The overlayfs has started enforcing a maximum file size, but is missing
the header file that defines the PAGE_CACHE_SIZE constant in some
configurations.

fs/overlayfs/super.c: In function 'ovl_fill_super':
fs/overlayfs/super.c:939:29: error: 'PAGE_CACHE_SIZE' undeclared (first use in this function)

The patch that introduced this was marked for stable, so I'm marking this
the same way.
