From: Paul Mackerras Date: Thu, 4 Oct 2007 01:02:09 +0000 (+1000) Subject: [PPC] Use cpu setup routines from cpu_setup_44x.S for ARCH=ppc X-Git-Tag: v2.6.24-rc1~1450^2~103 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=26f571d7c968dbd30656fc1421eeb0d9088aaad9;p=linux-2.6 [PPC] Use cpu setup routines from cpu_setup_44x.S for ARCH=ppc Commit 8112753bb2c0045398c89d0647792b39805f6d40 made 44x in ARCH=powerpc builds use cpu setup routines in cpu_setup_44x.S, but didn't make a similar change for ARCH=ppc, and consequently the ARCH=ppc builds fail with undefined symbols (since both use the same cputable.c). This fixes it by including cpu_setup_44x.S in the ARCH=ppc builds, and by taking out the now-redundant FPU initialization in arch/ppc/kernel/head_44x.S.
