      Revert "drm/i915: enable rc6 by default" · 05bd4268
      Keith Packard 提交于
      This reverts commit a51f7a66.
      
      We still have a few Ironlake and Sandybridge machines which fail when
      RC6 is enabled. Better luck next release?

      drm/i915: Clean up i915_driver_load failure path · a7b85d2a
      Keith Packard 提交于
      i915_driver_load adds a write-combining MTRR region for the GTT
      aperture to improve memory speeds through the aperture. If
      i915_driver_load fails after this, it would not have cleaned up the
      MTRR. This shouldn't cause any problems, except for consuming an MTRR
      register. Still, it's best to clean up completely in the failure path,
      which is easily done by calling mtrr_del if the mtrr was successfully
      allocated.
      
      i915_driver_load calls i915_gem_load which register
      i915_gem_inactive_shrink. If i915_driver_load fails after calling
      i915_gem_load, the shrinker will be left registered. When called, it
      will access freed memory and crash. The fix is to unregister the shrinker in the
      failure path using code duplicated from i915_driver_unload.
      
      i915_driver_load also has some incorrect gotos in the error cleanup
      paths:
      
       * After failing to initialize the GTT (which cannot happen, btw,
         intel_gtt_get returns a fixed (non-NULL) value), it tries to
         free the uninitialized WC IO mapping. Fixed this by changing the
         target from out_iomapfree to out_rmmap

      hwmon: (pmbus) Use long variables for register to data conversions · f450c150
      Guenter Roeck 提交于
      Using integer variable types for register to data conversions can cause
      overflows especially for power calculations, which are in microwatt.
      Use long variables instead.
