This eliminates a lot of #ifdef SMP type code. Things like _curproc reside
in a data page that is unique on each cpu, eliminating the expensive macros
like: #define curproc (SMPcurproc[cpunumber()])
There are some unresolved bootstrap and address space sharing issues at
present, but Steve is waiting on this for other work. There is still some
strictly temporary code present that isn't exactly pretty.
This is part of a larger change that has run into some bumps, this part is
standalone so it should be safe. The temporary code goes away when the
full idle cpu support is finished.

The kernel with USERCONFIG_BOOT and VISUAL_USERCONFIG option presents
the user the kernel configuration menu upon boot.
The user can navigate the menu with cursor keys. I think it would be
nice if the user can navigate and select a menu item with regular keys
as well, so that the user who is using a serial console which is not
so capable of esc sequences still can choose a menu item.
With the following patch we can select an item by typing an item
number, 1, 2, or 3, or mnemonic `s' to skip UserConfig, 'v' to enter
the visual mode, and `c' to start the CLI mode. `p', `u', `n', and `d'
will move cursor up and down.

monochrome adapter.
This is rather strange assumption. If there is no dispaly adapter, the
console driver cannot be any good...
In this patch, scinit() is split into two parts; the first part is
now called scvidprobe() which will detect the presence of video card
at the CGA or MONO buffer address and returns TRUE if found. It is
called during sccnprobe() and scprobe(). Both will fail if no video
card is found.
The second part, whose name stays the same as before, scinit(), is
called from sccninit() and scattach() to complete initialization of
the found video card.
The keyboard probe code is moved from scprobe() to sckbdprobe();
scprobe() now calls scvidprobe() and sckbdprobe() to carry out device
probe. (This is rather a cosmetic change, but it sure makes the code
look better organized.)
The problem pointed out by Joerg.
changes relative to the 2.2 compatable version are include file
related, the new multicast interface (!) and the new PCI interface.
This should work "as-is" but has not been tested (I have not been able
to get a dc21x4x based card for testing).
Add a system command to script mechanism (so you can call things like
tzsetup from scripts).
Add noError variable for causing script errors to be ignored.
flag wasn't being respected during vref(), et. al. Note that this
isn't the eventual fix for the locking problem. Fine grained SMP
in the VM and VFS code will require (lots) more work.
out to be a problem with VJ header compression.
davidg spotted this in usr.sbin/ppp/slcompress.c
a while ago, but I believe gave the wrong reasons -
it's too easy to reproduce ! The only scenario that
I've been able to reproduce the problem under is when
m_len is *exactly* 40 ! So go figure !

since it is impossible to distinguish unpromoted types from small
(struct) types. Renamed __va_promote() to __va_size() since it is
related to sizes of args on the stack and not to promotion.

The logic in get_myaddress() is broken: it always returns the loopback
address due to the following rule:
if ((ifreq.ifr_flags & IFF_UP) &&
ifr->ifr_addr.sa_family == AF_INET &&
(loopback == 1 && (ifreq.ifr_flags & IFF_LOOPBACK))) {
The idea is that we want to select the interface address only if it's
up and it's in the AF_INET family. If it turns uout we don't have
such an interface available, we make a second pass through the loop,
this time settling for the loopback interface. But the logic inadvertently
locks out all cases when loopback == 0, so nothing is ever selected until
the second pass (when loopback == 1).
This is changed to:
if (((ifreq.ifr_flags & IFF_UP) &&
ifr->ifr_addr.sa_family == AF_INET) ||
(loopback == 1 && (ifreq.ifr_flags & IFF_LOOPBACK))) {
which I think does the right thing.
This is yet another bogon I discovered during NIS+ testing; I need
get_myaddress() to work correctly so that the callback code in the
client library will work.
