Since makedumpfile commit 349a0ed1, it is now possible to save Xen dumps in compressed kdump format. This patch set adds support for these files. Two new files, xen_dom0.c and xen_dom0.h, have been added to provide the common functionality required by both ELF and compressed kdump formats. (ptesarik@suse.cz)
