I think Alex is talking about some lazy way in daily development, due to 
fact that xen is updated more frequently than xenlinux for ia64. In that 
case, sometimes people may only recompile xen after pull latest 
changesets, and then run it with a xenlinux image compiled previously. 
Normally changes of structure and interface will need a complete "make 
world".

However normally people are not aware which changes require a 
complete "make world". Some mismatch may be exposed easily like 
something previously runnable immediately fails now. However there're 
also some potential mismatches may generate weird behavior after long 
run, like some offset changes. So it's always safe though conservative to 
"make world" if time is allowed for developers.

Maybe later we need a MODVERSION-like check between xen and 
xenlinux... :-)

Thanks,
Kevin
