Ingo Molnar	88271e9e43	[PATCH] i386: fix rwsem build bug on CONFIG_M386=y ... CONFIG_M386 turns on spinlock-based generic rwsems - which surprises the semaphore.S rwsem stubs. Tested both with and without CONFIG_M386.

Dave Jones	038b0a6d8d	Remove all inclusions of <linux/config.h> ... kbuild explicitly includes this at build time. Signed-off-by: Dave Jones <davej@redhat.com>	2006-10-04 03:38:54 -04:00
Andi Kleen	add659bf8a	[PATCH] i386: Remove lock section support in rwsem.h ... Lock sections don't work the new dwarf2 unwinder This generates slightly smaller code. It adds one more taken jump to the fast path. Also move the trampolines into semaphore.S and add proper CFI annotations.

Andi Kleen	ecaf45ee5c	[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.
