4dc1413915 Add sbuf_clear() and sbuf_overflowed(). 
Move the helper macros from sbuf.h to sbuf.c
Use ints instead of size_ts.
Relax the requirements for sbuf_finish(): it is now possible to finish an
overflowed buffer.
Make sbuf_len() return -1 instead of 0 if the sbuf overflowed.

28c039e747 The API UP1100 is close enough to a UP1000 that FreeBSD just works on it, so 
document that fact.

Thanks to Peter Petrakis <ppetrakis@alphalinux.org> for doing a test boot.

cf0be84ff5 Turn on DEVFS by default for the alpha. Aside from vinum as mentioned by 
phk it should work fine.  If you need vinum, then don't add this to your
kernel config until vinum catches up to DEVFS.

b0254d109c Turn DEVFS on by default. 
You may need to turn this off if you you vinum.  Apart from that I know of
no reason not to run with DEVFS.

0fee3d3550 p->p_intr_nesting_level is MI now and initialized to 0 in kern_fork.c, 
so it should be save to KASSERT() on it even on an arch that may not
use it.

bc234bdcac Bah, as my luck would have it, I had a kernel source tree in the window 
while strlcpy() existed, before it got backed out due to an extended
bikeshed argument.  Sigh.  Back to the old version with the redundant
code to terminate the string. :-(

97e32dadb4 The osfulator needs sysvipc to work. Thanks to DES's commit to 
the i386 linulator for pointing this out.

The alpha linulator doesn't need a dependancy, as it already
depends on the osfulator.

21bd1ed3bf - Don't pass in MTX_NORECURSE, as that is only used with spin mutexes and 
is going away soon anyways.  Instead, don't pass MTX_RECURSE to mtx_init,
  so that WITNESS will panic if the driver mutex is recursed on.
- Use MTX_DEF in mtx_init() instead of assuming that it will be 0.

c264e80fb7 Consider that the chipset may be in ECP mode (from BIOS settings) 
even if mode PS/2 is forced with bootflags. As a matter of fact,
chipsets needs some extra configuration for accessing PS/2 mode
from ECP. The current patch is only relevant for generic chipsets
since specific code is supposed to deal with this during detection.
