Re: Perhaps they have moved on
See Intels pre-execution pipeline hack (Not bug, because they knew and picked good-enough).
Made its way into Intel chips, AMD, ARM and IBM chips. Just two makers of modem chips, both with onboard processors. Rather than correct the hardware, secret inefficient software semi-fixes are being chunked out. Only Linux people have fessed up into saying software remediation is slower than microcode hobbling). Rather than a fix, Intel is directing resources to encrypted code execution extensions that will make viruses undetectable..
