[RFC PATCH 0/38] clean-up uapi + asm-generic Kbuild files

[Sam Ravnborg]

While working one another patch-set I noticed some stray Kbuild files.
And then when I started to dig into this it somehow got out
of control and I ended up with the following set of patches.

Almost 600 lines chopped of the kernel - which is nice.
But even better is that the Kbuild files for uapi + asm-generic
has become simpler to grok after the clean-up.

The patch-set contains the following major items:

o Fix headers_install for cris - this was trivial to fix
  after uapi support was added.

o Drop a few unused Kbuild files.

o Drop obsolete support for non uapi files in Makefile.headersinst

o Perform a long overdue clean-up of the uapi files.
 The files contained a lot of redundant assignments.

o The last patch introduces include/asm-generic/Kbuild.generic
  This file shall list all asm-generic files that are used by all architectures.
  This makes it much simpler to add a new common asm-generic file.

The patch was broken up in many smaller peices as I wanted to keep the clean-up
patches separate for each architecture to make it easier for arch maintainers to
review/ack their part.

The clean-up patches rely on one of the former patches so they shall
be applied as one serie.
It was done on top of -rc4.

What tree is the best for this stuff?
I would suggest to go via the asm-generic tree that Arnd has.
But it also touches a lot of architectures so Andrews -mm or
kbuild#misc could be used.

The patch-set touches all architectues so I could not copy
all arch maintainers on the mail. Thus I rely on them to read linux-arch.
