From 3cc698789a3f44dabc5eed389b6c123caf787c0f Mon Sep 17 00:00:00 2001 From: Paul Mackerras Date: Tue, 28 Oct 2008 00:18:11 +0000 Subject: powerpc: Eliminate unused do_gtod variable Since we started using the generic timekeeping code, we haven't had a powerpc-specific version of do_gettimeofday, and hence there is now nothing that reads the do_gtod variable in arch/powerpc/kernel/time.c. This therefore removes it and the code that sets it.
