There are some clean-up/improvement work that can be done in the Arm P2M code triggered by [1] and [2]. These were found at the 4.17 code freeze period so the issues were not fixed at that time. Therefore do the follow-ups here.
Patch#1 addresses one comment in [1]. It was sent earlier and reviewed once. Pick the updated version, i.e. "[PATCH v2] xen/arm: Reduce redundant clear root pages when teardown p2m", to this series. Patch#2 and #3 addresses the comment in [2] following the discussion between two possible options.
