The following patch repairs kicking of non-present cpus by making
cpu_present_to_apicid() bounds-check its argument.  It also corrects the
same issue on NUMA-Q by correctly passing the generated artificial APIC ID
instead of the raw value discovered in the MP table.

A miscellaneous compilefix for CONFIG_ACPI_BOOT is also included for
completeness.
