2010-08-18Make do_execve() take a const filename pointerDavid Howells1-3/+7
Make do_execve() take a const filename pointer so that kernel_execve() compiles correctly on ARM: arch/arm/kernel/sys_arm.c:88: warning: passing argument 1 of 'do_execve' discards qualifiers from pointer target type This also requires the argv and envp arguments to be consted twice, once for the pointer array and once for the strings the array points to. This is because do_execve() passes a pointer to the filename (now const) to copy_strings_kernel(). A simpler alternative would be to cast the filename pointer in do_execve() when it's passed to copy_strings_kernel(). do_execve() may not change any of the strings it is passed as part of the argv or envp lists as they are some of them in .rodata, so marking these strings as const should be fine. Further kernel_execve() and sys_execve() need to be changed to match. This has been test built on x86_64, frv, arm and mips.

2010-08-17of: Fix missing includesGrant Likely2-1/+3
This patch fixes missing includes from a number of .c files because the code (wrongfully) depended on prom.h including them. The include of linux/of_address.h was removed in microblaze prom.h in commit "of/address: Clean up function declarations" (sha1 id 22ae782f8), but not fixed in some callers. This patch fixes them up.

2010-08-11dma-mapping: remove dma_is_consistent APIFUJITA Tomonori1-1/+0
Architectures implement dma_is_consistent() in different ways (some misinterpret the definition of API in DMA-API.txt). So it hasn't been so useful for drivers. We have only one user of the API in tree. Unlikely out-of-tree drivers use the API. Even if we fix dma_is_consistent() in some architectures, it doesn't look useful at all. It was invented long ago for some old systems that can't allocate coherent memory at all. It's better to export only APIs that are definitely necessary for drivers. Let's remove this API.

2010-08-11dma-mapping: unify dma_get_cache_alignment implementationsFUJITA Tomonori1-5/+0
dma_get_cache_alignment returns the minimum DMA alignment. Architectures defines it as ARCH_DMA_MINALIGN (formally ARCH_KMALLOC_MINALIGN). So we can unify dma_get_cache_alignment implementations. Note that some architectures implement dma_get_cache_alignment wrongly. dma_get_cache_alignment() should return the minimum DMA alignment. So fully-coherent architectures should return 1. This patch also fixes this issue.

2010-08-11dma-mapping: rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGNFUJITA Tomonori1-1/+1
Now each architecture has the own dma_get_cache_alignment implementation. dma_get_cache_alignment returns the minimum DMA alignment. Architectures define it as ARCH_KMALLOC_MINALIGN (it's used to make sure that malloc'ed buffer is DMA-safe; the buffer doesn't share a cache with the others). So we can unify dma_get_cache_alignment implementations. This patch: dma_get_cache_alignment() needs to know if an architecture defines ARCH_KMALLOC_MINALIGN or not (needs to know if architecture has DMA alignment restriction). However, slab.h define ARCH_KMALLOC_MINALIGN if architectures doesn't define it. Let's rename ARCH_KMALLOC_MINALIGN to ARCH_DMA_MINALIGN. ARCH_KMALLOC_MINALIGN is used only in the internals of slab/slob/slub (except for crypto).
