Merge tag 'arc-4.4-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc
Pull ARC fixes from Vineet Gupta:
"Found a couple of brown paper bag bugs with the prev pull request
(including a SMP build breakage report from Guenter). Since these are
urgent I also decided to send over a bunch of other pending fixes
which could have otherwise waited an rc or two.
Summary:
- A bunch of brown paper bag bugs (MAINTAINERS list email, SMP build
failure)
- cpu_relax() now compiler barrier for UP as well
- handling of userspace Bus Errors for ARCompact builds"
* tag 'arc-4.4-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
ARC: Fix silly typo in MAINTAINERS file
ARC: cpu_relax() to be compiler barrier even for UP
ARC: use ASL assembler mnemonic
ARC: [arcompact] Handle bus error from userspace as Interrupt not exception
ARC: remove extraneous header include
ARCv2: lib: memcpy: use local symbols
