Building arm:allmodconfig ... failed
Building i386:allyesconfig ... failed
Building i386:allmodconfig ... failed

ERROR: "__aeabi_uldivmod" [fs/f2fs/f2fs.ko] undefined!
ERROR: "__aeabi_ldivmod" [drivers/rtc/rtc-mt6397.ko] undefined!
make[1]: *** [__modpost] Error 1

This is the error message seen when building arm:allmodconfig;
i386 has the same problem but the message is a bit different.

Looks like there are some new 64-bit divide operations.
