In directory netbsd1:/var/slash-tmp/cvs-serv15339

Modified Files:
        genassym.c locore.s machdep.c pmap.c 
Log Message:

Changes for NKPDE calculation from cgd.

- New variables: biosextmem, biosbasemem, nkpde
- Above can be set by using the options BIOSEXTMEM, BIOSBASEMEM,
  and NKPDE respectively (EXTMEM_SIZE is now called BIOSEXTMEM).
  When preset this way, they won't be filled in / calculated.
- Readable by sysctl using machdep.nkpde, machdep.biosbasemem
  and machdep.biosextmem.
- nkpde is calculated as:

        min(NKPDE_MAX, NKPDE_BASE + (biosextmem >> 10) * NKPDE_SCALE)

  Where NKPDE_MAX is 31, NKPDE_BASE is 4, NKPDE_SCALE = 1.
