src/sys/dev/acpi: acpi_cpu.c acpi_cpu.h acpi_cpu_cstate.c
Log Message:
Remove the recently added ACPICPU_FLAG_INIT and instead operate with the
existing ACPICPU_FLAG_C, as was intended. Set that flag only after the
idle-loop has been installed, so that the notify handler errors out if an
interrupt is received before the idle-loop is in place.
