Subject: [GIT PULL] irqchip updates for Linux 5.1

Hi Thomas,

Here's the set of irqchip and related changes that I've queued for 5.1.
The most interesting change is Julien's pseudo-NMI series, which will be
used on arm64. The rest is the usual set of new interrupt controllers
(Loongson LS1X), feature updates (irqsteer, PLIC, GICv3), and bug fixes
(i8259, PLIC, GICv3).

Please note that the NMI series is also in the arm64 tree, since there is a
dependency between the core code the and architecture-specific backend.

Please pull,

	M.

  irqchip/imx-irqsteer: Add multi output interrupts support (2019-02-22 09:23:46 +0000)

----------------------------------------------------------------
irqchip updates for Linux 5.1

- Core pseudo-NMI handling code
