x86: rename .i assembler includes to .h .i is an ending used for preprocessed stuff. This patch therefore renames assembler include files to .h and guards the contents with an #ifdef __ASSEMBLY__. [ tglx: arch/x86 adaptation ] Signed-off-by: Adrian Bunk <bunk@kernel.org> Signed-off-by: Andi Kleen <ak@suse.de> Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

#ifdef __ASSEMBLY__
[PATCH] i386: Redo semaphore and rwlock assembly helpers - Move them to a pure assembly file. Previously they were in a C file that only consisted of inline assembly. Doing it in pure assembler is much nicer. - Add a frame.i include with FRAME/ENDFRAME macros to easily add frame pointers to assembly functions - Add dwarf2 annotation to them so that the new dwarf2 unwinder doesn't get stuck on them - Random cleanups Includes feedback from Jan Beulich and a UML build fix from Andrew Morton.
