Alan Cox 72aebdd742 Recent changes have created, for the first time, physical memory segments
that can be coalesced.  To be clear, fragmentation of phys_avail[] is not
the cause.  This fragmentation of vm_phys_segs[] arises from the "special"
calls to vm_phys_add_seg(), in other words, not those that derive directly
from phys_avail[], but those that we create for the initial kernel page
table pages and now for the kernel and modules loaded at boot time.  Since
we sometimes iterate over the physical memory segments, coalescing these
segments at initialization time is a worthwhile change.
