[Qemu-devel] [PATCH 5/8 v4] s390-cpu: ipi_states enhancements |
Date: |

From: "Jason J. Herne" <address@hidden>
Modify s390_cpu_addr2state to allow fetching state information for cpu addresses
above smp_cpus. Hotplug requires this capability.
Also add s390_cpu_set_state function to allow modification of ipi_state entries
during hotplug.
