I notice a very similar patch has been applied to -current as r225076.

For the archives, I've done some testing with this patch on a Sun V890
with 64GB RAM and two 64GB swap partitions.  Prior to this patch, each
swap partition was truncated to 32GB.  With this patch, I have 128GB
swap.  I've tried filling the swap space to over 80GB and I am not
seeing any corruption (allocate lots of memory and fill with a known
pseudo-random pattern and then verify).
