alpha: Detect Super IO chip, no IDE on Avanti, enable EPP19

2010-06-15T18:19:08Z

This patch probes for the Super IO chip and reserves the IO range when found. It avoids enabling the IDE interface on the Avanti family, since none has IDE. It enables the Enhanced Parallel Port v1.9 feature. Signed-off-by: Morten H. Larsen Signed-off-by: Matt Turner

alpha: fix pci_mmap_resource API breakage

2010-06-15T18:19:07Z

Caused by 2c3c8bea608866d8bd9dcf92657d57fdcac011c5 which was clearly not even compile tested. Signed-off-by: Matt Turner

alpha: fix __arch_hweight32 typo

2010-06-15T18:19:07Z

Typo in 1527bc8b928dd1399c3d3467dd47d9ede210978a renamed hweight32 to __arch_weight32. Signed-off-by: Matt Turner

asm-generic: remove ARCH_HAS_SG_CHAIN in scatterlist.h

2010-05-27T16:12:54Z

There are more architectures that don't support ARCH_HAS_SG_CHAIN than those that support it. This removes removes ARCH_HAS_SG_CHAIN in asm-generic/scatterlist.h and lets arhictectures to define it. It's clearer than defining ARCH_HAS_SG_CHAIN asm-generic/scatterlist.h and undefing it in arhictectures that don't support it.

Revert "endian: #define __BYTE_ORDER"

2010-05-26T15:30:15Z

This reverts commit b3b77c8caef1750ebeea1054e39e358550ea9f55, which was also totally broken (see commit 0d2daf5cc858 that reverted the crc32 version of it). As reported by Stephen Rothwell, it causes problems on big-endian machines: > In file included from fs/jfs/jfs_types.h:33, > from fs/jfs/jfs_incore.h:26, > from fs/jfs/file.c:22: > fs/jfs/endian24.h:36:101: warning: "__LITTLE_ENDIAN" is not defined The kernel has never had that crazy "__BYTE_ORDER == __LITTLE_ENDIAN" model. It's not how we do things, and it isn't how we _should_ do things. So don't go there. Requested-by: Stephen Rothwell Signed-off-by: Linus Torvalds

alpha: simplify and optimize sched_find_first_bit

2010-05-25T22:40:28Z

Search only the first 100 bits instead of 140, saving a couple instructions. The resulting code is about 1/3 faster (40K ticks/1000 iterations down to 30K ticks/1000 iterations).

alpha: invoke oom-killer from page fault

2010-05-25T22:40:28Z

As explained in commit 1c0fe6e3bd, we want to call the architecture independent oom killer when getting an unexplained OOM from handle_mm_fault, rather than simply killing current.

Convert alpha to use clocksources instead of arch_gettimeoffset

2010-05-25T22:40:27Z

Alpha has a tsc like rpcc counter that it uses to manage time. This can be converted to an actual clocksource instead of utilizing the arch_gettimeoffset method that is really only there for legacy systems with no continuous counter. Further cleanups could be made if alpha converted to the clockevent model.

endian: #define __BYTE_ORDER

2010-05-25T15:07:02Z

Linux does not define __BYTE_ORDER in its endian header files which makes some header files bend backwards to get at the current endian. Lets #define __BYTE_ORDER in big_endian.h/litte_endian.h to make it easier for header files that are used in user space too. In userspace the convention is that 1. _both_ __LITTLE_ENDIAN and __BIG_ENDIAN are defined, 2. you have to test for e.g. __BYTE_ORDER == __BIG_ENDIAN.
