This looks like a change in ABI to me. I think this means you want a new
ioctl so that applications using the existing HAS_RELAXED_FENCING ioctl
and expecting a boolean will continue to work.

This combination looks like a simple bug fix -- not using the new tiling
mode when computing the required alignment. Can you separate out this
