From 21d6d52a1b7028e6a6840bd82e354aefa9a5e203 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Tue, 14 Apr 2015 21:08:35 +0000 Subject: hrtimer: Get rid of softirq time The softirq time field in the clock bases is an optimization from the early days of hrtimers. It provides a coarse "jiffies" like time mostly for self rearming timers. But that comes with a price: - Larger code size - Extra storage space - Duplicated functions with really small differences The benefit of this is optimization is marginal for contemporary systems. Consolidate everything on the high resolution timer implementation. This makes further optimizations possible.
