(Adrian Hunter) - Fix segfault in intel PT, by making it follow the 'struct thread' lifetime cycle checking expectations, noticed for instance, when processing perf.data files with Intel PT data using 'perf script' and when exiting 'perf report' (Adrian Hunter) - Fix CFI usage from .eh_frame and .debug_frame, which sometimes requires that we fallback from .eh_frame to .debug_frame in architectures such as PowerPC (Hemant Kumar) Signed-off-by: Arnaldo Carvalho de Melo Signed-off-by: Ingo Molnar --- 9a969403c34ffcc4c92118616665ae1c7eb5a650
