target/linux/generic/pending-4.14/333-arc-enable-unaligned-access-in-kernel-mode.patch

   1 From: Alexey Brodkin <abrodkin@synopsys.com>
   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.
