Alexey Dobriyan f22ef333c3 cpumask: make cpumask_next() out-of-line ... Every for_each_XXX_cpu() invocation calls cpumask_next() which is an inline function: static inline unsigned int cpumask_next(int n, const struct cpumask *srcp) { /* -1 is a legal arg here. */ if (n != -1) cpumask_check(n); return find_next_bit(cpumask_bits(srcp), nr_cpumask_bits, n + 1); } However! find_next_bit() is regular out-of-line function which means "nr_cpu_ids" load and increment happen at the caller resulting in a lot of bloat x86_64 defconfig: add/remove: 3/0 grow/shrink: 8/373 up/down: 155/-5668 (-5513) x86_64 allyesconfig-ish: add/remove: 3/1 grow/shrink: 57/634 up/down: 3515/-28177 (-24662) !!! Some archs redefine find_next_bit() but it is OK: m68k inline but SMP is not supported arm out-of-line unicore32 out-of-line Function call will happen anyway, so move load and increment into callee.
