Make vm_object_prefer() call MD aligner for "pageless" objects too,
so we can have more control over the virtual address to be used.
Implementation could be simpler if we by-pass the object to mapped, but
we'd loose the ability to adapt alignment to objects that were previously
mmap'ed with MAP_FIXED on.
allocated, as noticed by Chuck Cranor. In addition to re-arranging
the assignment as suggested by Niklas Hallqvist, check to see if maxproc
is higher than the number of available user PTs. If it is, lower maxproc
to that value, the rationale being that it's much more desirable to have
fork() return EAGAIN than to have your system wedge.
XXX note that root can still raise maxproc with sysctl(2) later. It's
probably worth having further discussion about this issue, but until
everyone has time to think about it, this seems like an acceptable solution
for the time being.
again, and it turned NetBSD in ostype[] to N^CtBSD... Thanks Charles (again)
Also call epstop() in the attach routine to make sure that the pci card
gets reset properly.
This is a step towards getting the drivers ready for new config.
Clean up namespace, remove several instances of global arrays. Instead,
use a softc to carry state around. Where possible, pass a pointer to
the softc rather than a unit number.
Pointers to hardware and software constructs are now stored per port
in each instance of the softc (one softc per board) rather than indexed
by minor number.

of FIFO overflows on high baud rates.
However, doing so on all 4 ports would cost a whopping 64KB (at 4096 entries
per FIFO) of kernel memory. So, the FIFOs are now allocated at attach time
allowing the size for the keyboard and mouse ports to be reduced (to 128)
which should be adequate for the 1200 baud they use.
