From: Hayden Goodfellow <Hayden.Goodfellow@xxxxxxx> [Why] Currently, the 32bit linux build is failing due to an issue with using the built-in / operator with a 64bit dividend. Doing so generates code which calls __udivdi3() in libgcc. However, libgcc is not linked with the kernel at this point in the build, hence this causes the 32bit build to fail to compile. [How] Change the / operator to div_u64 instead.
