[POWERPC] Use ARRAY_SIZE macro when appropriate

2007-02-08T05:08:18+00:00

Use ARRAY_SIZE macro already defined in linux/kernel.h Signed-off-by: Ahmed S. Darwish Cc: Benjamin Herrenschmidt Signed-off-by: Andrew Morton Signed-off-by: Paul Mackerras

[POWERPC] Added kprobes support to ppc32

2007-02-07T04:55:19+00:00

Added kprobes to ppc32 platforms that have use single_step_exception. This excludes 4xx and anything Book-E since their debug mechanisms for single stepping are completely different. Signed-off-by: Kumar Gala

[POWERPC] Fix array indexing error in rheap grow()

2007-02-07T03:03:19+00:00

The grow() function in the rheap library allocates a larger array of blocks, copies the contents of the old blocks array to the newly allocated array and fixes the list_head pointers after the copy. At the end, the new blocks must be enqueued to the empty_list of the rh_info_t structure. This patch fixes a bug where the code was indexing past the end of the array when enqueueing blocks. The UCC ethernet driver, which uses the rheap allocator, experiences kernel panics because of this bug. Signed-off-by: Ionut Nicu Signed-off-by: Timur Tabi Signed-off-by: Paul Mackerras

[POWERPC] 8xx: generic 8xx code arch/powerpc port

2007-02-07T03:01:02+00:00

Including support for non-coherent cache, some mm-related things + relevant field in Kconfig and Makefiles. Also included rheap.o compilation if 8xx is defined. Non-coherent mapping were refined and renamed according to Cristoph Hellwig. Orphaned functions were cleaned up. [Also removed arch/ppc/kernel/dma-mapping.c, because otherwise compiling with ARCH=ppc for a non DMA-cache-coherent platform ends up with two copies of __dma_alloc_coherent etc. -- paulus.] Signed-off-by: Vitaly Bordug Signed-off-by: Paul Mackerras

[POWERPC] Disallow kprobes on emulate_step and branch_taken

2006-11-01T04:14:12+00:00

On powerpc, probing on emulate_step function will crash 2.6.18.1 when it is triggered. When kprobe is triggered, emulate_step() is on its kernel path and will cause recursive kprobe fault. And branch_taken() is called in emulate_step(). This disallows kprobes on both of them. Signed-off-by: Paul Mackerras

[POWERPC] Fix rheap alignment problem

2006-10-02T10:27:47+00:00

Honor alignment parameter in the rheap allocator. This is needed by qe_lib. Remove compile warning. Signed-off-by: Pantelis Antoniou Signed-off-by: Li Yang Acked-by: Kumar Galak Signed-off-by: Paul Mackerras

POWERPC: Move generic cpm2 stuff to powerpc

2006-09-21T18:18:53+00:00

This moves the cpm2 common code and PIC stuff to the powerpc. Most of the files were just copied from ppc/, with minor tuning to make it compile, and, subsequently, work. Signed-off-by: Vitaly Bordug

[POWERPC] make spinlocks work in a combined kernel

2006-09-20T04:01:16+00:00

If we build a pSeries/iSeries combined kernel, we will need this. Signed-off-by: Stephen Rothwell
