Addresses in the command streams should be in canonical form (i.e
bit[63:48] == bit[47]). If the [bo->gtt_offset, bo->gtt_offset +
target_offset] range contains the address 0x800000000000, the current
code will fail that criteria.
Fixes: 1c9053d0765dc6 ("i965: Prepare batchbuffer module for softpin support.")

This was Rb by Ken on IRC.
Waiting for some CI to comeback before pushing.
