x86: Fix ASM_X86__ header guards Change header guards named "ASM_X86__*" to "_ASM_X86_*" since: a. the double underscore is ugly and pointless. b. no leading underscore violates namespace constraints. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

x86: create asm/cmpxchg.h i386: Rearrange the cmpxchg code to allow atomic.h to get it without needing to include system.h. This kills warnings in the UML build from atomic.h about implicit declarations of cmpxchg symbols. The i386 build presumably isn't seeing this because a separate inclusion of system.h is covering it over. The cmpxchg stuff is moved to asm-i386/cmpxchg.h, with an include left in system.h for the benefit of generic code which expects cmpxchg there. Meanwhile, atomic.h includes cmpxchg.h. This causes no noticable damage to the i386 build. x86_64: Move cmpxchg into its own header. atomic.h already included system.h, so this is changed to include cmpxchg.h. This is purely cleanup - it's not fixing any warnings - so if the x86_64 system.h isn't considered as cleanup-worthy as i386, then this can be dropped. It causes no noticable damage to the x86_64 build. uml: The i386 and x86_64 cmpxchg patches require an asm-um/cmpxchg.h for the UML build.

x86: unify paravirt parts of system.h This patch moves the i386 control registers manipulation functions, wbinvd, and clts functions to system.h. They are essentially the same as in x86_64. With this, system.h paravirt comes for free in x86_64.

[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>
