Hi Andrew, After merging the akpm-current tree, today's linux-next build (powerpc ppc64_defconfig) failed like this: mm/filemap_xip.c:304:2: error: unknown field 'remap_pages' specified in initializer .remap_pages = generic_file_remap_pages, ^ mm/filemap_xip.c:304:17: error: 'generic_file_remap_pages' undeclared here (not in a function) .remap_pages = generic_file_remap_pages, ^ Caused by commit 76f0255272b6 ("mm: drop vm_ops->remap_pages and generic_file_remap_pages() stub"). Looks like one was missed - grep is your friend. I have added this patch for today: From: Stephen Rothwell Date: Mon, 19 Jan 2015 18:16:15 +1100 Subject: [PATCH] mm: drop vm_ops->remap_pages and generic_file_remap_pages() stub fix Signed-off-by: Stephen Rothwell --- mm/filemap_xip.c | 1 - 1 file changed, 1 deletion(-) diff --git a/mm/filemap_xip.c b/mm/filemap_xip.c index 0d105aeff82f..70c09da1a419 100644 --- a/mm/filemap_xip.c +++ b/mm/filemap_xip.c @@ -301,7 +301,6 @@ out: static const struct vm_operations_struct xip_file_vm_ops = { .fault = xip_file_fault, .page_mkwrite = filemap_page_mkwrite, - .remap_pages = generic_file_remap_pages, }; int xip_file_mmap(struct file * file, struct vm_area_struct * vma) -- 2.1.4 -- Cheers, Stephen Rothwell sfr@canb.auug.org.au
