Otherwise sysbeep() makes an annoying clicking sound on some systems.
'kbdcontrol -b off' just sets the duration and pitch to zero, it doesn't
set the QUIET_BELL flag.

MFC after: 1 week
fifo_open() waiting for another reader or writer if one arrived and
departed while we were waiting (or a little earlier).
Rev.1.79 broke blocking opens of fifos by making them time out after 1
second. This was bad for at least apsfilter.

doesn't do it. This fixes all known causes of "Context switches not
allowed in the debugger" in mi_switch(). The main cause was trap_fatal()
calling kdb_trap() with interrupts enabled. Switching to ithreads for
interrupt handling then made fatal traps more fatal and harder to debug.
The problem was limited in -current because most interrupt handlers are
blocked by Giant, but it occurred almost deterministically for me because
my clock interrupt handlers are non-fast and not blocked by Giant.
- Clear PCIM_CMD_MWRICEN:
some chips seem to have problem with write invalidate.
clearing this bit fixes SBP timeout problem.

- Set PCIM_CMD_SERRESPEN and PCIM_CMD_PERRESPEN
- Moderate value for latency timer.
which are no longer required now that we have UFS2 with extended

Put what I think are the correct TX RATE translation tables
in place for LUCENT firmware. This is based on the 4.x driver.
Maybe it should be table driven?
ifconfig wi0 media DS/11Mbps still fails, but it fails before
we even get to the txrate stuff, so other things are wrong.

Default ic_fixed_rate to -1. This is the same thing as autoselect.
There really should be a #define for this...
- Use it in atacontrol(8) when listing ATA devices instead of
stopping at the first ENXIO received.
This makes atacontrol list work on my sparc64 where the two ATA
channels I have are numbered 2 and 3.

changing the first argument to be a register_t ** to match the prototype

- Move UltraSPARC I and II (spitfire, blackbird, sapphire, sabre) specific

functions that will need to move here.
- Add an ipi handler for data cache flushing on UltraSPARC III.
- Use function pointers to select the right cache flushing functions based
on cpu_impl.
With this it is possible to boot single user from an mfs root on UltraSPARC

no support for the host to pci bridge, and no documentation for it is
publically available.

- Disable the "system tick" interrupt for UltraSPARC III. This avoids
an interrupt storm on startup since we're not prepared for these at
all. This feature has questionable use anyway.
- Clear tick on startup and then leave it alone.
