Subject: linux-next: build failure after merge of the kvm tree

Hi all,

After merging the kvm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

Caused by commits

  1561fcbc8e16 ("KVM: x86: Explicitly #define the VCPU_REGS_* indices")
  a46e726511f4 ("KVM: VMX: Move vCPU-run code to a proper assembly routine")

It looks like a file was not git added :-(

I have used the kvm tree from next-20190215 for today.
