Subject: [PATCH 0/7] perf: cs-etm: Fixes around timestamped and timeless decoding

The first commit contains a fix for a recently introduced regression,
but was always a shortcoming in the Coresight code anyway.

The following commits are a tidyup in preparation for the last commit,
which is a fairly major change to the decode logic that's also
indirectly related to the regression so I thought it would be good time
to fix that now.

Applies to perf/core (9be6ab181b7b)

James Clark (7):
  perf: cs-etm: Fix timeless decode mode detection
  perf tools: Add util function for overriding user set config values
  perf: cs-etm: Don't test full_auxtrace because it's always set
  perf: cs-etm: Validate options after applying them
  perf: cs-etm: Allow user to override timestamp and contextid settings
  perf: cs-etm: Use bool type for boolean values
  perf: cs-etm: Add separate decode paths for timeless and per-thread
    modes
