That's a fixed hunk for 4.9:

Indeed EzChip's nps400 platform was added later but we don't need it in 4.4.y
as IIRC there were quite some other dependencies, so just drop hunk related to it.

And once nps_defconfig hunk is dropped there's a fixd hunk for arch/arc/Makefile
similarly to 4.9:

Hope above helps. Otherwise I may send complete patches for both
4.4 and 4.9.

Let me know what is your preference.
