Subject: mm: thp: fix the update_mmu_cache() last argument passing in mm/huge_memory.c
X-Git-Tag: next-20121005~1^2~226
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a2cb72e9103fef538b119a5d8e304255f835b580;p=karo-tx-linux.git

mm: thp: fix the update_mmu_cache() last argument passing in mm/huge_memory.c

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.
