Hello,

this patch series adds kfence support for s390, and was mainly
developed by Sven Schnelle. Given that he is currently busy I send
this out for him, since I'd like to get an ACK for the second patch,
which touches kfence common code.

This was already discussed here:
https://lore.kernel.org/lkml/CANpmjNPAS5kDsADb-DwvdFR9nRnX47-mFuEG2vmMPn5U3i3sGQ@mail.gmail.com/

With that ACK I'd like to carry the series via the s390 tree, so it
gets upstream during the next merge window. Hopefully that's ok.

Thanks,
Heiko
