We were reading our 64-bit value in I915_READ64 and returning 32 bits of it. The restoration of fence regs at resume then had a zero end value, and the fence had no effect. Version 2: Split register access functions into per-size versions Sharing code between different sizes seemed reasonable when we only needed a single copy, but as 64-bit access requires its own version, it makes sense to just split them out for each size.
