2006-09-26	[PATCH] Clean up spin/rwlocks	Andi Kleen	1	-13/+1
	- Inline spinlock strings into their inline functions - Convert macros to typesafe inlines - Replace some leftover __asm__ __volatile__s with asm volatile Signed-off-by: Andi Kleen <ak@suse.de>
2006-09-26	[PATCH] Clean up read write lock assembly	Andi Kleen	1	-58/+10
	- Move the slow path fallbacks to their own assembly files This makes them much easier to read and is needed for the next change. - Add CFI annotations for unwinding (XXX need review) - Remove constant case which can never happen with out of line spinlocks - Use patchable LOCK prefixes - Don't use lock sections anymore for inline code because they can't be expressed by the unwinder (this adds one taken jump to the lock fast path) Cc: jbeulich@novell.com Signed-off-by: Andi Kleen <ak@suse.de>
2006-06-26	[PATCH] x86_64: x86_64 version of the smp alternative patch.	Gerd Hoffmann	1	-4/+4
	Changes are largely identical to the i386 version: * alternative #define are moved to the new alternative.h file. * one new elf section with pointers to the lock prefixes which can be nop'ed out for non-smp. * two new elf sections simliar to the "classic" alternatives to replace SMP code with simpler UP code. * fixup headers to use alternative.h instead of defining their own LOCK / LOCK_PREFIX macros. The patch reuses the i386 version of the alternatives code to avoid code duplication. The code in alternatives.c was shuffled around a bit to reduce the number of #ifdefs needed. It also got some tweaks needed for x86_64 (vsyscall page handling) and new features (noreplacement option which was x86_64 only up to now). Debug printk's are changed from compile-time to runtime.

2005-12-24	[PATCH] Fix typo in x86_64 __build_write_lock_const assembly	Ben Collins	1	-1/+1
	Based on __build_read_lock_const, this looked like a bug. [ Indeed. Maybe nobody uses this version? Worth fixing up anyway ] Signed-off-by: Linus Torvalds <torvalds@osdl.org>
2005-04-16	Linux-2.6.12-rc2	Linus Torvalds	1	-0/+86
	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!
