With update of binutils for ARC (this is now based on upstream 2.26)
we noticed issues with loadable kernel modules.
Something like that was happening:
--------------------->8-------------------
mbcache: unknown relocation: 49
insmod: can't insert './mbcache.ko': invalid module format
--------------------->8-------------------
More details could be found in that discussion in binutils mailing list:
http://thread.gmane.org/gmane.comp.gnu.binutils/74662
As of now the simplest work-around is to disable in-kernel unwinder
for now. That will at least allow us to use modules again.

This enables misaligned access handling by software in Linux kernel.
With some wireless drivers (ath9k-htc and mt7601u for example) we see
misaligned accesses here and there and to cope with that without
fixing stuff in the drivers we're just gracefully handling it on ARC.

This switch involved:
[1] Regeneration of config (few options went away)
[2] Regeneration of patches so they apply cleanly (different offsets)
[3] Update of .dts files because we now explicitly specify
memory regions in use as opposed to previously used offset
from 0x8000_0000
