Ok, here is the version of the fix I'll use for now: commit c3abb3b8d41814ce4691cc4cc3998b0f5242c8d0 Author: David S. Miller <[EMAIL PROTECTED]> Date: Tue Apr 10 22:10:39 2007 -0700 [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.
