loosely coupled
  drivers needs to know about the status of a remote processor. One such
  example is the IPA hardware block, which is jointly owned with the
  modem and migrated to this improved interface.

  It also introduces a number of bug fixes and debug improvements for
  the Qualcomm modem remoteproc driver.

Update the zonefs documentation to reflect the difference between a zone's
size and it's capacity.

The maximum file size in zonefs is the zones capacity, for ZBC and ZAC
based devices, which do not have a separate zone capacity, the zone
capacity is equal to the zone size.

In the zoned storage model, the sectors within a zone are typically all
writeable. With the introduction of the Zoned Namespace (ZNS) Command
Set in the NVM Express organization, the model was extended to have a
specific writeable capacity.

This zone capacity can be less than the overall zone size for a NVMe ZNS
device or null_blk in zoned-mode. For other ZBC/ZAC devices the zone
capacity is always equal to the zone size.

Use the zone capacity field instead from blk_zone for determining the
maximum inode size and inode blocks in zonefs.

Pull perf tools updates from Arnaldo Carvalho de Melo:
 "New features:

   - Introduce controlling how 'perf stat' and 'perf record' works via a
     control file descriptor, allowing starting with events configured
     but disabled until commands are received via the control file
     descriptor. This allows, for instance for tools such as Intel VTune
     to make further use of perf as its Linux platform driver.

   - Improve 'perf record' to to register in a perf.data file header the
     clockid used to help later correlate things like syslog files and
     perf events recorded.

   - Add basic syscall and find_next_bit benchmarks to 'perf bench'.

   - Allow using computed metrics in calculating other metrics. For
     instance:

	  {
	    .metric_expr    = "l2_rqsts.demand_data_rd_hit + l2_rqsts.pf_hit + l2_rqsts.rfo_hit",
	    .metric_name    = "DCache_L2_All_Hits",
	  },
	  {
	    .metric_expr    = "max(l2_rqsts.all_demand_data_rd - l2_rqsts.demand_data_rd_hit, 0) + l2_rqsts.pf_miss + l2_rqsts.rfo_miss",
	    .metric_name    = "DCache_L2_All_Miss",
	  },
	  {
	     .metric_expr    = "dcache_l2_all_hits + dcache_l2_all_miss",
	     .metric_name    = "DCache_L2_All",
	  }

   - Add suport for 'd_ratio', '>' and '<' operators to the expression
     resolver used in calculating metrics in 'perf stat'.

  Support for new kernel features:

   - Support TEXT_POKE and KSYMBOL_TYPE_OOL perf metadata events to cope
     with things like ftrace, trampolines, i.e. changes in the kernel
     text that gets in the way of properly decoding Intel PT hardware
     traces, for instance.

  Intel PT:

   - Add various knobs to reduce the volume of Intel PT traces by
     reducing the level of details such as decoding just some types of
     packets (e.g., FUP/TIP, PSB+), also filtering by time range.

   - Add new itrace options (log flags to the 'd' option, error flags to
     the 'e' one, etc), controlling how Intel PT is transformed into
     perf events, document some missing options (e.g., how to synthesize
     callchains).

  BPF:

   - Properly report BPF errors when parsing events.

   - Do not setup side-band events if LIBBPF is not linked, fixing a
     segfault.

  Libraries:

   - Improvements to the libtraceevent plugin mechanism.

   - Improve libtracevent support for KVM trace events SVM exit reasons.

   - Add a libtracevent plugins for decoding syscalls/sys_enter_futex
     and for tlb_flush.

   - Ensure sample_period is set libpfm4 events in 'perf test'.

   - Fixup libperf namespacing, to make sure what is in libperf has the
     perf_ namespace while what is now only in tools/perf/ doesn't use
     that prefix.

  Arch specific:

   - Improve the testing of vendor events and metrics in 'perf test'.

   - Allow no ARM CoreSight hardware tracer sink to be specified on
     command line.

   - Fix arm_spe_x recording when mixed with other perf events.

   - Add s390 idle functions 'psw_idle' and 'psw_idle_exit' to list of
     idle symbols.

   - List kernel supplied event aliases for arm64 in 'perf list'.

   - Add support for extended register capability in PowerPC 9 and 10.

   - Added nest IMC power9 metric events.

  Miscellaneous:

   - No need to setup sample_regs_intr/sample_regs_user for dummy
     events.

   - Update various copies of kernel headers, some causing perf to
     handle new syscalls, MSRs, etc.

   - Improve usage of flex and yacc, enabling warnings and addressing
     the fallout.

   - Add missing '--output' option to 'perf kmem' so that it can pass it
     along to 'perf record'.

   - 'perf probe' fixes related to adding multiple probes on the same
     address for the same event.

   - Make 'perf probe' warn if the target function is a GNU indirect
     function.

   - Remove //anon mmap events from 'perf inject jit' to fix supporting
     both using ELF files for generated functions and the perf-PID.map
     approaches"

Pull locking updates from Thomas Gleixner:
 "A set of locking fixes and updates:

   - Untangle the header spaghetti which causes build failures in
     various situations caused by the lockdep additions to seqcount to
     validate that the write side critical sections are non-preemptible.

   - The seqcount associated lock debug addons which were blocked by the
     above fallout.

     seqcount writers contrary to seqlock writers must be externally
     serialized, which usually happens via locking - except for strict
     per CPU seqcounts. As the lock is not part of the seqcount, lockdep
     cannot validate that the lock is held.

     This new debug mechanism adds the concept of associated locks.
     sequence count has now lock type variants and corresponding
     initializers which take a pointer to the associated lock used for
     writer serialization. If lockdep is enabled the pointer is stored
     and write_seqcount_begin() has a lockdep assertion to validate that
     the lock is held.

     Aside of the type and the initializer no other code changes are
     required at the seqcount usage sites. The rest of the seqcount API
     is unchanged and determines the type at compile time with the help
     of _Generic which is possible now that the minimal GCC version has
     been moved up.

     Adding this lockdep coverage unearthed a handful of seqcount bugs
     which have been addressed already independent of this.

     While generally useful this comes with a Trojan Horse twist: On RT
     kernels the write side critical section can become preemtible if
     the writers are serialized by an associated lock, which leads to
     the well known reader preempts writer livelock. RT prevents this by
     storing the associated lock pointer independent of lockdep in the
     seqcount and changing the reader side to block on the lock when a
     reader detects that a writer is in the write side critical section.

   - Conversion of seqcount usage sites to associated types and
     initializers"

 "In this round, we've added two small interfaces: (a) GC_URGENT_LOW
  mode for performance and (b) F2FS_IOC_SEC_TRIM_FILE ioctl for
  security.

  The new GC mode allows Android to run some lower priority GCs in
  background, while new ioctl discards user information without race
  condition when the account is removed.

  In addition, some patches were merged to address latency-related
  issues. We've fixed some compression-related bug fixes as well as edge
  race conditions.

  Enhancements:
   - add GC_URGENT_LOW mode in gc_urgent
   - introduce F2FS_IOC_SEC_TRIM_FILE ioctl
   - bypass racy readahead to improve read latencies
   - shrink node_write lock coverage to avoid long latency

   - fix deadlock between quota writes and checkpoint
   - remove inode eviction path in synchronous path to avoid deadlock
   - fix to wait GCed compressed page writeback

VDPA mlx5 accesses config space as native endian - this is
wrong since it's a modern device and actually uses LE.

It only supports modern guests so we could punt and
just force LE, but let's use the full virtio APIs since people
tend to copy/paste code, and this is not data path anyway.

If "offset" is non-zero then we end up copying from beyond the end of
the config because of pointer math.  We can fix this by casting the
struct to a u8 pointer.

The memory allocation failure checking for in and out is currently
checking if the pointers are valid rather than the contents of what
they point to. Hence the null check on failed memory allocations is
incorrect.  Fix this by adding the missing indirection in the check.
Also for the default case, just set the *in and *out to null as
these don't have any thing allocated to kfree. Finally remove the
redundant *in and *out check as these have been already done on each
allocation in the case statement.

 "Fix a regression from an unnoticed bisect hazard in the regset series.

  A bunch of old (aout, originally) primitives used by coredumps became
  dead code after fdpic conversion to regsets. Removal of that dead code
  had been the first commit in the followups to regset series;
  unfortunately, it happened to hide the bisect hazard on sh (extern for
  fpregs_get() had not been updated in the main series when it should
  have been; followup simply made fpregs_get() static). And without that
  followup commit this bisect hazard became breakage in the mainline"

Pull pin control updates from Linus Walleij:
 "This is the bulk of the pin control changes for the v5.9 kernel
  series:

  Core changes:

   - The GPIO patch "gpiolib: Introduce for_each_requested_gpio_in_range()
     macro" was put in an immutable branch and merged into the pinctrl
     tree as well. We see these changes also here.

   - Improved debug output for pins used as GPIO.

  New drivers:

   - Ocelot Sparx5 SoC driver.

   - Intel Emmitsburg SoC subdriver.

   - Intel Tiger Lake-H SoC subdriver.

   - Qualcomm PM660 SoC subdriver.

   - Renesas SH-PFC R8A774E1 subdriver.

  Driver improvements:

   - Linear improvement and cleanups of the Intel drivers for
     Cherryview, Lynxpoint, Baytrail etc. Improved locking among other
     things.

   - Renesas SH-PFC has added support for RPC pins, groups, and
     functions to r8a77970 and r8a77980.

   - The newere Freescale (now NXP) i.MX8 pin controllers have been
     modularized. This is driven by the Google Android GKI initiative I
     think.

   - Open drain support for pins on the Qualcomm IPQ4019.

   - The Ingenic driver can handle both edges IRQ detection.

   - A big slew of documentation fixes all over the place.

   - A few irqchip template conversions by yours truly.
