As m68k doesn't support SMP or preempt yet, the spinlock calls tend to get optimized away, but not for all configurations, causing in some rare cases: | ERROR: "rtc_lock" [drivers/rtc/rtc-cmos.ko] undefined! | ERROR: "rtc_lock" [drivers/char/nvram.ko] undefined! Add the spinlock to the Atari core code to avoid this. Signed-off-by: Geert Uytterhoeven Acked-by: Michael Schmitz Signed-off-by: Linus Torvalds [*P)x
