Your patchset fixes the issue for me (look at the attached files for
more detailed information).

I tested the "To Be Loved" (TBL VS. TLB flushes) edition against
Linux-next (next-20150204) where I had originally seen and reported
the call-trace.

Before I forget... The Fixes-tag misses pointing to Dave Hansen's...

commit d17d8f9dedb9dd76fd540a5c497101529d9eb25a
"x86/mm: Add tracepoints for TLB flushes"

My POV is that both patches somehow belong together.
If you decide to push them through two different trees, please add a
note/reference to each other.

Thanks to all involved people nailing this down.
