From 02c0cd2dcf7fdc47d054b855b148ea8b82dbb7eb Mon Sep 17 00:00:00 2001 From: Len Brown Date: Fri, 17 Jun 2016 01:22:50 -0400 Subject: x86/tsc_msr: Remove irqoff around MSR-based TSC enumeration Remove the irqoff/irqon around MSR-based TSC enumeration, as it is not necessary. Also rename: try_msr_calibrate_tsc() to cpu_khz_from_msr(), as that better describes what the routine does.
