Imported from linux's own git, at v3.7:include/uapi/linux/perf_event.h
(blob SHA-1 is 4f63c05d27c91d04569971ea4a2c4849203c36a9).
We cannot rely on the file being shipped by distributions. Older
versions did not have all fields in the perf_event_attr structure. If
those bits are enabled at runtime, the kernel will simply reject the
perf_open call (-EINVAL). Currently, this can only happen with the
non-default options exclude_guest and exclude_host.
