From ce4a9cc579381bc70b12ebb91c57da31baf8e3b7 Mon Sep 17 00:00:00 2001 From: Stephen Rothwell Date: Mon, 10 Dec 2012 19:50:57 +1100 Subject: [PATCH] mm,numa: fix update_mmu_cache_pmd call This build error is currently hidden by the fact that the x86 implementation of 'update_mmu_cache_pmd()' is a macro that doesn't use its last argument, but commit b32967ff101a ("mm: numa: Add THP migration for the NUMA working set scanning fault case") introduced a call with the wrong third argument. In the akpm tree, it causes this build error: mm/migrate.c: In function 'migrate_misplaced_transhuge_page_put': mm/migrate.c:1666:2: error: incompatible type for argument 3 of 'update_mmu_cache_pmd' arch/x86/include/asm/pgtable.h:792:20: note: expected 'struct pmd_t *' but argument is of type 'pmd_t' Fix it.
