I do not see why Specter and Meltdown exploits are solely the fault of the CPU design. I suspect that these exploits on Intel64 systems could be mitigated by placing the "protected" information within a page, who's page table entry has the Page-level cache disable (PCD) flag set. This then becomes an O/S software related issue that would have minimal overhead impact.
