Subject[PATCH 2/3] mm: thp: Fix the update_mmu_cache() last argument passing in mm/huge_memory.c
Date
From: Catalin Marinas <catalin.marinas@arm.com>

The update_mmu_cache() takes a pointer (to pte_t by default) as the last
argument but the huge_memory.c passes a pmd_t value. The patch changes
the argument to the pmd_t * pointer.
