[v2,0/2] xen: enhance temporary vcpu pinning

Message

While trying to handle temporary vcpu pinnings in a sane way in my
core scheduling series I found a nice way to simplify the temporary
pinning cases.

I'm sending the two patches independently from my core scheduling
series as they should be considered even without core scheduling.

Changes in V2:
- original patch 1 dropped, as already applied
- new patch 1 removing dead coding and unneeded pinning
- addressed various comments in patch 2
