[Qemu-devel] [PATCH v2 06/12] cpus: check cpu->running in cpu_get_icount_raw()

["Alex Bennée" <alex.bennee@linaro.org>]

The lifetime of current_cpu is now the lifetime of the vCPU thread.
However get_icount_raw() can apply a fudge factor if called while code
is running to take into account the current executed instruction
count.

To ensure this is always the case we also check cpu->running.
