rcutorture's module parameters currently use permissions of 0, so they don't show up in /sys/module/rcutorture/parameters. Change the permissions on all module parameters to world-readable (0444).
Signed-off-by: Josh Triplett <[EMAIL PROTECTED]> --- rcutorture does all of its initialization and thread startup when loaded, and relies on the parameters not changing during execution, so they should not permit writing.
