Issue #2711 has been updated by davshao.

File restore_i386_i915.diff added

The attached patch restores i915 drm functionality at least for an i386 Lenovo Ideapad with Intel 945 graphics.  It also should have identical functionality for x86_64 machines.  The patch has been tested for x86_64 Intel integrated graphics G45 and HD Graphics.  Basically the kmap / kunmap functions for i386 only are replaced by the previously used sf_buf functions.

The patch is against
