Cover letter [patch 0/4] x86/kaiser: Paravirt support and various fixlets

The series contains the following changes against

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git WIP.x86/asm

- Remove the flush_tlb_single paravirt patching. It's not longer INVPCID anymore. Especially not with KAISER enabled.

- Remove the !PARAVIRT dependency of KAISER and just disable it at boot time when the kernel runs as XEN_PV guest.

- Address a few review comments.

Thanks,

tglx
