page_bitmaps does not need to be volatile since it is going to be treated as atomic. In fact, as long as each variable is treated as atomic, we do not need volatile at all, as that means it is modified by outside means, aka hardware, etc. The atomic macros already ensure optimizations that could cause incorrect values to be used do not happen. Finally, the first loop is redundant as they are iterated over again in the loop below.
