From 97fa21f65c3eb5bbab9b4734bed37fd624cddd86 Mon Sep 17 00:00:00 2001 From: Borislav Petkov Date: Sun, 6 Nov 2022 22:24:08 +0100 Subject: x86/resctrl: Move MSR defines into msr-index.h msr-index.h should contain all MSRs for easier grepping for MSR numbers when dealing with unchecked MSR access warnings, for example. Move the resctrl ones. Prefix IA32_PQR_ASSOC with "MSR_" while at it. No functional changes.
