- Subject: [PATCH 0/2] irqchip/gic-v3-its: LPI tables fixes
By staring at the code (while writing the ITS driver for Xen) I
stumbled upon two minor things that deserve fixing:
Patch 1 checks whether LPIs are really disabled before setting up the
tables, as the architecture actually disallows clearing the LPI enable
bit. We try this anyway, but bail out if this fails.
Patch 2 makes sure we don't miss when the redistributors denies our
cacheable mapping request.
Please have a look and apply if that makes sense.

irqchip/gic-v3-its: bail out on already enabled LPIs
irqchip/gic-v3-its: always check for cacheability attributes
