Merge tag 'uapi-prep-20121002' of git://git.infradead.org/users/dhowells/linux-headers
Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build. I have compile tested this with allyesconfig against x86_64, allmodconfig against i386 and a scattering of additional defconfigs of other arches.
