I have Linux host running as a kvm hypervisor. It's running CentOS. (So the
kernel is based on 3.10 but with loads of stuff backported by RedHat.) I
realize this is not a mainline kernel, but I was wondering if anyone is aware of
similar issues that had been fixed in mainline.

Hey, dunno if you're looking for commit
6dec97dc929 ("mm: move_ptes -- Set soft dirty bit depending on pte type")

CONFIG_MEM_SOFT_DIRTY doesn't exist in our kernel so I don't think this is the issue. Thanks for the suggestion though.
