The global variable 'ram_size' is hidden by the local variable
declaration in s390_init(). Since we want to update the global
ram size in certain cases we must not use a local ram_size
variable.

Functionalities:
1 create a new image.
2 sync access of an image.
3 basic image information retrieving such as backing file.
4 detect if a sector is allocated in an image.

Libqblock was placed in new directory ./libqblock, libtool will build
dynamic library there, source files of block layer remains in ./block.
So block related source code will generate 3 sets of binary, first is old
ones used in qemu, second and third are non PIC and PIC ones in ./libqblock.

The data plane thread needs to map guest physical addresses to host
pointers. Normally this is done with cpu_physical_memory_map() but the
function assumes the global mutex is held. The data plane thread does
not touch the global mutex and therefore needs a thread-safe memory
mapping mechanism.
The virtio-blk-data-plane feature is easy to integrate into
hw/virtio-blk.c. The data plane can be started and stopped similar to
vhost-net.
Users can take advantage of the virtio-blk-data-plane feature using the

The raw_get_aio_fd() function allows virtio-blk-data-plane to get the
file descriptor of a raw image file with Linux AIO enabled. This
interface is really a layering violation that can be resolved once the

Outside the safety of the global mutex we need to poll on file
descriptors. I found epoll(2) is a convenient way to do that, although
other options could replace this module in the future (such as an
AioContext-based loop or glib's GMainLoop).

The virtio-blk-data-plane feature only works with Linux AIO. Therefore
add a ./configure option and necessary checks to implement this
dependency.

This series adds the -device virtio-blk-pci,x-data-plane=on property that
enables a high performance I/O codepath. A dedicated thread is used to process
virtio-blk requests outside the global mutex and without going through the QEMU
block layer.
Khoa Huynh reported an increase from 140,000 IOPS
The IOQueue has a pool of iocb structs and a function to add new
read/write requests. Multiple requests can be added before calling the
submit function to actually tell the host kernel to begin I/O. This
allows callers to batch requests and submit them in one go.
The actual I/O is performed usin

Add presave/postload hooks to the ARM GIC common base class.
These will be used by the KVM in-kernel GIC subclass to sync
state between kernel and userspace when migrating.

When using an in-kernel GIC with KVM, we need to tell the kernel where
the GIC's memory mapped registers live. Do this by registering a
MemoryListener which tracks where the board model maps the A15's
private peripherals, so we can finish the GIC initialisation
when the GIC is actually mapped.

This commit adds the ARM KVM headers. This is not to go to QEMU
upstream -- the correct path there is that the KVM code will be
committed to a mainline upstream kernel, and then upstream QEMU
can do a bulk header update from the upstream kernel, which will
allow us to drop this temporary commit.

Add support for saving and restoring VFP register state from the
kernel. This includes a check that the KVM-created CPU has full
VFP support (as the TCG Cortex-A15 model always does), since for
the moment ARM QEMU doesn't have any way to tweak optional features
on created CPUs.
