From 774400a3ba23b63f4de39e67ce6c4e48935809dc Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Mon, 18 Aug 2008 12:33:21 +0200 Subject: x86: move cmpxchg fallbacks to a generic place 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.
