Subject: [PATCH v2 0/9] convert hugetlb_cgroup helper functions to folios

This patch series continues the conversion of hugetlb code from being
managed in pages to folios by converting many of the hugetlb_cgroup helper
functions to use folios. This allows the core hugetlb functions to pass in
a folio to these helper functions.

This series depends on my previous patch series which begins the hugetlb
folio conversion[1], both series pass the LTP hugetlb test cases.
