As a result, amd_ibs_init() returns -EINVAL if IBS event is created with exclude_guest set. With the introduction of mediated PMU support, software-based handling of exclude_guest is permitted for PMUs that have the PERF_PMU_CAP_MEDIATED_VPMU capability. Since ibs_op and ibs_fetch pmus has PERF_PMU_CAP_MEDIATED_VPMU capability set, update perf_ibs_init() to remove exclude_guest check.
