    Proposed fix to security flaw


      In wake of the massive Intel security flaw many OSes will now leave the kernel spaces out of the TLB which will result in 30%-50% performance hit.  OUCH!!!


      Intel should design a new CPU arch where one core is dedicated to kernel and others are user apps.  Then create an inter-core interrupt or something (SMP extension).  These kernel only core(s) could have reduced instruction sets or something.  Maybe 2 kernel cores, 4 user cores, etc.  If unsupported OS runs on CPU then the kernel cores are just unseen.


      Just an idea...
