Tested by OscarL and confirmed to be working on at least one machine, though on others it hangs, so leaving out of the default builds for now. This adds an "acpi_processor_id" field to x86 arch_cpu_info, gleaned from the MADT, so we can match our cpu_ents to ACPI processor objects. (FreeBSD does a similar mapping, see their acpi_cpu_probe method.)
