[Patch Part1 v8 19/37] iommu/vt-d: Refine the interfaces to create IRQ for DMAR unit

Refine the interfaces to create IRQ for DMAR unit. It's a preparation for converting DMAR IRQ to hierarchy irqdomain on x86. It also moves dmar_alloc_hwirq()/dmar_free_hwirq() from irq_remapping.h to dmar.h. They are not irq_remapping specific. Signed-off-by: Jiang Liu jiang@linux.intel.com

[Patch Part1 v8 08/37] irq_remapping: Introduce new interfaces to support hierarchy irqdomain

Introduce new interfaces for interrupt remapping drivers to support hierarchy irqdomain: 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)

[Patch Part1 v8 07/37] x86/dmar: Use new irqdomain interfaces to allocate/free IRQ

Use new irqdomain interfaces to allocate/free IRQ for DMAR and interrupt remapping, so we could kill GENERIC_IRQ_LEGACY_ALLOC_HWIRQ later. The private definition of irq_alloc_hwirqs()/irq_free_hwirqs() are temporary solution, it will be removed once we have converted interrupt remapping driver to
