Hi Bruce,
Currently without THP being enabled, MAX_ORDER via FORCE_MAX_ZONEORDER gets
reduced to 11, which falls below HUGETLB_PAGE_ORDER for certain 16K and 64K
page size configurations. This is problematic which throws up the following
warning during boot as pageblock_order via HUGETLB_PAGE_ORDER order exceeds
MAX_ORDER.
This patch solves the problem via keeping FORCE_MAX_ZONEORDER unchanged
with or
without THP on 16K and 64K page size configurations, making sure that the
HUGETLB_PAGE_ORDER (and pageblock_order) would never exceed MAX_ORDER.
Please help to merge this patch to our linux-yocto repo.
repo:

branch:
v5.10/standard/base
Thanks,
Ruiqiang
