The # commit introduced a variable 'tracing_enabled' to record if tracing was # enabled on xmon entry, and used this to conditionally enable tracing # during exit from xmon. # # However, we are not checking the value of 'fromipi' variable in # xmon_core() when setting 'tracing_enabled'. Due to this, when secondary # cpus enter xmon, they will see tracing as being disabled already and # tracing won't be re-enabled on exit. Fix the same. # # Fixes: ed49f7fd6438d ("powerpc/xmon: Disable tracing when entering xmon") # Signed-off-by: Naveen N.
