forbid asm/bitops.h direct inclusion

forbid asm/bitops.h direct inclusion

Because of compile errors that may occur after bit changes if asm/bitops.h is
included directly without e.g.  linux/kernel.h which includes linux/bitops.h,
forbid direct inclusion of asm/bitops.h.  Thanks to Adrian Bunk.

mips: fix bitops

2007-10-18T21:37:29+00:00

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.

bitops: introduce lock ops

2007-10-18T21:37:29+00:00

Introduce test_and_set_bit_lock / clear_bit_unlock bitops with lock semantics.
Convert all architectures to use the generic implementation.
