Refactor the KVM code to use the __tlbi macros, which will allow an errata
workaround that repeats tlbi dsb sequences to only change one location.
This is not intended to change the generated assembly and comparing before
and after vmlinux objdump shows no functional changes.

Thanks, I'll queue this one via arm64.

I just noticed this patch but there's been a similar patch from Mark
that I've been carrying as part of the KVM TLB monitoring series[0].

Well I've already queued the one from Christopher. It's weird that Mark's
version appears to miss the local VMID case (but it does have the
flush_icache_all I wanted :).

Anyway, I'm not reverting anything, so you'll need to rebase when this
lot lands in mainline.

Sure. I'll drop the patch the next time around.

The patch is unrelated to that series and should've gone in when
we introduced the __tlbi() macro but got left out somehow.
