Linus Torvalds c833e17e27 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.
