I've so far queued the first 5 patches of this series (basic ACPI
support for GICv3 and associated cleanups). The rest needs additional
discussion (see my comments on patch 10), and requires some form of Ack
from the ACPI maintainers (at least for patch 7).
Thanks Marc!
I will respond to the rest of your comments shortly.
Tomasz
