[PATCH v1 0/3] crypto: powerpc/md5

The following patches add support for optimized MD5
calculation on PPC processors. It completes the previous
patches to provide a comprehensive IPsec algorithm support
for low power routers without hardware crypto acceleration. 
The implementation is endian independant. Although only 
tested on 32 bit CPU it should run on 64 bit too.

Performance numbers from insmod tcrypt sec=3 mode=302 taken
on e500v2 800 MHz (TP Link WDR4900)
