As per request, I've published a version rebased ontop of
linux-next-20211223 here: [4].

During the rebasing, I saw that some ASM code conflicts with, I
guess, Peter's "execute past ret" mitigation.
So I would also like to ask you to give me a branch which I should
pick to base my series on top of. There's a bunch of different x86
branches, like several in peterz-queue, x86/core etc., so I got lost
a little.
The one posted yesterday was based on the mainline 5.16-rc6.
