a wierd double-queue arrangement.. It always empties the if_snd queue
then puts the transmit packets into a different queue that is limited
by the number of TX descriptors and does it's own discards...
This should stop the boot-time XXX warning anyway.

after the volume had been fully operational; involves a change in the
use of the VF_NEWBORN flag. Now if you add a plex to a volume which
is up, the plex will be down and the subdisks stale. You need to
explicitly start the subdisks, which copies data from the good
subdisks to the uninitialized ones.

give_sd_to_drive:
correct method to give the entire largest chunk of drive to the
subdisk. Now it's enough to specify a length, and vinum will give
you as much as it can. Not to be recommended except for empty
drives.
Correct a bogon which made vinum refuse to give the last sector of
a drive to a subdisk.

Change %q formats to %ll before the former go away. This doesn't make
much difference, since kernel kvprintf currently doesn't support
either, and the messages in question are just error messages.

shared library when invoking global constructors and destructors.
For constructors, the object files used to be processed from first
to last; now they're done from last to first. (Destructors are done
in the opposite order, as required by the C++ standard.) This makes
us consistent with standard gcc and egcs compilers. It also
eliminates ordering differences between dynamic and static
executables.
Bump the value of __FreeBSD_version to 400002 to reflect this
change.
This can have bad security implications, but the impact on FreeBSD
systems is minimal because this fs isn't in the default kernels and it
is unknown if it even works.

in the not APIC_IO case. This should silence the warnings when
building pcic.c as well as the undefined functions when the kernel
links.
Noticed by: several people in -current and me building the kernel
space. When doing this, it is possible to for another process to attempt
to get an exclusive lock on the vnode and deadlock the mmap/read
combination when the uiomove() call tries to obtain a second
shared lock on the vnode. There is still a potential deadlock
situation with write()/mmap().

This change implements a relatively sophisticated fix to getnewbuf().
There were two problems with getnewbuf(). First, the writerecursion
can lead to a system stack overflow when you have NFS and/or VN
devices in the system. Second, the free/dirty buffer accounting was
completely broken. Not only did the nfs routines blow it trying to
manually account for the buffer state, but the accounting that was
done did not work well with the purpose of their existance: figuring
out when getnewbuf() needs to sleep.
The meat of the change is to kern/vfs_bio.c. The remaining diffs are
all minor except for NFS, which includes both the fixes for bp
interaction AND fixes for a 'biodone(): buffer already done' lockup.
Sys/buf.h also contains a chaining structure which is not used by
this patchset but is used by other patches that are coming soon.
This patch deliniated by tags PRE_MAT_GETBUF and POST_MAT_GETBUF.

with >=2GB of RAM. Booting on machines with exactly 4GB requires other

- Removed the note that the VESA option cannot be used on the SMP system;
this is not true.
- Moved the option VESA to more appropriate place.
- Refined internal interface in keyboard drivers so that:
1. the side effect of device probe is kept minimal,
2. polling mode function is added,
3. and new ioctl and configuration options are added (see below).
- Added new ioctl: KDSETREPEAT
Set keyboard typematic rate. There has existed an ioctl command,
KDSETRAD, for the same purpose. However, KDSETRAD is dependent on
the AT keyboard. KDSETREPEAT provides more generic interface.
KDSETRAD will still be supported in the atkbd driver.
- Added new configuration options:
ATKBD_DFLT_KEYMAP
Specify a keymap to be used as the default, built-in keymap.
(There has been undocumented options, DKKEYMAP, UKKEYMAP, GRKEYMAP,
SWKEYMAP, RUKEYMAP, ESKEYMAP, and ISKEYMAP to set the default keymap.
These options are now gone for good. The new option is more general.)
KBD_DISABLE_KEYMAP_LOADING
Don't allow the user to change the keymap.
Move the Olicom token ring driver to the officially sanctionned location of
/sys/contrib. Also fix some brokenness in the generic token ring support.
Be warned that if_dl.h has been changed and SOME programs might
like recompilation.
