>Description:
Now even enabling MULTIPROCESSOR I get:
cpu1 at cpunode0 core 1 disabled (unresponsive)

Reverting these two commits makes it run the second CPU (and promptly fall flat on its face):

Maintain the split of physical memory into the defined freelists, but
only force pool pages to VM_FREELIST_FIRST512M for non _LP64

Always use XKPHYS for pool pages on _LP64; otherwise use KSEG0

 Never mind 'more broken than before'.

 With LOCKDEBUG and DEBUG I can boot to userland and run pretty heavy
 programs.
