de-hole some structs on amd64

Hi, I tested removing some slop (i.e. structure packing/de-holing) on amd64, this went through a full kernel + userland build. struct proc 20 bytes (6 places) --> 4 bytes (2 places) struct process 28 bytes (6 places) --> 4 bytes (1 place) struct vm_map 8 bytes (2 places) --> 0 bytes Thanks d
