From 053080a9d1c8cf1950115ad92ce94242ebc5f25c Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Tue, 16 Feb 2016 09:43:22 +0100 Subject: [PATCH] x86/msr: Document msr-index.h rule for addition In order to keep this file's size sensible and not cause too much unnecessary churn, make the rule explicit - similar to pci_ids.h - that only MSRs which are used in multiple compilation units, should get added to it.
