Subject[PATCH v2 7/9] mm: Calc the right pfn if page size is not 4K
Date
From: Ma Wupeng <mawupeng1@huawei.com>

Previous 0x100000 is used to check the 4G limit in
find_zone_movable_pfns_for_nodes(). This is right in x86 because
the page size can only be 4K. But 16K and 64K are available in
arm64. So replace it with PHYS_PFN(SZ_4G).
