      It don't have enough time for reviewing patches and thus don't
want to be listed as regular LED maintainer. Nonetheless I may still
give a review from time to time.

      Pull hmm updates from Jason Gunthorpe:
 "Ralph has been working on nouveau's use of hmm_range_fault() and
  migrate_vma() which resulted in this small series. It adds reporting
  of the page table order from hmm_range_fault() and some optimization
  of migrate_vma():

   - Report the size of the page table mapping out of hmm_range_fault().

     This makes it easier to establish a large/huge/etc mapping in the
     device's page table.

   - Allow devices to ignore the invalidations during migration in cases
     where the migration is not going to change pages.

     For instance migrating pages to a device does not require the
     device to invalidate pages already in the device.

   - Update nouveau and hmm_tests to use the above"

      Pull GPIO updates from Linus Walleij:
 "This is the bulk of GPIO changes for the v5.9 kernel cycle.

  There is nothing too exciting in it, but a new macro that fixes a
  build failure on a minor ARM32 platform that appeared yesterday is
  part of it so we better merge it.

  Core changes:

   - Introduce the for_each_requested_gpio() macro to help in dependent
     code all over the place. Also patch a few locations to use it while
     we are at it.

   - Split out the sysfs code into its own file.

   - Split out the character device code into its own file, then make a
     set of refactorings and improvements to this code. We are setting
     the stage to revamp the userspace API a bit in the next cycle.

   - Fix a whole slew of kerneldoc that was wrong or missing.

  New drivers:

   - The PCA953x driver now supports the PCAL9535.

  Driver improvements:

   - A host of incremental modernizations and improvements to the
     PCA953x driver.

   - Incremental improvements to the Xilinx Zynq driver.

   - Some improvements to the GPIO aggregator driver.

   - I ran all over the place switching all threaded and other drivers
     requesting their own IRQ while using the core GPIO IRQ helpers to
     pass the GPIO irq chip as a template instead of calling the
     explicit set-up functions. Next merge window we may retire the old
     code altogether"

      On architectures defining _HAVE_ARCH_IPV6_CSUM, we get
csum_ipv6_magic() defined by means of arch checksum.h headers. On
other architectures, we actually need to include net/ip6_checksum.h
to be able to use it.

Without this include, building with defconfig breaks at least for
s390.

      selftests/net: relax cpu affinity requirement in msg_zerocopy test · 16f6458f
      Willem de Bruijn authored 
      The msg_zerocopy test pins the sender and receiver threads to separate
cores to reduce variance between runs.

But it hardcodes the cores and skips core 0, so it fails on machines
with the selected cores offline, or simply fewer cores.

The test mainly gives code coverage in automated runs. The throughput
of zerocopy ('-z') and non-zerocopy runs is logged for manual
inspection.

Continue even when sched_setaffinity fails. Just log to warn anyone
interpreting the data.

selftests: rtnetlink: Fix for false-negative return values

This patchset will address the false-negative return value issue
caused by the following:
  1. The return value "ret" in this script will be reset to 0 from
     the beginning of each sub-test in rtnetlink.sh, therefore this
     rtnetlink test will always pass if the last sub-test has passed.
  2. The test result from two sub-tests in kci_test_encap() were not
     being processed, thus they will not affect the final test result
     of this test.

      kci_test_encap() is actually composed by two different sub-tests,
