1)I cannot understand why the WEAK entries are required after the
bad_subarch label :/ Any hints?
2)I think that xen doesn't use any more the hardware subarch boot
parameter, and uses a 'different' path/boot sequence, hence the
xen_entry in head_32.S is not needed any more. Am I missing something?

Thanks! :)
