The 4.15 linux-kvm kernel is missing both the
CONFIG_SLAB_FREELIST_RANDOM and CONFIG_SLAB_FREELIST_HARDENED config
option (I've now added a check ot qrt to look for the latter as well).
Unless there's a reason for it, the linux-kvm config should follow the
regular kernel config here as well.
Thanks.
