2008-11-06xtensa: move headers files to arch/xtensa/includeChris Zankel
Move all header files for xtensa to arch/xtensa/include and platform and variant header files to the appropriate arch/xtensa/platforms/ and arch/xtensa/variants/ directories. Moving the files gets also rid of all uses of symlinks in the Makefile. This has been completed already for the majority of the architectures and xtensa is one out of six missing.

2007-10-22Change table chaining layoutJens Axboe
Change the page member of the scatterlist structure to be an unsigned long, and encode more stuff in the lower bits: - Bits 0 and 1 zero: this is a normal sg entry. Next sg entry is located at sg + 1. - Bit 0 set: this is a chain entry, the next real entry is at ->page_link with the two low bits masked off. - Bit 1 set: this is the final entry in the sg entry. sg_next() will return NULL when passed such an entry. It's thus important that sg table users use the proper accessors to get and set the page member. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2007-05-02PCI: scatterlist.h needs types.hJean Delvare
Most architectures' scatterlist.h use the type dma_addr_t, but omit to include <asm/types.h> which defines it. This could lead to build failures, so let's add the missing includes.
