This is a simple patch to change the type of old_env from jmp_buf
to sigjmp_buf. old_env is used by sigsetjmp and as such should be
a sigjmp_buf.
This fixes a stack_chk fail in a OSX 32bit build. Since at least on
OSX sigjmp_buf is four bytes larger then a jmpbuf, resulting in an
overflow in sigsetjmp. Due to variable reordering this overwrites
the stack cookie.

When creating a timer handle, we give the timer id a special magic offset
of 0xcafe0000. However, we never mask that offset out of the timer id before
we start using it to dereference our timer array. So we always end up aborting
timer operations because the timer id is out of bounds.
This was not an issue before my patch e52a99f756 ("linux-user: Simplify
timerid checks on g_posix_timers range") because before we would blindly mask
anything above the first 16 bits.
This patch simplifies the code around timer id creation by introducing a proper
target_timer_id typedef that is s32, just like Linux has it. It also changes the
magic offset to a value that makes all timer ids be positive.

For Linux upstream kernel (e.g. 3.17-rc7), the related compatible string
'xlnx,xps-ethernetlite-2.00.a' is supported, but 'b' is not supported,
so change qemu dtb file to match kernel driver.
The related operation for qemu (after this patch):
yum install libvirt
yum install tunctl
tunctl -b
ip link set tap0 up
brctl addif virbr0 tap0
./configure
make
./microblaze-softmmu/qemu-system-microblaze -M petalogix-s3adsp1800 \
-kernel ../linux-stable.microblaze/arch/microblaze/boot/linux.bin \
-no-reboot -append "console=ttyUL0,115200 doreboot" -nographic \

-net tap,vlan=0,ifname=tap0,script=no,downscript=no
in microblaze qemu bash (guest machine):
ifconfig eth0 add 192.168.122.2 netmask 255.255.255.0
ifconfig eth0 up
Then can telnet 192.168.122.2 directly without password from the host
machine.
The related operation for generating new dtb:
building Linux kernel firstly, then get dts tool "./scripts/dts/dts".
"./scripts/dtc/dtc -I dtb -O dts -o ../work.dts ../qemu/petalogix-s3adsp1800.dtb"

Option 'disable spoolss' is available since Samba 2.0.4, commit

Next, "socket address" was reported as deprecated, use a combination of

Entry opcode needs to check if moving to new register frame would cause

overflows because preceding windowed call* opcode writes return address
to the target register window frame, causing overflow exceptions at the
point of call. But when a sequence of entry opcodes is used for register
window spilling there may not be a call or other opcode that would cause
window check between entries and they would not raise overflow exception
themselves resulting in data corruption.

The block layer read and write functions do not like requests which are
bigger than INT_MAX bytes. Since the VDI bmap is read and written in a
single operation, its size is therefore limited accordingly. This
reduces the maximum VDI image size supported by QEMU to half of what it
currently is (down to approximately 512 TB).
The VDI test 084 has to be adapted accordingly. Actually, one could
clearly see that it was broken from the "Could not open
'TEST_DIR/t.IMGFMT': Invalid argument" line for an image which was
supposed to work just fine.

Old BIOSes left some padding by mistake after the req_size/resp_size.
New QEMU does not like it, thinking it is a bidirectional command.
As a workaround, we can check if the ANY_LAYOUT bit is set; if not, we
always consider the first buffer as the virtio-scsi request/response,
because, back when QEMU did not support ANY_LAYOUT, it expected the
payload to start at the second element of the iovec.
This can show up during migration.

Correct the way PC is updated when single-stepping instructions, by
keeping the old PC only for the BS_EXCP (exception condition) state.
Some MTC0 (and possibly other) instructions switch to the BS_STOP state
to terminate the current translation block, so that the state transition
of the simulated CPU resulting from the CP0 operation takes effect with
the following instruction. This happens with `mtc0 <reg>,c0_config' for
example, typically used to set KSEG0 cacheability.
While single-stepping this has a side-effect of not advancing the PC
past the instruction just executed; subsequent single-step traps will
stop at the same instruction repeatedly. Example:
(gdb) stepi

Make microMIPS FP branches respect CP0.Status.CU1 and trap with a
Coprocessor Unusable exception if COP1 has been disabled; also trap if
no FPU is present at all.
Standard MIPS FP instruction encodings have a more regular structure and
branches are covered with a single umbrella along other instructions.
This is not the case with the microMIPS encoding, this case has to be
taken care of explicitly here. Code to do so has been copied from the
standard MIPS code handler for OPC_CP1, in `decode_opc'.
Problems arising from this bug will generally only show up on user
context switches in operating systems making use of lazy FP context
switches, such as Linux. It will also more readily trigger if software
FPU emulation is used, either implicitly on a non-float CPU, or forced
on a hard-float CPU such as with the "nofpu" Linux kernel command line
argument.
The problem may have been easily missed because we have no hard-float
microMIPS CPU configuration present; in fact we have no microMIPS CPU
configuration of any kind present.

tests/vhost-user-test.c:234: warning: passing argument 1 of 'g_mutex_unlock' from incompatible pointer type
That's because glib-compat.h redefine the g_mutex_lock/unlock
function. Those functions' arguments is CompatGMutex/CompatGCond,
but vhost-user-test.c is using GMutex/GCond, which cause the type
is not consistent.
We can rerealize those functions of vhost-user-test.c,
which need a lots of patches. Let's simply address it, and
leave this file alone.

The SAM instructions simply change 2 bits in PSW.MASK to advertise
the current memory mode. While we can't fully guarantee that 31 bit
mode (or even remotely 24 bit mode) actually work correctly, we don't
check whether lpswe modifies these bits, so we shouldn't keep the
guest from executing SAM instructions either.
This patch implements all SAM instrutions with their actual PSW changing
semantics, making more recent Linux kernels boot properly which do issue
a SAM31 call during early boot.

When injecting an sclp console interrupt into the guest, we increase
the PC by 4 for some reason. I have no idea why I put that code there,
but it's clearly wrong. Remove the increment.
This patch fixes sclp serial input for the ccw machine.

Now that we finally check for presence of dangling sysbus devices, make check
started complaining that the sPAPR PHB is one such device.
However, it really isn't. The spapr PHB is not really a traditional sysbus
device, but much more a special spapr pv device which is already able to get
created dynamically.
Move spapr to its own dynamic sysbus check handling and allow PHB devices to
get allocated dynamically.

Specifically, fix the case where the operands are unordered -- since
the result is non-zero, the CR[6] field should be set to zero.
