not sure other's opionions, but personally I wouldn't object to doing
some of this as follow-up patchsets. Ofc my selfish motivation is
that basing atomic on top of primary plane really seems like the right
move, and so sooner we can get the initial parts of this patchset
merged, the sooner we can try to merge atomic ;-)
