KVM: Let host know whether the guest can handle async PF in non-userspace context.

2011-01-12T09:23:21+00:00

If guest can detect that it runs in non-preemptable context it can
handle async PFs at any time, so let host know that it can send async
PF even if guest cpu is not in userspace.

KVM: PPC: Add mtsrin PV code

2010-10-24T08:52:12+00:00

This is the guest side of the mtsr acceleration. Using this a guest can now
call mtsrin with almost no overhead as long as it ensures that it only uses
it with (MSR_IR|MSR_DR) == 0. Linux does that, so we're good.
