 Log Message:
 The recent kmem changes allocate a large kernel address space before
 pmap_init() is called, and the initial kernel PT pages aren't enough
 for the allocations pmap_init().  This fails because pmap_kenter_pa()
 tries to allocate a new kernel PT page and traps because the pmap has
 not been initialized.  When computing the number if initial kernel PT
 pages, include enough to allow kmem to map the physical memory.  This
 should fix PR/45915.  OK by releng@.  One mac68k system has been verified
 to boot.  Volunteers to test the others welcome.  Amigas with at least
 up to 128MB of memory were OK, but larger memory will need some adjusting.
