[RFC][PATCH 0/4] sched,numa: pinned task accounting

[Peter Zijlstra]

Hi,

Here's a first few patches that provide pinned task accounting; they are boot
tested only so far.

I don't think this is enough to address Artem's regression, but its a
foundation to add some more smarts. In particular we should make it harder
still to migrate well placed tasks away due to these pinned tasks.

Rostedt, Juri, please double check what I did to your resp. set_cpus_allowed
methods.
