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).

Power ISA 2.05 adds support for extended mtfsf/mtfsfi form, with a new

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
the DisasContext struct. Finally change all accesses to the opcode fields
through extract helpers, prefixed with FP for consistency.

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.

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.

pseries: Fixes and enhancements to L1 cache properties
PAPR requires that the device tree's CPU nodes have several properties
with information about the L1 cache. We already create two of these
properties, but with incorrect names - "[id]cache-block-size" instead
of "[id]-cache-block-size" (note the extra hyphen).
We were also missing some of the required cache properties. This
patch adds the [id]-cache-line-size properties (which have the same
values as the block size properties in all current cases). We also
add the [id]-cache-size properties.
Adding the cache sizes requires some extra infrastructure in the
general target-ppc code to (optionally) set the cache sizes for
various CPUs. The CPU family descriptions in translate_init.c can set
these sizes - this patch adds correct information for POWER7, I'm
leaving other CPU types to people who have a physical example to
verify against. In addition, for -cpu host we take the values
advertised by the host (if available) and use those to override the
information based on PVR.

pseries: Fix incorrect calculation of RMA size in certain configurations
For the pseries machine, we need to advertise to the guest the size of its
RMA - that is the amount of memory it can access with the MMU off. For HV
KVM, this is constrained by the hardware limitations on the virtual RMA of
one hash PTE per PTE group in the hash page table. We already had code to
calculate this, but it was assuming the VRMA page size was the same as the
(host) backing page size for guest RAM.
In the case of a host kernel configured for 64k base page size, but running
on hardware (or firmware) which only allows 4k pages, the hose will do all
its allocations with a 64k page size, but still use 4k hardware pages for
actual mappings. Usually that's transparent to things running under the
host, but in the case of the maximum VRMA size it's not.
This patch refines the RMA size calculation to instead use the largest
available hardware page size (as reported by the SMMU_INFO call) which is
less than or equal to the backing page size. This now gives the correct
RMA size in all cases I've tested.

PPC: mac newworld: fix cpu NIP reset value
On -M mac99, we can run 970 CPUs. However, these CPUs define the initial
instruction pointer they start execution at as part of their bootup protocol,
so effectively it's up to the board to decide where they start.
This went unnoticed, because they used to boot at the same location our flash

to 0x100 now, which is always a 0 instruction.
Set the initial IP to something reasonable for -M mac99.
