From 86ea9c51b9bc4db363a1cb2bfc2b001260eb6e1f Mon Sep 17 00:00:00 2001 From: David Daney <david.daney@cavium.com> Date: Fri, 18 Jan 2013 18:16:40 +0000 Subject: MIPS: Fix build failure by adding definition of pfn_pmd(). With CONFIG_TRANSPARENT_HUGEPAGE=y and CONFIG_HUGETLBFS=y we get the following build failure: CC mm/huge_memory.o mm/huge_memory.c: In function 'set_huge_zero_page': mm/huge_memory.c:780:2: error: implicit declaration of function 'pfn_pmd' [-Werror=implicit-function-declaration] mm/huge_memory.c:780:8: error: incompatible types when assigning to type 'pmd_t' from type 'int' Add a definition of pfn_pmd() for 64-bit kernels (the only place huge pages are currently supported).
