Working around Intel Hardware Flaws

Efforts to work around serious hardware flaws in Intel chips are ongoing. Nadav Amit posted a patch to improve compatibility mode with respect to Intel's Meltdown flaw. Compatibility mode is when the system emulates an older CPU in order to provide a runtime environment that supports an older piece of software that relies on the features of that CPU. The thing to be avoided is to emulate massive security holes created by hardware flaws in that older chip as well.

diff -u: Intel Design Flaw Fallout

For weeks, the world's been talking about severe Intel design flaws affecting many CPUs and forcing operating systems to look for sometimes costly workarounds. Linux patches for these issues are in a state of ongoing development. Security is always the first priority, at the expense of any other feature. Next would probably be the general speed of a running system for the average user. After that, the developers might begin piecing together any features that had been pulled as part of the initial security fix.
