Peter Wemm 50e2347e68 Kill the 4MB kernel limit dead. [I hope :-)].
For UP, we were using $tmp_stk as a stack from the data section.  If the
kernel text section grew beyond ~3MB, the data section would be pushed
beyond the temporary 4MB P==V mapping.  This would cause the trampoline
up to high memory to fault.  The hack workaround I did was to use all of
the page table pages that we already have while preparing the initial
P==V mapping, instead of just the first one.
For SMP, the AP bootstrap process suffered the same sort of problem and
got the same treatment.

MFC candidate - this breaks on 4.x just the same..
