[PATCH v2 03/46] hugetlb: remove redundant pte_mkhuge in migration path
From: James Houghton
Date: Fri Feb 17 2023 - 19:28:59 EST
arch_make_huge_pte, which is called immediately following pte_mkhuge,
already makes the necessary changes to the PTE that pte_mkhuge would
have. The generic implementation of arch_make_huge_pte simply calls
pte_mkhuge.
