When running in thumb mode, Linux doesn't evaluate the immediate value
of the svc instruction, but instead just always assumes the syscall number
to be in r7.
This fixes executing go_bootstrap while building go for me.

Roll the code used to initialize the guest memory space when -R
or -B is used into 'init_guest_space' and then call 'init_guest_space'
from the driver. This way the reserved guest memory space can
be probed for. Calling 'mmap' just once as is currently done is not
guaranteed to succeed since the host address space validation might fail.

This command attempts to map to the behavior of -cpu ?. Unfortunately, the
output of this command differs wildly across targets.
To accommodate this, we use a weak symbol to implement a default version of the
command that fails with a QERR_NOT_SUPPORTED error code. Targets can then
override and implement this command if it makes sense for them.

Emitted when the guest makes a request to enter S4 state.
There are three possible ways of having this event, as described here:
http://lists.gnu.org/archive/html/qemu-devel/2012-07/msg02307.html
I've decided to add a new event and make it indepedent of SHUTDOWN.
This means that the SHUTDOWN event will eventually follow the
SUSPEND_DISK event.
I've choosen this way because of two reasons:
1. Having an indepedent event makes it possible to query for its
existence by using query-events
2. In the future, we may allow the user to change what QEMU should
do as a result of the guest entering S4. So it's a good idea to
keep both events separated
Signed-off-by: Luiz Capitulino <lcapitulino@redhat.com>
Today, the WAKEUP event is emitted when a wakeup _request_ is made.
This could be the system_wakeup command, for example.
A better semantic would be to emit the event when the guest is
already running, as that's what matters in the end. This commit does
that change.
In theory, this could break compatibility. In practice, it shouldn't
happen though, as clients shouldn't rely on timing characteristics of
the events. That is, a client relying that the guest is not running
when the event arrives may break if the event arrives after the guest
is already running.
This commit also adds the missing documentation for the WAKEUP event.

QEMU is basically using reset logic when waking up from S3. This
causes the QMP RESET event to be emitted, which is wrong. Also,
the runstate checks done in reset are not necessary for S3 wakeup.
Fix this by untangling wakeup from reset logic and passing
VMRESET_SILENT to qemu_system_reset() to avoid emitting the RESET
event.

both function receive a human message instead and the qobject is

Instead of returning something like:

qemu-ga now returns:

IMPORTANT: this BREAKS QMP's compatibility for the error response.
This commit changes QMP's wire protocol to make use of the simpler
error format introduced by previous commits.
There are two important (and mostly incompatible) changes:
1. Almost all error classes have been replaced by GenericError. The
only classes that are still supported for compatibility with
libvirt are: CommandNotFound, DeviceNotActive, KVMMissingCap,
DeviceNotFound and MigrationExpected
2. The 'data' field of the error dictionary is gone
As an example, an error response like:
{ "error": { "class": "DeviceNotRemovable",
"data": { "device": "virtio0" },
"desc": "Device 'virtio0' is not removable" } }
Will now be emitted as:
{ "error": { "class": "GenericError",
"desc": "Device 'virtio0' is not removable" } }

The new argument is added to functions qerror_report() and error_set().
It's stored in Error and QError. qerror_report_err() is also updated to

The QERR_ macros are changed to contain a place holder value for the
new argument, so that the value is used on all current calls to
qerror_report() and error_set() (and also to initialize qerror_table[]).
Next commit will update the QERR_ macros with a proper ErrorClass
