    So here's the Broadwell pull request. From a kernel driver pov there's
    two areas with big changes in Broadwell:
    - Completely new enumerated interrupt bits. On the plus side it now looks
      fairly unform and sane.
    - Completely new pagetable layout.
    
    To ensure minimal impact on existing platforms we've refactored both the
    irq and low-level gtt handling code a lot in anticipation of the bdw push.
    So now bdw enabling in these areas just plugs in a bunch of vfuncs.
    
    Otherwise it's all fairly harmless adjusting of switch cases and
    if-ladders to shovel bdw into the right blocks. So minimized impact on
    existing platforms. I've also merged the bdw-stage1 branch into our
    -nightly integration branch for the past week to make sure we don't break
    anything.
    
    Note that there's still quite a flurry or patches floating around, but
    I've figured I'll push this out. I plan to keep the bdw fixes separate
    from my usual -fixes stream so that you can reject them easily in case it
    still looks like too much churn. Also, bdw is for now hidden behind the
    preliminary hw enabling module option. So there's no real pressure to get
    follow-up patches all into 3.13.
