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
