Multiqueue patchset conditionally add control vq only when guest negotiate the
feature. Though the spec is not clear on this but it breaks the minix guest
since it will identify the ctrl vq even if it does not support it. Though this
behavior seems a violation on the spec "If the VIRTIO_NET_F_CTRL_VQ feature bit
is negotiated, identify the control virtqueue.", to keep the backward
compatibility, always add the ctrl vq at end of the queues.

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.

uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe,

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.

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
was mapped to, but due to the recent reset changes our 970 CPUs want to reset
to 0x100 now, which is always a 0 instruction.
Set the initial IP to something reasonable for -M mac99.

This value is not needed if we use correctly the MSR[IP] bit.
excp_prefix is always 0x00000000, except when the MSR[IP] bit is
implemented and set to 1, in that case excp_prefix is 0xfff00000.
The handling of MSR[IP] was already implemented but not used at reset
because the value of env->msr was changed "manually".
The patch uses the function hreg_store_msr() to set env->msr, this
ensures a good handling of MSR[IP] at reset, and therefore a good value
for excp_prefix.

Use of a flash memory device for the BIOS was added in series "[PATCH
v10 0/8] PC system flash support", commit 4732dca..1b89faf, v1.1.
Flash vs. ROM is a guest-visible difference. Thus, flash use had to
be suppressed for machine types pc-1.0 and older. This was
accomplished by adding a dummy device "pc-sysfw" with property
"rom_only":
* Non-zero rom_only means "use ROM". Default for pc-1.0 and older.
* Zero rom_only means "maybe use flash". Default for newer machines.
Not only is the dummy device ugly, it was also retroactively added to
the older machine types! Fortunately, it's not guest-visible (thus no
immediate guest ABI breakage), and has no vmstate (thus no immediate
migration breakage). Breakage occurs only if the user unwisely
enables flash by setting rom_only to zero. Patch review FAIL #1.
Why "maybe use flash"? Flash didn't (and still doesn't) work with
KVM. Therefore, rom_only=0 really means "use flash, except when KVM
is enabled, use ROM". This is a Bad Idea, because it makes enabling/
disabling KVM guest-visible. Patch review FAIL #2.
Aside: it also precludes migrating between KVM on and off, but that's
not possible for other reasons anyway.
Fix as follows:
1. Change the meaning of rom_only=0 to mean "use flash, no ifs, buts,
or maybes" for pc-i440fx-1.5 and pc-q35-1.5. Don't change anything
for older machines (to remain bug-compatible).
2. Change the default value from 0 to 1 for these machines.
Necessary, because 0 doesn't work with KVM. Once it does, we can flip
the default back to 0.
3. Don't revert the retroactive addition of device "pc-sysfw" to older
machine types. Seems not worth the trouble.
4. Add a TODO comment asking for device "pc-sysfw" to be dropped once
flash works with KVM.
Net effect is that you get a BIOS ROM again even when KVM is disabled,
just like for machines predating the introduction of flash.
To get flash instead, use "--global pc-sysfw.rom_only=0".

With pipelining it is possible to encounter a finished packet when cleaning
the queue due to a halt. This happens when a non stall error happens while
talking to a real device. In this case the queue on the usb-host side will
continue processing packets, and we can have completed packets waiting in
the queue after an error condition packet causing a halt.
There are 2 reasons to discard the completed packets at this point, rather
then trying to writing them back to the guest:
1) The guest expect to be able to cancel and/or change packets after the
packet with the error without doing an unlink, so writing them back may
confuse the guest.
2) Since the queue does not advance when halted, the writing back of these
packets will fail anyways since p->qtdaddr != q->qtdaddr, so the
ehci_verify_qtd call in ehci_writeback_async_complete_packet will fail.
Note that 2) means that then only functional change this patch introduces
is the printing of a warning when this scenario happens.
Note that discarding these packets means that the guest driver and the device
will get out of sync! This is unfortunate, but should not be a problem since
with a non stall error (iow an io-error) the 2 are out of sync already anyways.
Still this patch adds a warning to signal this happening.
Note that sofar this has only been seen with a DVB-T receiver, which gives
of a MPEG-2 stream, which allows for recovering from lost packets, see:

Drop all the infrastructure for taddr properties (ie ones which
are 'hwaddr' sized). These are now unused, and any further desired
use would be rather questionable since device properties shouldn't
generally depend on a type that is conceptually variable based on
the target CPU. 32 or 64 bit integer properties should be used instead
as appropriate for the specific device.

- Add vhost_scsi_get_features() in order to determine feature bits
supports by host kernel (mst + nab)
- Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow
EVENT_IDX to be disabled by host in vhost_scsi_get_features()
- Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES

Because dev->actual is uint32_t, the expression 'dev->actual <<
VIRTIO_BALLOON_PFN_SHIFT' is truncated to 32 bits. This overflows when
dev->actual >= 1048576.
To reproduce:
1. Start a VM with a QMP socket and 5G of RAM
2. Connect to the QMP socket, negotiate capabilities and issue:
{ "execute":"balloon", "arguments": { "value": 1073741824 } }
3. Watch for BALLOON_CHANGE QMP events, the last one will incorretly be:
{ "timestamp": { "seconds": 1366228965, "microseconds": 245466 },
"event": "BALLOON_CHANGE", "data": { "actual": 5368709120 } }
To fix it this commit casts it to ram_addr_t, which is ram_size's type.

Drop the vpb_pci_config_addr() function -- it is unnecessary since

The versatile_pci PCI controller has a set of control registers which
handle the mapping between PCI and system address spaces. Implement
these registers (though for now they have no effect since we don't
implement mapping PCI space into system memory at all).
The most natural order for our sysbus regions has the control
registers at the start, so move all the others down one.

Implement the correct IRQ mapping for the Versatile PCI controller; it
differs between realview and versatile boards, but the previous QEMU
implementation was correct only for the first PCI card on a versatile
board, since we weren't swizzling IRQs based on the slot number.
Since this change would otherwise break any uses of PCI on Linux kernels
which have an equivalent bug (since they have effectively only been
tested against QEMU, not real hardware), we implement a mechanism
for automatically detecting those broken kernels and switching back
to the old mapping. This works by looking at the values the kernel
writes to the PCI_INTERRUPT_LINE register in the config space, which
is effectively the interrupt number the kernel expects the device
to be using.

Comments in the QEMU source code claim that the version of the PCI
controller on the VersatilePB board doesn't support the PCI I/O
region, but this is incorrect; expose that region, map it in the
correct location, and drop the misleading comments.
This change removes the only currently implemented difference
between the realview-pci and versatile-pci models; however there
are other differences in not-yet-implemented functionality, so we
retain the distinction between the two device types.
