For the fs/exfat/ build error: What is the target (x86_64, i386, arm64, arm, etc.)? What is the compiler and its version? That error usually means that the target is a 32-bit CPU and the code in question is doing an unsupported divide or modulus function. It possibly should be using a kernel macro from or other headers. -- ~Randy
