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.
