- Don't use an atomic operation to update cnt.v_soft in ast(). This is
the only place the variable is written to, and sched_lock is always
held when it is written, so it is already protected and the mutex release
of sched_lock asserts a memory barrier that ensures the value will be
updated in a timely fashion.
warning on Alphas. It is still not the perfect solution for machines
which sizeof(u_long) != sizeof(void *) but it is as close as we are going
to get for now and consistent with the rest of the code. 8.12 has solved
this problem by providing a portable snprintf() which understands %p.

packet flow into two unidirectional flows.
Part of a suite of nodes developed for packet flow control.
More to follow as I have time to port them to 5.x or
as others do so. The ipfw node will be the hardest..

- Remove unneeded spl()'s around mi_switch() in userret().
- Don't hold sched_lock across addupc_task().
- Remove the MD function child_return() now that the MI function
fork_return() is used instead.
- Use TRAPF_USERMODE() instead of dinking with the trapframe directly to
check for ast's in kernel mode.
- Check astpending(curproc) and resched_wanted() in ast() and return if
neither is true.
- Use astoff() rather than setting the non-existent per-cpu variable
astpending to 0 to clear an ast.
- Don't hold sched_lock around addupc_task() as this apparently breaks
profiling badly due to sched_lock being held across copyin().

- Change the switch_trampoline() to call fork_exit() passing in the
required arguments instead of calling the fork trampoline callout
function directly.

Silence a warning by renaming the 'pgtok' #define to 'vmstat_pgtok' so
as not to conflict with the 'pgtok' #define in sys/param.h
* Rip out MACHINE_CPU stuff from sys.mk and include a new <bsd.cpu.mk>
after we pull in /etc/make.conf. We need to do it afterwards so we can
react to the user setting of the:
* CPUTYPE variable, which contains the CPU type which the user wants to
optimize for. For example, if you want your binaries to only run on an
i686-class machine (or higher), set this to i686. If you want to support
running binaries on a variety of CPU generations, set this to the lowest
common denominator. Supported values are listed in make.conf.
* bsd.cpu.mk does the expansion of CPUTYPE into MACHINE_CPU using the
(hopefully) correct unordered list of CPU types which should be used on
that CPU. For example, an AMD k6 CPU wants any of the following:
k6 k5 i586 i486 i386
This is still an unordered list so the client makefile logic is simple -
client makefiles need to test for the various elements of the set in
decreasing order of priority using ${MACHINE_CPU:M<foo>}, as before.
The various MACHINE_CPU lists are believed to be correct, but should be
checked.
* If NO_CPU_CFLAGS is not defined, add relevant gcc compiler optimization
settings by default (e.g. -karch=k6 for CPUTYPE=k6, etc). Release
builders and developers of third-party software need to make sure not to
enable CPU-specific optimization when generating code intended to be
portable. We probably need to move to an /etc/world.conf to allow the
optimization stuff to be applied separately to world/kernel and external
compilations, but it's not any worse a problem than it was before.
* Add coverage for the ia64/itanium MACHINE_ARCH/CPUTYPE.
* Add CPUTYPE support for all of the CPU types supported by FreeBSD and gcc
(only i386, alpha and ia64 first, since those are the minimally-working
ports. Other architecture porters, please feel free to add the relevant
gunk for your platform).
