This shows how the script deals with substructures added to vmstate
descriptions that don't change the on-wire format.

This script compares the vmstate dumps in JSON format as output by QEMU
with the -dump-vmstate option.
It flags various errors, like version mismatch, sections going away,
size mismatches, etc.
This script is tolerant of a few changes that do not change the on-wire
format, like embedding a few fields within substructs.
The script takes -s/--src and -d/--dest parameters, to which filenames
are given as arguments.
Example:
(in a qemu 2.0 tree):
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate qemu-2.0.json
(in a qemu 2.2 tree:)
./x86_64-softmmu/qemu-system-x86_64 -dump-vmstate -M pc-i440fx-2.0 \
qemu-2.2-m2.0.json
./scripts/vmstate-static-checker.py -s qemu-2.0.json -d qemu-2.2-m2.0.json
The script also takes a --reverse parameter to switch the src and dest
jsons. This is just a shorthand for reversing the src and dest.
The --help parameter shows usage information.

This commit adds a new command, '-dump-vmstate', that takes a filename
as an argument. When executed, QEMU will dump the vmstate information
for the machine type it's invoked with to the file, and quit.
The JSON-format output can then be used to compare the vmstate info for
different QEMU versions, specifically to test whether live migration
would break due to changes in the vmstate data.
A Python script that compares the output of such JSON dumps is included
in the following commit.

With virtio-blk dataplane, I/O errors might occur while QEMU is
not in the main I/O thread. However, it's invalid to call vm_stop
when we're neither in a VCPU thread nor in the main I/O thread,
even if we were to take the iothread mutex around it.
To avoid this problem, we can raise a request to the main I/O thread,
similar to what QEMU does when vm_stop is called from a CPU thread.
We know that bdrv_error_action is called from an AIO callback, and
the moment at which the callback will fire is not well-defined; it
depends on the moment at which the disk or OS finishes the operation,
which can happen at any time. Note that QEMU is certainly not in a CPU
thread and we do not need to call cpu_stop_current() like vm_stop() does.
However, we need to ensure that any action taken by management will
result in correct detection of the error _and_ a running VM. In particular:
- the event must be raised after the iostatus has been set, so that
"info block" will return an iostatus that matches the event.
- the VM must be stopped after the iostatus has been set, so that
"info block" will return an iostatus that matches the runstate.
The ordering between the STOP and BLOCK_IO_ERROR events is preserved;
BLOCK_IO_ERROR is documented to come first.
This makes bdrv_error_action() thread safe (assuming QMP events are,
which is attacked by a separate series).

There patch protects vmstop_requested with a lock and introduces
qemu_system_vmstop_request_prepare.
Together with the new call to qemu_vmstop_requested in vm_start,
qemu_system_vmstop_request_prepare avoids a race where the VM could remain
stopped even though the iostatus of a block device has already been set
(for example).
qemu_system_vmstop_request_prepare however also lets the caller thread
delay observation of the state change until it has itself communicated
that change to the user. This delay avoids any possibility of a wrong
reordering of the BLOCK_IO_ERROR event and the subsequent STOP event.

The array regs is declared with IOMMU_NREGS (3) elements and accessed
using IOMMU_CTRL (0) and IOMMU_BASE (8). In most cases, those values
are right shifted before being used as an index which results in indices
0 and 1. In one case, this right shift was missing for IOMMU_BASE which
results in an out-of-bounds write access with index 8.
The patch adds the missing shift operation also for IOMMU_CTRL where
it is needed only for cosmetic reasons.

In KVM trap & emulate (T&E) mode the flash reset region at 0xbfc00000
isn't executable, which is why the minimal kernel bootloader is loaded
and executed from the last 1MB of DRAM instead.
Therefore if no kernel is provided on the command line and KVM is
enabled, exit with an error since booting from flash will fail.

If the flash device is configured with a device-width which is
not equal to the bank-width, indicating that it is actually several
narrow flash devices in parallel, the CFI table should report the
number of blocks and the size of a single device, not of the whole
combined setup. This stops Linux from complaining:
"NOR chip too large to fit in mapping. Attempting to cope..."
As usual, we retain the old broken but backwards compatible behaviour
when the device-width is not specified.
