The conflict is trivial, no worries. But as I was resolving it, I
looked at that PASID_DISABLED define..

That too seems to be stale and unused since commit 9bfecd058339
("x86/cpufeatures: Force disable X86_FEATURE_ENQCMD and remove
update_pasid()")

I left it alone because I didn't want to do any extra development in
the merge commit itself, but it looks to me like there's some room for
more cleanips. No?
