I think SMP is a substantial feature of Xen on ARM for 4.3 and it is
therefore worthy of a freeze exception. It touches only ARM specific
code.

Yeah, I think ARM without SMP is almost a bug. :-)  So for this series:

Acked-by: George Dunlap <george.dunlap@xxxxxxxxxxxxx>

I would like to apply Julien's "implement smp_call_function" series[0]
on top of it which fixes reboot/shutdown but which makes the x86
smp_call_function generic and so necessarily touches x86 and generic
code. If that is considered too risky (I personally think it should be
OK, it's a pretty obvious move) then we could duplicate that code for
ARM.

[0] v2 at <1366119508-9227-3-git-send-email-julien.grall@xxxxxxxxxx>

Let me take a look. The most important question is, if there's a bug, will we find it before the release? Since smp_call_function() is called by basically everyone all the time, I think we can be pretty confident that we'll find any bugs in x86 code. Would you agree?
