target-arm queue: nothing hugely exciting here, the
bulk is Andrew's virt-acpi-build refactorings.
thanks

Some I2C devices will NAK if they have no data, so allow them to do this. This required the following changes: Go through all the event handlers and change them to return int and return 0. Modify i2c_start_transfer to terminate the transaction on a NAK. Modify smbus handing to not assert if a NAK occurs on a second operation, and terminate the transaction and return -1 instead. Add some information on semantics to I2CSlaveClass.

Now we have MachineState and the subclass VirtMachineState to do this. Fold the VirtBoardInfo into VirtMachineState rather than having some flags in one struct and some in another with no useful way to get between them. In the process we drop the code for looking up the memory map and irq map from the CPU model, because in practice we always use the same maps in all cases. For easier code review, this change removes the VirtBoardInfo type but leaves all the variables which used to be VirtBoardInfo* and are now VirtMachineState* with their now-confusing 'vbi' names.

We were incorrectly describing them in the device tree as edge triggered. This can cause problems for guest kernels in 4.8 before rc6: * pre-4.8 kernels ignore the values in the DT * 4.8 before rc6 write the DT values to the GIC config registers * newer than rc6 ignore the DT and insist that the timer interrupts are level triggered regardless Fix the DT so we're describing reality. For backwards-compatibility purposes, only do this for the virt-2.9 machine onward.
