From 655e52d2b62458032fc67ff7daaa664af6f36fb5 Mon Sep 17 00:00:00 2001 From: Prarit Bhargava Date: Mon, 19 Sep 2016 08:51:40 -0400 Subject: [PATCH] x86/tsc: Use cpu id defines instead of hex constants asm/intel-family.h contains defines for cpu ids which should be used instead of hex constants. Convert the switch case in native_calibrate_tsc() to use the defines before adding more cpu models.
