This patch fixes the problem during checkpoing where the mempool is not restored, but using only the one specified in the config file as a new execution. In order to fix that this changes modifyies the serialize/unserialize functions for mempools and create new funcionts on se_workload to make sure mempools ends up in the m5.cpt. We change as well the unserialize mempool function to update according the checkpoint file so the execution starts with the same free pages and free pointers.
