Module Name: src Committed By: matt Date: Fri May 25 12:32:49 UTC 2012
Modified Files: src/sys/arch/vax/include: types.h userret.h Log Message: Implement __HAVE_RAS. Unlike most implementation, this is done in userret instead of cpu_switchto since we already accessing the proc structure so the additional overhead of check p_raslist is minimal.
