This series contains:

1. The first patch from Andrew that reworks p2m_init() so that
fallible operations in p2m_init() will not lead to leakage of VMID
or the root table.
2. The patch in [1] rebased on top of the p2m_init() rework that
populate default 16 pages to the p2m pool for the mapping of GICv2
at the domain creation stage.
