Subject: mm/migrate: drop pte_mkhuge() in remove_migration_pte()
Date: Thu, 2 Mar 2023 08:23:49 +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().  This just drops pte_mkhuge() from
remove_migration_pte(), which has now become redundant.
