Subject: [PATCH 05/16] tools lib traceevent: Add page_size field to pevent

From: Namhyung Kim <namhyung.kim@....com>

The page size of traced system can be different than current system's
because the recorded data file might be analyzed in a different machine.
In this case we should use original page size of traced system when
accessing the data file, so this information needs to be saved.
