  kernel: Fix sparse warning for ACCESS_ONCE (2015-01-19 14:15:00 +0100)

----------------------------------------------------------------
Tighten rules for ACCESS_ONCE

This series tightens the rules for ACCESS_ONCE to only work
on scalar types. It also contains the necessary fixups as
indicated by build bots of linux-next.
Now everything is in place to prevent new non-scalar users
of ACCESS_ONCE and we can continue to convert code to
READ_ONCE/WRITE_ONCE.

----------------------------------------------------------------
Christian Borntraeger (7):
      ppc/kvm: Replace ACCESS_ONCE with READ_ONCE
      ppc/hugetlbfs: Replace ACCESS_ONCE with READ_ONCE
      x86/xen/p2m: Replace ACCESS_ONCE with READ_ONCE
      x86/spinlock: Leftover conversion ACCESS_ONCE->READ_ONCE
      mm/gup: Replace ACCESS_ONCE with READ_ONCE
      kernel: tighten rules for ACCESS ONCE
      kernel: Fix sparse warning for ACCESS_ONCE

Guenter Roeck (1):
      next: sh: Fix compile error
