Re: [PATCH 1/1] arch Kconfig: remove references to IRQ_PER_CPU

Re: [PATCH 1/2] atomic: Allow atomic_inc_not_zero to be overridden
On Thu, Mar 01, 2012 at 03:02:56PM -0800, Andrew Morton wrote: Please merge this via the ppc tree? And let's ask the hexagon maintainers to take a look at the definition in arch/hexagon/include/asm/atomic.h. I assume that it can be removed, but that might cause problems with files which include asm/atomic.h directly. I have found two such files in non-arch code and have queued fixes. There are no such files in arch/hexagon code, so I think it's safe to zap the hexagon definition of atomic_inc_not_zero(). Just tested it; it's safe to zap the Hexagon definition of atomic_inc_not_zero()... I'm fine with this going in through some other tree (still getting mine set up).

[PATCH] powerpc: use rwsem.h from generic location
As of commit dd472da38, rwsem.h was moved into asm-generic.
This patch removes the arch file and points the build at
its new location.
