2007-10-23blackfin: remove sg_address()Jens Axboe
I would have replaced it with sg_virt(), but it doesn't appear to be used at all. Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

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>
2007-10-22Change 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>

2007-10-17Remove dma_cache_(wback|inv|wback_inv) functionsRalf Baechle
dma_cache_(wback|inv|wback_inv) were the earliest attempt on a generalized cache managment API for I/O purposes. Originally it was basically the raw MIPS low level cache API exported to the entire world. The API has suffered from a lack of documentation, was not very widely used unlike it's more modern brothers and can easily be replaced by dma_cache_sync. So remove it rsp. turn the surviving bits back into an arch private API, as discussed on linux-arch.

2007-10-17remove strict ansi check from __u64 in asm/types.hOlaf Hering
Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on 32bit targets. GCC can be made to warn about usage of long long types with ISO C90 (-ansi), but only with -pedantic. You can write this in a way that even then it doesn't cause warnings, namely by: #ifdef __GNUC__ __extension__ typedef __signed__ long long __s64; __extension__ typedef unsigned long long __u64; #endif The __extension__ keyword in front of this switches off any pedantic warnings for this expression.

DECLARE_MUTEX_LOCKED was used for semaphores used as completions and we've got rid of them. Well, except for one in libusual that the maintainer explicitly wants to keep as semaphore.
