Yes, that's in mainline now.  There's two bits required to use it which
are (from the driver point of view) fairly orthogonal - one is to
convert the interrupt controller to use the new stuff, the other is to
make sure that all the drivers that are requesting the interrupts over
to threaded IRQ handlers.  genirq will require the threaded handlers
once it's being used.
