2.6.18 compile problem: undefined reference to crypto_tfm_ctx_offset

I get this error:

# LANG=C make ARCH=um vmlinux

I guess, i just have to disable some crypto-stuff, but i wanted to inform you about that.

I fixed this a few days ago, and the fix is in 2.6.18-bb1 (tell me if I forgot to upload it). It is the one attached but I do not remember if it applies by itself or has dependencies, so try -bb1.

Inform me of my mistakes, so I can keep imitating Homer Simpson's "Doh!".
