Subject: mm/debug_vm_pgtable: replace pte_mkhuge() with arch_make_huge_pte()
Date: Thu, 2 Mar 2023 17:18:45 +0530
Since the following commit arch_make_huge_pte() should be used directly in
generic memory subsystem as a platform provided page table helper, instead
of pte_mkhuge(). Change hugetlb_basic_tests() to call
arch_make_huge_pte() directly, and update its relevant documentation entry
as required.
