Subject: monitor: Use qemu_get_cpu() in monitor_set_cpu()
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=1c8bb3cc7b98ad07a028567b86fc6baa5c5a0b7a;p=qmiga%2Fqemu.git

monitor: Use qemu_get_cpu() in monitor_set_cpu()

No functional change, just a reduction of CPU loops.

The mon_cpu field is left untouched for now since changing that requires
a number of larger prerequisites, including cpu_synchronize_state() and
mon_get_cpu().
