Merge tag 'kbuild-uapi-v4.12' of git://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild
Pull Kbuild UAPI updates from Masahiro Yamada:
"Improvement of headers_install by Nicolas Dichtel.
It has been long since the introduction of uapi directories, but the
de-coupling of exported headers has not been completed. Headers listed
in header-y are exported whether they exist in uapi directories or
not. His work fixes this inconsistency.
All (and only) headers under uapi directories are now exported. The
asm-generic wrappers are still exceptions, but this is a big step
forward"
