perf probe: Search both .eh_frame and .debug_frame sections for probe
location (2016-02-02 13:30:16 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- tracepoint_error() can receive e=NULL, robustify it, fixes a problem noticed
with a very specific combination: Machine with Intel PT (e.g. Broadwell),
kernel with no perf_event_attr.context_switch feature (e.g. 4.2) and
unreadable
tracefs (for instance !root users), making the fallback from
perf_event_attr.context_switch to the sched:sched_switch tracepoint to fail
reading its info from tracefs, fix it. (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)
