Subject: [PATCH 0/2] perf/probe: verify instruction/offset in perf before
 adding a uprobe

This patch series is to augment Srikar's perf support for uprobes patch
(https://lkml.org/lkml/2012/4/11/191) with the following features:

a. Instruction verification for user space tracing
b. Function boundary validation support to uprobes as its kernel
counterpart (Commit-ID: 1c1bc922).

This will help in ensuring uprobe is placed at right location inside
the intended function.
