Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.

PCI: scatterlist.h needs types.h 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.

Add CONFIG_DEBUG_SG sg validation Add a Kconfig entry which will toggle some sanity checks on the sg entry and tables. Signed-off-by: Jens Axboe <jens.axboe@oracle.com> 2007-10-22 12:01:06 -06:00			`#ifdef CONFIG_DEBUG_SG`

Change table chaining layout 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.
