Subject: KVM: SVM: set IRR in svm_deliver_interrupt
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=30811174f0dbe17fd58eba5c22c50292c083c75b;p=linux.git

KVM: SVM: set IRR in svm_deliver_interrupt

SVM has to set IRR for both the AVIC and the software-LAPIC case,
so pull it up to the common function that handles both configurations.
