Commit eb36c587: new helper: vm_mmap_pgoff()

is causing a build failure:

.../linux/mm/nommu.c: In function 'sys_mmap_pgoff':
.../linux/mm/nommu.c:1489:2: error: 'ret' undeclared (first use in this function)
.../linux/mm/nommu.c:1489:2: note: each undeclared identifier is reported only once for each function it appears in

It looks like it just needs:

diff --git a/mm/nommu.c b/mm/nommu.c
index c4acfbc..d4b0c10 100644

+ retval = vm_mmap_pgoff(file, addr, len, prot, flags, pgoff);
