Expose tmem "freeable" memory for use by management tools. Management tools looking for a machine with available memory often look at free_memory to determine if there is enough physical memory to house a new or migrating guest. Since tmem absorbs much or all free memory, and since "ephemeral" tmem memory can be synchronously freed, management tools need more data -- not only how much memory is "free" but also how much memory is "freeable" by tmem if tmem is told (via an already existing tmem hypercall) to relinquish freeable memory. This patch provides that extra piece of data (in MB). Signed-off-by: Dan Magenheimer <dan.magenheimer@oracle.com>
