Ok, that doesn't sound entirely unlikely, but considering that you're nervous about the bisection, please just try to revert it and see if that fixes your testcase. You'll obviously need to revert the commit that removes vmtruncate_range() too, since reverting 3f31d07571ee will re-introduce the use of it (it's the next one: 17cf28afea2a1112f240a3a2da8af883be024811), but it looks like those two commits revert cleanly and the end result seems to compile ok.
