[RFC PATCH 0/2] AES in CBC/CTR/XTS modes using ARMv8 Crypto Extensions

[Ard Biesheuvel]

Hello all,

This is a first attempt at getting something implemented that uses the ARMv8
crypto extensions for performing AES encryption in CBC, CTR and XTS modes.

The first patch moves the ablk helper code out of arch/x86. This code is used
to automagically instantiate async blkciphers based on the synchronous ones in
my implementation.

The second patch contains the actual AES code. Note that this is only compile
tested, there are most likely numerous bugs that need to be shaken out before
this will even run, so consider yourselves warned.

Comments highly appreciated,

Regards,
Ard.
