[PATCH 2/3] mm: thp: Fix the update_mmu_cache() last argument passing in mm/huge_memory.c

[Will Deacon]

From: Catalin Marinas <catalin.marinas@xxxxxxx>

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.
