8578b891ec Revert "perf tools: Fix jump label always changing during tracing" 
This reverts commit deaff8b659.

This commit makes CLOEXEC feature undetected for normal users,
because per-cpu events are priviledged.

9b0d2d875d perf tools: Expose 'addr' functions so they can be reused 
Move some functions and functionality related to the use of
'addr' out of builtin-script so they can be reused.

The moved functions are: is_bts_event() and sample_addr_correlates_sym()
and a new function perf_event__preprocess_sample_addr() is created from
bits of print_sample_addr().

perf_event__preprocess_sample_addr() is the equivalent of
perf_event__preprocess_sample() but for 'addr' instead of 'ip'.

hardware which doesn't know about linux threads.

deaff8b659 perf tools: Fix jump label always changing during tracing 
Intel PT decoding walks the object code to reconstruct the trace.  A
jump label change during tracing causes decoding errors.

The "Enable close-on-exec flag on perf file descriptor" patch caused
there to be always a jump label change.

It was found that using a per-cpu context instead of a per-thread
context for the probe of the close-on-exec feature, made the problem go
away.
