perf_event_open.2: Document PERF_RECORD_MISC_PROC_MAP_PARSE_TIMEOUT
...
Linux 4.2 reserved a new bit from the misc field in
the perf_event_open() mmap sample buffer:
PERF_RECORD_MISC_PROC_MAP_PARSE_TIMEOUT
Despite being reserved in the public
include/uapi/linux/perf_event.h header file, this bit is never set
by the kernel. Rather, it is used internally by the user-space
"perf" utility to indicate that, when attempting to parse all of
the /proc/xxx/maps files for the sample, it ended up taking too
long so the scan was aborted.
