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.
