title: Page size on iOS ARM64 returned by host_statistics64
body: <p>Right now, I use the data returned from <code>host_statistics64</code> and multiplying page counts by 4K to get the amount of memory in bytes. However, any call to get the system page size that I can think of returns 16K pages. Is there a call that will return the page size used by <code>host_statistics64</code>? Or is the page size fixed at 4K for that call?</p>
