I assume switch_to_proc_kcore() isn't Xen specific but since it will
happen on all our dom0's would you care if I continued with it?
Right.
And as far as fixing this, if devmem_is_restricted() is patched to return
FALSE if it's recursively called, that seems to work for me. Or were
you thinking of hacking PRINT_ERROR_MESSAGE() up even further?
