## Description

In the Linux kernel, the following vulnerability has been resolved:  padata: Always leave BHs disabled when running ->parallel()  A deadlock can happen when an overloaded system runs ->parallel() in the context of the current task:      padata_do_parallel       ->parallel()         pcrypt_aead_enc/dec           padata_do_serial             spin_lock(&reorder->lock) // BHs still enabled               <interrupt>                 ...                   __do_softirq                     ...                       padata_do_serial                         spin_lock(&reorder->lock)  It's a bug for BHs to be on in _do_serial as Steffen points out, so ensure they're off in the "current task" case like they are in padata_parallel_worker to avoid this situation.
