x86/Voyager does not build right now and it's unclear whether it will
be cleaned up and ported to the subarch-less 32-bit x86 code - so disable
it for now.

If it's fixed we'll re-enable it - or remove it after some time. There's
a very low number of systems running development kernels on x86/Voyager
currently. (one or two on the whole planet)

CONFIG_BROKEN has been removed from the upstream kernel years ago,
but X86_VOYAGER still had a stale reference to it - remove it.

Remove the 32-bit subarchitecture support code.

All subarchitectures but Voyager have been converted. Voyager will be
done later or will be removed.

We are getting rid of subarchitecture support - move the hook files
to asm/. (These are now stale and should be replaced with more explicit
runtime mechanisms - but the transition is simpler this way.)
Signed-off-by: Ingo Molnar <mingo@elte.hu>

Remove remaining bits of the subarchitecture code. Now that all the
special platforms are runtime probed and runtime handled, we can remove
these facilities.

Nothing exciting - a few subarches dont want APIC remote reads to
be performed - the others are content with the default method.

Nothing actually restores the NMI vector - so remove this
logic altogether.
Signed-off-by: Ingo 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.

Our send_IPI_*() methods and definitions are a twisted mess: the same
symbol is defined to different things depending on .config details,
in a non-transparent way.

Call all the registered MPS quirk handlers early. These methods scan
low RAM typically for specific signatures so are safe to be called
early.

Only ES7000 has a real ->enable_apic_mode() method, the other
subarchitectures define it but keep it empty.

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