      Pull block fixes from Jens Axboe:
 "This should be it for 5.10.

  Mike and Song looked into the warning case, and thankfully it appears
  the fix was pretty trivial - we can just change the md device chunk
  type to unsigned int to get rid of it. They cannot currently be < 0,
  and nobody is checking for that either.

  We're reverting the discard changes as the corruption reports came in
  very late, and there's just no time to attempt to deal with it at this
  point. Reverting the changes in question is the right call for 5.10"

Fix this by changing the chunk_sectors member of 'struct mddev' from
int to 'unsigned int' to match the type used for the 'chunk_sectors'
member of 'struct queue_limits'.  Various MD code still uses 'int' but
none of it appears to ever make use of signed int; and storing
positive signed int in unsigned is perfectly safe.

      tools/kvm_stat: Exempt time-based counters · 111d0bda
      Stefan Raspl authored 
      The new counters halt_poll_success_ns and halt_poll_fail_ns do not count
events. Instead they provide a time, and mess up our statistics. Therefore,
we should exclude them.
Removal is currently implemented with an exempt list. If more counters like
these appear, we can think about a more general rule like excluding all
fields name "*_ns", in case that's a standing convention.

      KVM: mmu: Fix SPTE encoding of MMIO generation upper half · 34c0f6f2
      Maciej S. Szmigiero authored 
      Commit cae7ed3c ("KVM: x86: Refactor the MMIO SPTE generation handling")
cleaned up the computation of MMIO generation SPTE masks, however it
introduced a bug how the upper part was encoded:
SPTE bits 52-61 were supposed to contain bits 10-19 of the current
generation number, however a missing shift encoded bits 1-10 there instead
(mostly duplicating the lower part of the encoded generation number that
then consisted of bits 1-9).

In the meantime, the upper part was shrunk by one bit and moved by
subsequent commits to become an upper half of the encoded generation number
(bits 9-17 of bits 0-17 encoded in a SPTE).

In addition to the above, commit 56871d44 ("KVM: x86: fix overlap between SPTE_MMIO_MASK and generation")
has changed the SPTE bit range assigned to encode the generation number and
the total number of bits encoded but did not update them in the comment
attached to their defines, nor in the KVM MMU doc.
Let's do it here, too, since it is too trivial thing to warrant a separate
commit.
