slub: zero page to fix boot crashes

Latest mmotm rarely boots if SLUB is enabled: earlyprintk=vga shows
it crashing with various backtraces.  The memset has now been removed
from kmem_cache_open(), so kmem_cache_init() needs to zero its page.
This gets SLUB booting reliably again.

arm/crypto: Add optimized AES and SHA1 routines Add assembler versions of AES and SHA1 for ARM platforms. This has provided up to a 50% improvement in IPsec/TCP throughout for tunnels using AES128/SHA1.
