2008-10-16xen: Fix bug `do_IRQ: cannot handle IRQ -1 vector 0x6 cpu 1'Alex Nixon
Following commit 9c3f2468d8339866d9ef6a25aae31a8909c6be0d, do_IRQ() looks up the IRQ number in the per-cpu variable vector_irq.

2008-10-16x86: make HAVE_SPARSE_IRQ support selectableYinghai Lu
Ingo said sparse_irq is some intrusive. need to make it selectable to make it simple, remove irq_desc as parameter in some functions. (ack, eoi, set_affinity). may need to make member if irq_chip to take irq_desc, or struct irq later. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>

2008-10-16x86: make 64 handle sis_apic_bug like the 32 bitYinghai Lu
do we have 64bit system with sis chipset? [ mingo@elte.hu: nope, the problem chipset was 32-bit only. The code symmetry is good nevertheless. ] Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16x86: make headers files the same in io_apic_xx.cYinghai Lu

2008-10-16x86: order variables in io_apic_xx.cYinghai Lu

2008-10-16x86: add debug info for 32bit sparse_irqYinghai Lu
so could figure out bugs where we get an interrupt, but vector_irq is not initialized yet. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16x86: make 32bit support per_cpu vectorYinghai Lu
so we can merge io_apic_32.c and io_apic_64.c v2: Use cpu_online_map as target cpus for bigsmp, just like 64-bit is doing. Also remove some unused TARGET_CPUS macro. v3: need to check if desc is null in smp_irq_move_cleanup also migration needs to reset vector too, so copy __target_IO_APIC_irq from 64bit.

2008-10-16x86: make 32 bit to use sparse_irqYinghai Lu
but actually irq still needs to be less than NR_IRQS, because interrupt[NR_IRQS] in entry.S. need to enable per_cpu vector... Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16x86: make 32bit to use irq_2_pin in irq_cfgYinghai Lu

2008-10-16x86: remove irqbalance in kernel for 32 bitYinghai Lu

2008-10-16x86: use 28 bits irq NR for pci msi/msix and htYinghai Lu

2008-10-16x86_64: rename irq_desc/irq_desc_allocYinghai Lu
change names: irq_desc() ==> irq_desc_alloc __irq_desc() ==> irq_desc Also split a few of the uses in lowlevel x86 code. v2: need to check if desc is null in smp_irq_move_cleanup Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16x86: check with without_new in show_interruptsYinghai Lu
so we don't get new one that we don't need it. Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
2008-10-16generic: add irq_desc in function in parameterYinghai Lu
So we could remove some duplicated calling to irq_desc v2: make sure irq_desc in init/main.c is not used without generic_hardirqs Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
