Opps ...

Ok this can occur when pmap_enter() is called to map in a page for which a
page table does not exist. pmap_enter() will first try and allocate a page
table and map that and then map in the desired page. For this panic to
occurs means that the uvm_pagealloc() call to get a page from the VM to
use as a page table failed.

I need to look at a solution for this. What comes to mind is that I need
to implement pmap_collect() in order to recover some memory and/or give
the pagedaemon a look in as it will have been woken by uvm_pagealloc().
