Kajol Jain 9a69d0d24d fpga: dfl: fme: Fix cpu hotplug issue in performance reporting ... commit ec6446d5304b3c3dd692a1e244df7e40bbb5af36 upstream. The performance reporting driver added cpu hotplug feature but it didn't add pmu migration call in cpu offline function. This can create an issue incase the current designated cpu being used to collect fme pmu data got offline, as based on current code we are not migrating fme pmu to new target cpu. Because of that perf will still try to fetch data from that offline cpu and hence we will not get counter data. Patch fixed this issue by adding pmu_migrate_context call in fme_perf_offline_cpu function.
