Generated files destruction

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).
