sys/dev/acpica acpi_cpu.c
Log:
Fix a shutdown hang on some SMP systems. The previous logic was to IPI all
CPUs to make sure idle threads are evicted from the softc before returning
from acpi_cpu_shutdown(). However, this is unnecessary since stop_cpus()
handles this for itself and at this point it's possible that our IPI will be
blocked (interrupts disabled).
