Voyager has this Kconfig quirk for suspend/resume:

 config ARCH_SUSPEND_POSSIBLE
 	def_bool y
 	depends on !X86_VOYAGER

The proper mechanism to not suspend on a piece of hardware to disable
CONFIG_SUSPEND. Remove the quirk.

Voyager has this hibernation quirk:

 config ARCH_HIBERNATION_POSSIBLE
 	def_bool y
	depends on !SMP || !X86_VOYAGER

Hibernation is a generic facility provided on all x86 platforms. If it
is buggy on Voyager then that bug should be fixed - not worked around.

x86/Voyager has this KGDB quirk:

	select HAVE_ARCH_KGDB if !X86_VOYAGER

This is completely pointless - there's nothing in KGDB that cannot work
on Voyager. Remove it.

Voyager and other subarchitectures have this Kconfig quirk:

 	select HAVE_KVM if ((X86_32 && !X86_VOYAGER && !X86_VISWS && !X86_NUMAQ) || X86_64)

This is unnecessary, as KVM cleanly detects based on CPUID capabilities.

x86/Voyager has this quirk for SCx200 support:

Remove it - Voyager users can disable drivers they dont need.

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,

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.)

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

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.
