From 994c1553a158ada9db5ab64c9178a0d23c0a42ce Mon Sep 17 00:00:00 2001 From: Andrew Cooper <andrew.cooper3@citrix.com> Date: Wed, 29 Mar 2023 13:07:03 +0100 Subject: x86: Remove temporary {cpuid,msr}_policy defines With all code areas updated, drop the temporary defines and adjust all remaining users. No practical change.
