+From: Alexey Brodkin <abrodkin@synopsys.com>
+Subject: arc: enable unaligned access in kernel mode
+
+This enables misaligned access handling even in kernel mode.
+Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses
+here and there and to cope with that without fixing stuff in the drivers
+we're just gracefully handling it on ARC.
