Impressively small and well done !

Can you please make that patch set against

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git x86-pti-for-linus

so we immediately have it backportable for 4.14 stable? It's only a trivial
conflict in pgtable.h, but we'd like to make the life of stable as simple
as possible. They have enough headache with the pre 4.14 trees.

We can pick some of the simple patches which make defines and inlines
available out of the pile right away and apply them to x86/pti to shrink
the amount of stuff you have to worry about.

Thanks,

tglx
