482f38b948 acpi: fix incorrect encoding for 0x{F-1}FFFF
Fix typo in build_append_int() which causes integer
truncation when it's in range 0x{F-1}FFFF by packing it
as WordConst instead of required DWordConst.

In partucular this fixes a regression: hotplug in slots 16,17,18 and 19
didn't work, since SSDT had code like this:

                If (And (Arg0, 0x0000))
                {
                    Notify (S80, Arg1)
                }

edc2438512 virtio-net: fix guest-triggerable buffer overrun
When VM guest programs multicast addresses for
a virtio net card, it supplies a 32 bit
entries counter for the number of addresses.
These addresses are read into tail portion of
a fixed macs array which has size MAC_TABLE_ENTRIES,
at offset equal to in_use.

To avoid overflow of this array by guest, qemu attempts
to test the size as follows:
-    if (in_use + mac_data.entries <= MAC_TABLE_ENTRIES) {

however, as mac_data.entries is uint32_t, this sum
can overflow, e.g. if in_use is 1 and mac_data.entries
is 0xffffffff then in_use + mac_data.entries will be 0.

Qemu will then read guest supplied buffer into this
memory, overflowing buffer on heap.

7dc176bce4 hw/pci-host/prep: Don't reverse IO accesses on bigendian hosts
The raven_io_read() and raven_io_write() functions pass and
return values in little-endian format (since the IO op struct
is marked DEVICE_LITTLE_ENDIAN); however they were storing the
values in the buffer to pass to address_space_read/write()
in host-endian order, which meant that on big-endian hosts
the values were inadvertently reversed. Use the *_le_p()
accessors instead so that we are consistent regardless of
host endianness.

Strictly speaking the byte order of the buffer for
address_space_rw() is target byte order (which for PPC
will be BE) but it doesn't actually matter as long as we
are consistent about the marking on the IO op struct and
which stl_*_p().

This bug was probably introduced due to confusion caused by
the two different versions of ldl_p() and friends:
 bswap.h defines versions meaning "host endianness access"
 cpu-all.h defines versions meaning "target endianness access"
As a target-independent source file prep.c gets the bswap.h
versions; the very similar looking code in ioport.c is
compiled per-target and gets the cpu-all.h versions.

e81a982aa5 PPC: Clean up DECR implementation
There are 3 different variants of the decrementor for BookE and BookS.

The BookE variant sets TSR[DIS] to 1 when the DEC value becomes 1 or 0. TSR[DIS]
is then the indicator whether the decrementor interrupt line is asserted or not.

The old BookS variant treats DEC as an edge interrupt that gets triggered when
the DEC value's top bit turns 1 from 0.

The new BookS variant maintains the assertion bit inside DEC itself. Whenever
the DEC value becomes negative (top bit set) the DEC interrupt line is asserted.

So far we implemented mostly the old BookS variant. Let's do them all properly.

This fixes booting pseries ppc64 guest images in TCG mode for me.

54bee5c2b4 dataplane: replace iothread object_add() with embedded instance
Before IOThread was its own object, each virtio-blk device would create
its own internal thread.  We need to preserve this behavior for
backwards compatibility when users do not specify -device
virtio-blk-pci,iothread=<id>.

This patch changes how the internal IOThread object is created.
Previously we used the monitor object_add() function, which is really a
layering violation.  The problem is that this needs to assign a name but
we don't have a name for this internal object.

Generating names for internal objects is a pain but even worse is that
they may collide with user-defined names.

Paolo Bonzini <pbonzini@redhat.com> suggested that the internal IOThread
object should not be named.  This way the conflict cannot happen and we
no longer need object_add().

One gotcha is that internal IOThread objects will not be listed by the
query-iothreads command since they are not named.  This is okay though
because query-iothreads is new and the internal IOThread is just for
backwards compatibility.  New users should explicitly define IOThread
objects.

qemu-system-x86_64: hw/pci/pci.c:250: pcibus_reset: Assertion
`bus->irq_count[i] == 0' failed.

pci_device_deassert_intx should clear irq_state anyways, so add
an assert.

This fixes migration with usb2 + usb-tablet.

3b6144bdbb acpi,pc,build bug fixes
Here are some bugfixes for 2.0.
 
 A bugfix for acpi for pci bridges, and a build fix for
 old systems without pthread_setname_np: both fix regressions
 so we definitely want to include them.
 HPET fix is not for a regression but looks very safe,
 fixes a nasty bug and has been on list for a while.

    acpi-build: append description for non-hotplug
appended description for all occupied non hotpluggable PCI slots.
However the bridge devices are already added to SSDT,
adding them again will create an incorrect SSDT table.

Fixed by skipping the pci bridge devices, marking them as 'system'.

c36ad13fe9 Don't enable a HPET timer if HPET is disabled
A HPET timer can be started when HPET is not yet
enabled. This will not generate an interrupt
to the guest, but causes problems when HPET is later
enabled.

A timer that is created and expires at least once before
HPET is enabled will have an initialized comparator based
on a hpet_offset of 0 (uninitialized). When HPET is
enabled, hpet_set_timer() is called a second time, which
modifies the timer expiry to a time based on the
difference between current ticks (measured with the
newly initialized hpet_offset) and the timer's
comparator (which was generated before hpet_offset was
initialized). This results in a long period of no HPET
timer ticks.

When this occurs with a CentOS 5.x guest, the guest
may not receive timer interrupts during its narrow
timer check window and panic on boot.

d4715c4183 hw/arm: Stop specifying integratorcp as the default board
Currently for both qemu-system-arm and qemu-system-aarch64
the default board model if the user doesn't specify one
is the 'integratorcp'. This is a totally arbitrary historical
accident since it was the first board to be modelled.
That board is now just one target among many for us, and
is a very poor choice of default:
 * it's an ancient board that is now only found in the
   junkpiles of longtime ARM/Linux hackers, if at all
 * it's an ARMv5 CPU, when most distros are now assuming
   ARMv7
 * it's pretty much unmaintained in QEMU
 * it doesn't even have versatilepb's advantage of
   supporting PCI

Making it or any other board the default serves only
to confuse people new to ARM who expect something more
like the x86 monoculture. Remove the is_default marker
from integratorcp, and don't set it for any other board,
to give users a nudge that they need to think about
which board they want a QEMU model of. (QEMU will produce
the admittedly slightly cryptic error "No machine found.")

f7bc8ef809 virtio-net: add vlan receive state to RxFilterInfo
Stefan Fritsch just fixed a virtio-net driver bug [1], virtio-net won't
filter out VLAN-tagged packets if VIRTIO_NET_F_CTRL_VLAN isn't negotiated.

This patch added a new field to @RxFilterInfo to indicate vlan receive
state ('normal', 'none', 'all'). If VIRTIO_NET_F_CTRL_VLAN isn't
negotiated, vlan receive state will be 'all', then all VLAN-tagged packets
will be received by guest.

This patch also fixed a boundary issue in visiting vlan table.
