H A D | mmio-mod.c | 3a5ff1f6 Thu Feb 10 16:49:00 CST 2022 Yury Norov <yury.norov@gmail.com> x86: Replace cpumask_weight() with cpumask_empty() where appropriate
In some cases, x86 code calls cpumask_weight() to check if any bit of a given cpumask is set.
This can be done more efficiently with cpumask_empty() because cpumask_empty() stops traversing the cpumask as soon as it finds first set bit, while cpumask_weight() counts all bits unconditionally.
