In former times, ext4 was enabled implicitely by enabling ext3 but with
the ext3 fs gone, it does not get enabled, which lets devices fail to
mount root on non-initrd based boots with an ext4 root.

I ended up dropping this patch because it conflicted with patches
already in Linus' tree

  c065b6046b34 ("Use CONFIG_EXT4_FS instead of CONFIG_EXT3_FS in all of the defconfigs")

If this is still needed, please respin.
