Merge branch 'irq-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

Browse source 
Pull irq updates from Thomas Gleixner:
 "The usual pile of boring changes:

   - Consolidate tasklet functions to share code instead of duplicating
     it

   - The first step for making the low level entry handler management on
     multi-platform kernels generic

   - A new sysfs file which allows to retrieve the wakeup state of
     interrupts.

   - Ensure that the interrupt thread follows the effective affinity and
     not the programmed affinity to avoid cross core wakeups.

   - Two new interrupt controller drivers (Microsemi Ocelot and Qualcomm
     PDC)

   - Fix the wakeup path clock handling for Reneasas interrupt chips.

   - Rework the boot time register reset for ARM GIC-V2/3

   - Better suspend/resume support for ARM GIV-V3/ITS

   - Add missing locking to the ARM GIC set_type() callback

   - Small fixes for the irq simulator code

   - SPDX identifiers for the irq core code and removal of boiler plate

   - Small cleanups all over the place"

of a GICv2 controller even if the memory range
exposed by the device tree is too small.
irqchip.gicv3_nolpi=
[ARM, ARM64]
Force the kernel to ignore the availability of
LPIs (and by consequence ITSs). Intended for system
that use the kernel as a bootloader, and thus want
to let secondary kernels in charge of setting up
LPIs.
irqfixup [HW]
When an interrupt is not handled search all handlers
for it. Intended to get systems with badly broken
