2006-12-07[PATCH] lockdep: name some old style locksPeter Zijlstra
Name some of the remaning 'old_style_spin_init' locks Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
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>
2006-07-08i386: improve and correct inline asm memory constraintsLinus Torvalds
Use "+m" rather than a combination of "=m" and "m" for improved clarity and consistency. This also fixes some inlines that incorrectly didn't tell the compiler that they read the old value at all, potentially causing the compiler to generate bogus code. It appear that all of those potential bugs were hidden by the use of extra "volatile" specifiers on the data structures in question, though. Signed-off-by: Linus Torvalds <torvalds@osdl.org>

2005-10-29[PATCH] add sem_is_read/write_locked()Rik Van Riel
Add sem_is_read/write_locked functions to the read/write semaphores, along the same lines of the *_is_locked spinlock functions. The swap token tuning patch uses sem_is_read_locked; sem_is_write_locked is added for completeness.

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!
