The current kvm implementation keeps EL2 vector table installed even when the system is shut down. This prevents kexec from putting the system with kvm back into EL2 when starting a new kernel.

This is a kvm bug fix, so I think the subject should be something like 'arm64/kvm: Fix shutdown issue'.

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,
