*	x86, 386 removal: Remove CONFIG_CMPXCHG	H. Peter Anvin	2012-11-29	1	-54/+0
\| \| \| \| \| \| \| \|	All 486+ CPUs support CMPXCHG, so remove the fallback 386 support code. Signed-off-by: H. Peter Anvin <hpa@linux.intel.com> Link: http://lkml.kernel.org/r/1354132230-21854-3-git-send-email-hpa@linux.intel.com
*	x86, asm: Merge cmpxchg_486_u64() and cmpxchg8b_emu()	H. Peter Anvin	2010-07-29	1	-18/+0
\| \| \| \| \| \| \| \| \| \| \|	We have two functions for doing exactly the same thing -- emulating cmpxchg8b on 486 and older hardware -- with different calling conventions, and yet doing the same thing. Drop the C version and use the assembly version, via alternatives, for both the local and non-local versions of cmpxchg8b. Signed-off-by: H.

*	x86, asm: Move cmpxchg emulation code to arch/x86/lib	H. Peter Anvin	2010-07-29	1	-0/+72
	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. Peter Anvin <hpa@linux.intel.com> LKML-Reference: <AANLkTikAmaDPji-TVDarmG1yD=fwbffcsmEU=YEuP+8r@mail.gmail.com>
