#     powerpc/xmon: Fix disabling tracing while in xmon
#     
#     Commit ed49f7fd6438d ("powerpc/xmon: Disable tracing when entering
#     xmon") added code to disable recording trace entries while in xmon. 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.
#
