trace, documentation: Fix branch profiling location in debugfs
David Rientjes [Thu, 17 Mar 2011 00:17:08 +0000 (17:17 -0700)]
The debugfs interface for branch profiling is through

/sys/kernel/debug/tracing/trace_stat/branch_annotated
/sys/kernel/debug/tracing/trace_stat/branch_all

so update the Kconfig accordingly.
