H A Dpvcpu_enum.cdiff 269511 Mon Aug 04 07:12:25 MDT 2014 royger xen: change quality of the MADT ACPI enumerator

Lower the quality of the MADT ACPI enumerator, so on Xen Dom0 we can
force the usage of the Xen mptable enumerator even when ACPI is
detected.

This is needed because Xen might restrict the number of vCPUs
available to Dom0, but the MADT ACPI table parsed in FreeBSD is the
native one (which enumerates all the CPUs available in the system).
