We don't particularly need it for the nommu case, it's just using the default PAGE_SIZE case there. The primary reason for having it defined is so we can use the same cache alias checking and d-cache purging code on parts that can operate with or without the MMU enabled.
So it would be nice to have the variable generally accessible regardless of CONFIG_MMU setting, rather than having to have a private definition for the nommu case.
