- Don't try to ring bell and immediately return from do_bell() while
device probe is in progress at boot time; the timeout queue is not
functional yet.

- A new option: SC_DISABLE_REBOOT
The reboot key (usually Ctl-Alt-Del) will be ignored if this option
is defined. You may still have the reboot key defined in the keymap and
it won't cause error when the keymap is loaded, but it will be quietly
treated as nop.

userconfig script.
This provides an escape mechanism whereby a broken userconfig script may
be worked around.

I've worked to enhance the connect() patches.
I've just tested this with the Linux JDK appletviewer on an applet
that does a lot of connects, and it works as well as during my
previous tests.
The connect() patch is now a merge between my older patch and the
OpenBSD stuff. It ensures that any async error is returned by
connect() instead of getsockopt(SOL_SOCKET, SO_ERROR) as reasonnable
systems do.
There are also minor patches to implement IPPROTO_TCP for
get/setsocktopt(). These are also tested (with Linux Apache).

I would appreciate any feedback regarding these changes, as they'd
be very useful in 2.2.6.

of the various ad-hoc schemes.
2) When bringing in UPAGES, the pmap code needs to do another vm_page_lookup.
3) When appropriate, set the PG_A or PG_M bits a-priori to both avoid some
processor errata, and to minimize redundant processor updating of page
tables.
4) Modify pmap_protect so that it can only remove permissions (as it
originally supported.) The additional capability is not needed.
5) Streamline read-only to read-write page mappings.
6) For pmap_copy_page, don't enable write mapping for source page.
7) Correct and clean-up pmap_incore.
8) Cluster initial kern_exec pagin.
9) Removal of some minor lint from kern_malloc.
10) Correct some ioopt code.
11) Remove some dead code from the MI swapout routine.
12) Correct vm_object_deallocate (to remove backing_object ref.)
13) Fix dead object handling, that had problems under heavy memory load.
14) Add minor vm_page_lookup improvements.
15) Some pages are not in objects, and make sure that the vm_page.c can
properly support such pages.
16) Add some more page deficit handling.
17) Some minor code readability improvements.
so that it is possible for kdump and truss to include them both. Use
#defines from pcvt_ioctl.h in conflicting cases, since pcvt_ioctl.h
gives a hint about the bogus third arg to _IO(). Ifdef the common
typedefs. Export `struct key_t' from pcvt_ioctl.h so pcvt_ioctl.h is
bug for bug compatible with console.h (now both are broken in C++
mode).

code to support bktr_read . /usr/src/share/examples/rgb24.c now works 8)
2. Flemming Jacobsen <fj@schizo.dk.tfs.com> submitted code to support
radio available with in some bt848 based cards;additionally, wrote
code to correctly recognized his bt848 card.
3. Roger Hardiman <roger@cs.strath.ac.uk> submitted various fixes to smooth
out the microcode and made all modes consistent.
4. Added supported for yuv12 so we know can capture raw streams and feed it
to mpeg_encoder . The upshot is that we can now mpeg encode more and save
nearly 100 percent of the disk requirements previously for programs such
as fxtv first save the raw video image to disk then converted to a
format suitable for mpeg_encode.
prematurely when there was a hole (for a cdrom or an unused
interface) in the sequence of wd drives. This caused non-free
wd units to be probed as atapi drives. There was no problem
provided the atapi probe failed correctly.
MUST be PG_BUSY. It is bogus to free a page that isn't busy,
because it is in a state of being "unavailable" when being
freed. The additional advantage is that the page_remove code
has a better cross-check that the page should be busy and
unavailable for other use. There were some minor problems
with the collapse code, and this plugs those subtile "holes."
Also, the vfs_bio code wasn't checking correctly for PG_BUSY
pages. I am going to develop a more consistant scheme for
grabbing pages, busy or otherwise. For now, we are stuck
with the current morass.
