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.

Subject: [PATCH] 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.
