7effaaaa7c Disable interrupts when dealing with pvo lists. clean up some things. 
Keep track of executable ness of pages.  Of sync icache executable pages.

dde0daca06 Use __asm __volatile. Use _POWERPC_SPR_H_ 
Add PTE_RO/PTE_RW for old pmap.

363019a6c1 Add a db_active variable that indicates if a call to the debugger is 
active.  Seems to be required by the MI com driver nowadays.

59abdecf4b Add a linux specific trapsignal() function. This is just a passthrough 
on all platforms but the i386. On the i386 we look at T_PROTFLT and send
a SIGSEGV instead of SIGBUS. This makes allegro lisp 5.0 and pvs (a proof
verification system) to work.

XXX[1]: We need to go through each architecture and verify that we send
        the correct signal on each trap type.
XXX[2]: trap.c on all other architectures but i386 needs to be modified
        to s/trapsignal/(*p->p_emul->e_trapsignal)/g

e55c9f74af Add missing braces in pmap_pte_to_pvo (DEBUG|PMAPCHECK defined). Rearrange 
some code so that consistency check in pmap_pte_to_pvo do not trigger on
false positives.  Correct/enhance some printfs.

c7c7dab8f1 Stop overloading unused bits in the pte. Use the low 12bits of the vaddr 
instead to store them.  Add a macro to fetch the vaddr without them.
Make all variables/routines prefixed with pmap_
Cleanup & fix some of the vsid bitmap usage.
Cleanup DEBUG printfs.  Add some more checks to pmap_pvo_to_pte.

0278444e19 Add a check to pvo_check which makes sure the pte is really in the 
pteg_table.   In pte_to_va, take into account if the PTE_HID is set.

18b2f7e6a1 Add a port to IBM's PPC405GP Reference Board (the "walnut") 
by Eduardo Horvath and Simon Burge of Wasabi Systems.

IBM 4xx series CPU features:
 - New pmap and revised trap handler.
 - Support on-chip timers, PCI controller, UARTs
 - Framework for on-chip ethernet and watchdog timer.
General PowerPC features:
 - Add in-kernel PPC floating point emulation
 - New in{,4}_cksum that is between 1.5 and 5 times faster than the
   old version depending on CPU type.
General changes:
 - Kernel support for generic dbsym-style symbols.
