The installcheck testsuite triggers several apparently kprobes-related messages.

- Have you verified that the kernel has Masami's fix for bz9965 and my kretprobe
locking imbalance fixes?
- Is this problem only with x86(-32)?

Oops! Current upstream tree has the gs enablement patch in pt_regs, but doesn't
have Masami's fix for gs in kprobes. That's possibly the reason.
Hopefully fee039a1d0 (-tip) will be merged in Ingo's next push.

Indeed, this must cause reported problem, because the stack address will be moved
one entry. This means that any attempt to access to local variable from kretprobes
may refer to another variable.
