Not sure who to blame for the commit, it was in the linux-next.patch and I'm
too lazy to pull down the git tree and dig it out.

  CC      kernel/power/main.o
kernel/power/main.c: In function 'wakeup_count_show':
kernel/power/main.c:241: error: implicit declaration of function 'pm_get_wakeup_count'
kernel/power/main.c: In function 'wakeup_count_store':
kernel/power/main.c:251: error: implicit declaration of function 'pm_save_wakeup_count'
make[2]: *** [kernel/power/main.o] Error 1

Problem is that declaration in include/linux/suspend.h is wrapped in
a #ifdef CONFIG_PM_SLEEP, but the usage in kernel/power/main.c isn't. So
it dies a horrid death if your config doesn't include PM_SLEEP.
