From 130e6b25a28ff5b2421d6cae5f2bac1f5afdcfb0 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Thu, 18 Jul 2013 16:21:28 -0700 Subject: [PATCH] clocksource: sirf: Switch to sched_clock_register() and use 64 bits The 32 bit sched_clock interface now supports 64 bits. Upgrade to the 64 bit function to allow us to remove the 32 bit registration interface and use all 64 bits of this timer.
