All the questions from me were answered and I don't have any
other comment/question for the latest patch (assuming that
the patch will be updated based on the comment from Tom).

FYI.
I was going to ask you a question about x86_spec_ctrl_mask.
But, since it is used only for KVM (although x86_spec_ctrl_mask
is defined/used only in arch/x86/kernel/cpu/bugs.c),
I plan to ask you about it once your KVM patch gets updated
rather than this patch.

Thanks,
Reiji
