333 | What: The arch/ppc and include/asm-ppc directories | ||
334 | When: Jun 2008 | ||
335 | Why: The arch/powerpc tree is the merged architecture for ppc32 and ppc64 | ||
336 | platforms. Currently there are efforts underway to port the remaining | ||
337 | arch/ppc platforms to the merged tree. New submissions to the arch/ppc | ||
338 | tree have been frozen with the 2.6.22 kernel release and that tree will | ||
339 | remain in bug-fix only mode until its scheduled removal. Platforms | ||
340 | that are not ported by June 2008 will be removed due to the lack of an | ||
341 | interested maintainer. | ||
