*	x86, asm: Move cmpxchg emulation code to arch/x86/lib	H. Peter Anvin	2010-07-28	1	-72/+0
\| \| \| \| \| \| \| \| \|	Move cmpxchg emulation code from arch/x86/kernel/cpu (which is otherwise CPU identification) to arch/x86/lib, where other emulation code lives already. Signed-off-by: H.

*	x86: move cmpxchg fallbacks to a generic place	Thomas Petazzoni	2008-08-18	1	-0/+72
	arch/x86/kernel/cpu/intel.c defines a few fallback functions (cmpxchg_*()) that are used when the CPU doesn't support cmpxchg and/or cmpxchg64 natively. However, while defined in an Intel-specific file, these functions are also used for CPUs from other vendors when they don't support cmpxchg and/or cmpxchg64. This breaks the compilation when support for Intel CPUs is disabled. This patch moves these functions to a new arch/x86/kernel/cpu/cmpxchg.c file, unconditionally compiled when X86_32 is enabled.
