      Fix a deadlock case in the CPU hotplug flow · b12a4efb
      由 Jose Ricardo Ziviani 提交于 
      We need to set cs->halted to 1 before calling ppc_set_compat. The reason
is that ppc_set_compat kicks up the new thread created to manage the
hotplugged KVM virtual CPU and the code drives directly to KVM_RUN
ioctl. When cs->halted is 1, the code:

int kvm_cpu_exec(CPUState *cpu)
...
     if (kvm_arch_process_async_events(cpu)) {
         atomic_set(&cpu->exit_request, 0);
         return EXCP_HLT;
     }
...

returns before it reaches KVM_RUN, giving time to the main thread to
finish its job. Otherwise we can fall in a deadlock because the KVM
thread will issue the KVM_RUN ioctl while the main thread is setting up
KVM registers. Depending on how these jobs are scheduled we'll end up
freezing QEMU.

The following output shows kvm_vcpu_ioctl sleeping because it cannot get
the mutex and never will.
PS: kvm_vcpu_ioctl was triggered kvm_set_one_reg - compat_pvr.
