Subject: irqchip/gic-v3-its: Track per-ITS list number
Patch-mainline: v4.15-rc1
Git-commit: debf6d02bb58a099202375ca2ba88e9775b153c6
References: FATE#323954
At boot time, we enumerate all the GICv4-capable ITSs, and build
a mask of the available ITSs. Take this opportunity to store
the ITS number in the its_node structure so that we can use it
at a later time.
