Jordan Niethe 62e3d4210a powerpc/bpf: Write protect JIT code ... Add the necessary call to bpf_jit_binary_lock_ro() to remove write and add exec permissions to the JIT image after it has finished being written. Without CONFIG_STRICT_MODULE_RWX the image will be writable and executable until the call to bpf_jit_binary_lock_ro().
