Jeff, Andrew,

the attached patch is needed to make UML work on 2.6.1-mm5. It does the 
following things:

 - update UML to the extable changes

 - remove __i386__ kgdb dependency from config.h. The config.h kgdb.h 
   thing is a kludge by itself i think - but this change doesnt make it
   any better. It might break amd64 which has CONFIG_X86 too iirc - but 
   this unbreaks UML compilation.

 - move i386 TASK_SIZE definition from page.h back to processor.h. This 
   was moved to page.h by the 4G/4G patch and there's no reason why we 
   couldnt leave it in processor.h. This unbreaks UML compilation.

 - a top Makefile change broke UML compilation. I'm not sure why, but it 
   makes the difference.

with this patch applied, UML compiles & works fine.
