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

Pull irq fixes from Thomas Gleixner:
"Two fixes for interrupt controller drivers:

- Skip IRQ_M_EXT entries in the device tree when initializing the
RISCV PLIC controller to avoid a double init attempt.

- Use the correct ITS list when issuing the VMOVP synchronization
command so the operation works only on the ITS instances which are
associated to a VM"

irqchip/sifive-plic: Skip contexts except supervisor in plic_init()
