The description of the memory.{stat,numa_stat} file has been updated to
clarify that the output values can be in bytes or pages.
This change ensures that users are aware that the unit of measurement for
memory values can vary and should be verified by consulting the memory.stat
It's known that
workingset_*, pg* are counted in pages
