2009-01-29x86/Voyager: remove X86_HT Kconfig quirkIngo Molnar
Voyager has this Kconfig quirk: depends on (X86_32 && !X86_VOYAGER) || X86_64 That is unnecessary as HT support is CPUID driven and explicitly enumerated. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: generalize boot_cpu_idIngo Molnar
x86/Voyager can boot on non-zero processors. While that can probably be fixed by properly remapping the physical CPU IDs, keep boot_cpu_id for now for easier transition - and expand it to all of x86. Signed-off-by: Ingo Molnar <mingo@elte.hu>
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, 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>

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>

Build fix for !NUMA Summit. Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-01-29x86: tone down mtrr_trim_uncached_memory() warningIngo Molnar
kerneloops.org is reporting a lot of these warnings that come due to vmware not setting up any MTRRs for emulated CPUs: | Reported 709 times (14696 total reports) | BIOS bug (often in VMWare) where the MTRR's are set up incorrectly | or not at all | | This warning was last seen in version 2.6.29-rc2-git1, and first | seen in 2.6.24. | | More info: | http://www.kerneloops.org/searchweek.php?search=mtrr_trim_uncached_memory Keep a one-liner KERN_INFO about it - so that we have so notice if empty MTRRs are caused by native hardware/BIOS weirdness.

2009-01-29sh: Fix up T-bit error handling in SH-4A mutex fastpath.Takashi Yoshii
This corrects a deadlock encountered on ap325 in the cases where the mutex is contended and the slow-path needs to be fallen back upon. Signed-off-by: Takashi YOSHII <yoshii.takashi@renesas.com> Signed-off-by: Kuninori Morimoto <morimoto.kuninori@renesas.com> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-01-29sh: Fix up spurious syscall restarting.Paul Mundt
The T-bit manipulation for syscall error checking had the side effect of spuriously returning ERESTART* errno values over EINTR. So, we simplify the error checking a bit and leave the T-bit alone. Reported-by: Kaz Kojima <kkojima@rr.iij4u.or.jp> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
2009-01-29sh: fcnvds fix with denormalized numbers on SH-4 FPU.Carmelo AMOROSO
This fixes a bug in the FPU exception handler for the FCNVDS instruction. To get the register number the instruction is shifted right by 9, though it should be shifted right by 8.

2009-01-29sh: Handle calling csum_partial with misaligned dataStuart Menefy
In rare circumstances csum_partial() can be called with data which is not 16 or 32 bit aligned. This is been observed with RPC calls for NFS file systems for example. Add support for handling this without resorting to the misaligned fixup code (which is why this hasn't been seen as a problem). This mimics the i386 version, which has had this support for some time.

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>
