Move the SEAD-3 device-tree to arch/mips/boot/dts/mti/ and update the
Makefiles accordingly. Since SEAD-3 requires the device-tree to be
built into the kernel, select BUILTIN_DTB when building for SEAD-3.

Move the Octeon device-trees to arch/mips/boot/dts/cavium-octeon/ and
update the Makefiles accordingly. Since Octeon requires the device-tree
to be built into the kernel, select BUILTIN_DTB as well.

In preparation for moving the device-trees to a common location,
introduce the config option BUILTIN_DTB, which can be selected by
platforms that use a device-tree built into the kernel image, and
create a Makefile to build the device-trees in arch/mips/boot/dts/.

To be consistent with other architectures and to avoid unnecessary
makefile duplication, move all MIPS device-trees to arch/mips/boot/dts
and build them with a common makefile. Per Olof's suggestion in v1,
device-trees are grouped into per-vendor subdirectories. Note that

Hi Chao,
I agree it's correct unlock_new_inode should be located after make_bad_inode.
About this scenario,
I think we should check some condition if this could be occured;
A inode allocated newly could be victim by gc thread.
Then, f2fs_iget called by Thread A have to fail because we handled it
The else condition is redundant after a return. Remove these redundant else
conditions.

Things do not migrate to mmotm (and hence linux-next) very quickly
