nwhitehorn 2011-06-23 04:35:45 UTC FreeBSD src repository Modified files: sys/powerpc/ps3 ps3pic.c Log: SVN rev 223463 on 2011-06-23 04:35:45Z by nwhitehorn Use atomic operations to mask and unmask IRQs. This prevents a problem (obvious in retrospect) in which interrupts on one CPU that are temporarily masked can end up permanently masked when a handler on another CPU clobbers the interrupt mask register with an old copy. Revision Changes Path 1.3 +8 -8 src/sys/powerpc/ps3/ps3pic.c
