Subject: [RFC PATCH v4 0/2] trace,smp: Add tracepoints for csd

Changes since RFCv3:
- Split the patch in 2: entry/exit and queue
- Fix 'struct __call_single_data' & call_single_data_t alignment issue
- Made all TP_printk follow the same pattern

Changes since RFCv2:
- Fixed some spacing issues and trace calls

Changes since RFCv1:
- Implemented trace_csd_queue_cpu() as suggested by Valentin Schneider
- Using EVENT_CLASS in order to avoid duplication
- Introduced new helper: csd_do_func()
- Name change from smp_call_function_* to csd_function_*
- Rebased on top of torvalds/master

Leonardo Bras (2):
  trace,smp: Add tracepoints around remotelly called functions
  trace,smp: Add tracepoints for scheduling remotelly called functions
