m68k does not support SMP. The access to the rtc is already serialized with local_irq_save/restore which is sufficient on UP. The open() protection in arch/m68k/mvme16x/rtc.c is not pretty but sufficient on UP and safe w/o the BKL. open() in arch/m68k/bvme6000/rtc.c can do with the same atomic logic as arch/m68k/mvme16x/rtc.c Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Geert Uytterhoeven <geert@linux-m68k.org> |
