2006-10-05[PATCH] i386: fix rwsem build bug on CONFIG_M386=yIngo Molnar
CONFIG_M386 turns on spinlock-based generic rwsems - which surprises the semaphore.S rwsem stubs. Tested both with and without CONFIG_M386.

2006-09-26[PATCH] i386: Remove lock section support in rwsem.hAndi Kleen
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. Cc: jbeulich@novell.com Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26[PATCH] i386: Redo semaphore and rwlock assembly helpersAndi Kleen
- 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.
