Revision 15bbc1b28ff65767922f78c266821cc138b90a47 authored by Marc Zyngier on 17 April 2013, 19:09:09 UTC, committed by Linus Torvalds on 17 April 2013, 19:51:32 UTC
In the very unlikely event where a guest would be foolish enough to *read* from a write-only cache maintainance register, we end up with preemption disabled, due to a misplaced get_cpu(). Just move the "is_write" test outside of the critical section.
