Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull irq updates from Thomas Gleixner: "The irq departement delivers: - Rework the irqdomain core infrastructure to accomodate ACPI based systems. This is required to support ARM64 without creating artificial device tree nodes. - Sanitize the ACPI based ARM GIC initialization by making use of the new firmware independent irqdomain core - Further improvements to the generic MSI management - Generalize the irq migration on CPU hotplug - Improvements to the threaded interrupt infrastructure - Allow the migration of "chained" low level interrupt handlers - Allow optional force masking of interrupts in disable_irq[_nosysnc] - Support for two new interrupt chips - Sigh! - A larger set of errata fixes for ARM gicv3 - The usual pile of fixes, updates, improvements and cleanups all over the place" * 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (71 commits) Document that IRQ_NONE should be returned when IRQ not actually handled PCI/MSI: Allow the MSI domain to be device-specific PCI: Add per-device MSI domain hook of/irq: Use the msi-map property to provide device-specific MSI domain of/irq: Split of_msi_map_rid to reuse msi-map lookup irqchip/gic-v3-its: Parse new version of msi-parent property PCI/MSI: Use of_msi_get_domain instead of open-coded "msi-parent" parsing of/irq: Use of_msi_get_domain instead of open-coded "msi-parent" parsing of/irq: Add support code for multi-parent version of "msi-parent" irqchip/gic-v3-its: Add handling of PCI requester id. PCI/MSI: Add helper function pci_msi_domain_get_msi_rid(). of/irq: Add new function of_msi_map_rid() Docs: dt: Add PCI MSI map bindings irqchip/gic-v2m: Add support for multiple MSI frames irqchip/gic-v3: Fix translation of LPIs after conversion to irq_fwspec irqchip/mxs: Add Alphascale ASM9260 support irqchip/mxs: Prepare driver for hardware with different offsets irqchip/mxs: Panic if ioremap or domain creation fails irqdomain: Documentation updates irqdomain/msi: Use fwnode instead of of_node ...
