    sched/idle/x86: Restore mwait_idle() to fix boot hangs, to improve
power savings and to improve performance

    commit b253149b843f89cd300cbdbea27ce1f847506f99 upstream.

    In Linux-3.9 we removed the mwait_idle() loop:

      69fb3676df33 ("x86 idle: remove mwait_idle() and "idle=mwait"
cmdline param")

    The reasoning was that modern machines should be sufficiently
    happy during the boot process using the default_idle() HALT
    loop, until cpuidle loads and either acpi_idle or intel_idle
    invoke the newer MWAIT-with-hints idle loop.

    But two machines reported problems:

     1. Certain Core2-era machines support MWAIT-C1 and HALT only.
        MWAIT-C1 is preferred for optimal power and performance.
        But if they support just C1, cpuidle never loads and
        so they use the boot-time default idle loop forever.

     2. Some laptops will boot-hang if HALT is used,
        but will boot successfully if MWAIT is used.
        This appears to be a hidden assumption in BIOS SMI,
        that is presumably valid on the proprietary OS
        where the BIOS was validated.

           https://bugzilla.kernel.org/show_bug.cgi?id=60770

    So here we effectively revert the patch above, restoring
    the mwait_idle() loop.  However, we don't bother restoring
    the idle=mwait cmdline parameter, since it appears to add
    no value.

    Maintainer notes:

      For 3.9, simply revert 69fb3676df
      for 3.10, patch -F3 applies, fuzz needed due to __cpuinit use in
      context For 3.11, 3.12, 3.13, this patch applies cleanly

Title:
  15.04 will not boot on MacBook 2,1

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  see: http://ubuntuforums.org/showthread.php?t=2274999&p=13286624#post13286624
  Lubuntu 15.04 on refit grub dual boot macbook 2,1 linux-image-3.16 will boot, though
  sometimes hangs but, reboot will work eventually.
  With linux-image-3.19 never,
  ? is the GPU hang reported in kern.log relevant here? i915 problem?
  see kern.log snippet attached
  see error attached from GPU crash dump saved to /sys/class/drm/card0/error

  This seems to be a BUG as suggested by the log:
  "...
  Please file a _new_ bug report on bugs.freedesktop.org against DRI -> DRM/Intel
