Composite mul/div, shl/div and mul/shr operations on unsigned long integers.
On i386 architectures, these are implemented in assembler with intermediate results on 64 bits, using native 32-bit multiply and divide operations of the processor. Resulting implementation is hopefully more appropriate than general long-long arithmetics functions coming with gcc, which would not be available anycase inside the kernel (their use would require linking the gcc long-long module within a kernel module).
