* To calculate the alignment, we first take the largest of the freelist

* by the freelist entry size to determine the number of freelist entries
* required by the PM. Finally, as each entry holds a single PM physical
* page, we multiple the number of entries by the page size.
*
* As an example, if the base address alignment is 16 bytes, the SLC cache
* line size is 64 bytes and the freelist entry size is 4 bytes then 16
* entries are required, as we take the SLC cacheline size (being the larger
* of the two values) and divide this by 4. If the PM page size is 4096
