Hi Andrew, After merging the akpm tree, today's linux-next build (x86_64 allmodconfig) failed like this: 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' Caused by commit 7f7f03ce3820 ("mm, numa: Implement migrate-on-fault lazy NUMA strategy for regular and THP pages") from the tip tree and expose by commit "x86: convert update_mmu_cache() and update_mmu_cache_pmd() to functions" from the akpm tree. I applied the following patch for today: From: Stephen Rothwell Date: Mon, 10 Dec 2012 19:50:57 +1100 Subject: [PATCH] mm,numa: fix update_mmu_cache_pmd call Fixes 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' Signed-off-by: Stephen Rothwell --- mm/migrate.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/migrate.c b/mm/migrate.c index 5be98e5..964a8c1 100644 --- a/mm/migrate.c +++ b/mm/migrate.c @@ -1663,7 +1663,7 @@ int migrate_misplaced_transhuge_page_put(struct mm_struct *mm, page_add_new_anon_rmap(new_page, vma, haddr); set_pmd_at(mm, haddr, pmd, entry); - update_mmu_cache_pmd(vma, address, entry); + update_mmu_cache_pmd(vma, address, &entry); page_remove_rmap(page); /* * Finish the charge transaction under the page table lock to -- 1.7.10.280.gaa39 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
