From: Ingo Molnar
Date: Sun Feb 28 2010 - 14:55:41 EST
The following build bug (x86, allyesconfig):
arch/x86/oprofile/built-in.o:(.data+0x250): multiple definition of `buffer_mutex'
Was triggered in -tip testing, caused by this upstream commit:
116ee77: dell-laptop: Use buffer with 32-bit physical address
There's multiple buffer_mutex's in the kernel. Make this new one
static.
