Optimized C library functions can rapidly speedup the kernel.
memset doesn't need to be optimized because there is no difference
in behavior on little/big endian cpu.

Word copying is used only for aligned addresses.
Here is space for improving to use any better copying technique.
Look at memcpy implementation.

This is first patch which clear part of uaccess.h.
uaccess.h will be clear later.

The microblaze checksum code is mostly identical to
the asm-generic+lib version, so use that instead.

This changes the function prototypes in the checksum code
to have the usual prototypes, typically by turning int
arguments into __wsum.
Also change csum_partial_copy_from_user() to operate
on the right address space and export ip_fast_csum,
which is used in modular networking code.
The new version is now sparse-clean including endianess
checks.

This function is neither declared nor used anywhere
outside of ppc32, so remove it from microblaze.
