Pull irq updates from Thomas Gleixner:
 "Updates for the interrupt subsystem:

  Treewide:

    - Cleanup of setup_irq() which is not longer required because the
      memory allocator is available early.

      Most cleanup changes come through the various maintainer trees, so
      the final removal of setup_irq() is postponed towards the end of
      the merge window.

  Core:

    - Protection against unsafe invocation of interrupt handlers and
      unsafe interrupt injection including a fixup of the offending
      PCI/AER error injection mechanism.

      Invoking interrupt handlers from arbitrary contexts, i.e. outside
      of an actual interrupt, can cause inconsistent state on the
      fragile x86 interrupt affinity changing hardware trainwreck.

  Drivers:

    - Second wave of support for the new ARM GICv4.1

    - Multi-instance support for Xilinx and PLIC interrupt controllers

    - CPU-Hotplug support for PLIC

    - The obligatory new driver for X1000 TCU

    - Enhancements, cleanups and fixes all over the place"

There's a semantic conflict in the Octeon staging network driver, which
used the skb_reset_tc() function to reset skb state when re-using an
skb.  But that inline helper function was removed in mainline by commit
2c64605b ("net: Fix CONFIG_NET_CLS_ACT=n and
CONFIG_NFT_FWD_NETDEV={y, m} build").

Fix it by using skb_reset_redirect() instead.  Also move it out of the

This code path only ends up triggering if REUSE_SKBUFFS_WITHOUT_FREE is
enabled, which in turn only happens if you don't have CONFIG_NETFILTER
configured.  Which was how this wasn't caught by the usual allmodconfig

Pull scheduler updates from Ingo Molnar:
 "The main changes in this cycle are:

   - Various NUMA scheduling updates: harmonize the load-balancer and
     NUMA placement logic to not work against each other. The intended
     result is better locality, better utilization and fewer migrations.

   - Introduce Thermal Pressure tracking and optimizations, to improve
     task placement on thermally overloaded systems.

   - Implement frequency invariant scheduler accounting on (some) x86
     CPUs. This is done by observing and sampling the 'recent' CPU
     frequency average at ~tick boundaries. The CPU provides this data
     via the APERF/MPERF MSRs. This hopefully makes our capacity
     estimates more precise and keeps tasks on the same CPU better even
     if it might seem overloaded at a lower momentary frequency. (As
     usual, turbo mode is a complication that we resolve by observing
     the maximum frequency and renormalizing to it.)

   - Add asymmetric CPU capacity wakeup scan to improve capacity
     utilization on asymmetric topologies. (big.LITTLE systems)

   - PSI fixes and optimizations.

   - RT scheduling capacity awareness fixes & improvements.

   - Optimize the CONFIG_RT_GROUP_SCHED constraints code.

   - Misc fixes, cleanups and optimizations - see the changelog for
     details"

Pull locking updates from Ingo Molnar:
 "The main changes in this cycle were:

   - Continued user-access cleanups in the futex code.

   - percpu-rwsem rewrite that uses its own waitqueue and atomic_t
     instead of an embedded rwsem. This addresses a couple of
     weaknesses, but the primary motivation was complications on the -rt
     kernel.

   - Introduce raw lock nesting detection on lockdep
     (CONFIG_PROVE_RAW_LOCK_NESTING=y), document the raw_lock vs. normal
     lock differences. This too originates from -rt.

   - Reuse lockdep zapped chain_hlocks entries, to conserve RAM

Pull EFI updates from Ingo Molnar:
 "The EFI changes in this cycle are much larger than usual, for two
  (positive) reasons:

   - The GRUB project is showing signs of life again, resulting in the
     introduction of the generic Linux/UEFI boot protocol, instead of
     x86 specific hacks which are increasingly difficult to maintain.
     There's hope that all future extensions will now go through that
     boot protocol.

   - Preparatory work for RISC-V EFI support.

  The main changes are:

   - Boot time GDT handling changes

   - Simplify handling of EFI properties table on arm64

   - Generic EFI stub cleanups, to improve command line handling, file
     I/O, memory allocation, etc.

   - Introduce a generic initrd loading method based on calling back
     into the firmware, instead of relying on the x86 EFI handover
     protocol or device tree.

   - Introduce a mixed mode boot method that does not rely on the x86
     EFI handover protocol either, and could potentially be adopted by
     other architectures (if another one ever surfaces where one
     execution mode is a superset of another)

   - Clean up the contents of 'struct efi', and move out everything that
     doesn't need to be stored there.

   - Incorporate support for UEFI spec v2.8A changes that permit
     firmware implementations to return EFI_UNSUPPORTED from UEFI
     runtime services at OS runtime, and expose a mask of which ones are
     supported or unsupported via a configuration table.

   - Partial fix for the lack of by-VA cache maintenance in the
     decompressor on 32-bit ARM.

   - Changes to load device firmware from EFI boot service memory
     regions

   - Various documentation updates and minor code cleanups and fixes"

Pull objtool updates from Ingo Molnar:
 "The biggest changes in this cycle were the vmlinux.o optimizations by
   Peter Zijlstra, which are preparatory and optimization work to run
   objtool against the much richer vmlinux.o object file, to perform
   new, whole-program section based logic. That work exposed a handful
   of problems with the existing code, which fixes and optimizations are
   merged here. The complete 'vmlinux.o and noinstr' work is still work
   in progress, targeted for v5.8.

  There's also assorted fixes and enhancements from Josh Poimboeuf.

  In particular I'd like to draw attention to commit 644592d3,
  which turns fatal objtool errors into failed kernel builds. This
  behavior is IMO now justified on multiple grounds (it's easy currently
  to not notice an essentially corrupted kernel build), and the commit
  has been in -next testing for several weeks, but there could still be
  build failures with old or weird toolchains. Should that be widespread
  or high profile enough then I'd suggest a quick revert, to not hold up

Pull spi and regulator updates from Mark Brown:
 "At one point in the release cycle I managed to fat finger things and
  apply some SPI fixes onto a regulator branch and merge that into the
  SPI tree, then pull in a change shared with the MTD tree moving the
  Mediatek quadspi driver over to become the Mediatek spi-nor driver in
  the SPI tree.

  This has made a mess which I only just noticed while preparing this
  and I can't see a sensible way to unpick things due to other
  subsequent merge commits especially the pull from MTD so it looks like
  the most sensible thing to do is give up and combine the two pull
  requests.

  Fortunately both subsystems were fairly quiet this cycle, the
  highlights are:

  regulator:

   - Support for Monoloithic Power Systems MP5416, MP8867 and MPS8869
     and Qualcomm PMI8994 and SMB208.

  SPI:

   - Lots of enhancements for spi-fsl-dspi, including XSPI mode support,
     from Vladimir Oltean.

   - Support for amlogic Meson G12A, IBM FSI, Mediatek spi-nor (moved
     from MTD), NXP i.MX8Mx, Rockchip PX30, RK3308 and RK3328, and
     Qualcomm Atheros AR934x/QCA95xx"

Pull staging and IIO driver updates from Greg KH:
 "Here is the big staging and IIO driver pull request for 5.7-rc1.

  We again end up deleting more code than we added here, thanks to
  finally getting rid of the old and obsolete wireless USB stuff, and
  the exfat code (which is coming in again through the vfs tree in a
  much cleaner version).

  But some code does come back, with the octeon drivers being found to
  actually be used in the wild, so those deletions are now reverted.

  Other than those major things, just loads and loads of tiny checkpatch
  cleanups all over the place, along with new IIO drivers and fixes.

  All have been in linux-next with no reported issues"
