Maintain pre-zygote fork linear-alloc pages as shared-clean Userfaultfd tends to dirty all the pages of the space it is used on. However, we want to maintain the shared-clean trait of the pages allocated in zygote process prior to first fork. This CL separates the pre-zygote fork arenas from the userfaultfd visited ones, thereby reataining the former's shared-clean trait.
