[PATCH 0/9] Stage-2 huge mappings for pKVM np-guests

Hi all,

This series adds support for stage-2 huge mappings (PMD_SIZE) to pKVM
np-guests, that is installing PMD-level mappings in the stage-2,
whenever the stage-1 is backed by either Hugetlbfs or THPs.

The last patch of that series is an optimization for CMOs using a shared
PMD_SIZE fixmap.
