[PATCH] x86_64: Fix VSMP build
Patch fixes a build problem with CONFIG_X86_VSMP. The vSMP bits probably gathered some fuzz on its way to mainline, and safe_halt() which was outside the #endif (CONFIG_X86_VSMP) somehow got inside the !CONFIG_X86_VSMP condition, hence being undefined and breaking CONFIG_X86_VSMP builds. Patch takes safe_halt() and halt() macros out of the #endif Signed-off-by: Ravikiran Thirumalai <kiran@scalex86.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
