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
