From 0e5ac3a8b100469ea154f87dd57b685fbdd356f6 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 16 Jul 2014 21:05:18 +0000 Subject: [PATCH] timekeeping: Use tk_read_base as argument for timekeeping_get_ns() All the function needs is in the tk_read_base struct. No functional change for the current code, just a preparatory patch for the NMI safe accessor to clock monotonic which will use struct tk_read_base as well.
