Hi,
For timekeeping I wrote a program which waits for interrupts on
gpio-pins and then tells the local ntp daemon the clock offset.
I'm aware of the pps support in recent kernel but that does not work
(yet) on all platforms (eg cubieboard 1).
This has worked for quite some time but no longer.
I found a strange spike in one of my machine's load average.
The machine does nothing (right now). The normal load average is nearly
zero, the user and system usage is not more than 5 per cent. But once in
a while the load average go to more than one, some times even much
higher (5-20).

Add APIs for software dummy event to track task/comm/mmap events
separately. The perf record will use them to save such events in a
separate mmap buffer to make it easy to index. This is a preparation of
multi-thread support which will come later.

When indexed data file support is enabled, a dummy tracking event will
be used to track metadata (like task, comm and mmap events) for a
session and actual samples will be recorded in separate (intermediate)
files and then merged (with index table).
Provide separate mmap to the dummy tracking

The perf_event_attr.task bit is to track task (fork and exit) events

The perf_evlist__mmap_track function creates data mmaps and optionally
tracking mmaps for events. It'll be used for perf record to save events
in a separate files and build an index table. Checking dummy tracking
event in perf_evlist__mmap() alone is not enough as users can specify a

This patch unifies the term called 'USB_OTG' and 'USB_HOST'
into USB_HOST. OTG(On-The-Go) function supports USB host and
this driver sents 'USB-Host event. So, unifies term to USB_HOST.
