commit a93864955e4781ba05e76c95851c6c1d08be80d5 Author: Jan Beulich <jbeulich@xxxxxxxx> AuthorDate: Fri Dec 2 10:39:22 2022 +0100 Commit: Jan Beulich <jbeulich@xxxxxxxx> CommitDate: Fri Dec 2 10:39:22 2022 +0100 x86/APIC: make a few interrupt handler functions static Four of them are used in apic.c only and hence better wouldn't be exposed to other CUs. To avoid the need for forward declarations, move apic_intr_init() past the four handlers.
