| 2 | Subject: arc: enable unaligned access in kernel mode |
| 3 | |
| 4 | This enables misaligned access handling even in kernel mode. |
| 5 | Some wireless drivers (ath9k-htc and mt7601u) use misaligned accesses |
| 6 | here and there and to cope with that without fixing stuff in the drivers |
| 7 | we're just gracefully handling it on ARC. |
