Subject: [PATCH 22/76] tools lib traceevent: Add page_size field to pevent

From: Namhyung Kim <[email protected]>

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.
