Subject: KVM: expose async pf through our standard mechanism
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=3291892450e670c4f170e271cd0c4b63d5a8e41a;p=linux-beck.git

KVM: expose async pf through our standard mechanism

As Avi recently mentioned, the new standard mechanism for exposing features
is KVM_GET_SUPPORTED_CPUID, not spamming CAPs. For some reason async pf
missed that.

So expose async_pf here.
