commit 64e87d4bd3201bf8a4685083ee4daf5c0d001452 upstream. domain_add_cpu() is called whenever a CPU is brought online. The earlier call to domain_setup_ctrlval() allocates the control value arrays. If domain_setup_mon_state() fails, the control value arrays are not freed. Add the missing kfree() calls.
