Hi,

All variants of pt_test:
  https://github.com/linux-test-project/ltp/blob/master/testcases/kernel/tracing/pt_test/pt_test.c
started failing after:
  38bb8d77d0b9 ("perf/x86/intel/pt: Split ToPA metadata and page layout")

with following error on console/dmesg:
  pt: ToPA ERROR encountered, trying to recover

on Broadwell-EP:

cpu family      : 6
model           : 79
model name      : Intel(R) Xeon(R) CPU E5-2699 v4 @ 2.20GHz
stepping        : 1
