2017-08-30python: Make GlobalExitEvent.getCode() return an intAndreas Sandberg
PyBind normally casts integers returned from the C to long in Python. This is normally fine since long in most cases behaves just like an int. However, when passing the return value from getcode() to sys.exit, unexpected behavior ensues. Due to the way the function is defined, any type other than int (with the exception of None) will be treated as an error and be equivalent to sys.exit(1). Since we frequently use the sys.exit(event.getCode()) pattern, we need to ensure that the function returns an integer. This change adds an explicit type conversion to a Python integer in the wrapper code.

2017-08-01cpu, kvm: Fix deadlock issue when resuming a drained systemAndreas Sandberg
The KVM CPU sometimes needs to access devices when drain() is called. This typically happens on ARM when synchronizing devices that use the system register interface. When called from drain(), the event queue isn't locked since drain is called from the outside when the simulator isn't servicing any events. In such cases, performing a migration to the device's queue will unlock a mutex that isn't locked. This typically results in a deadlock when resuming the system since the lock will be in an undefined state.
