Spectre V2 & Meltdown Linux Fixes Might Get Disabled For Atom N270 & Other In-Order CPUs
There's a suggestion/proposal to disable the Spectre Variant Two and Meltdown mitigation by default with the Linux kernel for in-order CPUs.
If you have an old netbook still in use or the other once popular devices powered by the Intel Atom N270 or other in-order processors, there may be some reprieve when upgrading kernels in the future to get the Spectre/Meltdown mitigation disabled by default since these CPUs aren't vulnerable to attack but having the mitigation in place can be costly performance-wise.
