From 7f9f303aa33c7acc7b4aa9ebea25cbd990bc707b Mon Sep 17 00:00:00 2001 From: Jim Cromie Date: Mon, 26 Jun 2006 00:25:15 -0700 Subject: [PATCH] generic-time: add macro to simplify/hide mask constants Add a CLOCKSOURCE_MASK macro to simplify initializing the mask for a struct clocksource, and use it to replace literal mask constants in the various clocksource drivers.
