[PATCH 5/5] misc: add clocksource-based entropy generation driver

2011-06-13 Thread Jarod Wilson
This is a fairly simple driver that just starts up a kernel thread that periodically calls the active clocksource's entropy-gathering function, if it has one. The default interval of 100us between polls doesn't show any measurable impact to cpu usage on a core 2 duo test rig here, and ensures the e
