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!

[PATCH] FRV: Use the correct preemption primitives in kmap_atomic() and co Use inc/dec_preempt_count() rather than preempt_enable/disable() and manually add in the compiler barriers that were provided by the latter. This makes FRV consistent with other archs. Furthermore, the compiler barrier effects are now there unconditionally - at least as far as preemption is concerned - because we don't want the compiler moving memory accesses out of the section of code in which the mapping is in force - in effect the kmap_atomic() must imply a LOCK-class barrier and the kunmap_atomic() must imply an UNLOCK-class barrier to the compiler.

[PATCH] mm: pagefault_{disable,enable}() Introduce pagefault_{disable,enable}() and use these where previously we did manual preempt increments/decrements to make the pagefault handler do the atomic thing. Currently they still rely on the increased preempt count, but do not rely on the disabled preemption, this might go away in the future. (NOTE: the extra barrier() in pagefault_disable might fix some holes on machines which have too many registers for their own good) [heiko.carstens@de.ibm.com: s390 fix] Signed-off-by: Peter Zijlstra <a.p.zijlstra@chello.nl> Acked-by: Nick Piggin <npiggin@suse.de> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
