Michal Simek de93c3c119 microblaze: Fix ASM optimized code for LE
Microblaze little-endian doesn't support ASM optimized library
functions(memcpy/memmove). Kconfig doens't contain
any information about endian that's why it is necessary to
check it in the source code.
The code is used with barrel shifter is used.

Michal Simek 3370d82f3b microblaze: Fix __muldi3 function for little-endian.
__muldi3 was written for big endian platforms.
Code contained half word read/write instructions which
are not compatible with little endian cpu.
Asm __muldi3 implementation is replaced by C version.

Michal Simek 1180b28ca8 microblaze: Support C optimized lib functions for little-endian
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.

Michal Simek ca3865bae5 microblaze: Support word copying in copy_tofrom_user
Word copying is used only for aligned addresses.
Here is space for improving to use any better copying technique.
Look at memcpy implementation.

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

Arnd Bergmann 732703af9c microblaze: clean up checksum.c
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.
