x86/apic: Get rid of "warning: 'acpi_ioapic_lock' defined but not used" kbuild test robot reported this against the -RT tree: |>> arch/x86/kernel/acpi/boot.c:90:21: warning: 'acpi_ioapic_lock' defined but not used [-Wunused-variable] | static DEFINE_MUTEX(acpi_ioapic_lock); | ^ | include/linux/mutex_rt.h:27:15: note: in definition of macro 'DEFINE_MUTEX' | struct mutex mutexname = __MUTEX_INITIALIZER(mutexname) ^~~~~~~~~ which is also true (as in non-used) for !RT but the compiler does not emit a warning.
