Revert "drm/i915: Avoid stalling on pending flips for legacy cursor updates" "drm/i915: Allow nonblocking update of pageflips" should have been split up, misses a proper commit message and seems to cause issues in the legacy page_flip path as demonstrated by kms_flip. "drm/i915: Make unpin async" doesn't handle the unthrottled cursor updates correctly, leading to an apparent pin count leak. This is caught by the WARN_ON in i915_gem_object_do_pin which screams if we have more than DRM_I915_GEM_OBJECT_MAX_PIN_COUNT pins. Unfortuantely we can't just revert these two because this patch series came with a built-in bisect breakage in the form of temporarily removing the unthrottled cursor update hack for legacy cursor ioctl. Therefore there's no other option than to revert the entire pile :( There's one tiny conflict in intel_drv.h due to other patches, nothing serious. Normally I'd wait a bit longer with doing a maintainer revert, but since the minimal set of patches we need to revert (due to the bisect breakage) is so big, time is running out fast. And very soon (especially after a few attempts at fixing issues) it'll be really hard to revert things cleanly. Lessons learned: - Not a good idea to rush the review (done by someone fairly new to the area) and not make sure domain experts had a chance to read it. - Patches should be properly split up. I only looked at the two patches that should be reverted in detail, but both look like the mix up different things in one patch. - Patches really should have proper commit messages. Especially when doing more than one thing, and especially when touching critical and tricky core code. - Building a patch series and r-b stamping it when it has a built-in bisect breakage is not a good idea. - I also think we need to stop building up technical debt by postponing atomic igt testcases even longer. I think it's clear that there's enough corner cases in this beast that we really need to have the testcases _before_ the next step lands. (cherry picked from commit5a21b6650a
