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.
