5d0e2280cc acpi.pci,pc,memory core fixes
Most notably this includes changes to exec to support
 full 64 bit addresses.
 
 This also flushes out patches that got queued during 1.7 freeze.
 There are new tests, and a bunch of bug fixes all over the place.
 There are also some changes mostly useful for downstreams.
 
 I'm also listing myself as pc co-maintainer. I'm doing this reluctantly,
 but this seems to be necessary to make sure patches are not lost or delayed too
 much, and posting the MAINTAINERS patch did not seem to make anyone else
 volunteer.

7a10ef51c2 hpet: enable to entitle more irq pins for hpet
Owning to some different hardware design, piix and q35 need
different compat. So making them diverge.

On q35, IRQ2/8 can be reserved for hpet timer 0/1. And pin 16~23
can be assigned to hpet as guest chooses. So we introduce intcap
property to do that.

Consider the compat and piix/q35, we finally have the following
value for intcap: For piix, hpet's intcap is hard coded as IRQ2.
For pc-q35-1.7 and earlier, we use IRQ2 for compat reason. Otherwise
IRQ2, IRQ8, and IRQ16~23 are allowed.

b29ad07ee8 smbios: Set system manufacturer, product & version by default
Currently, we get SeaBIOS defaults: manufacturer Bochs, product Bochs,
no version.  Best SeaBIOS can do, but we can provide better defaults:
manufacturer QEMU, product & version taken from QEMUMachine desc and
name.

Take care to do this only for new machine types, of course.

Note: Michael Tsirkin doesn't trust us to keep values of QEMUMachine member
product stable in the future.  Use copies instead, and in a way that
makes it obvious that they're guest ABI.

Note that we can be trusted to keep values of member name, because
that has always been ABI.

d4fce24f3a qtest: split configuration of qtest accelerator and chardev
qtest uses the icount infrastructure to implement a test-driven vm_clock.  This
however is not necessary when using -qtest as a "probe" together with a normal
TCG-, KVM- or Xen-based virtual machine.  Hence, split out the call to
configure_icount into a new function that is called only for "-machine
accel=qtest"; and disable those commands when running with an accelerator
other than qtest.

This also fixes an assertion failure with "qemu-system-x86_64 -machine
accel=qtest" but no -qtest option.  This is a valid case, albeit somewhat
weird; nothing will happen in the VM but you'll still be able to
interact with the monitor or the GUI.

Now that qtest_init is not limited to an int(void) function, change
global variables that are not used outside qtest_init to arguments.

And finally, cleanup useless parts of include/sysemu/qtest.h.  The file
is not used at all for user-only emulation, and qtest is not available
on Win32 due to its usage of sigwait.

5e96f5d2f8 virtio-bus: cleanup plug/unplug interface
Right now we have these pairs:

- virtio_bus_plug_device/virtio_bus_destroy_device.  The first
  takes a VirtIODevice, the second takes a VirtioBusState

- device_plugged/device_unplug callbacks in the VirtioBusClass
  (here it's just the naming that is inconsistent)

- virtio_bus_destroy_device is not called by anyone (and since
  it calls qdev_free, it would be called by the proxies---but
  then the callback is useless since the proxies can do whatever
  they want before calling virtio_bus_destroy_device)

And there is a k->init but no k->exit, hence virtio_device_exit is
overwritten by subclasses (except virtio-9p).  This cleans it up by:

- renaming the device_unplug callback to device_unplugged

- renaming virtio_bus_plug_device to virtio_bus_device_plugged,
  matching the callback name

- renaming virtio_bus_destroy_device to virtio_bus_device_unplugged,
  removing the qdev_free, making it take a VirtIODevice and calling it
  from virtio_device_exit

- adding a k->exit callback

virtio_device_exit is still overwritten, the next patches will fix that.

now is qemu-img, and it is not impacted by introduce function
bdrv_snapshot_load_tmp_by_id_or_name() that call bdrv_snapshot_load_tmp()

539891a85d xen-pvdevice: make device-id property compulsory
The intention of the Xen PV device is that it is used as a parent
device for PV drivers in Xen HVM guests and the set of PV drivers that
bind to the device is determined by its device ID (and possibly
vendor ID and revision). As such, the device should not have a default
device ID, it should always be supplied by the Xen toolstack.

b3af018f3b sheepdog: support user-defined redundancy option
Sheepdog support two kinds of redundancy, full replication and erasure coding.

# create a fully replicated vdi with x copies
 -o redundancy=x (1 <= x <= SD_MAX_COPIES)

# create a erasure coded vdi with x data strips and y parity strips
 -o redundancy=x:y (x must be one of {2,4,8,16} and 1 <= y < SD_EC_MAX_STRIP)

E.g, to convert a vdi into sheepdog vdi 'test' with 8:3 erasure coding scheme

$ qemu-img convert -o redundancy=8:3 linux-0.2.img sheepdog:test

e4654d2d94 block: per caller dirty bitmap
Previously a BlockDriverState has only one dirty bitmap, so only one
caller (e.g. a block job) can keep track of writing. This changes the
dirty bitmap to a list and creates a BdrvDirtyBitmap for each caller, the
lifecycle is managed with these new functions:

    bdrv_create_dirty_bitmap
    bdrv_release_dirty_bitmap

Where BdrvDirtyBitmap is a linked list wrapper structure of HBitmap.

In place of bdrv_set_dirty_tracking, a BdrvDirtyBitmap pointer argument
is added to these functions, since each caller has its own dirty bitmap:

    bdrv_get_dirty
    bdrv_dirty_iter_init
    bdrv_get_dirty_count

bdrv_set_dirty and bdrv_reset_dirty prototypes are unchanged but will
internally walk the list of all dirty bitmaps and set them one by one.

d75cbb5e68 block: introduce bdrv_make_zero
this patch adds a call to completely zero out a block device.
the operation is sped up by checking the block status and
only writing zeroes to the device if they currently do not
return zeroes. optionally the zero writing can be sped up
by setting the flag BDRV_REQ_MAY_UNMAP to emulate the zero
write by unmapping if the driver supports it.
