+         the amount of time spent in hypervisor callsr.  Wall time spent in
+         each call is always calculated, and if available CPU cycles spent
+         are also calculated.  A directory named hcall_inst is added at the
+         root of the debugfs filesystem.  Within the hcall_inst directory
+         are files that contain CPU specific call statistics.

+         This option will add a small amount of overhead to all hypervisor
