Ah right, I missed that. I think I originally had some thoughts on it but
didn't immediately comment and then forgot about it. It's basically
ok, so

Acked-by: Arnd Bergmann <arnd@arndb.de>

but please have a look below for a follow-up patch:

A number of the header files that are marked as generic-y in
asm/Kbuild are also marked the same way in uapi/asm/Kbuild.
I think this is a mistake, since we only need one of the two
for each header.

When both exist, we just take the one from asm/, but then we install
the uapi/asm/ version in the 'make headers_install' stage, and they
both have the same contents, so I think you only need the uapi/asm/
version here.

It also seems that the second statement here (for stat.h) is from
an older version, since that header no longer exists, at least if
I'm reading your patches correctly.
