This is a rather monstrous patch, but the CRIS port hadn't been updated in quite 
a while, and a lot of the stuff that had changed since the last update was 
interconnected.  In addition to this, I got rid of support for a now obsolete 
ABI (instead of updating it) which further increases the size of the patch.

Andrew, it was a while since I contributed to the tree, and my public key has 
most likely changed since then.  Should I send you a new identity.pub?

I realize this patch comes very close to branching for 6.1, so if it fits badly 
with the 6.1 schedule for whatever reason then I'm prepared to wait until later.
