with more than one read(). When we detect one, don't
forget to pass it to async_Input() and drop our
terminal back into command mode.
Don't output an extraneous \r if we're passed \r\n
to prompt_vprintf in raw mode.
In particular, replace the unused field pmap::pm_flag by pmap::pm_active,
which is a bit mask representing which processors have the pmap activated.
(Thus, it is a simple Boolean on UPs.)
Also, eliminate an unnecessary memory reference from cpu_switch()
in swtch.s.

in time to build inetd. (If you already have /usr/include/tcpd.h, the
build doesn't fail. This mainly affects upgrades and 'make world' from
systems more than a few weeks old)
Add Sound Card ID for the nss(NEC PC-9801-86 Sound System) driver.
Old name of this driver was pcm driver in FreeBSD 2.2.x.
Fix lack of the length of the name member of the synth_info structure.
(attach_mpu401 in sys/i386/isa/sound/mpu401.c requires 33 chars.)
o sys/i386/isa/sound/dev_table.h
Add the DMAbuf flags definition DMA_DISABLE.
Add the nss driver entry.
o sys/i386/isa/sound/dmabuf.c
Add the DMA_DISABLE flag check in DMAbuf_outputintr and DMAbuf_inputintr
to disable DMA control in FIFO only use (nss driver required).
o sys/i386/isa/sound/local.h
Add the nss driver entry.
o sys/i386/isa/sound/mpu401.c
Replace inb function in probe_mpu401 to mpu401_status macro.
Wrap macro argument for above replace.
Add I/O port maping macro for NEC PC-98x1 arch.
Add delay in NEC PC-98x1 arch.
o sys/i386/isa/sound/pcm86.c
Change driver name to avoid name space conflict to new pcm driver.
Fix NEC PC-9801-86 driver to work on RELENG_3 branch or latter.
o sys/i386/isa/sound/sound_calls.h
Fix the mpuintr definition.
Add the nss driver entry.
attach_nss, probe_nss, nssintr
o sys/i386/isa/sound/soundcard.c
Fix lack of the mpuintr registration.
Add the nss driver entry.
o sys/pc98/conf/files.pc98
Add the nss driver entry.

somewhat emetic usage of vinum_slices and the equally obnoxious 'vinum
read' command.
and CPU runtime because it can't access the user area via /proc/<pid>/mem.
This is because the uarea is not mapped into the process address space
at USRSTACK on the alpha like it is on the x86.
Since I'm haven't been able to wrap my brain around the VM system enough
to be able to figure out how to achieve this mapping, and since it's
questionable that such an architectural change is correct, I implemented
a workaround to allow ps(1) to read the uarea from /dev/kmem using
kvm_read() instead of from the process address space via kvm_uread().
The kludge is hidden inside #ifdef __alpha__/#endif so as not to impact
the x86. (Note that top(1) probably uses this same gimmick since it works
on FreeBSD/alpha.)

make /etc/rc interruptible in cases when programs hang with blocked
signals) isn't standard enough.
It is now switched off by default and a new switch -T enables it.
You should update /etc/rc to the version I'm about to commit in a few
minutes to keep it interruptible.
Like the PNIC, we have to copy packet headers in the receive handler
because the chip will only DMA to longword aligned buffers.
Also do some mindor cleanups.
