Wrt https://bugs.freedesktop.org/show_bug.cgi?id=97139 this is a
regression and I'll ack the revert. Yes, we need to resolve exactly how
we get a stall between intel_hdmi_detect() and pageflip/cursor, but the
onus is on the submitter of the patch to fix existing issues first to
prevent such regressions (if possible, or else mitigate them).
