d49c428840 x86: make generic arch support NUMAQ
... so it could fall back to normal numa and we'd reduce the impact of the
NUMAQ subarch.

NUMAQ depends on GENERICARCH
also decouple genericarch numa from acpi.
also make it fall back to bigsmp if apicid > 8.

e0da336468 x86: introduce max_physical_apicid for bigsmp switching
a multi-socket test-system with 3 or 4 ioapics, when 4 dualcore cpus or
2 quadcore cpus installed, needs to switch to bigsmp or physflat.

CPU apic id is [4,11] instead of [0,7], and we need to check max apic
id instead of cpu numbers.

also add check for 32 bit when acpi is not compiled in or acpi=off.
