Subject: [PATCH 09/75] perf script: Use fallbacks for branch stacks
From: Adrian Hunter <adrian.hunter@...el.com>
Branch stacks do not necessarily have the same cpumode as the 'ip'. Use
the fallback functions in those cases.
This patch depends on patch "perf tools: Add fallback functions for cases
where cpumode is insufficient".
