A more robust fallback path is also provided, with the last recourse

These changes drastically simplify the machine-dependant parts of

More to follow...
if_fe.c uses PCCARD_MODULE() and is part of GENERIC. I've #ifdef'ed out
the #include of "card.h" to hopefully disable pccard support in this
driver until it can be converted. I'm not positive this will fix make
release, but it can't possibly make it any worse than it is now.
I hope this stuff settles down soon.
o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored. This may change the units
assigned to a card. It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot. we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
allow it to attach. See config files that were committed for examples
on how to do this.
Drivers to be commited shortly.
This is an interrum fix until the new pccard. ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.
I plan on doing minimal further work on this code base. Be careful
when upgrading, since this code is known to work on my laptop and
those of a couple others as well, but your milage may vary.
BUGS TO BE FIXED:
o system memory isn't allocated yet, it will be soon.
o No devices actually have a pccard newbus attach in the tree.
BUGS THAT MIGHT BE FIXED:
o card removal, including suspend, usually hangs the system.

Reorganize the attachement point for pcic (it was unattached and
floating before). Attach pccard devices to pcic, one per slot
(although this may change to one per pcic). pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet). Move pccard compat code
into pccard/pccard_compat.c.
THIS REQUIRES A CONFIG FILE CHANGE. You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller pcic0 at isa?
controller pcic1 at isa?
controller card0
The old system was upside down and this corrects that problem. It
will make it easier to add support for YENTA pccard/card bus bridges.
Much more cleanup needs to happen before newbus devices can have
pccard attachments. My previous commit's comments were premature.

glibc2 defines struct dirent differently than the Linux kernel does.
The getdents function therefore needs to read a heuristically defined
number of kernel dirents to satisfy the request. In case where too
many kernel dirents have been read, the function lseeks on the
directory so that a next call will start with the right dirent. The
offset used in lseeking is the offset-field in the last dirent passed
to the application. This can only mean that the offset-field holds
the offset of the next dirent and not the offset of the dirent itself.

I feel less dirty now.
In order to make this work, I created a pseudo-PHY driver to deal with
Macronix chips that use the built-in NWAY support and symbol mode port.
This is actually all of them, with the exception of the original MX98713
which presents its NWAY support via the MII serial interface.
The mxphy driver actually manipulates the controller registers directly
rather than using the miibus_readreg()/miibus_writereg() bus interface
since there are no MII registers to read. The mx driver itself pretends
that the NWAY interface is a PHY locayed at MII address 31 for the sole
purpose of allowing the mxphy_probe() routine to know when it needs to
attach to a host controller.

* Turn the pnpbios code into an enumerator for the isa bus. This allows
all devices known to the bios to be probed automatically.
Currently the pnpbios code is dependant on the PNPBIOS option. As the code

default. I have PnP changes in the wings for fdc, atkbd, psm, pcaudio, and
joy. Sio already works with pnpbios.

It confuses the remote debugger as the definition of 'struct device' in
device.h is found before the one in bus_private.h.
struct sigcontext and ucontext_t/mcontext_t are defined in such
a way that both (ie struct sigcontext and ucontext_t) can be
passed on to sigreturn. The signal handler is still given a
ucontext_t for maximum flexibility.
For backward compatibility sigreturn restores the state for the
alternate signal stack from sigcontext.sc_onstack and not from
ucontext_t.uc_stack. A good way to determine which value the
application has set and thus which value to use, is still open
for discussion.
NOTE: This change should only affect those binaries that use
sigcontext and/or ucontext_t. In the source tree itself
this is only doscmd. Recompilation is required for those
applications.
This commit also fixes a lot of style bugs without hopefully
adding new ones.
