Re: div_u64/do_div stack size usage, was Re: [v3] block: Removed a warning while compiling with a cross compiler for parisc

Sorry for late respond, I was at work. The problem was solved for me too,
after setting the CONFIG_CC_OPTIMIZE_FOR_SIZE, and I have went through the
gcc 9.4 manual to look for the -f option for -O2, it seems that all -f option
that we would not specify is already excluded with -Os. changing defconfig, it
seems for me a good idea.
