[GIT PULL] Changes for 4.8

[GIT PULL] Changes for 4.8

Hi Linus,

please consider pulling a patch series for 4.8 from:

  https://github.com/jgross1/linux.git tags/for-linus-4-8

Unfortunately 2 of the 6 patches got no Acks as the maintainers didn't
react in spite of multiple pings and resends. The core modification in
the scheduler got an Ack from Peter and multiple tests showed no
regressions.

As the series is touching multiple subsystems I couldn't find anyone
willing to take the series via his tree (I tried Ingo, Thomas, Peter).

Juergen Gross (6):
      xen: sync xen header
      virt, sched: add generic vcpu pinning support
      smp: add function to execute a function synchronously on a cpu
      xen: add xen_pin_vcpu() to support calling functions on a
dedicated pcpu
      dcdbas: make use of smp_call_on_cpu()
      hwmon: use smp_call_on_cpu() for dell-smm i8k

This pull request is lacking any kind of description about why I
should pull and what the patch series actually *does*.

I certainly won't pull just to see what it is it would get me...

Sorry, I didn't comment on this series because the concept seemed
uncontroversial to me: you are trying to extend the virtualization
interface to follow hardware constraints and fix bugs.

PeterZ acked the most critical bits (smp.c) and most of the changes
are on the virtualization side.

So it's fine to me in principle, but I have not looked into finer
details. Can take it into one of the -tip trees if Linus doesn't
pull it for v4.8.

Thanks,

	Ingo

Thanks. I'd appreciate that.

So Linus didn't pull it. Could you take it, please?
