Pavel Dovgalyuk 355d4d1c00 m68k: fix subx mem, mem instruction
This patch fixes decrement of the pointers for subx mem, mem instructions.
Without the patch pointers are decremented by OS_* constant value instead of
retrieving the corresponding data size and using it as a decrement.

Thomas Huth 052888f043 hw/s390x: Allow to configure the consoles with the "-serial" parameter
The consoles ("sclpconsole" and "sclplmconsole") can only be configured
with "-device" and "-chardev" so far. Other machines use the convenience
option "-serial" to configure the default consoles, even for virtual
consoles like spapr-vty on the pseries machine. So let's support this
option on s390x, too. This way we can easily enable the serial console
here again with "-nodefaults", for example:

qemu-system-s390x -no-shutdown -nographic -nodefaults -serial mon:stdio

... which is way shorter than typing:

qemu-system-s390x -no-shutdown -nographic -nodefaults \
  -chardev stdio,id=c1,mux=on -device sclpconsole,chardev=c1 \
  -mon chardev=c1

The -serial parameter can also be used if you only want to see the QEMU
monitor on stdio without using -nodefaults, but not the console output.
That's something that is pretty impossible with the current code today:

qemu-system-s390x -no-shutdown -nographic -serial none

While we're at it, this patch also maps the second -serial option to the
"sclplmconsole", so that there is now an easy way to configure this second
console on s390x, too, for example:

qemu-system-s390x -no-shutdown -nographic -serial null -serial mon:stdio

Additionally, the new code is also smaller than the old one and we have
less s390x-specific code in vl.c :-)

I've also checked that migration still works as expected by migrating
a guest with console output back and forth between a qemu-system-s390x
that has this patch and an instance without this patch.

David Hildenbrand e7c3246162 s390x/kvm: cleanup calls to cpu_synchronize_state()
We have a call to cpu_synchronize_state() on every kvm_arch_handle_exit().

Let's remove the ones that are no longer needed.

Remaining places (for s390x) are in
- target/s390x/sigp.c, on the target CPU
- target/s390x/cpu.c:s390_cpu_get_crash_info()

While at it, use kvm_cpu_synchronize_state() instead of
cpu_synchronize_state() in KVM code. (suggested by Thomas Huth)

Greg Kurz c96f2c2a16 vfio-ccw: introduce vfio_ccw_get_device()
A recent patch fixed leaks of the dynamically allocated vcdev->vdev.name
field in vfio_ccw_realize(), but we now have three freeing sites for it.
This is unfortunate and seems to indicate something is wrong with its
life cycle.

The root issue is that vcdev->vdev.name is set before vfio_get_device()
is called, which theoretically prevents to call vfio_put_device() to
do the freeing. Well actually, we could call it anyway  because
vfio_put_base_device() is a nop if the device isn't attached, but this
would be confusing.

This patch hence moves all the logic of attaching the device, including
the "already attached" check, to a separate vfio_ccw_get_device() function,
counterpart of vfio_put_device(). While here, vfio_put_device() is renamed
to vfio_ccw_put_device() for consistency.

Peter Maydell 2b3f64cbf3 linux-user: Fix getdents emulation for 64 bit guest on 32 bit host
Currently we mishandle emulation of the getdents syscall for the
case of a 64 bit guest on a 32 bit host -- it defaults into
the 'host and guest same size' codepath and generates incorrect
structures in the guest buffer.

We can't easily handle the 64-on-32 case using the host getdents
syscall, because the guest struct dirent is bigger than the
host struct dirent, and we might find the host syscall has handed
us back more records than we can fit in the guest buffer after
conversion. Instead, always emulate 64-on-32 getdents with
the host getdents64. This avoids the buffer-overrun problem
because a dirent64 struct is always the same size on any host
and always larger than any architecture's dirent struct.

Alex Bennée b02ebad1dc linux-user: set minimum uname for RISC-V
As support for RISC-V was only merged into the mainline kernel at 4.15
it is unlikely that glibc will be happy with a reported kernel version
of 3.8.0. Indeed when I testing binaries created by the current Debian
Sid compiler the tests failed with:

  FATAL: kernel too old

Bump the version to the minimum a RISC-V glibc would expect:
