From 592913ecb87a9e06f98ddb55b298f1a66bf94c6b Mon Sep 17 00:00:00 2001 From: John Stultz Date: Tue, 13 Jul 2010 17:56:20 -0700 Subject: time: Kill off CONFIG_GENERIC_TIME Now that all arches have been converted over to use generic time via clocksources or arch_gettimeoffset(), we can remove the GENERIC_TIME config option and simplify the generic code.

This allows it to avoid accessing xtime and wall_to_monotonic directly.
