File/code movement. Cleaned up and queued for 4.19-4.4.
I don't know what happened here, but you've ended up adding the
entirety of arch/x86/kvm/vmx/vmx.c on all those branches rather than
applying the change to the right file.
Ugh, sorry. I think that I got confused here by 'git cherry-pick'
creating the file when it doesn't exist and it doesn't find the right
file renames.
