details:   https://anonhg.NetBSD.org/src/rev/80ba660f831a
branches:  trunk
changeset: 536038:80ba660f831a
user:      erh <erh%NetBSD.org@localhost>

description:
Adjust the check for what segments should go on the low priority free list.
If a segment starts exactly at 16M don't try to split it because that causes
the code to try to call uvm_page_physload with a zero length segment.
