Subject: scripts/checkpatch.pl: __GFP_NOFAIL isn't going away
Revert 7e4915e78992eb ("checkpatch: add warning of future __GFP_NOFAIL use").
There are no plans to remove __GFP_NOFAIL.
__GFP_NOFAIL exists to
a) centralise the retry-allocation-for-ever operation into the core
allocator, which is the appropriate implementation site and
b) permit us to identify code sites which aren't handling memory
exhaustion appropriately.
