virtio-net: count VIRTIO_NET_F_MAC when calculating config_len
Commit
14f9b664 (hw/virtio-net.c: set config size using host features) tries to
calculate config size based on the host features. But it forgets the
VIRTIO_NET_F_MAC were always set for qemu later. This will lead a zero config
len for virtio-net device when both VIRTIO_NET_F_STATUS and VIRTIO_NET_F_MQ were
disabled form command line. Then qemu will crash when user tries to read the
config of virtio-net.
Fix this by counting VIRTIO_NET_F_MAC and make sure the config at least contains
the mac address.

Wire up disabled wait a panicked event on s390
On s390 the disabled wait state indicates a state of attention.
For example Linux uses that state after a panic. Lets
put the system into panicked state.
An alternative implementation would be to state
disabled-wait <address> instead of pause in the action field.
(e.g. z/OS, z/VM and other classic OSes use the address of the
disabled wait to indicate an error code).

Multiqueue patchset conditionally add control vq only when guest negotiate the

win32: add readv/writev emulation
Commit
e9d8fbf (qemu-file: do not use stdio for qemu_fdopen, 2013-03-27)
introduced a usage of writev, which mingw32 does not have. Even though
qemu_fdopen itself is not used on mingw32, the future-proof solution is
to add an implementation of it. This is simple and similar to how we
emulate sendmsg/recvmsg in util/iov.c.
Some files include osdep.h without qemu-common.h, so move the definition
of iovec to osdep.h too, and include osdep.h from qemu-common.h
unconditionally (protection against including files when NEED_CPU_H is
defined is not needed since the removal of AREG0).

For that the helper is changed to handle 64-bit input values and mask with
up to 16 bits. The mtfsf/mtfsfi instructions do not have the W bit
marked as invalid anymore. Instead this is checked in the helper, which
therefore needs to access to the insns/insns_flags2. They are added in

target-ppc: optimize fabs, fnabs, fneg
fabs, fnabs and fneg are just flipping the bit sign of an FP register,
this can be implemented in TCG instead of using softfloat.

PPC: Fix dcbz for linux-user on 970
The default with linux-user for dcbz on 970 is to emulate 32 byte clears.
However, redoing the dcbzl support we added a check to not honor the bit
in HID5 that sets this.
Remove the #ifdef check on linux user, so that we get 32 byte clears again.

pseries: Generate device paths for VIO devices
This patch implements a get_dev_path qdev hook for the pseries paravirtual
VIO bus. With upcoming savevm support, this will become very important for
scsi disks hanging of VIO virtual SCSI adapters. scsibus_get_dev_path
uses the get_dev_path of the parent adapter if available, but otherwise
just uses a local channel/target/lun number to identify the device. So if
two disks are present in the system having the same target and lun on
seperate VIO scsi adapters, savevm cannot distinguish them. Since the
conventional way of using VSCSI adapters is to have just one disk per
adapter, such a conflict is very likely.

pseries: Convert VIO code to QOM style type safe(ish) casts
Curerntly the pseries VIO device code contains quite a few explicit
uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe,
and not the conventional way of doing things in the QOM model. This
patch converts the code to use the QOM convention of per-type macros
to do verified casts with OBJECT_CHECK().

target-ppc: Synchronize VPA state with KVM
For PAPR guests, KVM tracks the various areas registered with the
H_REGISTER_VPA hypercall. For full emulation, of course, these are tracked
within qemu. At present these values are not synchronized. This is a
problem for reset (qemu's reset of the VPA address is not pushed to KVM)
and will also be a problem for savevm / migration.
The kernel now supports accessing the VPA state via the ONE_REG interface,
this patch adds code to qemu to use that interface to keep the qemu and
KVM ideas of the VPA state synchronized.
