[PATCH v4 0/9] record btrace: prepare for a new trace format

[Markus Metzger <markus dot t dot metzger at intel dot com>]

I had to change a few strings so instead of sending another delta update,
I send the entire series.

Changes to v3:

  - changed a few strings around the term Branch Trace Store
  - fixed an overflow bug when enabling branch tracing
  - removed unrelated bug-fix patches that were not in the original series

This is the first part of a patch series that adds support for a new trace
format.  The entire series consists of three parts:

  - preparation (this)
  - support live inferior tracing
  - support trace in core files


Besides preparing for an additional trace format, this first part adds the
following functionality:

  - allow the trace buffer size to be configured
  - indicate errors as gaps in the trace

Markus Metzger (9):
  btrace: add struct btrace_data
  btrace: add format argument to supports_btrace
  btrace, linux: add perf event buffer abstraction
  record btrace: add configuration struct
  record-btrace: add bts buffer size configuration option
  btrace: update btrace_compute_ftrace parameters
  btrace: extend struct btrace_insn
  btrace: identify cpu
  record-btrace: indicate gaps
