In addition to returning the first value in $v0, the additional

The syscalls are used instead of the separate syscalls for those values

Implement LSI53C895A quirks exposed by OpenServer (Justin Chevrier).
After going through the debug log and scratching my head for quite some
time. I found the following:
The problem was with this block move:
lsi_scsi: SCRIPTS dsp=
0fae8e50 opcode
01000028 arg
00f63c40
lsi_scsi: DMA addr=0x00f63c40 len=36
The number of bytes to be transferred (len) should be 40 which corresponds
to the block transfer of length 0x28 (from opcode
01000028). Instead we
have a length of 36 (0x24). The code responsible for this is (in
'lsi_do_dma'):
if (count > s->current_dma_len)
count = s->current_dma_len;
Basically we're overwriting the length 40 with the value 36 which I
think we just left over in that variable from an earlier transfer. In my
patch below I initialize s->current_dma_len to s->dbc before we begin
the DMA transfer during Data In phase.
The attached patch gets Openserver 5.0.5 past the hardware detection
(and it lists the hard drive to boot, woohoo). It appears to stop a
little while later (doesn't seem SCSI related), but it's been so long since
I've booted Openserver I'm not sure what's supposted to happen after the HW
detection using the boot/root disks.
Props go to Craig Ringer for the initial post and the code that he posted
some of which is in this patch.

Syntax is the same as for vnc, using a to= option, like this:
-serial tcp:localhost:5000,to=5099,server
This will check the 5000 -> 5099 port range (inclusive) for a free tcp
port. Likewise you can get auto-allocated unix sockets by specifying an
empty path:
-serial unix:,server
qemu will create a randomly named socket in $TMPDIR then.
tcp also got new "ipv4" and "ipv6" options to make qemu try only the

qemu: generate signals on tap I/O
Currently tap does not generate signals on I/O; this causes
network latency to be dependent on the timer tick (1ms without
dyntick, guest dependent with dyntick). By generating a signal
on I/O, we can inform the guest immediately that a packet has
arrived.

Fix interrupt exclusion via SSTEP_NOIRQ
Commit #5620 revealed an issue of the SSTEP_NOIRQ masking that was
applied on all interrupt sources (including internal ones) when single
stepping through the guest. Due to that commit, we now ended up in an
infinite loop when CPU_INTERRUPT_EXIT was pending on SSTEP resume. That
was due to #5620 eating all TBs while CPU_INTERRUPT_EXIT is pending, but
SSTEP_NOIRQ preventing CPU_INTERRUPT_EXIT to be processed.
What SSTEP_NOIRQ should actually do is to block the delivery of all
external, guest visible interrupts. With the fix below applied, single
stepping now works again.

target-alpha: Fix ret instruction
Hopefully pine doesn't corrupt this patch, I've had problems recently.
For an alpha "ret" instruction, of the type
ret $26
The return was being ignored. This is because in translate.c
register $26 (the return address) was being over-written with the current
PC before it could be jumped to. Thus the ret was ignored.
This patch just re-orders things so the return address is processed before
it is over-written with the current PC.

Fix windows build after init_host_timer changes.
host_alarm_timer fires in a separate thread. The windows build current
uses SetEvent() and WaitEvent() to then notify the main thread. This is
functionally equivalent to what we're doing in Unix with pipe(). So let's
just #ifdef the pipe() code on Windows since it doesn't build there anyway.

Fix alarm_timer race with select - v3 (Jan Kiszka)
Changing the default IO timeout to 5 s (#5578) made a race visible
between the alarm_timer and select() in main_loop_wait(): If the timer
fired before select was able to block, the full select() timeout could
have been applied instead of returning immediately. Since #5578, this
causes heavy problems to the Musicpal board emulation with stalls up to
5 s, but also with some older Linux guest kernels.
The following patch introduces a pipe that is written to by
host_alarm_handler and select()'ed in main_loop_wait(). This avoids
prevents that select() blocks though a timer has fired and waits for
processing.
