linux-toradex.git/arch/x86/lib/cmpxchg.c, branch v3.4.78 Linux kernel for Apalis and Colibri modules x86, asm: Merge cmpxchg_486_u64() and cmpxchg8b_emu() 2010-07-29T00:05:11+00:00 H. Peter Anvin hpa@linux.intel.com 2010-07-29T00:05:11+00:00 a378d9338e8dde78314b3a6ae003de351936c729 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.
