From: Paul Mackerras Date: Wed, 19 Oct 2005 11:44:51 +0000 (+1000) Subject: ppc: Minor smp changes for consistency with ppc64 X-Git-Tag: v2.6.15-rc1~59^2~153 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7ed476d17f04473f70d796cb6c172bdcfcc9b8e5;p=linux-2.6 ppc: Minor smp changes for consistency with ppc64 This makes platform code use the smp_ops variable directly instead of ppc_md.smp_ops, removes the two unused `data' and `wait' arguments from the *_message_pass() functions, and removes the call to the never-implemented smp_ops->space_timers() function.
