    Pull irq updates from Thomas Gleixner:
     "The irq departement proudly presents:
    
       - A rework of the core infrastructure to optimally spread interrupt
         for multiqueue devices. The first version was a bit naive and
         failed to take thread siblings and other details into account.
         Developed in cooperation with Christoph and Keith.
    
       - Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
         active then no further softirq processsing on interrupt return
         happens. Otherwise we try to delegate and still run another batch
         of network packets in the irq return path, which then tries to
         delegate to ksoftirqd .....
    
       - A proper machine parseable sysfs based alternative for
         /proc/interrupts.
    
       - ACPI support for the GICV3-ITS and ARM interrupt remapping
    
       - Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC
    
       - A new irq chip for the JCore (SuperH)
    
       - The usual pile of small fixlets in core and irqchip drivers"
