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.

asm-generic: add NEED_SG_DMA_LENGTH to define sg_dma_len()2010-05-27T16:12:54+00:00FUJITA Tomonorifujita.tomonori@lab.ntt.co.jp2010-05-26T21:44:32+00:00urn:sha1:18e98307de0d746cb0845ebf66535ce2184c25a2
There are only two ways to define sg_dma_len(); use sg->dma_length or
sg->length. This patch introduces NEED_SG_DMA_LENGTH that enables
architectures to choose sg->dma_length or sg->length.

asm-generic: remove ISA_DMA_THRESHOLD in scatterlist.h2010-05-27T16:12:54+00:00FUJITA Tomonorifujita.tomonori@lab.ntt.co.jp2010-05-26T21:44:30+00:00urn:sha1:204f3a04449a9a775e465f7d87bcab08f170e59e
This is the first half of the attempt to use asm-generic/scatterlist.h
on every architecture.
There are only two ways to define scatterlist structure. So it's easy
to convert every architecture to use asm-generic/scatterlist.h.
This patch:
The trick for ISA_DMA_THRESHOLD in asm-generic/scatterlist.h doesn't work
for powerpc. This lets architectures defin ISA_DMA_THRESHOLD.
Hopefully, we can remove ISA_DMA_THRESHOLD in the future; we can do better
to decide if the bouncing is necessary or not.

asm-generic: add generic versions of common headers2009-06-11T19:02:37+00:00Arnd Bergmannarnd@arndb.de2009-05-13T22:56:33+00:00urn:sha1:aafe4dbed0bf6cbdb2e9f03e1d42f8a540d8541d
These are all kernel internal interfaces that get copied
around a lot. In most cases, architectures can provide
their own optimized versions, but these generic versions
can work as well.
I have tried to use the most common contents of each
header to allow existing architectures to migrate easily.
Thanks to Remis for suggesting a number of cleanups.
