Hello there,

Recent versions of gcc say this:

include/drm/i915_drm.h:96:34: warning: result of ‘65535 << 20’ requires 37 bits to represent, but ‘int’ only has 32 bits [-Wshift-overflow=]

Source code is

#define INTEL_BSM_MASK (0xFFFF << 20)

Maybe something like

#define INTEL_BSM_MASK (0xFFFFUL<< 20)

might be better.

Yup. Care to bake this into a patch (with s-o-b and everything per Documentation/SubmittingPatches) so I can apply it? -Daniel
