Add context-cache to cache context-entry encountered on a page-walk. Each
VTDAddressSpace has a member of VTDContextCacheEntry which represents an entry
in the context-cache. Since devices with different bus_num and devfn have their
respective VTDAddressSpace, this will be a good way to reference the cached
entries.
Each VTDContextCacheEntry will have a context_cache_gen and the cached entry
is valid only when context_cache_gen equals IntelIOMMUState.context_cache_gen.

"iommu" as a switch
Add Intel IOMMU emulation to q35 chipset and expose it to the guest.
1. Add a machine option. Users can use "-machine iommu=on|off" in the command
line to enable/disable Intel IOMMU. The default is off.
2. Accroding to the machine option, q35 will initialize the Intel IOMMU and
use pci_setup_iommu() to setup q35_host_dma_iommu() as the IOMMU function for
the pci bus.
3. q35_host_dma_iommu() will return different address space according to the
bus_num and devfn of the device.

Replace "init/destroy" with "realize/unrealize" in SCSIDeviceClass,
which has errp as a parameter. So all the implementations now use
error_setg instead of error_report for reporting error.
Also in scsi_bus_legacy_handle_cmdline, report the error when
initializing the if=scsi devices, before returning it, because in the
callee, error_report is changed to error_setg. And the callers don't
have the right locations (e.g. "-drive if=scsi").

This introduces an NMI (Non Maskable Interrupt) interface with
a single nmi_monitor_handler() method. A machine or a device can
implement it. This searches for an QOM object with this interface
and if it is implemented, calls it. The callback implements an action
required to cause debug crash dump on in-kernel debugger invocation.
The callback returns Error**.
This adds a nmi_monitor_handle() helper which walks through
all objects to find the interface. The interface method is called
for all found instances.
This adds support for it in qmp_inject_nmi(). Since no architecture
supports it at the moment, there is no change in behaviour.
This changes inject-nmi command description for HMP and QMP.

To ensure two virtserialports don't get added to the system with the
same 'name' parameter, we need to access all the ports on all the
devices added, and compare the names.
We currently don't have a list of all VirtIOSerial devices added to the
system. This commit adds a simple linked list in which devices are put
when they're initialized, and removed when they go away.

kernel directly. It's working when xen uses seabios.

Changing the ACPI table size causes migration to break, and the memory
hotplug work opened our eyes on how horribly we were breaking things in
2.0 already.
The ACPI table size is rounded to the next 4k, which one would think
gives some headroom. In practice this is not the case, because the user
can control the ACPI table size (each CPU adds 97 bytes to the SSDT and
8 to the MADT) and so some "-smp" values will break the 4k boundary and
fail to migrate. Similarly, PCI bridges add ~1870 bytes to the SSDT.
This patch concerns itself with fixing migration from QEMU 2.0. It
computes the payload size of QEMU 2.0 and always uses that one.
The previous patch shrunk the ACPI tables enough that the QEMU 2.0 size
should always be enough; non-AML tables can change depending on the
configuration (especially MADT, SRAT, HPET) but they remain the same
between QEMU 2.0 and 2.1, so we only compute our padding based on the
sizes of the SSDT and DSDT.
Migration from QEMU 1.7 should work for guests that have a number of CPUs
other than 12, 13, 14, 54, 55, 56, 97, 98, 139, 140. It was already
broken from QEMU 1.7 to QEMU 2.0 in the same way, though.
Even with this patch, QEMU 1.7 and 2.0 have two different ideas of
"-M pc-i440fx-2.0" when there are PCI bridges. Igor sent a patch to
adopt the QEMU 1.7 definition. I think distributions should apply
it if they move directly from QEMU 1.7 to 2.1+ without ever packaging
version 2.0.

Right now starting a machine with virtio-scsi and a <= 2.0 machine type
fails with:
qemu-system-x86_64: -device virtio-scsi-pci: Property .any_layout not found
This is because the any_layout bit was actually never set after
virtio-scsi was changed to support arbitrary layout for virtio buffers.
(This was just a cleanup and a preparation for virtio 1.0; no guest
actually checks the bit, but the new request parsing algorithms are
tested even with old guest).

The memory allocation between hw/block/virtio-blk.c,
hw/block/dataplane/virtio-blk.c, and hw/virtio/dataplane/vring.c is
messy. Structs are allocated in different files than they are freed in.
This is risky and makes memory leaks easier.
Embed VirtQueueElement in VirtIOBlockReq to reduce the amount of memory
allocation we need to juggle. This also makes vring.c and virtio.c
slightly more similar.

Rename vring_free_element() to vring_unmap_element() since it no longer

The two common virtio features can be defined per bus, so move all
into bus class device to make code more clean.
As discussed with cornelia, s390-virtio-blk doesn't support
the two features at all, so keep s390-virtio as it.

When a device is unparented (i.e. made completely hidden from management)
we want to send a DEVICE_DELETED event only if the device actually was
realized. This avoids raising DEVICE_DELETED events when device_add
fails.
However, this does not work right for recursively-deleted
devices: the whole tree is _first_ unrealized, _then_ unparented.
Then device_unparent sees realized==false and fails to trigger
the event. The solution is simply to move have_realized into
the DeviceState struct. If device_add fails, we never set the
new field to true and DEVICE_DELETED is not sent.
Fixes qemu-iotests testcase 067 (broken by commit 5942a19, though that
commit in turn fixed a possible segfault in the same test).

There is no need to make DEFINE_VIRTIO_BLK_PROPERTIES() public. Inline
it into virtio-blk.c so it cannot be used by mistake from other source
files.

This function is no longer used since parent objects now use child
aliases to set the VirtIOBlkConf directly.

The qdev_alias_all_properties() function creates QOM alias properties
for each qdev property on a DeviceState. This is useful for parent
objects that wish to forward property accesses to their children.

Move the x-data-plane property. Originally it was outside since not
every transport may wish to support dataplane. But that makes little
sense when we have a dedicated CONFIG_VIRTIO_BLK_DATA_PLANE ifdef
already.
This move makes it easier to switch to property aliases in the next
patch.
