  on Apple MacBookPro laptops with dual GPUs and the gmux chip. The
  reason is that whereas formely drm_init_pdev() and drm_fill_pdev()
  where mere bookkeeping routines, the above commit relocates
  assignment of irq from drm_drv.c:drm_attach() to drm_fill_pdev().
  Since apple_gmux is loaded before i915, and apple_gmux initializes
  a pdev structure including an irq for the graphics pci device, the
  i915 which is loaded afterwards will get zero for an irq and hence
  fails to attach.

* The temporary fix is to disable apple_gmux initializing a pci_dev
  structure for bookkeeping purposes. This is not needed at the

* When and if the initialization of graphics pci devices becomes

  schedule overloaded threads onto other cores, but this operation
  was being executed on all cores simultaneously which throws the
  uload/ucount metrics into an unstable state, causing threads to
  bounce around longer the necessary.

  Fix by round-robining the operation based on something similar to
  sched_ticks % cpuid.

  This significantly improves heavy multi-tasking performance on systems
  with many cores.

* Add memory-on-node weighting to the scheduler.  This detects asymetric
  NUMA configurations for situations where not all DIMM slots have been
  populated, and for CPUs which are naturally assymetric such as the
  2990WX which only has memory directly connected to two of its four

  This change will preferentially schedule threads onto nodes with
  greater amounts of attached memory under light loads, and dig into
  the less desirable cpu nodes as the load increases.
