2007-10-18mips: lock bitopsNick Piggin
mips can avoid one mb when acquiring a lock with test_and_set_bit_lock. Signed-off-by: Nick Piggin <npiggin@suse.de> Cc: Ralf Baechle <ralf@linux-mips.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-10-18mips: fix bitopsNick Piggin
Documentation/atomic_ops.txt defines these primitives must contain a memory barrier both before and after their memory operation. This is consistent with the atomic ops implementation on mips.

2007-10-18[MIPS] time: Delete dead cycles_per_jiffy, mips_timer_ack and null_timer_ackRalf Baechle
cycles_per_jiffy was only ever getting assigned and the function pointer not being called anymore and mips_timer_ack had gotten similarly stale. I leave the remaining assignments unfixed as a lighthouse pointing platform maintainers to what needs a rewrite. These changes make null_timer_ack() unreferenced, so delete that too.

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.

2007-10-17kill DECLARE_MUTEX_LOCKEDChristoph Hellwig
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. So convert that useage to an explicit sema_init and kill of DECLARE_MUTEX_LOCKED so that new code is reminded to use a completion.

This replaces the MIPS-specific to_tm function with the generic rtc_time_to_tm function. The big difference between the two functions is that rtc_time_to_tm uses epoch 70 while to_tm uses 1970, so the result of rtc_time_to_tm needs to be fixed up. Signed-off-by: Ralf Baechle <ralf@linux-mips.org>

It was getting a little big, ugly and a primary source for merge conflicts.
