commit 130fa5bc81b44b6cc1fbdea3abf6db0da22964e0 upstream
applies to 3.14-stable, 3.13-stable, 3.10-stable
The crypto algorithm modules utilizing the crypto daemon could
be used early when the system start up. Using module_init
does not guarantee that the daemon's work queue is initialized
when the cypto alorithm depending on crypto_wq starts. It is necessary
to initialize the crypto work queue earlier at the subsystem
init time to make sure that it is initialized
when used.
