Subject: [PATCH 00/10] UAPI: Fixes
Hi Linus,
Here are some UAPI fixes for you. They can be found in git at:
git://git.infradead.org/users/dhowells/linux-headers.git
on the uapi-fixes branch at the uapi-fixes-20121017 tag.
They do a number of things:
(1) Import a patch from Catalin Marinas to extend the generic-y in Kbuild
facility to uapi directories.
(2) Make arch/tile's ucontext.h file use (1) and remove the header-y line
from the kernel internal side of things.
(3) Remove some now-empty conditional bits from include/linux/Kbuild. The
contents got moved to the UAPI side of things along with new
conditionals.
(4) Deal with now-empty files:
(a) Empty Kbuild files under include/ get removed.
(b) Empty Kbuild files under arch/ get comments to hold them as they are
likely to end up with generic-y or genhdr-y lines. Deleting them
appears to work if we want to go that route.
(c) Put a comment into uapi/asm-generic/kvm_para.h to prevent the patch
program from deleting that, and made the arches with empty kvm_para.h
uapi files use that instead of having their own files.
(d) Put comments into four other empty uapi/ headers to prevent the patch
program from deleting them.
A question: Is this the right way to deal with the now-empty Kbuild files?
The ones under include/ are unlikely to be used - even for generated files, I
think - so getting rid of them is probably okay. Once all the bits are in, we
can probably remove all the Kbuild files under include/ that aren't also under
include/uapi/.
The ones under arch/ are more of an issue because of the potential for
generic-y and genhdr-y.
