powerpc: Remove arch/ppc and include/asm-ppc

2008-06-10T11:40:22Z

All the maintained platforms are now in arch/powerpc, so the old arch/ppc stuff can now go away.

[POWERPC] ppc: More compile fixes

2008-05-12T12:57:51Z

This fixes a few more miscellaneous compile problems with ARCH=ppc. 1. Don't compile devres.c on ARCH=ppc, it doesn't have ioremap_flags. 2. Include in setup.c for the __DO_IRQ_CANON definition. 3. Include in residual.c for the definition of create_proc_read_entry. 4. Fix xchg_ptr to be a static inline to eliminate a compiler warning. Signed-off-by: Paul Mackerras

Add cmpxchg_local to ppc

2008-02-07T16:42:32Z

Add a local processor version of cmpxchg for ppc. Implements __cmpxchg_u32_local and uses it for 32 bits cmpxchg_local. It uses the non NMI safe cmpxchg_local_generic for 1, 2 and 8 bytes cmpxchg_local.

ppc: fix AT_VECTOR_SIZE on arch/ppc

2007-10-23T02:18:54Z

Commit 4f9a58d75bfe82ab2b8ba5b8506dfb190a267834 ("increase AT_VECTOR_SIZE to terminate saved_auxv properly") changes the size of AT_VECTOR_SIZE from hard coded '44' to a calculation based on the value of AT_VECTOR_SIZE_ARCH and AT_VECTOR_SIZE_BASE. The change works for arch/powerpc, but it breaks arch/ppc because the needed AT_VECTOR_SIZE_ARCH is not present in include/asm-ppc/system.h and a default value of 0 is used instead. This results in AT_VECTOR_SIZE being too small and it causes a kernel crash on loading init. Signed-off-by: Grant Likely Signed-off-by: Linus Torvalds

[POWERPC] Fix ARCH=ppc builds

2007-07-22T11:30:58Z

The recent signal rework broke ARCH=ppc builds with the following error: CC arch/powerpc/kernel/signal.o arch/powerpc/kernel/signal.c: In function Âdo_signalÂ: arch/powerpc/kernel/signal.c:142: error: implicit declaration of function Âset_dabrÂ make[1]: *** [arch/powerpc/kernel/signal.o] Error 1 This fixes it by including a function prototype in asm-ppc/system.h.

atomic.h: atomic_add_unless as inline. Remove system.h atomic.h circular dependency

2007-05-08T18:15:20Z

atomic_add_unless as inline. Remove system.h atomic.h circular dependency. I agree (with Andi Kleen) this typeof is not needed and more error prone. All the original atomic.h code that uses cmpxchg (which includes the atomic_add_unless) uses defines instead of inline functions, probably to circumvent a circular dependency between system.h and atomic.h on powerpc (which my patch addresses). Therefore, it makes sense to use inline functions that will provide type checking. atomic_add_unless as inline. Remove system.h atomic.h circular dependency. Digging into the FRV architecture shows me that it is also affected by such a circular dependency. Here is the diff applying this against the rest of my atomic.h patches. It applies over the atomic.h standardization patches. Signed-off-by: Mathieu Desnoyers Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] remove set_wmb - arch removal

2006-07-15T04:56:14Z

set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt Signed-off-by: Linus Torvalds
