From 4ea1636b04dbd66536fa387bae2eea463efc705b Mon Sep 17 00:00:00 2001 From: Andy Lutomirski Date: Thu, 25 Jun 2015 18:44:07 +0200 Subject: x86/asm/tsc: Rename native_read_tsc() to rdtsc() Now that there is no paravirt TSC, the "native" is inappropriate. The function does RDTSC, so give it the obvious name: rdtsc().
