You need to have the full thing ready with kernel, igt, libdrm, and
umd driver patches (and maybe even testcases for the new umd feature,
e.g. for some of the arb robustness stuff we've done). Then you post
them all to relevant mailing lists and go through the review process
for all parts. Once that's done and _all_ parts are reviewed, merging
starts with kernel+igt, then libdrm + libdrm release, then umd.
