[PATCH 0/9] perf intel-pt: Add support for synthesizing branch stacks for regular events

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

Hi

This patchset adds Intel PT support for synthesizing branch stacks for
regular events.  This follows on from the patchset that did the same thing
for call chains.

The first 3 patches convert Intel PT to using thread-stack to record branch
stacks, which allows branch stacks to be accumulated separately for each
thread.

The next 3 patches add support for synthesizing branch stacks for regular
events.

The final 2 patches update some documentation.
