Subject: [PATCH] x86: clean arch/[i386|x86_64] in make mrproper

Applies to: 2.6.24-rc8-git1

For backward compatibility with earlier (< 2.6.24) kernels,
arch/i386/boot/bzImage or arch/x86_64/boot/bzImage
symbolic links to arch/x86/boot/bzImage
are created when you build an x86 kernel.
The arch/i386 or arch/x86_64 directories are then
created for this only purpose.

Issue: these generated directories and symbolic
links are *not cleaned up* when you run
"make mrproper" (and thus "make distclean").
This disturbs the production of patches,
because the source tree is left with generated files
and directories.

Proposed fix: add arch/i386 and arch/x86_84 to
the list of directories cleaned by "make mrproper"

Cleaner solution: stop creating these symbolic
links, but this could cause issues with scripts
still expecting bzImage in arch/i386/boot/bzImage
or in arch/x86_64/boot/bzImage.

What do you think? I can submit another patch for
the second option.

Michael.
