Yes, see my branch on github, I just rebased it on master this week:

Yeah, I already fixed that in june and it was pushed on my branch
dev/cleger/sse on github at that time. I also have a KVM SSE
implementation on another branch.

I'll submit Linux SSE for review next week and I'have backported the PM
notifier/ mask/unmask stuff from your branch. Whom did that work so I
can credit him with a Co-Developed-by tag ?

I did not saw any other modifications though. For GHES, this seems to be
a separate commit so I'll let that to Himanchu of course.

Thanks,

Clément
