Subject: lib: Disable MI_STORE_DATA_IMM for gen3 (i915g and i915gm)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The early gen3 machines inherited the MI block and restrictions from
gen2, and may only use physical addresses in conjunction with
MI_STORE_DATA_IMM -- that makes it unusable for us from userspace, where
we can only use virtual offsets.
