[PATCH 5/6] hv: Reverse order of resources in hyperv_mmio

From: K. Y. Srinivasan
Date: Wed Mar 09 2016 - 14:57:01 EST


From: Jake Oshins <jakeo@xxxxxxxxxxxxx>

A patch later in this series allocates child nodes
in this resource tree. For that to work, this tree
needs to be sorted in ascending order.
