As discussed elsewhere, the patches were modified while applying to resolve conflicts, leading to further conflicts in drm-tip rebuild, and eventually drm-tip build breakage. They would've created further conflicts in linux-next as well as drm-intel-next feature pull (or drm-next backmerge to drm-intel-next). I've gone ahead and reverted the commits from drm-intel-next directly, with Rodrigo's ack. The conflict resolution would have been messy and generated a bunch of extra work, and we needed to get drm-tip build back on track ASAP. We'll need to have a clean baseline to apply the patches on, i.e. drm-misc-next pull request to drm-next, and drm-next backmerge to drm-intel-next.
