------------------------------------------------------
Subject: sparc64/power.c: convert to use the kthread API
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
This starts the sparc64 powerd using kthread_run instead of kernel_thread
and daemonize. Making the code slightly simpler and more maintainable.
In addition the unnecessary flush_signals is removed.
