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