Add #include <linux/cache.h> to define __read_mostly.
Convert cache.h to use uapi/linux/kernel.h instead
of linux/kernel.h to avoid recursive #includes.
Convert the ALIGN macro to __ALIGN_KERNEL.
printk_once only sets the bool variable tested
once so mark it __read_mostly.
Neaten the alignment so it matches the rest of the
pr_<level>_once #defines too.
