[PATCH 3/7] perf tools: Set event->header.misc to PERF_RECORD_MISC_GUEST_USER if machine is guest.

From: Dongsheng Yang
Date: Fri Dec 20 2013 - 02:55:52 EST


When we synthesize the mmap events of user space, if machine is guest, we should
set the event->header.misc to PERF_RECORD_MISC_GUEST_USER, rather than
PERF_RECORD_MISC_USER.
