[PATCH v2 0/5] generic IPI tracing

[Nicolas Pitre]

This is v2 of the series initially posted here:

http://news.gmane.org/group/gmane.linux.kernel/thread=1750391

Steven / Ingo: Would you please merge those patches in your tree for some 
linux-next exposure and mainline inclusion? Patches 1 to 4 may go in now. 
I'm unsure about patch 5 so I'll leave it to your appreciation.

Changes since v1:

- added empty tracepoint_string when !CONFIG_TRACING, from Steven
- ipi_types[] is unconditionally marked with __tracepoint_string now
- added comment to arch/x86/kernel/smp.c justifying the #undef's
- collected ACKs, refined commit logs
