2009-08-31x86: Move get/find_smp_config to x86_init_opsThomas Gleixner1-31/+2
Replace the quirk machinery by a x86_init_ops function which defaults to the standard implementation. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-27x86: Move oem_bus_info to x86_init_opsThomas Gleixner1-6/+8

2009-08-27x86: Move smp_read_mpc_oem to x86_init_ops.Thomas Gleixner1-4/+4
Move smp_read_mpc_oem from quirks to x86_init. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-27x86: Move mpc_apic_id to x86_init_opsThomas Gleixner1-4/+6
The mpc_apic_id setup is handled by a x86_quirk. Make it a x86_init_ops function with a default implementation. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-27x86: Sanitize smp_record and move it to x86_init_opsThomas Gleixner1-4/+2
The x86 quirkification introduced an extra ugly hackery with a variable pointer in the mpparse code. If the pointer is initialized then it is dereferenced and the variable set to 0 or incremented. Create a x86_init_ops function and let the affected numaq code hold the function. Default init is a setup noop. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2009-08-26x86, ioapic: Define IO_APIC_DEFAULT_PHYS_BASE constantCyrill Gorcunov1-5/+5
We already have APIC_DEFAULT_PHYS_BASE so just to be consistent. Signed-off-by: Cyrill Gorcunov <gorcunov@openvz.org> LKML-Reference: <20090824175550.927946757@openvz.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-05-18x86, irq: don't call mp_config_acpi_gsi() if update_mptable is not enabledYinghai Lu1-1/+1
Len expressed concern that the update_mptable feature has side-effects on the ACPI code. Make it sure explicitly that the code only ever gets called if the (default disabled) update_mptable boot quirk option is disabled. [ Impact: isolate the update_mptable feature from ACPI code more ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Len Brown <lenb@kernel.org> LKML-Reference: <4A0DC832.5090200@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-05-18x86, irq: update_mptable needs pci_routeirqYinghai Lu1-0/+7
To get all device irq routing and to save them. This is basically an implicit pci=routeirq enablement if (and on if) the update_mptable boot option (which is off by default) has been specified. [ Impact: extend the update_mptable boot opion's scope ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> LKML-Reference: <4A0DB7B4.4060702@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-05-11x86: fix alloc_mptable()Yinghai Lu1-16/+9
Fix the conditions when we stop updating the mptable due to running out of slots. [ Impact: fix memory corruption / non-working update_mptable boot parameter ] Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Jesse Barnes <jbarnes@virtuousgeek.org> Cc: Len Brown <lenb@kernel.org> LKML-Reference: <4A01C3BB.1000609@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-04-12x86: Fix section mismatches in mpparseRakib Mullick1-3/+4
Impact: fix section mismatch In arch/x86/kernel/mpparse.c, smp_reserve_bootmem() has been called and also refers to a function which is in .init section. Thus causes the first warning. And check_irq_src() also requires an __init, because it refers to an .init section.

2009-03-21x86: mpparse.c introduce check_physptr helper functionJaswinder Singh Rajput1-44/+50
To reduce the size of the oversized function __get_smp_config() There should be no impact to functionality. Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com>
2009-03-21x86: mpparse.c introduce smp_dump_mptable helper functionJaswinder Singh Rajput1-8/+10
smp_read_mpc() and replace_intsrc_all() can use same smp_dump_mptable() Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com>

2009-03-18x86: mpparse: clean up code by introducing a few helper functionsJaswinder Singh Rajput1-141/+120
Impact: cleanup Refactor the MP-table parsing code via the introduction of the following helper functions: skip_entry() smp_reserve_bootmem() check_irq_src() check_slot() To simplify the code flow and to reduce the size of the following oversized functions: smp_read_mpc(), smp_scan_config(). There should be no impact to functionality. Signed-off-by: Jaswinder Singh Rajput <jaswinderrajput@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-13x86: clean up output resulting from update_mptable optionJan Beulich1-3/+3
Impact: cleanup Without apic=verbose, using the update_mptable option would result in garbled and confusing output due to the inconsistent use of printk() vs apic_printk(). Signed-off-by: Jan Beulich <jbeulich@novell.com> LKML-Reference: <49B914B6.76E4.0078.0@novell.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-04x86: reserve exact size of mptableYinghai Lu1-2/+2
Impact: save a bit of RAM Get the exact size for the reserve_bootmem() call. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> LKML-Reference: <49AE4922.605@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2009-03-04x86: ioremap mptableYinghai Lu1-1/+20
Impact: fix boot with mptable above max_low_mapped Try to use early_ioremap() to map MPC to make sure it works even it is at the end of ram. Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: Andrew Morton <akpm@linux-foundation.org> LKML-Reference: <49AE4901.3090801@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu> Reported-and-tested-by: Kevin O'Connor <kevin@koconnor.net>
2009-02-23x86: check mptable physptr with max_low_pfn on 32bitYinghai Lu1-3/+12
Impact: fix early crash on LinuxBIOS systems Kevin O'Connor reported that Coreboot aka LinuxBIOS tries to put mptable somewhere very high, well above max_low_pfn (below which BIOSes generally put the mptable), causing a panic. The BIOS will probably be changed to be compatible with older Linus versions, but nevertheless the MP-spec does not forbid an MP-table in arbitrary system RAM, so make sure it all works even if the table is in an unexpected place. Check physptr with max_low_pfn * PAGE_SIZE.

2009-01-29x86: rename X86_GENERICARCH to X86_32_NON_STANDARDIngo Molnar1-1/+1
X86_GENERICARCH is a misnomer - it contains non-PC 32-bit architectures that are not included in the default build. Rename it to X86_32_NON_STANDARD. Signed-off-by: Ingo Molnar <mingo@elte.hu>

2009-01-28x86, mpparse: call the generic quirk handlers earlyIngo Molnar1-10/+1
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>

2009-01-12x86: fix mpparse.c build error on latest gitJaswinder Singh Rajput1-0/+1

Impact: cleanup, solve 80 columns wrap problems It would be cleaner to rename all the mpf->mpf_X fields to mpf->X - that alone would give 4 characters per usage site.

Impact: cleanup, solve 80 columns wrap problems intel_mp_floating should be renamed to mpf_intel.
