be performed - the others are content with the default method.

Nothing actually restores the NMI vector - so remove this
logic altogether.
Signed-off-by: NIngo Molnar <mingo@elte.hu>

Only NUMAQ does something substantial here, because it initializes
via NMIs (not via INIT as standard SMP startup) - so it needs to
store and restore the NMI vector.

64-bit x86 has zero for ->trampoline_phys_low/high, but the smpboot
code can use these values - so it's better to set them up to their
correct values.

Only ES7000 has a real ->enable_apic_mode() method, the other

So mark the vector as NULL, extend the generic code to handle
NULL -setup_portio_remap() entries and remove all the empty
handlers.

only NUMAQ uses this quirk: to prevent the timer IRQ from being added

All other genapic templates can have a NULL ->multi_timer_check()

Also, extend the generic code to treat a NULL pointer accordingly.
