From: Ishizaki Kou Date: Thu, 13 Dec 2007 10:13:14 +0000 (+1100) Subject: [POWERPC] celleb: Split machine definition X-Git-Tag: v2.6.25-rc1~1131^2~266 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7e1961ff4954d6ab627d9b606785afdcd0dda84b;p=linux-2.6 [POWERPC] celleb: Split machine definition This splits the machine definition for celleb into two definitions, one for celleb_beat, and the other for celleb_native. Though this looks complex because of sorting some functions, there are no more semantic changes than that for the splitting.
