Subject: KVM: SVM: leave halted state on vmexit
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=38c0b192bd6df089cdffd9828d19e764385f96e6;p=linux.git

KVM: SVM: leave halted state on vmexit

Similar to VMX, we need to leave the halted state when performing a vmexit.
Failure to do so will cause a hang after vmexit.
