newbus in revision 1.19. As a result, lnc was, I believe, broken
for all PCI cards. The softc fields `lnc_btag' and `lnc_bhandle'
were not initialised, `rap', `rdp' and `bdp' were initialised to
the wrong values, and the size of the DMA ring memory was calculated
incorrectly.
Paul Richards has further cleanups in the pipeline, but this at
least is enough to make the driver usable with VMware.

An initial tidyup of the mount() syscall and VFS mount code.
This code replaces the earlier work done by jlemon in an attempt to
make linux_mount() work.
* the guts of the mount work has been moved into vfs_mount().
* move `type', `path' and `flags' from being userland variables into being
kernel variables in vfs_mount(). `data' remains a pointer into
userspace.
* Attempt to verify the `type' and `path' strings passed to vfs_mount()
aren't too long.
* rework mount() and linux_mount() to take the userland parameters
(besides data, as mentioned) and pass kernel variables to vfs_mount().
(linux_mount() already did this, I've just tidied it up a little more.)
* remove the copyin*() stuff for `path'. `data' still requires copyin*()
since its a pointer into userland.
* set `mount->mnt_statf_mntonname' in vfs_mount() rather than in each
filesystem. This variable is generally initialised with `path', and
each filesystem can override it if they want to.
* NOTE: f_mntonname is intiailised with "/" in the case of a root mount.
of memory, rather than from the start.
This fixes problems allocating bouncebuffers on alphas where there is only
1 chunk of memory (unlike PCs where there is generally at least one small
chunk and a large chunk). Having 1 chunk had been fatal, because these
structures take over 13MB on a machine with 1GB of ram. This doesn't leave
much room for other structures and bounce buffers if they're at the front.

actual presence of a configured ethernet card, and/or ppp/tun devices.
Of course, it's easy to disable in rc.conf.
If the -tag list definition didn't have a -width modifier,
the first .It call was supposed to set the width depending
on the first argument type; if it is a macro name, use the
macro's width value; otherwise, use width value of `No'.
The following two lists should produce identical output:
.Bl -tag -width Er -compact
.It Er EINVAL
invalid argument
.El
.Bl -tag -compact
.It Er EINVAL
invalid argument
.El
If the outermost -tag list definition did't have a -width
modifier, the .It elements of inner lists might not work
(producing a list where each successive element `walks' to
the right).
Example:
.Bl -tag -compact
.It outer
.It outer
.Bl -tag -compact
.It inner
.It inner
.El
.It outer

the mutex/lock used to serialize its allocation.
for selecting unit). Instead, use the resource hints mechanism.
One unfortunate situation here is that there is no resource_quad_value
function- which is what I needed for WWN boot time replacement. Worse-
you can't store the hint as just plain
hint.isp.0.nodewwn="0x50000000aaaa0001"
because this gets interpreted as an int- incorrectly because it can't
be converted to an int. I can't even get this as a string. To work
around this particular case for nodewwn && portwwn setting, this
rather grotesque form will be used:
hint.isp.0.nodewwn="w50000000aaaa0001"
hint.isp.0.portwwn="w50000000aaaa0002"
At the same time, if we have no hinted WWN, set the default WWN (which, btw,
gets overridden if the card has valid NVRAM, which is usual) to
0x400000007F000009ull (which translates to NAA == IPv4, 127.0.0.9).

Eliminate isp_unit references- we no longer have an isp_unit- we now

`rootvnode' pointer, but vfs_syscalls.c's checkdirs() assumed that
it did. This bug reliably caused a panic at reboot time if any
filesystem had been mounted directly over /.
The checkdirs() function is called at mount time to find any process
fd_cdir or fd_rdir pointers referencing the covered mountpoint
vnode. It transfers these to point at the root of the new filesystem.
However, this process was not reversed at unmount time, so processes
with a cwd/root at a mount point would unexpectedly lose their
cwd/root following a mount-unmount cycle at that mountpoint.
This change should fix both of the above issues. Start_init() now
holds an extra vnode reference corresponding to `rootvnode', and
dounmount() releases this reference when the root filesystem is
unmounted just before reboot. Dounmount() now undoes the actions
taken by checkdirs() at mount time; any process cdir/rdir pointers
that reference the root vnode of the unmounted filesystem are
transferred to the now-uncovered vnode.
