Yeah. Sorry about that. The kbuild-bot doesn't do much cross function
analysis (none for functions that are not inline). I saw that this
patch was old and could easily have checked it on my system which has
the cross function DB but I was in a rush. :/ My bad. Will try be a
more diligent person next time.

The mm devs have modified vmalloc() to all GFP_NOIO. It's only
GFP_ATOMIC and GFP_SLEEP which aren't allowed now. I have pushed an
update for this.
