Description Jayson King 2008-11-15 20:05:26 EST
Description of problem:
There is an x86_64 optimized assembly module for twofish, "twofish-x86_64". But when I access a twofish dm-crypt device, the module "twofish" is loaded instead of "twofish-x86_64", even though my CPU is x86_64.

In comparison, if an AES dm-crypt device is used, the module "aes-x86_64" is loaded.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. use a twofish encrypted dm-crypt device
2. lsmod

Actual results:
twofish is loaded rather than twofish-x86_64

Expected results:
twofish-x86_64 should be loaded

looks like the best way to fix this is just to not build the non-x86_64 versions on 64bit kernels.  I'll make the change.
Comment 2 Jayson King 2008-11-19 01:29:17 EST
Yes, that fixes it.
