Calling pause_all_vcpus()/resume_all_vcpus() from a VCPU thread might not be the best idea. As pause_all_vcpus() temporarily drops the qemu mutex, two parallel calls to pause_all_vcpus() can be active at a time, resulting in a deadlock. (either by two VCPUs or by the main thread and a VCPU) Let's handle it via the main loop instead, as suggested by Paolo. If we would have two parallel reset requests by two different VCPUs at the same time, the last one would win. We use the existing ipl device to handle it. The nice side effect is that we can get rid of reipl_requested. This change implies that all reset handling now goes via the common path, so "no-reboot" handling is now active for all kinds of reboots. Let's execute any CPU initialization code on the target CPU using run_on_cpu.
