Subject: cpqphp: partially convert to use the kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
This patch changes cpqphp to use kthread_run and not kernel_thread and
daemonize to startup and setup the cpqphp thread.
akpm: needs to be converted to use kthread_should_stop() and kthread_stop()
too.
