From 9f368ce71c70a77488981071f2622c3cdbd650a5 Mon Sep 17 00:00:00 2001
From: Pedro Martelletto <pedro@cvs.openbsd.org>

Subject: - when we run out of static kernel map entries, grab a fresh page
 using   the uvm_km_page allocator and use it instead of calling panic() - add
 a counter to uvmexp so we can keep track of how many map entries   we have in
 use

idea from tedu@, long ago, okay deraadt@
