This commit is the first one that breaks Xorg startup for my setup:
GTX 1080 + Dell UP2414Q (4K DP MST monitor).

I believe this is the crucial part of dmesg (full dmesg is attached):

[   29.997140] [drm:nouveau_framebuffer_new] Unsupported modifier: 0x300000000000014
[   29.997143] [drm:drm_internal_framebuffer_create] could not create framebuffer
[   29.997145] [drm:drm_ioctl] pid=3393, ret = -22

Any suggestions?
