[PATCH] arch/arm26/kernel/entry.S: remove dead code

2007-03-01T22:53:35+00:00

CONFIG_ALIGNMENT_TRAP is never set on arm26. Signed-off-by: Adrian Bunk Acked-by: Ian Molton Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Dynamic kernel command-line: arm26

2007-02-12T17:48:37+00:00

1. Rename saved_command_line into boot_command_line. 2. Set command_line as __initdata. Signed-off-by: Alon Bar-Lev Cc: Ian Molton Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Consolidate default sched_clock()

[PATCH] disable init/initramfs.c: architectures

2007-02-11T18:51:25+00:00

Update all arch/*/kernel/vmlinux.lds.S to not include space for initramfs when CONFIG_BLK_DEV_INITRAMFS is not selected. This saves another 4 kbytes on most platfoms (some reserve PAGE_SIZE for initramfs). Signed-off-by: Jean-Paul Saman Cc: Al Viro Cc: Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] ARM26: Use ARRAY_SIZE macro when appropriate

2007-02-11T18:51:19+00:00

Use ARRAY_SIZE macro already defined in linux/kernel.h Signed-off-by: Ahmed S. Darwish Acked-by: Ian Molton Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] Set CONFIG_ZONE_DMA for arches with GENERIC_ISA_DMA

2007-02-11T18:51:19+00:00

As Andi pointed out: CONFIG_GENERIC_ISA_DMA only disables the ISA DMA channel management. Other functionality may still expect GFP_DMA to provide memory below 16M. So we need to make sure that CONFIG_ZONE_DMA is set independent of CONFIG_GENERIC_ISA_DMA. Undo the modifications to mm/Kconfig where we made ZONE_DMA dependent on GENERIC_ISA_DMA and set theses explicitly in each arches Kconfig. Reviews must occur for each arch in order to determine if ZONE_DMA can be switched off. It can only be switched off if we know that all devices supported by a platform are capable of performing DMA transfers to all of memory (Some arches already support this: uml, avr32, sh sh64, parisc and IA64/Altix). In order to switch ZONE_DMA off conditionally, one would have to establish a scheme by which one can assure that no drivers are enabled that are only capable of doing I/O to a part of memory, or one needs to provide an alternate means of performing an allocation from a specific range of memory (like provided by alloc_pages_range()) and insure that all drivers use that call. In that case the arches alloc_dma_coherent() may need to be modified to call alloc_pages_range() instead of relying on GFP_DMA.

[PATCH] getting rid of all casts of k[cmz]alloc() calls

2006-12-13T17:05:58+00:00

Run this: #!/bin/sh for f in $(grep -Erl "$[^$]*\) *k[cmz]alloc" *) ; do echo "De-casting $f..." perl -pi -e "s/ ?= ?$[^$]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f done And then go through and reinstate those cases where code is casting pointers to non-pointers. And then drop a few hunks which conflicted with outstanding work.

[PATCH] LOG2: Implement a general integer log2 facility in the kernel

2006-12-08T16:28:51+00:00

This facility provides three entry points: ilog2() Log base 2 of unsigned long ilog2_u32() Log base 2 of u32 ilog2_u64() Log base 2 of u64 These facilities can either be used inside functions on dynamic data: int do_something(long q) { ...; y = ilog2(x) ...; } Or can be used to statically initialise global variables with constant values: unsigned n = ilog2(27); When performing static initialisation, the compiler will report "error: initializer element is not constant" if asked to take a log of zero or of something not reducible to a constant. They treat negative numbers as unsigned. When not dealing with a constant, they fall back to using fls() which permits them to use arch-specific log calculation instructions - such as BSR on x86/x86_64 or SCAN on FRV - if available.

[PATCH] slab: remove kmem_cache_t

2006-12-07T16:39:25+00:00

Replace all uses of kmem_cache_t with struct kmem_cache. The patch was generated using the following script: #!/bin/sh # # Replace one string by another in all the kernel sources. # set -e for file in `find * -name "*.c" -o -name "*.h"|xargs grep -l $1`; do quilt add $file sed -e "1,\$s/$1/$2/g" $file >/tmp/$$ mv /tmp/$$ $file quilt refresh done The script was run like this sh replace kmem_cache_t "struct kmem_cache" Signed-off-by: Christoph Lameter Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds
