Note, patch 12 "treewide: convert rdmsrq() from a macro to an inline function"
is going to conflict with the KVM changes for 7.3; kvm_access_xstate_msr() is
getting moved from x86.c to msrs.c.  Somewhat surprisingly, AFAICT that's the
only conflict with KVM's code movement, so it's probably not strictly required
to send a new version after the KVM pull request?
