In edk2, the division and shifting of 64-bit values are forbidden with C-language operators, because the compiler may generate intrinsic calls for them. For example, clang-3.8 emits a call to "__umoddi3" for UDF_LOGICAL_SECTOR_SIZE % Media->BlockSize in PartitionInstallUdfChildHandles(), if PartitionDxe is built for IA32, which then fails to link. UDF_LOGICAL_SECTOR_SIZE has type UINT64, while EFI_BLOCK_IO_MEDIA.BlockSize has type UINT32(). Replace the % operator with a DivU64x32Remainder() call.
