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

+          Select this option to enable more accurate task and CPU time
+          accounting.  This is done by reading a CPU counter on each
+          kernel entry and exit and on transitions within the kernel
+          between system, softirq and hardirq state, so there is a
+          small performance impact.  This also enables accounting of

+          than one CPU, say Y.  Note that the kernel does not currently
