When searching for runs to reclaim, we need to ensure that the entire run will be added to the buddy allocator as a single unit. Otherwise, it will not be visible to vm_phys_alloc_contig() as it is currently implemented. This is a problem for allocation requests that are not a power of 2 in size, as with 9KB jumbo mbuf clusters.
