      PCI/MSI: Rename mask/unmask_msi_irq treewide · 280510f1
      由 Thomas Gleixner 提交于 
      The PCI/MSI irq chip callbacks mask/unmask_msi_irq have been renamed
to pci_msi_mask/unmask_irq to mark them PCI specific. Rename all usage
sites. The conversion helper functions are kept around to avoid
conflicts in next and will be removed after merging into mainline.

Coccinelle assisted conversion. No functional change.

      x86: irq: Fix bug in setting IOAPIC pin attributes · f395dcae
      由 Jiang Liu 提交于 
      Commit 15a3c7cc "x86, irq: Introduce two helper functions
to support irqdomain map operation" breaks LPSS ACPI enumerated
devices.

On startup, IOAPIC driver preallocates IRQ descriptors and programs
IOAPIC pins with default level and polarity attributes for all legacy
IRQs. Later legacy IRQ users may fail to set IOAPIC pin attributes
if the requested attributes conflicts with the default IOAPIC pin
attributes. So change mp_irqdomain_map() to allow the first legacy IRQ
user to reprogram IOAPIC pin with different attributes.

      x86, irq: Introduce helper functions to release IOAPIC pin · df334bea
      由 Jiang Liu 提交于 
      Introduce function mp_unmap_irq() to release IOAPIC IRQ when IRQ is not
used any more, which will typically called by pcibios_disabled_irq.

And function mp_irqdomain_unmap() is a common implementation of
irq_domain_ops.unmap for IOAPIC.

      x86, irq: Simplify the way to handle ISA IRQ · 16ee7b3d
      由 Jiang Liu 提交于 
      On startup, setup_IO_APIC_irqs() will program all IOAPIC pins for ISA
IRQs. Later when mp_map_pin_to_irq() is called, it just returns ISA IRQ
number without programming corresponding IOAPIC pin.

This patch consolidates the way to program IOAPIC pins for both ISA and
non-ISA IRQs into mp_map_pin_to_irq() as below:
1) For ISA IRQs, mp_irqs array is used to map IOAPIC pin to IRQ and
   mp_irqdomain_map() is used to actually program the pin.
2) For non-ISA IRQs, irqdomain is used to map IOAPIC pin to IRQ, and
   mp_irqdomain_map() is also used to actually program the pin.
