Allow write operations on behalf of the initiator. The
precursor to write is the sending of the write metadata
that consists of the ObjectInfo dataset. This patch introduces
a flag that is set when the responder is ready to receive
write data based on a previous SendObjectInfo operation by
the initiator (The SendObjectInfo implementation is in a
later patch)

Write of existing objects by the initiator is acheived by
making a temporary buffer with the new changes, deleting the
old file and then writing a new file with the same name.
Also, add a "readonly" property which needs to be set to false
for deletion to work.

The option have been marked as deprecated since QEMU 2.10, and so far
nobody complained that the host, serial, disk and net options are urgently
required anymore. So let's now get rid at least of this legacy pile, to
simplify the usb code quite a bit.
This patch removes the usbdevices host, serial, disk and net. These devices
use their own complicated parameter parsing mechanisms, so they are just
ugly to maintain, without real benefit for the users (the users can use the
corresponding "-device" parameters instead which have the same complexity
as the "-usbdevice" devices here).
Note that the other rather simple -usbdevice options (mouse, tablet, etc.)
are not removed yet (the code is really simple here, so it does not hurt
much to keep it), as well as the two devices "braille" and "bt" which are
easier to use with -usbdevice than with -device.

The bus pointer in PCIDevice is basically redundant with QOM information.
It's always initialized to the qdev_get_parent_bus(), the only difference
is the type.
Therefore this patch eliminates the field, instead creating a pci_get_bus()
helper to do the type mangling to derive it conveniently from the QOM
Device object underneath.

Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of
TYPE_PCI_DEVICE, except:
1) The ones that already have INTERFACE_PCIE_DEVICE set:
* base-xhci
* e1000e
* nvme
* pvscsi
* vfio-pci
* virtio-pci
* vmxnet3
2) base-pci-bridge
Not all PCI bridges are Conventional PCI devices, so
INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes
that are actually Conventional PCI:
* dec-21154-p2p-bridge
* i82801b11-bridge
* pbm-bridge
* pci-bridge
The direct subtypes of base-pci-bridge not touched by this patch
are:
* xilinx-pcie-root: Already marked as PCIe-only.
* pcie-pci-bridge: Already marked as PCIe-only.
* pcie-port: all non-abstract subtypes of pcie-port are already
marked as PCIe-only devices.
3) megasas-base
Not all megasas devices are Conventional PCI devices, so the
interface names are added to the subclasses registered by
megasas_register_types(), according to information in the
megasas_devices[] array.
"megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add
INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

Modify the pre_save method on VMStateDescription to return an int
rather than void so that it potentially can fail.
Changed zillions of devices to make them return 0; the only
case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already
had an error_report/return case.
Note: If you add an error exit in your pre_save you must emit
an error_report to say why.

But we know that there are at most 5 levels of USB hubs, with at
most two digits per level; that plus the separating dots means we
use at most 15 bytes (including trailing NUL) of our 16-byte field.
Adding an assertion to show gcc that we checked for truncation is
enough to shut up the false-positive warning.

In some cases a failing VMSTATE_*_EQUAL does not mean we detected a bug,

Let's introduce infrastructure for specifying a error hint to be used if
equal check fails. Let's do this by adding a parameter to the _EQUAL
macros called _err_hint. Also change all current users to pass NULL as
last parameter so nothing changes for them.

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

The spec says:
Suspend: (PORT_SUSPEND) This field indicates whether or not the device
on this port is suspended. Setting this field causes the device to
suspend by not propagating bus traffic downstream. This field may be
reset by a request or by resume signaling from the device attached to
the port.
I can't find any specific statement like "the PORT_SUSPEND field is reset
automatically on remote wakeup", but without this patch, the only way to
reset it is via the ClearPortFeature request so the ".. or by resume
signaling from the device" clause is clearly not implemented on the remote
wakeup path.
The default xhci Windows driver does not issue the ClearPortFeature request
and suspended devices attached to a hub don't properly get out of the
suspended state. Interestingly, the default uhci Windows driver *does*
issue the ClearPortFeature request and does not exhibit this problem.

When done processing a endpoint ring we must update the dequeue pointer
in the endpoint context in guest memory. This is needed to make sure
the guest has a correct view of things and also to make live migration
work properly, because xhci post_load restores alot of the state from
xhci data structures in guest memory.
Add xhci_set_ep_state() call to do that.
The recursive calls stopped by commit
ddb603ab6c had the (unintentional) side
effect to hiding this bug. xhci_set_ep_state() was called before
processing, to set the state to running, which updated the dequeue
pointer too.

Place a 'dc->vmsd' check prior to it so that we do not segfault for

The qemu xhci emulation doesn't handle the ERDP_EHB flag correctly.
When the host adapter queues a new event the ERDP_EHB flag is set. The
flag is cleared (via w1c) by the guest when it updates the ERDP (event
ring dequeue pointer) register to notify the host adapter which events
it has fetched.
An IRQ must be raised in case the ERDP_EHB flag flips from clear to set.
If the flag is set already (which implies there are events queued up
which are not yet processed by the guest) xhci must *not* raise a IRQ.
Qemu got that wrong and raised an IRQ on every event, thereby generating
spurious interrupts in case we've queued events faster than the guest
processed them. This patch fixes that.
With that change in place we also have to check ERDP updates, to see
whenever the guest has fetched all queued events. In case there are
still pending events set ERDP_EHB and raise an IRQ again, to make sure
the events don't linger unseen forever.
The linux kernel driver and the microsoft windows driver (shipped with
win8+) can deal with the spurious interrupts without problems. The
renesas windows driver (v2.1.39) which can be used on older windows
versions is quite upset though. It does spurious ERDP updates now and
then (not every time, seems we must hit a race window for this to
happen), which in turn makes the qemu xhci emulation think the event
ring is full. Things go south from here ...
tl;dr: This is the "fix xhci on win7" patch.

1. Set bInterfaceProtocol to 0x00 for usb-tablet. This should be
non-zero for boot protocol devices only, which the usb-tablet is not.
2. Set the usb-tablet's usage to "mouse" in the report descriptor.
The boot protocol of 0x02 specifically confused OS X/macOS' HID driver
stack, causing it to generate additional bogus HID events with relative
motion in addition to the tablet's absolute coordinate events.
Absolute pointing devices with HID Report Descriptor usage of 0x01
(pointing) are treated by the macOS HID driver as analog sticks, and
absolute coordinates are not directly translated to absolute mouse
cursor positions. Changing it to 0x02 (mouse) fixes the problem, and
does not have any adverse effect in other operating systems and
windowing systems. (VMWare does the same thing.)

This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc

Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170202' into staging
ppc patch queue 2017-02-02
This obsoletes ppc-for-2.9-20170112, which had a MacOS build bug.
This is a long overdue ppc pull request for qemu-2.9. It's been a
long time coming due to some holidays and inconveniently timed
problems with testing. So, there's a lot in here:
* More POWER9 instruction implementations for TCG
* The simpler parts of my CPU compatibility mode cleanup
* This changes behaviour to prefer compatibility modes over
"raW" mode for new machine type versions
* New "40p" machine type which is essentially a modernized and
cleaned up "prep". The intention is that it will replace "prep"
once it has some more testing and polish.
* Add pseries-2.9 machine type
* Implement H_SIGNAL_SYS_RESET hypercall
* Consolidate the two alternate CPU init paths in pseries by
making it always go through CPU core objects to initialize CPU
* A number of bugfixes and cleanups
* Stop the guest timebase when the guest is stopped under KVM.
This makes the guest system clock also stop when paused, which
matches the x86 behaviour.
* Some preliminary cleanups leading towards implementation of the
POWER9 MMU.
There are also some changes not strictly related to ppc code, but for
its benefit:
* Limit the pxi-expander-bridge (PXB) device to x86 guests only
(it's essentially a hack to work around historical x86
limitations)
* Some additions to the 128-bit math in host_utils, necessary for
some of the new instructions.
* Revise a number of qtests and enable them for ppc

msix_init() reports errors with error_report(), which is wrong when
it's used in realize(). The same issue was fixed for msi_init() in
commit 1108b2f. In order to make the API change as small as possible,
leave the return value check to later patch.
For some devices(like e1000e, vmxnet3, nvme) who won't fail because of
msix_init's failure, suppress the error report by passing NULL error
object.
Bonus: add comment for msix_init.

usb_xhci_realize() corrects invalid values of property "intrs"
automatically, but the uncorrected value is passed to msi_init(),
which chokes on invalid values. Delay that until after the
correction.
Resources allocated by usb_xhci_init() are leaked when msi_init()
fails. Fix by calling it after msi_init().

When passing through an USB storage device to a pseries guest, it
is currently not possible to automatically boot from the device
if the "bootindex" property has been specified, too (e.g. when using
"-device nec-usb-xhci -device usb-host,hostbus=1,hostaddr=2,bootindex=0"
at the command line). The problem is that QEMU builds a device tree path
like "/pci@800000020000000/usb@0/usb-host@1" and passes it to SLOF
in the /chosen/qemu,boot-list property. SLOF, however, probes the
USB device, recognizes that it is a storage device and thus changes
its name to "storage", and additionally adds a child node for the
SCSI LUN, so the correct boot path in SLOF is something like
"/pci@800000020000000/usb@0/storage@1/disk@101000000000000" instead.
So when we detect an USB mass storage device with SCSI interface,
we've got to adjust the firmware boot-device path properly that
SLOF can automatically boot from the device.

The vmstate_pci_device and vmstate_pcie_devices differ
just in the size of one buffer; combine the two using a _TEST
macro.
I think this is safe as long as everywhere which currently
uses either of these two uses the right type.
One thing that concerns me is that some places use pci_device_load/save
which does some irq mangling, but others just use the VMSTATE_PCI_DEVICE
macro - how are they getting the same irq mangling?
This passes a smoke test migrate of:

The default DMA offset is set to 3. When the property is not set by
the consumer, the default causes DMA access to be shifted by 3
bytes. In PXA, this results in incorrect DMA access, leading to error
notification in the USB controller driver. A better default would be
0, so that there is no offset, when the consumer does not specify one.

snprintf return value is *not* the number of chars written into the
buffer, but the number of chars needed. So in case the buffer is too
small you can go alloc a bigger one and try again. But that also means
you can't simply use the return value for the next snprintf call
without checking beforehand that things did actually fit.
Problem is that usb_desc_create_serial didn't perform that check, so a
loooong path string (can happen with deep pci-bridge nesting) results in
the third snprintf call smashing the stack.
Fix this by throwing out all the snpintf calls and use g_strdup_printf
instead.

xhci has a fixed number of 24 (TD_QUEUE) XHCITransfer structs per
endpoint, which turns out to be a problem for usb3 devices with 32 (or
more) bulk streams. xhci re-checks the trb rings on every finished
transfer to make sure it'll pick up any pending work. But that scheme
breaks in case the first transfer of a ring can't be started because we
ran out of XHCITransfer structs already.
So remove static XHCITransfer array from XHCIEPContext. Use a linked
list instead, and allocate/free XHCITransfer as needed. Add helper
functions to allocate & initialize and to cleanup & release
XHCITransfer structs. That also simplifies trb management, we never
have to realloc XHCITransfer->trbs because we don't reuse XHCITransfer
structs any more.
New dynamic limit for in-flight xhci transfers per endpoint is
number-of-streams + 16.

The qemu_chr_fe_write method will return -1 on EAGAIN if the
chardev backend write would block. Almost no callers of the
qemu_chr_fe_write() method check the return value, instead
blindly assuming data was successfully sent. In most cases
this will lead to silent data loss on interactive consoles,
but in some cases (eg RNG EGD) it'll just cause corruption
of the protocol being spoken.
We unfortunately can't fix the virtio-console code, due to
a bug in the Linux guest drivers, which would cause the
entire Linux kernel to hang if we delay processing of the
incoming data in any way. Fixing this requires first fixing
the guest driver to not hold spinlocks while writing to the

When unplugging a device in the Xen pvusb backend drain the submit
queue before deallocation of the control structures. Otherwise there
will be bogus memory accesses when I/O contracts are finished.
Correlated to this issue is the handling of cancel requests: a packet
cancelled will still lead to the call of complete, so add a flag
to the request indicating it should be just dropped on complete.

ehci_update_frindex takes time linearly proportional to a number
of uframes to calculate new frame index and raise FLR interrupts,
which is a problem for large amounts of uframes.
If we experience large delays between echi timer callbacks (i.e. because
other periodic handlers have taken a lot of time to complete) we
get a lot of skipped frames which then delay ehci timer callback more
and this leads to deadlocking the system when ehci schedules next
callback to be too soon.
Observable behaviour is qemu consuming 100% host CPU time while guest
is unresponsive. This misbehavior could happen for a while and QEMU does
not get out from this state automatically without the patch.
This change makes ehci_update_frindex execute in constant time.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

If a node name instead of a BlockBackend name is specified as the driver
for a guest device, an anonymous BlockBackend is created now.
The order of operations in release_drive() must be reversed in order to
avoid a use-after-free bug because now blk_detach_dev() frees the last
reference if an anonymous BlockBackend is used.
usb-storage uses a hack where it forwards its BlockBackend as a property
to another device that it internally creates. This hack must be updated
so that it doesn't drop its original BB before it can be passed to the
other device. This used to work because we always had the monitor
reference around, but with node-names the device reference is the only
one now.

Use stl_le_p() and ldl_le_p() to read and write data from
buffers, rather than using pointer casts and cpu_to_le32()
for writes and le32_to_cpup() for reads. This:
* avoids lots of casts
* works even if the buffer isn't as aligned as the host would like
* avoids using the *_to_cpup() functions which we want to get rid of
Note that there may still be some places where a pointer from the
guest is cast to a pointer to a host structure; these would also
have to be changed for the device to work on a host CPU which
enforces alignment restrictions.

This patch changes usb-host behavior in case we hostbus= and hostaddr=
properties are used to identify the usb device in question. Instead of
adding the device to the hotplug watchlist we try to open directly using
the given bus number and device address.
Putting a device specified by hostaddr to the hotplug watchlist isn't
a great idea as the address isn't a fixed property. It changes every
time the device is plugged in. So considering this case as "use the
device at bus:addr _now_" is more sane. Also usb-host will throw errors
in case it can't initialize the host device.
Note: For devices on the hotplug watchlist (hostport or vendorid or
productid specified) qemu continues to ignore errors and keeps
monitoring the usb bus to see if the device eventually shows up.

This patch is a rough fix to a memory corruption we are observing when
running VMs with xhci USB controller and OVMF firmware.
Specifically, on the following call chain
xhci_reset
xhci_disable_slot
xhci_disable_ep
xhci_set_ep_state
QEMU overwrites guest memory using stale guest addresses.
This doesn't happen when the guest (firmware) driver sets up xhci for
the first time as there are no slots configured yet. However when the
firmware hands over the control to the OS some slots and endpoints are
already set up with their context in the guest RAM. Now the OS' driver
resets the controller again and xhci_set_ep_state then reads and writes
that memory which is now owned by the OS.
As a quick fix, skip calling xhci_set_ep_state in xhci_disable_ep if the
device context base address array pointer is zero (indicating we're in
the HC reset and no DMA is possible).

Problem is now the check fires too often, it raises error IRQs even for

So, lets move down the check a bit, so it is done only for active TDs,

This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed. This replacement improves the readability and
understandability of code.
For example,
timer_mod(fdctrl->result_timer,
qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));
NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef. Since then, we've moved to include qemu/osdep.h
everywhere. Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h. That's in excess of
100KiB of crap most .c files don't actually need.
Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h. Include qapi/error.h in .c files that need it and don't
get it now. Include qapi-types.h in qom/object.h for uint16List.
Update scripts/clean-includes accordingly. Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h
comment quoted above similarly.
This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third. Unfortunately, the number depending on
qapi-types.h shrinks only a little. More work is needed for that one.

pid can be gotten from uhci device memory in uhci_handle_td(),
so the guest can trigger assert qemu if we get an invalid pid.
And the uhci spec 2.1.2 tells us The Host Controller sets Host
Controller Process Error bit to 1 when it detects a fatal error
and indicates that the Host Controller suffered a consistency
check failure while processing a Transfer Descriptor. An example
of a consistency check failure would be finding an illegal PID
field while processing the packet header portion of the TD.
When this error occurs, the Host Controller clears the Run/Stop
bit in the Command register to prevent further schedule execution.
We'd better to set UHCI_STS_HCPERR and kick an interrupt, check
the pid value at the first of uhci_handle_td function.

Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.
Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp). This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order. It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.
Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.
Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.
Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
$ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings'). The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

After clearing the status register we also have to update the irq line
status. Otherwise a irq which happends to be pending at reset time
causes a interrupt storm. And the guest can't stop as the status
register doesn't indicate any pending interrupt.
Both NetBSD and FreeBSD hang on shutdown because of that.

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.
This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_suspend(): the function stop the operation and acknowledge
pending interrupts (but doesn't disable it). Later in the function,
the device is moved to OHCI_SUSPEND_STATE, and the driver to
OHCI_RH_SUSPENDED. If between the moment when the interrupt is
acknowledged and the moment when the device is suspended a new
interrupt is raised, it will be never acknowledged because the
driver is now not in OHCI_RH_RUNNING state.

On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.
This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.
This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)
Some details:
- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
So if this interrupt happens and the driver is not in this state,
the function is called again and again, moving the system to a
CPU starvation.
- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
In QEMU this start the SOF timer and QEMU starts to send IRQs. As
the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
the ohci_irq() can be called and the driver never moved to
OHCI_STATE_RUNNING.
