Changes with respect to v1 as per comments received
o. Rebased to linux-next as of 20091216
o. The selection is based exclusive of fsldma
o. Intoduced a new Kernel Configuration variable
  *. This enables selecting the Cryptographic functionality
     of Talitos along with fsldma.
  *. Disables the XOR parity calculation offload, if fsldma enabled
     either as kernel in-built or as a module
  *. Once the inter-operability with fsldma is resolved, this option
     can be removed
wait, why can't the interoperability bug be fixed in the first place?
I agree w/Kim.  We need to better understand what the bug is and how to reproduce it so we can get to the root cause.

Paper taping over it by disabling fsldma is not the right solution.
Hopefully this prompts fsldma authors to get involved because the 
interoperability issue has been out there without comment*, just 
band-aids, since October.

* well one comment from Ira saying the interrupt functionality worked 
for him.
