[MIPS] Update asm string header
This patches contains several bugfixes and cleanups in the latest upstream: - Don't include linux/config.h - Remove buggy inline version of memscan. - Merge with Linux 2.6.11-rc3. - Fix undefined reference to strcpy in binfmt_misc caused by gcc 3.4. - Goodbye mips64. 31704 lines of code bite the dust. - Replace extern inline with static inline. - Fix return value of strncpy. - Remove a bunch more "$1" clobbers.
