From c60185248fd1c7b777f08d3f3337836331da3d17 Mon Sep 17 00:00:00 2001 From: john stultz Date: Wed, 23 Dec 2009 04:14:03 +0000 Subject: parisc: Convert to read/update_persistent_clock This patch converts the parisc architecture to use the generic read_persistent_clock and update_persistent_clock interfaces, reducing the amount of arch specific code we have to maintain, and allowing for further cleanups in the future. I have not built or tested this patch, so help from arch maintainers would be appreciated.
