Hi all,

I would like to inform you about an issue uncovered in kernel 4.18,
coming from the L1TF mitigation patch set.

The PAE kernel (i586), when running on intal x86_64 hardware with an
address size of > 42 phusical bits can show issue while enabling swap
space, in the form of:

Truncating oversized swap area, only using 0k out of 2047996k (to be
found in dmesg)

The options you have in this case are:
* Accept to run without swap for the time being
* Keep on using a 4.17.x kernel
* If it's a VM you run a 32bit guest in on a 64bit host, you might tune
the address size of the machine

The kernel team has already submitted a fixed kernel into Tumbleweed,
which is currently being staged and is hopefully reaching Tumbleweed
soon.

Cheers,
Dominique
