4.20-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit 68b5e4326e4b8ac9080835005d8254fed0fb3c56 ]
Add the proper includes and make smca_get_name() static.
Fix an actual bug too which the warning triggered:
arch/x86/kernel/cpu/mcheck/therm_throt.c:395:39: error: conflicting \ types for ‘smp_thermal_interrupt’ asmlinkage __visible void __irq_entry smp_thermal_interrupt(struct pt_regs *r) ^~~~~~~~~~~~~~~~~~~~~ In file included from arch/x86/kernel/cpu/mcheck/therm_throt.c:29: ./arch/x86/include/asm/traps.h:107:17: note: previous declaration of \ ‘smp_thermal_interrupt’ was here asmlinkage void smp_thermal_interrupt(void);
