o Only complain about detached children that aren't pccard/cardbus.
o Don't NULL out the pccarddev and cbdev devices. detach just
disassociates the device and driver. It doesn't delete the child.
o on driver added, just probe_and_attach the children. If there's
any children attached, wakeup the device add/delete thread.
o wakeup the add/delete thread with the correct cv_signal() rather
than the bogus wakeup(sc). It used to be that we did a tsleep on
sc in this thread, but switched to the more reliable cv stuff a while
ago w/o changing this.
o Remove bogus checks when reallocating memory for the registers. They
weren't needed and turned out to be completely bogus.
This lets me load/unload pccard with a pccard in a slot and have the
child correctly detach/attach. This should help people that have wi
in their kernel, but that kldload cbb and pccard, for example.
properly (likely due to mbuf exhaustion.) Previously, the driver
got somewhat wedged.
Also, remove the annoying messages printed every time xl_encap
couldn't allocate a mbuf; they served no useful purpose, and just made
an mbuf exhaustion situation more annoying.

- Increaes MAX_BPAGES to 512. Less than this causes fxp to quickly runs out
of bounce pages.
- Add an argument to reserve_bounce_pages indicating wether this operation
should fail or be queued for later processing if we run out of memory.
The EINPROGRESS return value is not handled properly by consumers of
bus_dmamap_load_mbuf.
- If bounce buffers are required allocate minimum 1 bounce page at map
creation time. If maxsize was small previously this could get truncated
to 0 and the drivers would quickly run out of bounce pages.
- Fix a bug handling the return value of alloc_bounce_pages at map creation
time. It returns the number of pages allocated, not 0 on success.
- Use bus_addr_t for physical addresses to avoid truncation.
- Assert that the map is non-null and not the no bounce map in
add_bounce_pages.

the top of the address space to be reclaimed. The problem is that with
the APTD gone the mapable kernel address space runs right to the end of
the 32 bit address space. As a max this is 0x100000000, which can't be
represented in 32 bits, so we have to use ptd entry n-1 and pte offset
n-1, instead of ptd entry n and pte offset 0. There's still 1 page we
can't use, but we gain just under 4 megs of kva (8 megs with PAE).

we're using an atomic operation to clear the suspend flag
in fxp_start(). Since other architectures may need the
same thing, we want to do it all the time and not only
in the __alpha__ case. However, we don't want to use
atomic operations on 16-bit integers, because those may
not be available on any architecture. We're thus faking
a 32-bit atomic operation here. This patch also deals
with endianness here.
