Merge tag 'arc-fixes-for-4.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc

Pull ARC architecture fixes from Vineet Gupta:
 "Fixes for:

 - perf interrupts on SMP: Not enabled (at boot) and disabled (at runtime)
 - stack unwinder regression (for modules, ignoring dwarf3)
 - nsim hosed for non default kernel link base builds"

* tag 'arc-fixes-for-4.4-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/vgupta/arc:
  ARC: smp: Rename platform hook @init_cpu_smp -> @init_per_cpu
  ARC: rename smp operation init_irq_cpu() to init_per_cpu()
  ARC: dw2 unwind: Ignore CIE version !=1 gracefully instead of bailing
  ARC: dw2 unwind: Reinstante unwinding out of modules
  ARC: [plat-sim] unbork non default CONFIG_LINUX_LINK_BASE
  ARC: intc: Document arc_request_percpu_irq() better
  ARCv2: perf: Ensure perf intr gets enabled on all cores
  ARC: intc: No need to clear IRQ_NOAUTOEN
  ARCv2: intc: Fix random perf irq disabling in SMP setup
  ARC: [axs10x] cap ethernet phy to 100 Mbit/sec
