Merge branch 'tracing/core' into tracing/hw-breakpoints

Conflicts:
	arch/Kconfig
	kernel/trace/trace.h

Merge reason: resolve the conflicts, plus adopt to the new
              ring-buffer APIs.

- * The original linux ioctl numbering scheme was just a general
- * "anything goes" setup, where more or less random numbers were
- * assigned.  Sorry, I was clueless when I started out on this.
- *
- * On the alpha, we'll try to clean it up a bit, using a more sane
- * ioctl numbering, and also trying to be compatible with OSF/1 in
- * the process. I'd like to clean it up for the i386 as well, but
- * it's so painful recognizing both the new and the old numbers..
- *
- * The same applies for for the MIPS ABI; in fact even the macros
- * from Linux/Alpha fit almost perfectly.
