Linus,

please pull the latest irq/core branch from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git irq-core-2020-03-30

up to: 8a13b02a010a: Merge tag 'irqchip-5.7' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms into irq/core

Updates for the interrupt subsystem:

Treewide:

- Cleanup of setup_irq() which is not longer required because the
memory allocator is available early. Most cleanup changes come
through the various maintainer trees, so the final removal of
setup_irq() is postponed towards the end of the merge window.

Core:

- Protection against unsafe invocation of interrupt handlers and unsafe
interrupt injection including a fixup of the offending PCI/AER error
injection mechanism.

Invoking interrupt handlers from arbitrary contexts, i.e. outside of
an actual interrupt, can cause inconsistent state on the fragile
x86 interrupt affinity changing hardware trainwreck.

Drivers:

- Second wave of support for the new ARM GICv4.1
- Multi-instance support for Xilinx and PLIC interrupt controllers
- CPU-Hotplug support for PLIC
- The obligatory new driver for X1000 TCU
- Enhancements, cleanups and fixes all over the place

Thanks,

tglx
