[PATCH 00/25] perf tools: minor improvements to Intel PT related stuff

[Adrian Hunter <adrian.hunter@intel.com>]

Hi

Here are some minor improvements to Intel PT related stuff.

First 3 patches are minor fixes:

      perf auxtrace: Fix 'instructions' period of zero
      perf report: Fix sample type validation for synthesized callchains
      perf intel-pt: Fix potential loop forever

Next 4 are minor improvements:

      perf intel-pt: Make logging slightly more efficient
      perf script: Allow time to be displayed in nanoseconds
      perf tools: Warn when AUX data has been lost
      perf tools: Add more documentation to export-to-postgresql.py script

Next 7 add support for branch stacks:

      perf auxtrace: Add option to synthesize branch stacks on samples
      perf report: Adjust sample type validation for synthesized branch stacks
      perf report: Also do default setup for synthesized branch stacks
      perf report: Skip events with null branch stacks
      perf inject: Set branch stack feature flag when synthesizing branch stacks
      perf intel-pt: Move branch filter logic
      perf intel-pt: Support generating branch stack

Next 6 allow for arbitrary-sized call stacks:

      perf report: Make max_stack value allow for synthesized callchains
      perf hists: Allow for max_stack greater than PERF_MAX_STACK_DEPTH
      perf callchain: Allow for max_stack greater than PERF_MAX_STACK_DEPTH
      perf script: Add a setting for maximum stack depth
      perf scripting python: Allow for max_stack greater than PERF_MAX_STACK_DEPTH
      perf script: Make scripting_max_stack value allow for synthesized callchains

Final 5 let Intel PT be used with autofdo:

      perf tools: Add perf_evlist__id2evsel_strict()
      perf tools: Add perf_evlist__del()
      perf inject: Remove more aux-related stuff when processing instruction traces
      perf inject: Add --strip option to strip out non-synthesized events
      perf intel-pt: Add mispred-all config option to aid use with autofdo
