The direct mapped area occupies L0 slots from 256 to 265 included (i.e. 10 slots), resulting in 5TB (512GB * 10) of virtual address space. However, due to incorrect slot subtraction (we take 9 slots into account) we set DIRECTMAP_SIZE to 4.5TB instead. Fix it.Note that we only support up to 2TB of physical memory so this is a latent issue.
