Kernel commit 721255b982 ("genirq: Use a maple tree for interrupt
descriptor management"), which is contained in Linux 6.5-rc1 and later
kernels, replaced irq_desc_tree with a maple tree sparse_irqs.
Without the patch, "irq [-a|-s]" options fail with an error, e.g. the
following on x86_64, on kernels configured with CONFIG_SPARSE_IRQ=y.

irq: x86_64_dump_irq: irq_desc[] or irq_desc_tree do not exist?

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.
