This is not how stuff works in kernel Dmitry, every commit in the
kernel tree should build(at least)/boot fine. Your patch can only be
applied once your base tree has all the patches on which your work is
based of, otherwise this will lead to build failure (stuff like git
bisect breaks with that). It would be better if you take this patch in
5.13, or after 5.12-rc2 once all other stuff lands.
