looks good, applied to tip/x86/core, thanks!

it's too late for v2.6.27 (and not a serious regression anyway), but i 
marked it for .27.1 backporting.

Your other patch still makes sense - as additional_cpus is an existing 
boot parameter it can be specified at .config time as well. You should 
not enable it in a distro kernel though, if you intend to support real 
hotplug CPU hardware. (which is extremely rare btw.)
