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.
