If anyone has any objections, please let me know. ------------------ From: Adrian Hunter commit 692d0e63324d2954a0c63a812a8588e97023a295 upstream. 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". Signed-off-by: Adrian Hunter Cc: Andi Kleen Cc: David S.
