46c8f7f1c2 Convert the ThunderLAN driver to miibus. This took me a while because I
had to get the ML 6692 PHY driver working correctly, which is harder than
it sounds. "Bitrate" ThunderLAN devices should still be supported (i.e
the older 10Mbps Netflex 3/P, which use the TNETE110 chip that has no
MII support). The ThunderLAN has an internal PHY which makes things a
little complicated, but these are the basic rules:

- For devices with just the ThunderLAN, the internal PHY is used to
  provide 10baseT, and 10base5/10baseT support. Autonegotiation will
  work, but only with 10baseT links. The only thing that really gets
  negotiated is whether the link is full or half duplex.

- For devices with the ThunderLAN and an external 10/100 PHY (like the
  Compaq Netelligent 100Mbps cards, or the internal Netflex 3/P with
  100Mbps upgrade daughter card), the external PHY is used for 10baseT
  and 100baseTX modes. The internal PHY is still used to support
  10base5/10base2, though you have to select them manual with ifconfig.

- For devices with the ThunderLAN and the ML6692 PHY, both the internal
  and external PHYs are used, though it will appear as though the 6692
  PHY will be used to support 10baseT and 100baseTX modes. In reality,
  the internal PHY will be used for 10baseT, but this fact will be hidden
  from the user. The 10base5/10base2 modes can also be selected manually
  as with above.

d341237291 Add miibus drivers for the ThunderLAN internal PHY and the Micro Linear
ML6692 PHY. The Micro Linear driver is my own; the ThunderLAN driver is
a port of the NetBSD driver with various hacks. The ML driver is necessary
to support the Olicom OC-2326 ThunderLAN-based NIC.

Also regenerated miidevs.h to pick up the proper 'obtained from'
revision string.

34067f9475 Fix the child's return path from fork so that fork will return 0
in the child.  This corrects a problem where linux/alpha binaries see
the child's return value of fork as the parent's pid.  This happens because
linux/alpha binaries apparently check the return value directly, rather
than looking for a non-zero value in a4, as *BSD & OSF/1 do.

dbafb3660f Simplify the handling of VCHR and VBLK vnodes using the new dev_t:
Make the alias list a SLIST.

        Drop the "fast recycling" optimization of vnodes (including
        the returning of a prexisting but stale vnode from checkalias).
        It doesn't buy us anything now that we don't hardlimit
        vnodes anymore.

        Rename checkalias2() and checkalias() to addalias() and
        addaliasu() - which takes dev_t and udev_t arg respectively.

        Make the revoke syscalls use vcount() instead of VALIASED.

        Remove VALIASED flag, we don't need it now and it is faster
        to traverse the much shorter lists than to maintain the
        flag.

        vfs_mountedon() can check the dev_t directly, all the vnodes
        point to the same one.

Print the devicename in specfs/vprint().

Remove a couple of stale LFS vnode flags.

Remove unimplemented/unused LK_DRAINED;

4a54450a9d It would help if things that MUST be 32 bit aligned were really 32 bit
aligned.  If I recall correctly, this is to ensure apic_imen can be

c85f67175f Fix {g|s}etgroups semantics. We use cr_groups[0] to hold egid. This means that
egid will be twice in the set and that setting cr_groups[0] will change egid.
This is simply solved by ignoring cr_groups[0]. That is; linux_getgroups does
not return cr_groups[0] and linux_setgroups does not touch it.

0ff7b13acd Make DEVFS use PHK's specinfo struct as the source of dev_t and devsw.
In lookup() however it's the other way around as we need to supply the
dev_t for the vnode, so devfs still has a copy of it stashed away.

Sourcing it from the vnode in the vnops however is useful as it makes
a lot of the code almost the same as that in specfs.

devsw(a_vp->v_rdev), and it's own copy of the dev_t.

076dab2983 When the SYSINIT() was removed, it was replaced with a make_dev on-demand
creation of /dev/drum via calling swapon. However, the make_dev has a
bogus (insofar that it hasn't been added yet) cdevsw, so later we end
up crashing with a null pointer dereference on the swap vp's specinfo.
The specinfo points to a dev_t with a major of 254 (uninitialized), and
we get a crash on its d_strategy being called.

The simple solution to this is to call cdevsw_add before the make_dev
is ever used. This fixes the panic which occurred upon swapping.
