From 7bc7d637452383d56ba4368d4336b0dde1bb476d Mon Sep 17 00:00:00 2001 From: john stultz Date: Fri, 2 Oct 2009 16:24:15 -0700 Subject: time: Remove xtime_cache With the prior logarithmic time accumulation patch, xtime will now always be within one "tick" of the current time, instead of possibly half a second off. This removes the need for the xtime_cache value, which always stored the time at the last interrupt, so this patch cleans that up removing the xtime_cache related code. This is a bit simpler, but still could use some wider testing.
