I left it there intentionally. First one because there is description in that comment which references noMMU. If this should be removed the whole comment should be tuned to make sense. It is better to do it in separate patch.
And second part. I know I removed that Kconfig macros for it but maybe good to talk about what needs to change to support different page size for systems with MMU.
Thanks, Michal
