Hi Masahiro,
what is the reason that the documentation says mandatory-y should only
be used for uapi headers? If would also be very useful for normal
asm-generic headers where most people use the generic version and we
only have a few overrides. Two headers that immediately come to mind
are dma-mapping.h, or msi.h.

Where is it documented?
Documentation/kbuild/makefiles.rst section 7.4 describes
mandatory-y is essentially used by include/(uapi/)asm-generic/Kbuild
include/(uapi/)asm-generic/Kbuild means:
include/uapi/asm-generic/Kbuild
include/asm-generic/Kbuild

Ok, maybe it was just me misreading the documentation. In that
case I'll start submitting patches to use it more.
