swapon creates a table using 1 B for each page in the swap. Therefore when a huge swap (e.g. 500 GB) is created, swapon fails with ENOMEM, because it is using vmalloc that allocates a contiguos memory. Thus we need to limit the maximum size of swap partitions. Sice we don't know the strict limit, let's use 128 GB that seems to work and should be enough for everybody.
