Hello Herbert,
this little patch series moves the the key generation routine and the four
tables which are used encrypt/decrypt function into a separate module.
Currently I converted the generic AES and the x86_64 variant. My 32bit asm
is rusted so the i586 assembly has to wait for a while :)

There are three AES softwore modules in the kernel: One C version
and two arch specific assembly versions. The key expansion routine as
well as the the four lookup tables which are used during encryption
and/or decryption are the same.
This patch simply
