From: David S. Miller Date: Wed, 11 Apr 2007 05:10:39 +0000 (-0700) Subject: [S390]: Fix build on 31-bit. X-Git-Tag: v2.6.22-rc1~1128^2~120 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=cb8c181f288a1157bc717cc7a02412d4d1dc19bc;p=linux-2.6 [S390]: Fix build on 31-bit. Allow s390 to properly override the generic __div64_32() implementation by: 1) Using obj-y for div64.o in s390's makefile instead of lib-y 2) Adding the weak attribute to the generic implementation.
