From d28ede83791defee9a81e558540699dc46dbbe13 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 16 Jul 2014 21:05:16 +0000 Subject: timekeeping: Create struct tk_read_base and use it in struct timekeeper The members of the new struct are the required ones for the new NMI safe accessor to clcok monotonic. In order to reuse the existing timekeeping code and to make the update of the fast NMI safe timekeepers a simple memcpy use the struct for the timekeeper as well and convert all users.
