so NUMAQ can use that to call numaq_pre_time_init()
This allows us to remove a NUMAQ special from arch/x86/kernel/setup.c.
(and paves the way to remove the NUMAQ subarch)

add these new x86_quirks methods:
int *mpc_record;
int (*mpc_apic_id)(struct mpc_config_processor *m);
void (*mpc_oem_bus_info)(struct mpc_config_bus *m, char *name);
void (*mpc_oem_pci_bus)(struct mpc_config_bus *m);
void (*smp_read_mpc_oem)(struct mp_config_oemtable *oemtable,
unsigned short oemsize);
... and move NUMAQ related mps table handling to numaq_32.c.
also move the call to smp_read_mpc_oem() to smp_read_mpc() directly.
Should not change functionality, albeit it would be nice to get it
tested on real NUMAQ as well ...

fix:

got this on a test-system:
calling numaq_tsc_disable+0x0/0x39
NUMAQ: disabling TSC
initcall numaq_tsc_disable+0x0/0x39 returned 0 after 0 msecs
that's because we should not be using arch_initcall to call numaq_tsc_disable.
need to call it in setup_arch before time_init()/tsc_init()
and call it in init_intel() to make the cpu feature bits right.

... 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.

this way 32-bit is more similar to 64-bit, and smarter e820 and numa.

so we could fall back to one node numa.
