[GIT PULL] SG changes for 4.3

[Jens Axboe]

Hi Linus,

This pull request contains a set of scatter-gather related changes/fixes
for 4.3. It contains:

- Add support for limited chaining of sg tables even for architectures
  that do not set ARCH_HAS_SG_CHAIN. From Christoph.

- Add sg chain support to target_rd. From Christoph.

- Fixup open coded sg->page_link in crypto/omap-sham. From Christoph.

- Fixup open coded crypto ->page_link manipulation. From Dan.

- Also from Dan, automated fixup of manual sg_unmark_end()
  manipulations.

- Also from Dan, automated fixup of open coded sg_phys()
  implementations.

- From Robert Jarzmik, addition of an sg table splitting helper that
  drivers can use.

Please pull!
