------------------------------------------------------
Subject: uml: print coredump limits
From: Jeff Dike <jdike@xxxxxxxxxxx>
Print out core dump limits at boot time. This is to allow core dumps
to be collected if something goes very wrong and to tell if a core
dump isn't going to happen because of a resource limit.
