Could someone point out the relevance of that patch (in patches/linux-2.6.16.13/). For my eyes it looks just wrong, as it reverts the general effort of not touching per-CPU data of offline CPUs.

top (at least old versions) would crash if the number of online processors changed while they ran. Hence this patch. Not clear it's really a good fix, but it does okay as a workaround.
