__div64_const32(): improve the generic C version Let's rework that code to avoid large immediate values and convert some 64-bit variables to 32-bit ones when possible. This allows gcc to produce smaller and better code. This even produces optimal code on RISC-V. Signed-off-by: Nicolas Pitre <nico@fluxnic.net> Signed-off-by: Arnd Bergmann <arnd@arndb.de>
