From: Hollis Blanchard Date: Sat, 7 Aug 2010 17:33:58 +0000 (-0700) Subject: KVM: PPC: allow ppc440gp to pass the compatibility check X-Git-Tag: v2.6.37-rc1~142^2~85 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=ebc65874e9e8f3b8bbbc69aa49acd7489cd41c52;p=platform%2Fkernel%2Flinux-exynos.git KVM: PPC: allow ppc440gp to pass the compatibility check Match only the first part of cur_cpu_spec->platform. 440GP (the first 440 processor) is identified by the string "ppc440gp", while all later 440 processors use simply "ppc440".
