Hmm. I am seeing failures on x86_64 on top of Linus's tree
(without this patch)

make -C tools/testing/selftests/memfd/make: Entering directory
`/lkml/linus_git_3.14/tools/testing/selftests/memfd'
gcc -D_FILE_OFFSET_BITS=3D64

-I../../../../arch/x86/include/uapi/ -I../../../../include/uapi/
-I../../../../include/ memfd_test.c -o memfd_test
memfd_test.c: In function =E2=80=98sys_memfd_create=E2=80=99:
memfd_test.c:26:17: error: =E2=80=98__NR_memfd_create=E2=80=99 undeclar=

this function)
  return syscall(__NR_memfd_create, name, flags);
                 ^
memfd_test.c:26:17: note: each undeclared identifier is reported only
once for each function it appears in

Could you please look into this?? It appears __NR_memfd_create isn't
defined on x86_64???

thanks,
