Public bug reported:
The opcode stressor generates a random mix of opcodes that can sometimes
generate code that trashes the stress-ng shared memory region that
contains stress-ng state across processes/threads. This results in
weird results in the progress bogo ops/counters being trashed. Fix this
by unmapping this region in the opcode stressor child process.
** Affects: stress-ng (Ubuntu)
