96f2e892a7 Add the if_dc driver and remove all of the al, ax, dm, pn and mx drivers
which it replaces. The new driver supports all of the chips supported
by the ones it replaces, as well as many DEC/Intel 21143 10/100 cards.

This also completes my quest to convert things to miibus and add
Alpha support.

fe0d408987 Remove the 'ivars' arguement to device_add_child() and
device_add_child_ordered().  'ivars' may now be set using the
device_set_ivars() function.

This makes it easier for us to change how arbitrary data structures are
associated with a device_t.  Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.

Despite my best efforts I've probably forgotten something so let me know
if this breaks anything.  I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

8a9d4d98b1 Moved scheduling-related code to kern_synch.c so that it is easier to fix
and extend.  The new function containing the code is named schedclock()
as in NetBSD, but it has slightly different semantics (it already handles
incrementation of p->p_cpticks, and it should handle any calling frequency).

71e4fff823 Retire MFS_ROOT and MFS_ROOT_SIZE options from the MFS implementation.
Add MD_ROOT and MD_ROOT_SIZE options to the md driver.

Make the md driver handle MFS_ROOT and MFS_ROOT_SIZE options for compatibility.

Add md driver to GENERIC, PCCARD and LINT.

This is a cleanup which removes the need for some of the worse hacks in
MFS:  We really want to have a rootvnode but MFS on a preloaded image
doesn't really have one.  md is a true device, so it is less trouble.

This has been tested with make release, and if people remember to add
the "md" pseudo-device to their kernels, PicoBSD should be just fine
as well.  If people have no other use for MFS, it can be removed from
the kernel.

9a46ff715e Fix a confusion between osigcontext and ucontext_t in the previous commit.
Since an osigcontext is smaller, if you check for a valid (much larger sized)
ucontext_t and it fails, we bogusly would reject the osigcontext as per
rev 1.378.  Instead, check for osigcontext range validity first, and
ucontext_t later.  This unbreaks Netscape.

cd906fe3de Optimize two cases in the MP locking code. First, it is not necessary
to use a locked cmpexg when unlocking a lock that we already hold, since
    nobody else can touch the lock while we hold it.  Second, it is not
    necessary to use a locked cmpexg when locking a lock that we already
    hold, for the same reason.  These changes will allow MP locks to be used
    recursively without impacting performance.

    Modify two procedures that are called only by assembly and are already
    NOPROF entries to pass a critical argument in %edx instead of on the
    stack, removing a significant amount of code from the critical path
    as a consequence.

dfe41fc832 Fix clobbers so that GENERIC may compile with GCC 2.95.2.
Historically, the documentation of extended asm was lacking, namely you
should NOT specify the same register as an input, and a clobber.
If the register is clobbered, it should be specified as an output as well,
e.g., by linking input and output through the "number" notation.
(Beware of lvalues, some local variables needed...)

URL:http://egcs.cygnus.com/faq.html

In versions up to egcs-1.1.1, the compiler did not even warn about it,
but it was liable to output bad code. Newer egcs are pickier and simply
refuse to swallow such code.

Note, since *addr changes, it needs to be an output operand.
We might be excessive in saying that all memory has changed.

ed9f9797bb This is a complete rewrite of vfs_conf.c, which changes the way the root
filesystem is discovered.  Preference is given to using the kernel
environment variable vfs.root.mountfrom, which is set by the loader
according to the contents of /etc/fstab.  Changes in the MD code
provide fallback mechanisms for systems not using the loader.

A more robust fallback path is also provided, with the last recourse
being to prompt on the console for a root device.

These changes drastically simplify the machine-dependant parts of
the root configuration process.  In addition, support for CDROM root
devices has been removed; it was a nasty hack and didn't work.

4f76d87b21 Massive rewrite of pccard to convert it to newbus.
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.

Many thanks to Peter Wemm and Doug Rabson for helping me to fill in
the missing bits of New Bus understanding at FreeBSD Con '99.
