On systems with sufficiently large e820 tables, and several IOAPICs, it is possible for the XENMEM_machine_memory_map callback (and its counterpart, XENMEM_memory_map) to attempt to return an e820 table with more than 128 entries. This callback adds entries to the BIOS-provided e820 table to account for IOAPIC registers, which, on sufficiently large systems, can result in an e820 table that is too large to copy back into xen_e820_map. This change simply increases the size of xen_e820_map to E820_X_MAX to ensure that there is enough room to store the entire e820 map returned from this callback.
