Note this fixes 2 things in one go, first of all the device_destroy bus
op should be a device_detach bus op, as pending async packets from the
device should be cancelled on detach not on destroy.
Secondly having this as a bus op won't work with companion controllers, since
then there will be 1 bus driven by the ehci controller and thus 1 set of bus
ops, but the device being detached may be downstream of a handed over port.
Making the detach of a downstream device a port op allows the ehci controller
to forward this to the companion controller port for handed over ports.

This makes them consistent with the attach and detach ops, and in general
it makes sense to make portops take a port as argument. This also makes
adding support for a companion controller easier / cleaner.

Cleanup / preparation patch for companion controller support. Note that
as a "side-effect" this patch also fixes the milkymist-softusb controller
not having a port_location set for its ports.

In musb_packet() handle final processing of non-asynchronous
USB packets by directly calling musb_schedule_cb() rather than
going through usb_packet_complete(). The latter will trigger
an assertion because the packet doesn't belong to a device.

Parameter 'info' is const, so add the missing attribute.
v2:
Add 'const' to the local variable info in do_cpu_reset() and to
the boot_info field in CPUARMState (suggested by Peter Maydell).

If I start qemu with:
# qemu -hda disks/test.img -enable-kvm -m 1G -snapshot \
-device virtio-serial \
-chardev socket,host=localhost,port=1234,server,nowait,id=foo \
-device virtserialport,chardev=foo,name=org.qemu.guest_agent
I get a segfault when booting a Fedora 14 guest. The backtrace says:
Program terminated with signal 11, Segmentation fault.
#0 0x0000000000420850 in handle_control_message (vser=0x3732bd0, buf=0x2c173e0, len=8) at /home/lcapitulino/src/qmp-unstable/hw/virtio-serial-bus.c:335
335 info = DO_UPCAST(VirtIOSerialPortInfo, qdev, port->dev.info);
What's happening is VIRTIO_CONSOLE_DEVICE_READY is a message for the
whole device, not for an individual port. So port is NULL. This bug was
introduced by commit a15bb0d6a981de749452a5180fc8084d625671da.
This commit fixes that by making the port returned by find_port_by_id()
be used only by the VIRTIO_CONSOLE_PORT_READY and
VIRTIO_CONSOLE_PORT_OPEN messages.

- do not use Linux headers on non-Linux hosts
- fix kvmclock for !CONFIG_KVM
- fix s390 build on non-Linux hosts

Correct a number of minor errors in the OHCI wakeup implementation:
* when the port is suspended but the controller is not, raise RHSC
* when the controller is suspended but the port is not, raise RD
* when the controller is suspended, move it to resume state
These fix some edge cases where a USB device might not successfully get
the attention of the guest OS if it tried to do so at the wrong time.

This is used to indicate at which speed[s] the device can operate,
so that this can be checked to match the ports capabilities when it gets
attached to a bus.
Note that currently all usb1 emulated device claim to be fullspeed, this
seems to not cause any problems, but still seems wrong, because with real
hardware keyboards, mice and tablets usually are lo-speed, so reporting these
as fullspeed devices seems wrong.

Add properties for the wakeup rate and the max number of frames ehci
will process at once.
The wakeup rate defaults to 1000 which equals the usb frame rate. This
can be reduced to make qemu wake up less often when ehci is active.
In case the wakeup rate is reduced or the ehci timer is delayed due to
latency issues elsewhere in qemu ehci will process multiple frames at
once. The maxframes property specifies the upper limit for this.

Diagnose the case where the user asked for a NIC via "-net nic"
but the board didn't instantiate that NIC (for example where the
user asked for two NICs but the board only supports one). Note
that this diagnostic doesn't apply to NICs created through -device,
because those are always instantiated.

When running kvm-autotest, fputc() is often the second highest (sometimes #1)
function showing up in a profile. This is due to fputc() locking the file
for every byte written.
Optimize by buffering a line's worth of pixels and writing that out in a
single call.

Compared to the last version I only added a comment to the code.
- remove i440FX-xen and i440fx_write_config_xen
we don't need to intercept pci config writes to i440FX anymore;
- introduce PIIX3-xen and piix3_write_config_xen
we do need to intercept pci config write to the PCI-ISA bridge to update
the PCI link routing;
- set the number of PIIX3-xen interrupts line to 128;

Until now, we've created a union over multiple different TLB types and
allocated that union. While it's a waste of memory (and cache) to allocate
TLB information for a TLB type with much information when you only need
little, it also inflicts another issue.
With the new KVM API, we can now share the TLB between KVM and qemu, but
for that to work we need to have both be in the same layout. We can't just
stretch it over to fit some internal different TLB representation.
Hence this patch moves all TLB types to their own array, allowing us to only
address and allocate exactly the boundaries required for the specific TLB
type at hand.

We have some KVM interaction code in Qemu that tries to be clever and
ignore some capabilities when running on BookE style MMUs. Unfortunately,
the default CPU bamboo was defaulting to was not a BookE-style MMU,
resulting in the check to fail.
With this patch, guests can run again on 440 with -enable-kvm.

The natural format for e500 cores to do TLB manipulation with are the MAS
registers. Instead of converting them into some internal representation
and back again when the guest reads them, we can just keep the data
identical to the way the guest passed it to us.
The main advantage of this approach is that we're getting closer to being
able to share MMU data with KVM using shared memory, so that we don't need
to copy lots of MMU data back and forth all the time. For this to work
however, another patch is required that gets rid of the TLB union, as that
destroys our memory layout that needs to be identical with the kernel one.

When running a PPC guest with KVM that can do PV operations, we need
to indicate the guest which instructions to use for a hypercall and
that it is running as KVM guest.
This logic was available on openbios based machines already. This patch
also adds said functionality to the mpc8544ds machine.

During testing, I was generating a vmlinux binary that easily occupied
more than 20MB of RAM. Since the current -kernel code loads the initrd
at a fixed address behind the kernel, we were overwriting kernel data
when the kernel got too big.
To finally get rid of the issue, let's calculate the initrd and cmdline
addresses relative to the kernel size, so we can have kernels and initrds
that are as big as they want to - as long as they fit in RAM.

When Linux reboots an e500 VM, it writes to a magic register in the
"global-utilities" device indicated by the device tree. We were not
emulating that device so far, rendering the VM reboot-less.
This patch implements that device with only the reboot functionality
implemented and adds it to the device tree. With this patch applied,
I can successfully reboot a -M mpc8544ds VM.
