256d046ca7 update-linux-headers.sh: Pull in asm-generic/kvm_para.h
Add asm-generic/kvm_para.h to the set of non-architecture specific
KVM kernel headers we copy into QEMU. This header may be included
by an architecture's kvm_para.h header.

a9605e0317 kvmvapic: Disable if there is insufficient memory
We need at least 1M of RAM to map the option ROM. Otherwise, we will
corrupt host memory or even crash:

    $ qemu-system-x86_64 -nodefaults --enable-kvm -vnc :0 -m 640k

050a46065d kvm: i8254: Finish time conversion fix
0cdd3d1444 fixed reading back the counter load time from the kernel
while assuming the kernel would always update its load time on writing
the state. That is only true for channel 1, and so pit_get_channel_info
returned wrong output pin states for high counter values.

Fix this by applying the offset also on kvm_pit_put. Now we also need to
update the offset when we write the state while the VM is stopped as it
keeps on changing in that state.

205df4d1a8 kvm: i8254: Cache kernel clock offset in KVMPITState
To prepare the final fix for clock calibration issues with the in-kernel
PIT, we want to cache the offset between vmclock and the clock used by
the in-kernel PIT. So far, we only need to update it when the VM state
changes between running and stopped because we only read the in-kernel
PIT state while the VM is running.

3a1363acf9 linux-user: ARM: Ignore immediate value for svc in thumb mode
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.

or -B is used into 'init_guest_space' and then call 'init_guest_space'

25df49f6eb qmp: add SUSPEND_DISK event
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

17c8660b0b qmp: emit the WAKEUP event when the guest is put to run
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.

1405819637 qmp: don't emit the RESET event on wakeup from S3
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.
