Fix the FRV cmpxchg_local by breaking the following header dependency loop :
linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h
-> asm-frv/system.h ->
asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h
and
linux/kernel.h -> linux/bitops.h -> asm-frv/bitops.h -> asm-frv/atomic.h ->
asm-generic/cmpxchg_local.h -> typecheck() defined in linux/kernel.h
In order to fix this :
- Move the atomic_test_and_ *_mask inlines from asm-frv/atomic.h (why are they
there at all anyway ? They are not touching atomic_t variables!) to
asm-frv/bitops.h.
Also fix a build issue with cmpxchg : it does not cast to (unsigned long *)
like other architectures, to deal with it in the cmpxchg_local macro.
FRV builds fine with this patch.
Thanks to Adrian Bunk <bunk@kernel.org> for spotting this bug.

My first guess for "fujitsu" was it might be related to the
fujitsu-laptop.c driver...
Move the frv directory one level up since frv is the name of the
architecture in the Linux kernel.

dependency
atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
I agree (with Andi Kleen) this typeof is not needed and more error
prone. All the original atomic.h code that uses cmpxchg (which includes
the atomic_add_unless) uses defines instead of inline functions,
probably to circumvent a circular dependency between system.h and
atomic.h on powerpc (which my patch addresses). Therefore, it makes
sense to use inline functions that will provide type checking.
atomic_add_unless as inline. Remove system.h atomic.h circular dependency.
Digging into the FRV architecture shows me that it is also affected by
such a circular dependency. Here is the diff applying this against the
rest of my atomic.h patches.
It applies over the atomic.h standardization patches.

Make various alterations and fixes to the FRV arch:
(1) Resyncs the FRV system call collection with the i386 arch.
(2) Discards __iounmap() as it's not used.
(3) Fixes the use of the SWAP/SWAPI instruction to get the arguments the right
way around in atomic.h, and also to get the asm constraints correct.
(4) Moves copy_to/from_user_page() to asm/cacheflush.h to be consistent with
other archs.

Several counters already have the need to use 64 atomic variables on 64 bit
platforms (see mm_counter_t in sched.h). We have to do ugly ifdefs to fall
back to 32 bit atomic on 32 bit platforms.
The VM statistics patch that I am working on will also make more extensive
use of atomic64.
This patch introduces a new type atomic_long_t by providing definitions in
asm-generic/atomic.h that works similar to the c "long" type. Its 32 bits
on 32 bit platforms and 64 bits on 64 bit platforms.
Also cleans up the determination of the mm_counter_t in sched.h.

Introduce an atomic_inc_not_zero operation. Make this a special case of
atomic_add_unless because lockless pagecache actually wants
atomic_inc_not_negativeone due to its offset refcount.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
