Subject[PATCH v2 0/5] padata flushing and CPU hotplug fixes
Date
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
