the devstat is for an "interior" GEOM node and register using the
name argument as a geom identity pointer. Do not put these devstat
structures on the list returned by the sysctl.
This gives us the ability to tell the two kinds of nodes apart and
leave the current "strictly physical" view of devstat intact without
modifications, yet be able to use devstat for both kinds of devices.
It also saves us bloating struct devstat with another 48 bytes of
space for the name. At least for now.

Add a mutex and protect the allocation and traversal of the list with it.
When we allocate a page for devstat use we drop the mutex and use
M_WAITOK this is not nice, but under the given circumstances the
best we can do.
In the sysctl handler for returning the devstat entries we do not want to
hold the mutex across copyout(9) calls, so we keep a very careful eye on
the devstat_generation count, and abandon with EBUSY if it changes under
our feet.
Specifically test for BIO_WRITE, rather than default non-read,non-deletes
as write. Make the default be DEVSTAT_NO_DATA.
Add atomic increments of the sequence[01] fields so applications using the
mmap'ed view stand a chance of detecting updates in progress.

driver should use port or memory based IO, determine it dynamically
at runtime, preferring MMIO where possible. This helps us support newer
arches which dislike port based access better.
Tested on i386 & sparc64, with 3c900, 905, 905b, and 905C cards.

one tx buffer for these cards. The old driver only used one. We use
1 for symbol, and 3 for prism cards.
o Don't do the maximum loops thing in the ISR. In fact, revert to the
old interrupt handler. Lucent cards don't seem to work too well if
you don't disable/enable interrupts from the card in the ISR.
Between these two changes, Lucent cards suck less. They work in
autoselect mode only. And seem to get 1Mbps or 2Mbps only. Setting a
specific media speed doesn't work, and I've had a few issues even with
these patches. They turn a former brick into a nearly useful card.
These patches work on the prism 2 and 2.5 PC Card cards that I have.
I've not tested this on PCI cards. I suspect, but couldn't find
proof, that they were the reason that the ISR was changed so radically
from its FreeBSD roots in NetBSD. We might need to have a variant ISR
if so.
4 bits. This reportedly fixes booting on the SW7500CW2. Much thanks to

I don't recall now, but for some reason I didn't think it was needed.
Also place the mdconfig right before the chroot call, to make it stand out
this needs to be done in the standard environment, as we've tried doing it
in the chroot environment before.
- Use SYSINIT to initialize the structures instead of checking
total_bpages against 0 in alloc_bounce_pages(), which could lead
to several initializations being done at the same time.
- Add missing locking in bus_dmamap_load(), the bounce pages mutex
must be held when calling reserve_bounce_pages() and when touching
the bounce_map_waitinglist list.
- Remove the useless splhigh() and splx() calls.
- Assert that the bounce pages mutex is held in reserve_bounce_pages()
to catch regressions.
code both seem to call wi_start (directly or via the if_start pointer)
without checking to see if OACTIVE is 0. In addition, I think that
with the use of 3 transmit buffers this routine can be called with
OACTIVE set, but I might be mistaken about that (and it doesn't
matter).

but I decided that it was important for this patch to not bit-rot, and
since it is mainly moving code around, the total amount of entropy is
epsilon /phk)
This is a patch to move the common parts of linux_getcwd() back into
kern/vfs_cache.c so that the standard FreeBSD libc getcwd() can use it's
extended functionality. The linux syscall linux_getcwd() in
compat/linux/linux_getcwd.c has been rewritten to use it too. It should
be possible to simplify libc's getcwd() after this. No doubt this code
needs some cleaning up, since I've left in the sysctl variables I used
for debugging.

shared object of libobjc, we end up linking in from the archive
version. This is wrong, because we don't compile the archive version
suitable for inclusion in shared objects. On ia64 this causes actual
breakages. Compile the archive version with PIC on ia64 to avoid
the breakage there and also to avoid changing the status quo on
other architectures. If other architectures have the same problem,
we probably should start building a shared library. There's no
indication however that other architectures actually need it.
Building the archive version with PIC on ia64 does pessimize linking
complete binaries (ie fully archive), but we don't use Objective-C
ourselves and so far I haven't seen non-shared executables written
in Objective-C, so I'm sure this will be nothing but academic.
