There is a link failure on two of the GPU FYI builders:

The revert failed because at least one dependent change has landed, and I'm not sure how to resolve the conflicts.  Could someone familiar with the code please fix this quickly or create a clean revert?  It's blocking many of the GPU FYI testers.
