This series is a mix of bug fixes, cleanup and new support in KVM's handling of huge pages. The series initially stemmed from a syzkaller bug report[1], which is fixed by patch 02, "mm: thp: KVM: Explicitly check for THP when populating secondary MMU". While investigating options for fixing the syzkaller bug, I realized KVM could reuse the approach from Barret's series to enable huge pages for DAX mappings in KVM[2] for all types of huge mappings, i.e. walk the host page tables instead of querying metadata (patches 05 - 09).
Thanks, Sean. I tested this patch series out, and it works for me. (Huge KVM mappings of a DAX file, etc.).
Thanks, Barret
