The patch titled
KVM: AMD SVM: Avoid three more new instructions
has been removed from the -mm tree. Its filename was
kvm-amd-svm-implementation-avoid-three-more-new-instructions.patch
This patch was dropped because it was folded into kvm-userspace-interface.patch
------------------------------------------------------
Subject: KVM: AMD SVM: Avoid three more new instructions
From: Avi Kivity <avi@xxxxxxxxxxxx>
The clgi, stgi, and invlpga instructions are all too new to unleash on
the world's assemblers. Replace them with the opcode sequences.
