Now, regarding the above bug, I'm afraid the only approaches I see that

specific variant of the new start/commit hooks that does the flush.

Whyever not the latter?  Jeremy seems to have gifted that to you,
for precisely such a purpose.

p.s. I surely agree with you over the name ptep_get_and_clear_full():
horrid, even more confusing than the tlb->fullmm from which it derives
its name.  I expect I'd agree with you over a lot more too, but please,
bugfixes first.
