      Description

      We're currently using a fixed address space range for the mark stack space, both in terms of it's base address and it's size. This isn't really needed, we could just as well let os::reserve_memory() pick and address range for us and only reserve ZMarkStackSpaceLimit bytes, instead of 1TB.
