kbuild: Replace remaining "depends" with "depends on"

2007-02-17T18:05:24+00:00

Replace the very few remaining "depends" Kconfig directives with "depends on". Signed-off-by: Robert P. J. Day Signed-off-by: Adrian Bunk

[PATCH] mark struct file_operations const 2

2007-02-12T17:48:44+00:00

Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

[PATCH] Dynamic kernel command-line: v850

2007-02-12T17:48:39+00:00

1. Rename saved_command_line into boot_command_line. 2. Set command_line as __initdata. Signed-off-by: Alon Bar-Lev Cc: Miles Bader 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] V850: user ARRAY_SIZE macro when appropriate

2007-02-11T18:51:24+00:00

Use ARRAY_SIZE macro already defined in linux/kernel.h Signed-off-by: Ahmed S. Darwish Cc: Miles Bader Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

[PATCH] optional ZONE_DMA: introduce CONFIG_ZONE_DMA

2007-02-11T18:51:18+00:00

This patch simply defines CONFIG_ZONE_DMA for all arches. We later do special things with CONFIG_ZONE_DMA after the VM and an arch are prepared to work without ZONE_DMA. CONFIG_ZONE_DMA can be defined in two ways depending on how an architecture handles ISA DMA. First if CONFIG_GENERIC_ISA_DMA is set by the arch then we know that the arch needs ZONE_DMA because ISA DMA devices are supported. We can catch this in mm/Kconfig and do not need to modify arch code. Second, arches may use ZONE_DMA in an unknown way. We set CONFIG_ZONE_DMA for all arches that do not set CONFIG_GENERIC_ISA_DMA in order to insure backwards compatibility. The arches may later undefine ZONE_DMA if their arch code has been verified to not depend on ZONE_DMA.

kconfig: Standardize "depends" -> "depends on" in Kconfig files

2006-12-12T19:04:19+00:00

Standardize the miniscule percentage of occurrences of "depends" in Kconfig files to "depends on", and update kconfig-language.txt to reflect that. Signed-off-by: Robert P. J. Day Signed-off-by: Adrian Bunk

[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] relocatable kernel: Kallsyms generate relocatable symbols

2006-12-07T01:14:04+00:00

Print the addresses of non-absolute symbols relative to _text so that ld will generate relocations. Allowing a relocatable kernel to relocate them. We can't actually use the symbol names because kallsyms includes static symbols that are not exported from their object files. Add the _text symbol definitions to the architectures which don't define it otherwise linker will fail. Signed-off-by: Eric W. Biederman Signed-off-by: Vivek Goyal Signed-off-by: Andi Kleen
