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
