  Modified files:
    sys/amd64/amd64      pmap.c 
    sys/i386/i386        pmap.c 
    sys/vm               uma_int.h 
  Log:
   - Significantly reduce the number of preallocated pv entries in
     pmap_init().  Such a large preallocation is unnecessary and wastes
     nearly eight megabytes of kernel virtual address space per gigabyte
     of managed physical memory.
   - Increase UMA_BOOT_PAGES by two.  This enables the removal of
     pmap_pv_allocf().  (Note: this function was only used during
     initialization, specifically, after pmap_init() but before
     pmap_init2().  During pmap_init2(), a new allocator is installed.)
