For some ARM64 cores there is a facility that allows the page
table walker to track the dirty state of a page. These commits
enhances the performance of CMOs by VA.
Marc Zyngier (2):
arm64: Use FEAT_HAFDBS to track dirty pages when available
arm64: Use level-2 for largest block mappings when FEAT_HAFDBS is
present
meitao (1):
armv8: enable HAFDBS for other ELx when FEAT_HAFDBS is present
