Direct mapping for framebuffer is required only if fb(4) is console.

XXX
It would be nice if we can remove reserved TLB entries after
fb(4) is properly attached.

Identify oneself as ``Explora 450'' instead of 451.

There are models numbered 450 to 454. The differences b/w them are
shapes of ethernet and audio connectors. Base model number 450 is

Proposed on tech-kern@.

It is not appropriate to call pmf_system_shutdown(9) from
doshutdownhooks(9): shutdown hooks registered by shutdownhook_establish(9)
expect to be called with interrupts disabled, but shutdown hooks
registered with pmf_device_register1(9) expect to be called with
interrupts enabled. So I have made two changes:

1 Do not call pmf_system_shutdown() from doshutdownhooks(). Instead,
change every call to doshutdownhooks() to a call to doshutdownhooks()
followed by a call to pmf_system_shutdown(). No functional change
is intended by this change.

2 Make i386 re-enable interrupts briefly while it calls
pmf_system_shutdown(). I leave it to others either to fix the
other ports, or to factor out some MI shutdown code, as joerg@
suggests, and fix that. Note that a functional change *is* intended
by this change.

I hope that this patch will stop us from flip-flopping between
calling doshutdownhooks() and pmf_system_shutdown() sometimes with
and sometimes without interrupts enabled.

too many TLB entries, see

http://mail-index.netbsd.org/port-powerpc/2006/10/27/0000.html

is considered "programming error" by 405 core and results in "undefined
behaviour". We now avoid mapping peripherals in kernel segment.

Mapping of console device goes into the reserved tlb's.
Max. memory is 32M for console at fb and 48M for console on com.

If this becomes a problem TLB_NRESERVED needs to become variable.

Replace the traditional buffer memory management -- based on fixed per buffer
virtual memory reservation and a private pool of memory pages -- by a scheme
based on memory pools.

This allows better utilization of memory because buffers can now be allocated
with a granularity finer than the system's native page size (useful for
filesystems with e.g. 1k or 2k fragment sizes). It also avoids fragmentation
of virtual to physical memory mappings (due to the former fixed virtual
address reservation) resulting in better utilization of MMU resources on some
platforms. Finally, the scheme is more flexible by allowing run-time decisions
on the amount of memory to be used for buffers.

On the other hand, the effectiveness of the LRU queue for buffer recycling
may be somewhat reduced compared to the traditional method since, due to the
nature of the pool based memory allocation, the actual least recently used
buffer may release its memory to a pool different from the one needed by a
newly allocated buffer. However, this effect will kick in only if the
system is under memory pressure.

Split the softc from the device_t for all lpt(4) variants and attachments
except the ppbus stuff (which doesn't compile) and ulpt(4) which is
unrelated and can be dealt with separately.

As usual, it comes with related cosmetic changes.

Avoid doubly bus_space_map(9) when pckbc(4) is already attached as console.

pckbcintr() must be running with IPL_TTY, not IPL_SERIAL. Otherwise,
tty(4) routines are unexpectedly interrupted, which results in
"locking against myself" errors for tty_lock.

Convert to intr_establish_xname().

Stop registering same function twice, i.e., for pckbd(4) and pms(4),
via intr_establish().
