Arjan, I've been doing some work on traps_32.c porting over the oops_begin()/oops_end()/_die() arrangement from traps_64.c and then use it in unifying some more parts of fault.c. If you have other work in this area, I'll hold off until your stuff goes in...feel free to send me any work in progress stuff and I can try to coordinate with you.
