Atsushi Nemoto f860c90bd6 [MIPS] csum_partial and copy in parallel 
Implement optimized asm version of csum_partial_copy_nocheck,
csum_partial_copy_from_user and csum_and_copy_to_user which can do
calculate and copy in parallel, based on memcpy.S.

Atsushi Nemoto 773ff78838 [MIPS] Optimize flow of csum_partial 
Delete dead codes at end of the function and move small_csumcopy
there.  This makes some labels (maybe_end_cruft, small_memcpy,
end_bytes, out) needless and eliminates some branches.

Atsushi Nemoto 52ffe760ea [MIPS] Make csum_partial more readable 
Use standard o32 register name instead of T0, T1, etc, like memcpy.S.

Atsushi Nemoto 0bcdda0f3a [MIPS] Unify csum_partial.S 
The 32-bit version and 64-bit version are almost equal.  Unify them.  This
makes further improvements (for example, copying with parallel, supporting
PREFETCH, etc.) easier.
