[PATCH] Fix 8xx compile errors

[John Tyner <jtyner@cs.ucr.edu>]

[-- Attachment #1: Type: text/plain, Size: 518 bytes --]

Building for 8xx fails to compile due to errors in a couple of places. 
The first is due to the casting of an lvalue (if I remember correctly), 
and the second was due to the cpmp variable being declared static even 
though the headers previously defined it as extern. The following patch 
corrects these errors. The patch is against 2.4 since that's what I'm 
working with. (I've been unable to get 2.6 to run properly on my 
hardware so far.)

Please CC me on any responses since I'm not subscribed.

Thanks,
John
