From: Andrew Jones <drjones@redhat.com>


We'll add more to this new function in coming patches so we also
state the gic must be created and call it below create_gic().

No functional change intended.

My fault! Very sorry for forgetting to address that in this version.
Shall I re-send this patch with the fix? Or fix it in the next version?

I can wait. It'll be awhile before this series can be merged anyway, since
the KVM patches haven't been merged yet.
