Earlier without cpuidle framework on pseries, the native arch

We can't rely on Kconfig options to set the fast and slow CPU lists for
HMP scheduling if we want a single kernel
A size of pid depends on a level of pidns and now a level of pidns
is not limited, so it can be more than one page.
Looks reasonable, that it should be limited to a page size. On x86_64
it will allow to create 125 nested pid namespaces. I don't know a
usecase for which, it will be not enough.
