kernel/softirq.c: In function ‘tasklet_action’:
kernel/softirq.c:533:24: error: ‘a’ undeclared (first use in this function)
  tasklet_action_common(a, this_cpu_ptr(&tasklet_vec), TASKLET_SOFTIRQ);

Reverting https://github.com/copperhead/linux-hardened/commit/4c2a7c166bad4fc98973cd71a91ee7229f0968b8 fixes this.

EDIT: It seems fixed for 4.16 after recent changes but still occurs for 4.17. Closing for now.
