Subject: [PATCH] make GFP_NOTRACK flag unconditional

There was a general sentiment in a recent discussion (See
https://lkml.org/lkml/2012/9/18/258) that the __GFP flags should be
defined unconditionally. Currently, the only offender is GFP_NOTRACK,
which is conditional to KMEMCHECK.

This simple patch makes it unconditional.
