This patch bumps the 4.4 kernel from .28 to .30 and refreshes the patches. Compile-tested on ar71xx, x86/64, ramips/mt7621, brcm47xx and kirkwood. Run-tested on ar71xx & ramips/mt7621, brcm47xx and kirkwood (last two confirmed by P. Wassi). Signed-off-by: Stijn Segers <francesco.borromini@inventati.org>
