i386 allmodconfig:

lib/lib-syms.c:21: error: '__div64_32' undeclared here (not in a function)
lib/lib-syms.c:21: warning: type defaults to 'int' in declaration of '__div64_32'

I'll drop 

lib-allow-linker-to-eliminate-unused-functions.patch
lib-allow-linker-to-eliminate-unused-functions-fix.patch
lib-allow-linker-to-eliminate-unused-functions-fix-2.patch

for now and will return the patch for warranty repairs, please.

lib-allow-linker-to-eliminate-unused-functions-fix.patch is a
linux-next thing, so if you base the next version on mainline, please
remind me to resurrect
lib-allow-linker-to-eliminate-unused-functions-fix.patch.

I have travel coming up and won't be very functional until late next
week.
