1. Process p1 is currently being swapped in.
2. Process p2 calls linux_ptrace(PTRACE_GETFPXREGS, p1_pid, ...)
3. After acquiring a reference to FIRST_THREAD_IN_PROC(p1),
p2 blocks in faultin() while p1 finishes being swapped in.
This means p2 won't get back the lock on p1 until after p1's
threads are runnable.
4. After p1 is swapped in, the first thread in p1 exits.
5. p2 now uses its dangling reference to p1's first thread.

all dependent on the NOPORTREADMES knob as well as the NOPORT knob
(at the moment NOPORT may be set while NOPORTREADMES isn't, that
should probably be revisited). And it hardcodes ia64 for NOPORTREADMES
by request the ia64 release builder.
While here really get rid of the temp file 'make index' leaves behind.
Tested by: i386 and ia64 'make release'

after loading such a kernel, "module_path" will be set to
an insane value. Fixed example by providing an equivalent
setting. For the record, when automatically loading a
kernel (commands "boot" and "boot-conf"), the following is
tried, in this order:
path=/boot/${kernel} file=${bootfile}
path=/boot/${kernel} file=${kernel}
path=${kernel} file=${bootfile}
path=${kernel} file=${kernel}
path=${module_path} file=${kernel}
Document this. These changes make it possible to write something like
set device "!/usr/bin/rfcomm_sppd -a BD_ADDR"
inside the /etc/ppp/ppp.conf file. Very convenient for the users :)

MP machines (hopefully). CPU timers are OK on UP machines but we
don't keep the timers in sync on MP machines so if the CPU's timer
is chosen as the primary timecounter it's possible for time to
not be monotonically increasing because different CPU's counters
may be used at different times. But the CPU's counters are otherwise
one of the higher quality counters available. So, on UP machines
we'll use a relatively high quality value but on MP machines we'll
use a quality that should prevent the CPU's counters from being chosen.

the structure space had been obtained from malloc() its contents is
random garbage. The choice of value being set is part of a larger effort
to solve some timecounter issues on MP machines (while working on that
we noticed this problem).

the new subr_unit.c code.
For now assert Giant in ttycreate() and ttyfree(). It is not obvious that
it will ever pay off to lock these with anything else.
- Document better what the -C option means.
- The -c option is currently a no-op.
- The -D and -h options do not allow switching between
single/dual console modes and internal/video consoles.
(This used to be true for the old biosdisk boot code,
but now they just force the multiple consoles mode and
serial console, respectively.)

2. Add an IPv4 listen-on option for 127.0.0.1, which is appropriate
for the default use as a local resolver.
3. Add a commented out listen-on-v6 option.
Allocation is always lowest free unit number.
A mixed range/bitmap strategy for maximum memory efficiency. In
the typical case where no unit numbers are freed total memory usage
is 56 bytes on i386.
malloc is called M_WAITOK but no locking is provided (yet). A bit of
experience will be necessary to determine the best strategy. Hopefully
a "caller provides locking" strategy can be maintained, but that may
require use of M_NOWAIT allocation and failure handling.
A userland test driver is included.

Correct handling of SADB_UPDATE and SADB_ADD requests. key_align may
split the mbuf due to use of m_pulldown. Discarding the result because
of this does not make sense as no subsequent code depends on the entire
msg being linearized (only the individual pieces). It's likely
something else is wrong here but for now this appears to get things back
to a working state.
