4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Linus Torvalds torvalds@linux-foundation.org
commit 6d53cefb18e4646fb4bf62ccb6098fb3808486df upstream.
Commit abb2ea7dfd82 ("compiler, clang: suppress warning for unused static inline functions") just caused more warnings due to re-defining the 'inline' macro.
So undef it before re-defining it, and also add the 'notrace' attribute like the gcc version that this is overriding does.
Maybe this makes clang happier.
