The x86/Voyager subarch used to have this distinction between 'x86 SMP support' and 'Voyager SMP support': config X86_SMP bool depends on SMP && ((X86_32 && !X86_VOYAGER) || X86_64) This is a pointless distinction - Voyager can (and already does) use smp_ops to implement various SMP quirks it has - and it can be extended more to cover all the specialities of Voyager. So remove this complication in the Kconfig space. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

x86/Voyager has this quirk for SCx200 support: config SCx200 tristate "NatSemi SCx200 support" depends on !X86_VOYAGER Remove it - Voyager users can disable drivers they dont need. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Remove Voyager Kconfig quirk: just like any other hardware platform users of Voyager systems can configure in the hardware drivers they need. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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) Signed-off-by: Ingo Molnar <mingo@elte.hu>

CONFIG_BROKEN has been removed from the upstream kernel years ago, but X86_VOYAGER still had a stale reference to it - remove it. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Remove the 32-bit subarchitecture support code. All subarchitectures but Voyager have been converted. Voyager will be done later or will be removed. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

Nothing exciting - a few subarches dont want APIC remote reads to be performed - the others are content with the default method. - extend the generic code to handle NULL methods - clear out dummy methods and replace them with NULL - clean up: remove wrapper macros, etc. 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. - extend the generic code to handle NULL methods - clear out dummy methods and replace them with NULL - clean up: remove wrapper macros, etc. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. Signed-off-by: Ingo Molnar <mingo@elte.hu>

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. - spread out the quirks into separately named per apic driver methods - prefix the standard PC methods with default_ - get rid of wrapper macro obfuscation - clean up various details Signed-off-by: Ingo Molnar <mingo@elte.hu>
