KVM: SVM: Defer nmi processing until switch to host state is complete 2007-11-08T10:05:43+00:00 Avi Kivity avi@qumranet.com 2007-11-07T15:14:18+00:00 56ba47ddbd5af7918bf1acdbe3deb979d0dcd64b If we stgi() too soon, nmis can reach the processor even though interrupts are disabled, catching it in a half-switched state. Delay the stgi() until we're done switching. Signed-off-by: Avi Kivity <avi@qumranet.com>
