Mostly because I didn't want to regress Power I suppose. The ITMT stuff needs an extra load, whereas the Power stuff can use the CPU number we already have. Also, since we need an interface to pass in this custom list, I don't see the distinction, you can do the same manipulation by constantly updating the prio list. But not of this stuff should be EXPORT'ed, so its only available to the core kernel, which greatly limits the potential for abuse. We can see arch code just fine. And if you spin a custom kernel, you can already wreck the load balancer.
