ec956cbe3a Don't enable interrupts while calling trap() if the trapping frame 
didn't have them enabled either.

Addresses PR port-macppc/29559.

111117ce57 fix two bugs with wiring: 
(1) in pmap_enter_pv(), we would always mark the header entry wired, even if
     the new entry wasn't put there.  noticed by Juergen Hannken-Illjes.
 (2) in pmap_unwire(), we would never examine the header entry.
     noticed by me.

while I'm here, move the counter increment in the pmap_enter() path to be
next to the corresponding PV_WIRE() call so it's more obvious they match.

6451b0332b Update to a kcore_hdr_t that is useful for OEA-style CPUs. Adding 
support for Book-E and other CPUs will require updating this structure
appropriately.

d6e37f352e Keep track of the CPU's current speed (in kHz) in the cpu info structure, 
if we can get it.  May want to expand this in the future to include min
and max speeds for systems where we can adjust the speed.

dc5fd1a390 Use lis@h/ori@l instead of lis@ha/addi@l since we may use r0 and addi 
is one of those funny instructions that treats r0 == 0 when used as the
first arg.

9704ef243d Add consinit() and md_consinit funcptr to ibm4xx/machdep.c. 
Rename consinit() to obs405_consinit() at evbppc/obs405/consinit.c.

Set md_consinit to obs405_consinit() at initppc().
Consinit fuction calls a function stored at md_consinit pointer.
