Subject: [PATCH 0/2] [GIT PULL][v3.1] kprobes: can cause perf to crash the system


Ingo,

I tested and verified that the commends that Masami has shown will
crash the system. These patches do fix the problem.

I also verified that the same commands will crash 2.6.39 and have included
stable in the Cc of the commits.
