From 8a4b06d391b0a42a373808979b5028f5c84d9c6a Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Mon, 18 Feb 2019 22:51:43 +0100 Subject: x86/speculation/mds: Add sysfs reporting for MDS Add the sysfs reporting file for MDS. It exposes the vulnerability and mitigation state similar to the existing files for the other speculative hardware vulnerabilities.
