Subject: Re: [patch 00/15] x86/tlb: Unexport per-CPU tlbstate

Just looking over some exports at the end of the series (and thus
ignoring bisection issues):

 - Is there any good reason to keep __flush_tlb_all inline vs moving it
   out of line and kill the flush_tlb_local and flush_tlb_global exports.
   Also there is just a single modular users in SVM, I wonder if there is
   any way to get rid of that one as well.

Also I think cpu_tlbstate itself could be marked static in tlb.c with
a few more changes, I wonder if would be worth it?
