Linux-2.6.12-rc2 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!

doc: Add load/store guarantees to Documentation/atomic-ops.txt An IRC discussion uncovered many conflicting opinions on what types of data may be atomically loaded and stored. This commit therefore calls this out the official set: pointers, longs, ints, and chars (but not shorts). This commit also gives some examples of compiler mischief that can thwart atomicity. Please note that this discussion is relevant to !SMP kernels if CONFIG_PREEMPT=y: preemption can cause almost as much trouble as can SMP. Signed-off-by: Paul E.

Linux-2.6.12-rc2 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.

locking/atomics, cmpxchg: Privatize the inclusion of asm/cmpxchg.h After commit: 654672d4ba1a ("locking/atomics: Add _{acquire|release|relaxed}() variants of some atomic operations") Architectures may only provide {cmp,}xchg_relaxed definitions in asm/cmpxchg.h. Other variants, such as {cmp,}xchg, may be built in linux/atomic.h, which means simply including asm/cmpxchg.h may not get the definitions of all the{cmp,}xchg variants. Therefore, we should privatize the inclusions of asm/cmpxchg.h to keep it only included in arch/* and replace the inclusions outside with linux/atomic.h Signed-off-by: Boqun Feng <boqun.feng@gmail.com> Signed-off-by: Peter Zijlstra (Intel) <peterz@infradead.org> Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: Will Deacon <will.deacon@arm.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Aybuke Ozdemir <aybuke.147@gmail.com> Cc: Chris Brannon <chris@the-brannons.com> Cc: Davidlohr Bueso <dave@stgolabs.net> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Cc: Jonathan Corbet <corbet@lwn.net> Cc: Kirk Reiser <kirk@reisers.ca> Cc: Kishon Vijay Abraham I <kishon@ti.com> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Paul E.
