Stefano, let me know the new helper corresponds to change you requested

This patch is a bug fix for Xen 4.7. Without it, a MMIO register and
sysreg will be set to a random value (actually PC) when the zero
register is used.

I'm not sure if we should consider this patch to be backported to Xen
4.6 and Xen 4.5. It depends on other patches and it would require some
rework to backport it alone.


So the tags and alike would suggest this is ready to be committed,
but the lack of a version number or version history don't really
help support this. Could you please clarify the state of this patch?

Sorry I forgot to mention the changes I made. This is a resend with the modification suggested by Stefano.

I've kept Stefano's reviewed-by as he was fine with and without the helpers. Although, I would like to give Stefano a chance to object. Can you wait a bit before committing?
