Ok, so I just upgraded to 3.10.0 (gentoo system) and made a nice big
64GiB swap volume on lvm as usual.
Suddenly, swapon doesn't recognize more than 32GiB, as top lists only
that much swap space.
swapon using *two* separate 32GiB partitions works fine, but for some
reason a swap partition bigger than 32GiB isn't fully recognized.
Previous kernel versions IIRC recognized the entire swap partition.
Is something wrong or is this new behavior standard?

Hold on a minute, I just found out something ate my kernel config and
turned off PAE when I upgraded.
This in turn shrunk my pte's from 64 bits to 32 bits and is probably
what killed >32G swap extents.
