linux-next: build failure after merge of the userns tree

Hi Eric,

After merging the userns tree, today's linux-next build (powerpc
ppc64_defconfig) failed like this:

fs/namei.c: In function 'covered':
fs/namei.c:3528:2: error: too many arguments to function '__lookup_mnt'
is_covered = d_mountpoint(dentry) && __lookup_mnt(mnt, dentry, 1);
^

Caused by my incomplete merge resolution between commits 474279dc0f77
("split __lookup_mnt() in two functions") from the vfs tree and
a3b4491433f2 ("vfs: Don't allow overwriting mounts in the current mount
namespace") from the userns tree.

I added the following fix up patch:
