2009-01-29x86: replace CONFIG_X86_SMP with CONFIG_SMPIngo Molnar
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>
2009-01-29x86/Voyager: remove ARCH_SUSPEND_POSSIBLE Kconfig quirkIngo Molnar
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>
2009-01-29x86/Voyager: remove HIBERNATION Kconfig quirkIngo Molnar
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>
2009-01-29x86/Voyager: remove KGDB Kconfig quirkIngo Molnar
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>
2009-01-29x86/Voyager: remove KVM Kconfig quirkIngo Molnar
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>
2009-01-29x86/Voyager: remove NATSEMI Kconfig quirkIngo Molnar
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>
2009-01-29x86/Voyager: remove MCA Kconfig quirkIngo Molnar
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>
2009-01-29x86: disable Voyager temporarilyIngo Molnar
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>
2009-01-29x86/Voyager: clean up BROKEN Kconfig referenceIngo Molnar
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>
2009-01-29x86: remove subarchitecture supportIngo Molnar
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>
2009-01-29x86: move mach-default/*.h files to asm/Ingo Molnar
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>
2009-01-29x86: remove subarchitecture support codeIngo Molnar
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>
2009-01-29x86, smp: remove mach_ipi.hIngo Molnar
Move mach_ipi.h definitions into genapic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, bigsmp: consolidate header codeIngo Molnar
Move all the asm/bigsmp/*.h definitions into bigsmp_32.c. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, bigsmp: consolidate codeIngo Molnar
Move all code to arch/x86/kernel/bigsmp_32.c. With this it ceases to rely on any build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, NUMAQ: Consolidate codeIngo Molnar
Move all NUMAQ code into arch/x86/kernel/numaq.c. With this it ceases to rely on any build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, ES7000: Consolidate codeIngo Molnar
Move all ES7000 code into arch/x86/kernel/es7000_32.c. With this it ceases to rely on any build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: remove mach_apic.h, fixSuresh Siddha
Use apic_read() instead of open-coded mmio. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: remove mach_apic.hIngo Molnar
Spread mach_apic.h definitions into genapic.h. (with some knock-on effects on smp.h and apic.h.) Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86, summit: consolidate code, fixIngo Molnar
Build fix for !NUMA Summit. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, summit: consolidate codeIngo Molnar

2009-01-28x86, numaq: consolidate codeIngo Molnar
Move all the NUMAQ subarch definitions into numaq.c. With this it ceases to depend on build-time subarch features. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->wake_cpuIngo Molnar
- remove macro wrappers Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: remove mach_apicdef.hIngo Molnar
Move its definitions into apic.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: remove mach_mpspec.hIngo Molnar
Move its definitions into mpspec.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: eliminate asm/mach-*/mach_mpparse.hIngo Molnar

2009-01-28x86, smp: eliminate asm/mach-default/mach_wakecpu.hIngo Molnar
Spread mach_wakecpu.h's definitions into apic.h and genapic.h and remove mach_wakecpu.h. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, ES7000: consolidate the APIC codeIngo Molnar
Consolidate all the ES7000 APIC code into arch/x86/mach-generic/es7000.c. With this ES7000 ceases to rely on any subarchitecture include files. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->inquire_remote_apic() methodsIngo Molnar
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>
2009-01-28x86, smp: remove ->restore_NMI_vector()Ingo Molnar
Nothing actually restores the NMI vector - so remove this logic altogether. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: refactor ->store/restore_NMI_vector() methodsIngo Molnar
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>
2009-01-28x86, smp: refactor ->smp_callin_clear_local_apic() methodsIngo Molnar
Only NUMAQ does something substantial here, because it initializes via NMIs (not via INIT as standard SMP startup) - so it needs to reset the APIC. - 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>
2009-01-28x86, smp: refactor ->wait_for_init_deassert()Ingo Molnar
- spread out the namespace on a per APIC driver basis - handle a NULL ->wait_for_init_deassert() as a 'dont wait' default method - remove NUMAQ and Summit handlers Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: set ->trampoline_phys_low/high on 64-bit tooIngo Molnar
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>
2009-01-28x86, smp: clean up ->trampoline_phys_low/high handlingIngo Molnar
- spread out the namespace on a per apic driver basis - remove wrapper macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: untangle the send_IPI_*() jungleIngo Molnar
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>
2009-01-28x86, apic: refactor ->cpu_mask_to_apicid*()Ingo Molnar
- spread out the namespace on a per driver basis - clean up the functions - get rid of macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: get rid of *_APIC_ID_MASK definitionsIngo Molnar
Impact: cleanup Remove the *_APIC_ID_MASK subarch definitions and move them straight to the genapic driver initialization code. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->apic_id_mask & APIC_ID_MASKIngo Molnar
- spread out the namespace on a per driver basis - get rid of wrapper macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->get_apic_id() & GET_APIC_ID()Ingo Molnar
- spread out the namespace on a per driver basis - get rid of macro wrappers - small cleanups Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: consolidate the ->mps_oem_check() codeIngo Molnar
- spread out the mps_oem_check() namespace on a per APIC driver basis Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, mpparse: call the generic quirk handlers earlyIngo Molnar
Call all the registered MPS quirk handlers early. These methods scan low RAM typically for specific signatures so are safe to be called early. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, smp: clean up mps_oem_check()Ingo Molnar
Impact: cleanup - allow NULL ->mps_oem_check() entries - clean up the code flow Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: refactor ->phys_pkg_id()Ingo Molnar
Refactor the ->phys_pkg_id() methods: - namespace separation - macro wrapper removal - open-coded calls to the methods in the generic code Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: unify phys_pkg_id()Ingo Molnar
- unify the call signature of 64-bit to that of 32-bit - clean up the types all around - clean up namespace contamination Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, es7000: clean up es7000_enable_apic_mode()Ingo Molnar
- eliminate the needless es7000_enable_apic_mode() complication which was not apparent prior the namespace cleanups - clean up the control flow in es7000_enable_apic_mode() - other cleanups Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->enable_apic_mode() subarch methodsIngo Molnar
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. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->check_phys_apicid_present() subarch methodsIngo Molnar
- spread out the namespace to per driver methods - extend it to 64-bit as well so that we can use apic->check_phys_apicid_present() unconditionally Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86: refactor ->setup_portio_remap() subarch methodsIngo Molnar
Only NUMAQ has a real ->setup_portio_remap() 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. Also move the NUMAQ method from the header file into the apic driver .c file. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-28x86, apic: clean up ->apicid_to_cpu_present()Ingo Molnar
- separate the namespace - remove macros Signed-off-by: Ingo Molnar <mingo@elte.hu>
