In v4.12-rc1, we had a big progress for headers_install.
All (and only) headers under UAPI directories are exported.
However, asm-generic wrappers are still exceptions because
most of arch/*/include/asm/Kbuild include "generic-y" for
exported headers. As a result, many of generic-wrappers to be
exported are generated outside UAPI directories.
To finish de-coupling UAPI, "generic-y" for exported headers
should be moved to arch/*/include/uapi/asm/Kbuild.
With those cleanups, the logic of headers_install will become
even simpler. UAPI will be completely self-contained.
This series is based on v4.12-rc2 tag.
This series touches Kbuild files under arch/. We have two options
to merge this series.
[1] I will collect Acked-by from arch maintainers, then apply the
whole series to the Kbuild tree.
[2] I will ask arch maintainers to pick up arch changes (for v4.13),
then apply Makefile changes to the Kbuild tree (for v4.14).
[1] will finish this work by v4.13, but need to deal with some conflicts.
[2] will allow us to reduce conflicts (still a bit conflicts),
but take more time to finish this work.
If arch maintainers ack [1], I can manage conflicts
before sending a pull request to Linus.
