them unsigned I made the possible overflows hard to detect, and it only saved 1 bit which isn't principal, even less now that the underlying issue with the total of virtual memory has been fixed. (For the record, it will overflow with >=2T of VM total, with 32-bit ints used to keep counters in pages.) - While here, fix printing of other "struct vmtotal" members such as t_rq, t_dw, t_pw, and t_sw as they are also signed.
