  perf/x86/intel/pt: Fix sampling using single range output (2022-11-16 10:12:59 +0100)

----------------------------------------------------------------
- Fix an intel PT erratum where CPUs do not support single range output
for more than 4K

- Fix a NULL ptr dereference which can happen after an NMI interferes
with the event enabling dance in amd_pmu_enable_all()

- Free the events array too when freeing uncore contexts on CPU online,
  thereby fixing a memory leak

- Improve the pending SIGTRAP check
