The memory size variable was a 32-bit int. This meant that the size of the
memory was limited to 4GB. This patch changes the type of the variable to
64-bit to support larger memory sizes. Thanks to Raghuraman Balasubramanian
for bringing this to notice.
Fixes checkpointing with respect to lost events after swapping event queues.
Also adds DPRINTFs to better understand what's going on when Ruby serializes
and unserializes.
This patch adds functions to the memory vector class that can be used for
collating memory pages to raw trace and for populating pages from a raw
trace.
This was done with an automated process, so there could be things that were
done in this tree in the past that didn't make it. One known regression
is that atomic memory operations do not seem to work properly anymore.
