Thanks, that was very helpful.

The biggest problem was due to the removal of three
includes from include/xen/slab.h... this was obscured
by some of the other changes.

Could you put these back in where they were before please?
(If necessary, with a ifdef ia64 for now and we can sort
it out later.)

< #include <xen/mm.h>
< #include <xen/cache.h>
< #include <xen/types.h> 

Actually, it appears I only need xen/mm.h if that helps.
