Comment 17 for bug 1304754

This is going to be true on AARCH64 also where most distros are going to be using 64k pages (some might use 4k pages if they also support AARCH32). MIPS has many different page sizes too (4k, 8k, 16k, 32k, and 64k). So hard coding the page size seems wrong, maybe you should call getpagesize instead.
