Not quite. On its own, this doesn't fix anything in KVM. It simply plugs
a deficiency in the arm64 kexec implementation. If you want to be
completely true to the content of the patch, it should read:
"arm64: KVM: Allow EL2 context to be reset on shutdown"
Can we now drop the blame game and get back to the actual code?
Thanks,
