[PATCH] Generated files destruction

[PATCH] Generated files destruction

[Rusty Russell]

Linus, please apply.

	I would like to start migrating all build-generated files to
names matching "generated*" or ".generated*", esp. those which look
like source files.  This is mainly for readability and for simplicity
when diffing built kernel trees.  I'll be encouraging various
maintainers who generate (.c, .h and .s) files which are not meant to
be shipped with the kernel source to migrate, in my copious free
time...

Cheers!
Rusty.

I think the proper solution here is actually separate obj/src dirs, 
instead of special names. It's actually quite easy to get that implemented 
in the current kbuild, I just didn't find the time for proper testing yet. 
I'll have a patch ready for testing soon, though.

Sure, if it basically comes for free.  Otherwise, I don't see any
attraction in separating them: cp -al linux-2.5.34 working-2.5.34-foo
takes a couple of seconds.

Cheers!

Please keep in mind that some people (at least me) don't like separate
build trees - I do all the "real work" in the source directory, and if I
need to go somewhere else to build, that's just a pain (and it's another
pain if, once I'm building, I have to use a different path than the one
that I'm used to in the source directory to fix something).

So I want to keep the mixed tree around (which is not to say that people 
who like the separate-object-tree thing shouldn't be _able_ to use it).
