Merge branch 'for-4.3/sg' of git://git.kernel.dk/linux-block
Pull SG updates from Jens Axboe: "This contains a set of scatter-gather related changes/fixes for 4.3: - 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" * 'for-4.3/sg' of git://git.kernel.dk/linux-block: lib: scatterlist: add sg splitting function scatterlist: use sg_phys() crypto/omap-sham: remove an open coded access to ->page_link scatterlist: remove open coded sg_unmark_end instances crypto: replace scatterwalk_sg_chain with sg_chain target/rd: always chain S/G list scatterlist: allow limited chaining without ARCH_HAS_SG_CHAIN
