Subject: [PATCH v4 0/2] cpuhp enhancements

This series combines the two uses thus far identified for cpuhp in
random.c. v3 uses prepare instead of teardown. v4 guards the added
function with CONFIG_SMP, since it's not used on !CONFIG_SMP.

Jason A. Donenfeld (2):
  random: set fast pool count to zero in cpuhp prepare
  random: invalidate crngs and batches in cpuhp prepare
