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