Chris Metcalf 627ae54854 tile: use READ_ONCE() in arch_spin_is_locked() ... This avoid potential issues if callers were to loop on these routines without some kind of memory barrier. Currently there are no such users in-tree, but it seems better safe than sorry. Also, in the tilepro case we read "current" before "next", which gives us a slightly better guarantee that the lock was actually unlocked at least momentarily if we return claiming that it is not locked. None of the callers actually rely on this behavior, as far as I know, however. Signed-off-by: Chris Metcalf <cmetcalf@ezchip.com>		2015-04-28 22:43:16 -04:00
