Subject: [PATCH 0/4] Branch stack improvements 

I came across a few generic non-Arm issues when reviewing Anshuman's new
support for branch record buffers on Arm [1].

The first one is a fix to an error message which is misleading if the
feature is unavailable and the remaining ones make the branch type field
visible in perf report and perf script so that it can be debugged or used
by other tools.

Applies to perf/core (56dce86819)

Thanks
James
