This change sets the allocation orders for the different page sizes (4k, 16k, 64k) based on PAGE_SHIFT. Before this change, the orders for large page sizes were calculated incorrectly, this caused system heap to allocate from 2% to 4% more memory on 16KiB page size kernels.

This change was tested on 4k/16k page size kernels.
