users, so there's no point in printing these.
Also fix a number of compiler warnings, including two real bugs:
- a bracket placement bug caused `mount -t ufs localhost:/foo /mnt'
to override the `-t ufs' specification and use mount_nfs.
- an unitialised variable was used instead of _PATH_SYSPATH when
warning that the mount_* program cound not be found.

about failing to use MNT_BYFSID) by silencing the second
warning too. Also fix a misspelling in a comment.

reaches 0, one could never restart any more without a reboot.
Steve Passe did the leg work on this patch. After he found the fix,
we discovered that an identical fix had been made to NetBSD.

UTS with the stack correctly aligned. Also, while here, use an indirect
jump rather than the pushq/ret hack.
This fixes threaded apps that use floating point for me, although
it hasn't solved all the problems. It is an improvement though.
Preservation of the 128 byte red zone hasn't been resolved yet.

ABI-required stack alignment. C code expects that the push of the
return address disturbed the 16 byte alignment and it will take corrective
measures to fix it before making another call. Of course, if its wrong
to start with, then all hell breaks loose. Essentially we "fix" this
by making the stack alignment odd to start with.
This was one of the things that broke on libkse with apps that use
floating point/varargs/etc.

- Add a really, really, nasty hack to provide stub versions of all of
the 'device apic' functions used by the ACPI MADT APIC enumerator if
'device apic' is not compiled into the kernel. This is gross but is
the best we can do with the current kernel linker implementation.

SI_SUB_CPU - 1 and probe enumerators, probe CPUs, and setup the local
APIC programming all at SI_SUB_CPU / SI_ORDER_FIRST. This is needed to
help get the ACPI module working again as it moves the APIC enumeration
code after SI_SUB_KLD.
- In the MADT parser, use mp_maxid rather than MAXCPU to terminate a loop
when assigning per-cpu ACPI IDs to avoid a dependency on 'options SMP'.
- Allow the apic device to be disabled via 'hint.apic.0.disabled' from the
loader. Note that since this is done in the local APIC code, it works
for both the ACPI and non-ACPI cases.

- Dynamically allocate the cpu_softc[] array based on mp_maxid instead of
using a statically sized array that depended on 'options SMP'.
- Use mp_maxid rather than MAXCPU when walking all the CPUs looking for a
match.
- Always call smp_rendezvous() since UP kernels now provide this.
- Use mp_ncpus rather than cpu_ndevices when determining if we need to
disable C3 for SMP machines.

the acpi_cpu(4) driver, to work properly with both SMP and UP kernels.
The exported symbols include mp_ncpus, all_cpus, mp_maxid, smp_started, and
the smp_rendezvous() function. This also means that CPU_ABSENT() is now
always implemented the same on all kernels.

This is the vastly updated cx drvier from Roman Kurakin <rik@cronyx.ru>
who has been patiently waiting for this update for sometime.
The driver is mostly a rewrite from the version we have in the tree.
While some similarities remain, losing the little history that the old
driver has is not a big loss, and the re@ felt it was easier this way (less
error prone).
The userland parts of this update will be committed shortly.
The driver is not connected to the build yet. I want to make sure I
don't break any platform at any time, so I want to test that with
these files in the tree before I continue (on the off chance I'm
forgetting a file).
I changed the DEBUG macro to CX_DEBUG from the code that was submitted
(to not break when we go to building with opt_global.h after the
release), as well adding $FreeBSD$.

we can end up with some threads with a non-16-byte-aligned stack. This
causes some interesting side effects, including general protection
faults leading to a SIGBUS when doing floating point or varargs. This
should be just a verbose NOP for the other platforms.

Before committing the initial tcp_hostcache I changed them from memcpy()
to conform with FreeBSD style without realizing the difference in argument

This fixes hostcache operation for IPv6 (in general and explicitly IPv6
