[GIT PULL] User-API header split preliminary patches

[GIT PULL] User-API header split preliminary patches

[David Howells]

Hi Linus,

Can you pull these patches from my GIT repository please?

They prepare the way for splitting out the User API definitions from the
standard kernel internal headers into their own header file directories (there
will be arch-specific directories as well as the common ones).

They have been in linux-next for roughly three weeks.

I have audited them from my initial patch submission to get rid of patches
that are no longer necessary.

I have also built allyesconfig with all the cross-compilers I can create on
the full patch spectrum (on the uapi-split branch in the same tree) and
eliminated the problems created.

Can you please consider pulling the further patchset that actually performs
the split at the end of the merge window.  It *will* need regenerating
whenever it is pulled, but is mostly scripted.

Thanks,
David

Pulling the rest of the User-API header split patches

[David Howells]

Hi Linus,

Thanks for pulling the User-API header split preliminary patches.

Will you be pulling the rest of the patches to actually perform the split at
the end of this merge window?  If so, as previously mentioned, I'll need to
regenerate them before you do.

However, for the moment, I dropped the preliminary patches from my tree and
regenerated the rest based on the tree I saw this morning:

http://git.infradead.org/users/dhowells/linux-headers.git/shortlog/refs/heads/uapi-split

I've made 'make allyesconfig' build again on x86_64.  arch/x86/lib/insn.c is
compiled for use in both userspace and kernelspace, necessitating a bit of
#include adjustment, but that was the only necessary change.  I've also had
Dave Airlie review the preparatory DRM patches and those have been adjusted.

An opinion, if I may: I have been checking the scripts into the GIT tree (with
the intention to delete them later) so that a record of them is retained - but
I wonder if I should bother...  Hopefully, once the scripts are run and the
results applied, it won't be necessary to retain the scripts.

Thanks,
David
