No idea what exactly went wrong, but Yong ended up with a branch where the vm_size was always overwritten with the value 64. So we can completely drop this patch and yes when an user overrides the vm_size value he/she should know what the consequences are. Regards, Christian.

Only they depend on ATS, so only they need to be forced to be 48-bits. On the other hand, it could be argued that a user who manually sets the VM size with a module parameter knows what they're doing. So let them break ATS.
