Pull ARC fixes from Vineet Gupta: "Hopefully last set of changes for ARC for 4.10: - fix for unaligned access emulation corner case - fix for udelay loop inline asm regression - fix irq affinity finally for AXS103 board [Yuriy] - final fixes for setting IO-coherency sanely in SMP" * tag 'arc-4.10-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc: ARC: [arcompact] handle unaligned access delay slot corner case ARCv2: smp-boot: wake_flag polling by non-Masters needs to be uncached ARC: smp-boot: Decouple Non masters waiting API from jump to entry point ARCv2: MCIP: update the BCR per current changes ARC: udelay: fix inline assembler by adding LP_COUNT to clobber list ARCv2: MCIP: Deprecate setting of affinity in Device Tree
