Simplify the way to print IOAPIC entry content, so we can remove native_io_apic_print_entries(), intel_ir_io_apic_print_entries() and x86_io_apic_ops.print_entries() later. Folded a patch from Thomas to fix errors in printed pin attributes, http://www.spinics.net/lists/linux-tip-commits/msg26108.htmlSigned-off-by:

To support legacy ISA IRQs, we need to preallocate irq_cfg structures for legacy ISA IRQs. Refine the way to allocate irq_cfg for legacy ISA IRQs, so it's more friendly for the hierarchical irqdomain implementation. Signed-off-by:

MID has no PIC, but depending on the platform it requires the abt_timer, which is connected to irq0. The timer is set up at late_time_init(). But, looking at the MID code it seems, that there is no reason to do so. The only code which might need the timer working is the TSC calibration code, but thats a non issue on MID as that is using its own empty calibration function. And check_timer() is not invoked either because MID has no PIC and therefor no legacy irqs. So if you look at intel_mid_time_init() then you'll see that in the ARAT case the timer setup is skipped already. So until the point where x86_init.timers.setup_percpu_clockev() is called for the boot cpu nothing really needs a timer on MID. According to the MID code the apbt horror is only used for moorestown. Medfield and later use the local apic timer without the apbt nonsense. The best thing we can do is to drop moorestown support and get rid of that apbt nonsense alltogether. I don't think anyone deeply cares about it not being supported from 3.18 on. The number of devices which sport a moorestown should be pretty limited and the only relevant use case of those is to act as a pocket heater with short battery life time. Its pretty pointless to update kernels on pocket heaters except for bragging reasons. If someone at Intel really thinks that we need to keep moorestown alive for other than documentary and sentimental reasons, then we can move the apbt setup to x86_init.timers.setup_percpu_clockev(). At that point the IOAPIC is setup already, so it should just work. Signed-off-by:

We construct hwirq based on mmr_blade and mmr_offset, but mmr_offset has type unsigned long, it may exceed the range of irq_hw_number_t.

Introduce new interfaces for interrupt remapping drivers to support hierarchical irqdomains: 1) irq_remapping_get_ir_irq_domain(): get irqdomain associated with an interrupt remapping unit. IOAPIC/HPET drivers use this interface to get parent interrupt remapping irqdomain. 2) irq_remapping_get_irq_domain(): get irqdomain for an IRQ allocation. This is mainly used to support MSI irqdomain. We must build one MSI irqdomain for each interrupt remapping unit. MSI driver calls this interface to get MSI irqdomain associated with an IR irqdomain which manages the PCI devices. In a further step we will store the irqdomain pointer in the device struct to avoid this call in the irq allocation path. Architecture specific hooks: 1) arch_get_ir_parent_domain(): get parent irqdomain for IR irqdomain, which is x86_vector_domain on x86 platforms. 2) arch_create_msi_irq_domain(): create an MSI irqdomain associated with the interrupt remapping unit. We also add following callbacks into struct irq_remap_ops: struct irq_domain *(*get_ir_irq_domain)(struct irq_alloc_info *); struct irq_domain *(*get_irq_domain)(struct irq_alloc_info *); Once all clients of IR have been converted to the new hierarchical irqdomain interfaces, we will: 1) Remove set_ioapic_entry, set_affinity, free_irq, compose_msi_msg, msi_alloc_irq, msi_setup_irq, setup_hpet_msi from struct remap_osp 2) Remove setup_ioapic_remapped_entry, free_remapped_irq, compose_remapped_msi_msg, setup_hpet_msi_remapped, setup_remapped_irq. 3) Simplify x86_io_apic_ops and x86_msi. We can achieve a way clearer architecture with all these changes applied. Signed-off-by:

Use new irqdomain interfaces to allocate/free IRQ for DMAR and interrupt remapping, so we can remove GENERIC_IRQ_LEGACY_ALLOC_HWIRQ later. The private definitions of irq_alloc_hwirqs()/irq_free_hwirqs() are a temporary solution, they will be removed once we have converted the interrupt remapping driver to use irqdomain framework.
