The patch titled
KVM: Simplify test for interrupt window
has been removed from the -mm tree. Its filename was
kvm-simplify-test-for-interrupt-window.patch
This patch was dropped because it was merged into mainline or a subsystem tree
------------------------------------------------------
Subject: KVM: Simplify test for interrupt window
From: Dor Laor <dor.laor@xxxxxxxxxxxx>
No need to test for rflags.if as both VT and SVM specs assure us that on exit
caused from interrupt window opening, 'if' is set.
