From de02797aa744c96a90f47be7bc081ce2f74b17fd Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Wed, 1 Feb 2006 03:06:02 -0800 Subject: [PATCH] [PATCH] sh: Cleanup struct sh_cpuinfo for clock framework changes Now that the clock framework changes have been integrated, the manual clock accounting that was done in sh_cpuinfo can be dropped. Also correct a bug with running past the end of the CPU flags when there's a mismatch between the added flags and printed ones.
