From 941e492bdb1239d2ca8f5736cdfd3ff83d00cb90 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 6 Feb 2008 01:36:42 -0800 Subject: read_current_timer() cleanups - All implementations can be __devinit - The function prototypes were in asm/timex.h but they all must be the same, so create a single declaration in linux/timex.h. - uninline the sparc64 version to match the other architectures - Don't bother #defining ARCH_HAS_READ_CURRENT_TIMER to a particular value.
