Removed rheap in arch/ppc/lib and changed build system to use the one in arch/powerpc/lib. Signed-off-by: Kumar Gala

[POWERPC] Change rheap functions to use ulongs instead of pointers

2007-05-10T04:01:43Z

The rheap allocation functions return a pointer, but the actual value is based on how the heap was initialized, and so it can be anything, e.g. an offset into a buffer. A ulong is a better representation of the value returned by the allocation functions. This patch changes all of the relevant rheap functions to use a unsigned long integers instead of a pointer. In case of an error, the value returned is a negative error code that has been cast to an unsigned long. The caller can use the IS_ERR_VALUE() macro to check for this. All code which calls the rheap functions is updated accordingly. Macros IS_MURAM_ERR() and IS_DPERR(), have been deleted in favor of IS_ERR_VALUE(). Also added error checking to rh_attach_region().

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

Clean up mostly unused IOSPACE macros

2007-05-08T18:15:13Z

Most architectures defined three macros, MK_IOSPACE_PFN(), GET_IOSPACE() and GET_PFN() in pgtable.h. However, the only callers of any of these macros are in Sparc specific code, either in arch/sparc, arch/sparc64 or drivers/sbus. This patch removes the redundant macros from all architectures except sparc and sparc64. Signed-off-by: David Gibson Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

move die notifier handling to common code

2007-05-08T18:15:04Z

This patch moves the die notifier handling to common code. Previous various architectures had exactly the same code for it. Note that the new code is compiled unconditionally, this should be understood as an appel to the other architecture maintainer to implement support for it aswell (aka sprinkling a notify_die or two in the proper place) arm had a notifiy_die that did something totally different, I renamed it to arm_notify_die as part of the patch and made it static to the file it's declared and used at. avr32 used to pass slightly less information through this interface and I brought it into line with the other architectures.

[PATCH] x86: PARAVIRT: add hooks to intercept mm creation and destruction

2007-05-02T17:27:14Z

Add hooks to allow a paravirt implementation to track the lifetime of an mm. Paravirtualization requires three hooks, but only two are needed in common code. They are: arch_dup_mmap, which is called when a new mmap is created at fork arch_exit_mmap, which is called when the last process reference to an mm is dropped, which typically happens on exit and exec. The third hook is activate_mm, which is called from the arch-specific activate_mm() macro/function, and so doesn't need stub versions for other architectures. It's called when an mm is first used.
