Out of the approximately 1450 man pages, only about 90 of them were wrong.
Thanks to kwesterback@home.com for coming up with a script and patch to repair
this. The patch also inserted a .Os macro in the few man pages that were
missing one.

(Some of these changes are work in progress and may change more later)
locore.S:
rearranged to remove most of the direct openfirmware references in
the attempt to move all of the openfirmware pieces into ofw_ files.
This could allow other firmware type to be supported easier. Also
this keeps the openfirmware code grouped in the same files.
OF_buf is now statically allocated in the data/bss section instead
of allocated during initialization.
machdep.c:
change the order of vm initialization, Still considering removing
the BATs from use. instead of calls directly to ppc_exit and ppc_boot
these are now called via a firmware function pointer structure.
Add iMac recognition to systems
ofw_machdep.c:
function pointer structure to allow different firmware to supply
specific system functionality, normally startup and reset,
including a hook to notify when bsd is about to go virtual,
in case firmware calls need to act different after that time.
Allow BSD to handle the virtual memory operations for openfirmware.
this idea was copied from NetBSD macppc, It is not fully implemented,
among other problems, openfirmware does not have a mechanism to
add new mappings.
ofwreal.S:
Major rewrite of the firmware call code, It still copies
a portion of the stack, but now does not restore exeception vectors.
Modified to be similar in idea to NetBSD macppc with BSD handling
the openfirmware VM faults/TLB misses.
This still needs to be reviewed, Should be possible to not require
any stack copy.
opendev.c:
OF_bus is not a pointer to the buffer, but is the buffer itself now.
openfirm.c:
OF_bus is not a pointer to the buffer, but is the buffer itself now.
Dont panic if OF_boot fails, OF_boot can be called by panic.
instead print and the hang in a spin loop.
pmap.c:
call the firmware function to get memory regions.
Scale the PowerPC hash table size by size of real memory.
Properly align the hash table based on the start, not just
the size.

It is a debugging operation anyway.

start using the ddb_regs. If the address is specififed, start from the
address.
|
|
saved for debugging purposes.

protocols.
"struct tcpiphdr" is now gone from much of the code, as are separate pointers
for ti and ti6. The result is fewer variables, which is generally a good thing.
Simple if(is_ipv6) ... else ... tests are gone in favor of a
switch(protocol family), which allows future new protocols to be added easily.
This also makes it possible for someone so inclined to re-implement TUBA (TCP
over CLNP?) and do it right instead of the kluged way it was done in 4.4.
The TCP header template is now referenced through a mbuf rather than done
through a data pointer and dtom()ed as needed. This is partly because dtom() is
evil and partly because max_linkhdr + IPv6 + TCP + MSS/TS/SACK opts won't fit
inside a packet header mbuf, so we need to grab a cluster for that (which the
code now does, if needed).
