They contain 64-bit instructions so wouldn't work on 32-bit kernels or
32-bit hardware. Since there are no users, blow them away. They
probably were only ever created because there are atomic_sub_if_positive
and atomic_dec_if_positive which exist only for sake of semaphores.

A "cleanup" almost two years ago deleted the old definition from
<asm/fcntl.h>, so asm-generic/fcntl.h defaulted it to the the same
value as FASYNC ... which happened to be the wrong thing.

The __pa() for those did assume that all symbols have XKPHYS values and
the math fails for any other address range.

Following a strict interpretation the empty definition of irq_enable_hazard
has always been a bug - but an intentional one because it didn't bite.
This has now changed, for uniprocessor kernels mm/slab.c:do_drain()
[...]
on_each_cpu(do_drain, cachep, 1, 1);
check_irq_on();
[...]
may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting
in a back-to-back hazard.

For the generation of asm-offset.h to work these need to be evaulatable
by gcc as a constant expression. This issue did exist for a while but
didn't bite because they're only in asm-offset.h for debugging purposes.

EDAC has a foundation to perform software memory scrubbing, but it requires a
per architecture (atomic_scrub) function for performing an atomic update
operation. Under X86, this is done with a
lock: add [addr],0
in the file asm-x86/edac.h
This patch provides the MIPS arch with that atomic function, atomic_scrub() in
asm-mips/edac.h
