By accident, a previously unused bit in the PTE got used as wired bit.
...
Because of this kvtophys() of wired pages did set the leftmost bit, causing
the pager to hang while swapping. This is now fixed by using another
free bit in the PTE as wired bit instead.
This fixes PR#11121.
Many thanks to Chuck Silvers that found what the problem was!

GCC 2.96 wants the = constraint first. Older gcc(s) don't care.

Write kvtopte() and kvtophys() as inline assembler. GCC create quite bad
...
code for them, and they are only 2-3 instructions each if written by hand.

Rewrite the "emulate page reference bits" code to avoid a bunch of

Giant change: NBPG now set to 4k and CLSIZE == 1 for vax. This change
...
made a whole bunch of annoying bugs disappear; mostly depending on
bad use of NBPG in non-MD code. The VAX port was the only port that
used this historical "feature".
The CL* macros should probably go away totally, there is no reason
at all to keep them.
