I threw in some ad-crock #ifdef to get past that one, and hit
another one, same basic issue but include/linux/pm.h this time:

  CC      drivers/base/power/sysfs.o
drivers/base/power/sysfs.c: In function 'wakeup_count_show':
drivers/base/power/sysfs.c:152: error: 'struct dev_pm_info' has no member named 'wakeup_count'
make[3]: *** [drivers/base/power/sysfs.o] Error 1
