9827f27b9f Update from thorpej: 
* Define type and size of _mcount stub to make PIC code happy.
* Rename mcount to __mcount to get it out of the user namespace.

9451559ef4 pmap_page_protect(VM_PROT_NONE) must remove all mappings in the PV list, 
even if they are wired.  we need to be able to remove all mappings to
pages that are being freed due to (eg.) file truncation.

25e9f1f519 Provide basic bus_space_mmap(). Noted by self and in PR port-powerpc/14873. 
This at least allows the compile to complete.  There are still Issues with
vga_pci.c's assumptions about a PC-ish environment.

b45c51b1fc Roll the rest of the ports over to the new MI kernel build machinery. 
Any problems reported by testers have been fixed, and massive
cross-compiling of kernels has shown that any problems that remain
with actually building kernels are not related to this.

163114ab3c Implement pmap_kenter_pa() and pmap_kremove() properly. 
This should fix `kernel diagnostic assertion "rv" failed' panic
and the problem was tracked down by tsubai.
Also add small optimization in pmap_enter() and pmap_remove(), from tsubai.

ecb81c3f6d - convert usage of "defopt" to "defflag" where the relevant option does 
not support a value (e.g., it's to be used as "options FOO" instead of
  "options FOO=xxx"). options that take a value were converted to
  defparam recently.
- minor whitespace & formatting cleanups

34d4887431 Some #ifdef cleanup for DIAGNOSTIC/DEBUG/PMAPCHECK so that that many of 
the expensive checks are skipped when (!DEBUG&&!PMAPCHECK) and all of the
light-weigth checks are skipped when (!DIAGNOSTIC&&!DEBUG&&!PMAPCHECK).
This bring pmap.o's text down from 21KB (with PMAPCHECK) to 18.5KB (DEBUG)
to 16KB text (!DIAGNOSTIC).

ab93af26ea Fix pte_clear to TLB flush the va, not the tlb adress (which is only valid

15a42388c0 In pmap_enter(), sync the instruction cache if VM_PROT_EXECUTE. Fixes 
problems when executing programs where text is copied to a page without
a dma sync (like NFS data bcopy'd to a buffer cache page).
