Bug #3021: sys/dev/drm/i915/i915_gem_stolen.c:115]: (error) Signed integer overflow for expression '65535<<20'
http://bugs.dragonflybsd.org/issues/3021#change-14752

* Author: dcb
* Status: Resolved
* Priority: Normal
* Target version: 6.4
* Start date: 2017-04-11
----------------------------------------
Source code is

        base = bsm & BSM_MASK;

but

$ fgrep BSM_MASK `find dragonfly/sys/dev -name \*.h -print` 
dragonfly/sys/dev/drm/i915/i915_reg.h:#define   BSM_MASK (0xFFFF << 20)
$

Macro BSM_MASK seems to be 36 bits wide, which won't fit into a 32 bit int.
