So __GFP_COMP is actually problematic and changes behavior, and I plan to lift an optimization from the arm code to the generic one that only rounds up allocations to the next page size instead of the next power of two, so I need this check now. Other flags including GFP_USER are pretty bogus to, but I actually need to do a full audit before rejecting them, which I've only done for GFP_COMP so far.
