Patch #1 replaces the needlessly complex routine to determine the number of translation levels and the size and alignment of the root table based on the T0SZ setting.
Patch #2 fixes the fix for allocating page aligned pages, which is a truism and as such does not require any special care to begin with. Patch #3 switches to a suitably aligned pool allocation for the root table if its size is much smaller than a page. Patch #4 makes the size of the VA space in the VM registers equal to the GCD memory map size.
