[akpm]

------------------------------------------------------
Subject: mm: remove gcc workaround
From: Nick Piggin <npiggin@suse.de>

Minimum gcc version is 3.2 now.  However, with likely profiling, even
modern gcc versions cannot always eliminate the call.

Replace the placeholder functions with the more conventional empty static
inlines, which should be optimal for everyone.
