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

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.
