Note that the BCM4710 does not support the wait instruction, this
is not a mistake in the code.
It originally comes from the OpenWrt patches.

This patch renames it for 3 reasons:
- "CONFIG" pattern is used by Kconfig. Now this macro is
no more defined by Kconfig but by Kbuild itself make this
clear by translating "CONFIG" into "KBUILD".
- "ELF32" word is improper because it is irrelevant to ELF
format and it makes confusion with CONFIG_BOOT_ELF32. So
translate it with SYM32.
- Add "64BIT" part to make clear that this macro implies a
64 bits kernel.

We do not rely on user anymore to setup this config correctly.
Instead we make our choice depending on the load address.
If we want to force Kbuild to use ELF64 format whatever
the load address we can still do:
$ make BUILD_ELF32=no

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
