Hi,
Here are some miscellaneous padata fixes, mostly to do with CPU hotplug.
This time around there's a new hotplug state to make the CPU remove path
cleaner, and the CC list grew a bit.

Daniel

v2:
 - patches 1-3 are new; 4-5 have changed since v1[*]
 - attempted to fix padata flushing as requested (Herbert)
 - changed hotplug state in which __padata_remove_cpu() is
   called (Herbert)
 - purged cpumask_clear_cpu() calls from same function (Herbert)
 - dropped v1's patch 3/2 (Herbert)
 - after more thought, left the Fixes: tag on the last patch the same

testing:
 - testcase was tcrypt mode=215 sec=1 throughout
 - ran all cpumask combos among parallel cpumasks, serial cpumasks, and CPU
   hotplug in a 3-CPU VM
 - lockdep to check patch 4
 - tested at each patch in this set with and without
   CONFIG_CRYPTO_PCRYPT

Series based on recent mainline plus all padata patches in cryptodev:

Daniel Jordan (5):
  padata: make flushing work with async users
  padata: remove reorder_objects
  padata: get rid of padata_remove_cpu() for real
  padata: always acquire cpu_hotplug_lock before pinst->lock
  padata: validate cpumask without removed CPU during offline
