[PATCH] FRV: Miscellaneous fixes
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.
