[yocto] [KERNEL][PATCH] add utrace feature

[tom.zanussi at intel.com]

From: Tom Zanussi <tom.zanussi at intel.com>

This adds a utrace feature, in support of userspace tracing for systemtap.

It's been tested on actual x86 and x86-64 hardware, as well as qemux86-64
and qemuppc (utrace doesn't currently have support for arm or mips).

A couple examples with output have been added to the systemtap entry in
the tracing and profiling section of the Yocto wiki:

https://wiki.yoctoproject.org/wiki/Tracing_and_Profiling#systemtap

Please pull into the meta branch of linux-yocto.
