pseries SPLPAR machines are able to retrieve a log of dispatch and
preempt events from the hypervisor. With this information, we can
see when and why each dispatch & preempt is occuring.
This change adds a set of debugfs files allowing userspace to read this
dispatch log.
Based on initial patches from Nishanth Aravamudan <nacc@us.ibm.com>.
