2008-07-08x86: update mptable fix with no ioapic v2Yinghai Lu
if the system doesn't have ioapic, we don't need to store entries for mptable update also let mp_config_acpi_gsi not call func in mpparse so later could decouple mpparse with acpi more easily Reported-by: Daniel Exner <dex@dragonslave.de> Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Daniel Exner <dex@dragonslave.de> Cc: Len Brown <lenb@kernel.org> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-08x86: keep MP_intsrc_info untouched if we do not update mptableYinghai Lu
Daniel Exner reported IO-APIC enumeration breakage in linux-next. Alexey Starikovskiy found out that it might be related to commit 2944e16b25 "x86: update mptable". use enable_update_mptable to decide if need check before add mp_irqs array.

2008-07-08x86: clean up reserve_bootmem_generic() and port it to 32-bitYinghai Lu
1. add reserve_bootmem_generic for 32bit 2. change len to unsigned long 3. make early_res_to_bootmem to use it Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-07-08x86: make generic arch support NUMAQ, fix #2Yinghai Lu
we are checking mptable early for numaq, so don't need to reserve_bootmem for it. bootmem is not there yet. do the same thing as 64-bit. found it on 64g above system from 64-bit kernel kexec to 32 bit kernel with numaq support.

2008-07-08x86: add flags parameter to reserve_bootmem_generic()Bernhard Walle
This patch adds a 'flags' parameter to reserve_bootmem_generic() like it already has been added in reserve_bootmem() with commit 72a7fe3967dbf86cb34e24fbf1d957fe24d2f246. It also changes all users to use BOOTMEM_DEFAULT, which doesn't effectively change the behaviour. Since the change is x86-specific, I don't think it's necessary to add a new API for migration. There are only 4 users of that function. The change is necessary for the next patch, using reserve_bootmem_generic() for crashkernel reservation.

2008-06-10x86: make generic arch support NUMAQYinghai Lu
... so it could fall back to normal numa and we'd reduce the impact of the NUMAQ subarch. NUMAQ depends on GENERICARCH also decouple genericarch numa from acpi. also make it fall back to bigsmp if apicid > 8.

2008-06-10x86: introduce max_physical_apicid for bigsmp switchingYinghai Lu
a multi-socket test-system with 3 or 4 ioapics, when 4 dualcore cpus or 2 quadcore cpus installed, needs to switch to bigsmp or physflat. CPU apic id is [4,11] instead of [0,7], and we need to check max apic id instead of cpu numbers. also add check for 32 bit when acpi is not compiled in or acpi=off.

2008-06-03x86: update mptableYinghai Lu
make mptable to be consistent with acpi routing, so we could: 1. kexec kernel with acpi=off 2. work around BIOSes where acpi routing is working, but mptable is not right, so can use kernel/kexec to start other OSes that don't have good acpi support. command line: update_mptable Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-05-25x86: fix mpparse falloutThomas Gleixner
UP builds with LOCAL_APIC=y and IO_APIC=n fail with a missing reference to mp_bus_not_pci. Distangle the mpparse code some more and move the ioapic specific bus check into a separate function. This code needs sume urgent un#ifdef surgery all over the place. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
