      drm/msm: Fix vmap madv warning · 16eb51ab
      Rob Clark authored
      Commit d6ae7d1c ("drm/msm/gem: Simplify vmap vs LRU tracking")
      introduced a splat in the pin_pages_locked() path for buffers that
      had been MADV_DONTNEED.

      But, as with msm_gem_get_vaddr_active(), this is a special case
      because we know that the buffer won't be purged evicted until it's
      fence is signaled.  We just forgot to propagate the logic get_vaddr()
      to pin_pages_locked().

      drm/msm/atomic: Don't try async if crtc not active · ce902336
      Rob Clark authored
      For a similar reason as commit f2c7ca89 ("drm/atomic-helper: Don't
      set deadline for modesets"), we need the crtc to be already active in
      order to compute a target vblank time for an async commit.  Otherwise
      we get this splat reminding us that we are doing it wrong:
