Bypass kernel heap for storing PageInfo.
...
Since these are stored in arrays that are typically 512 KiB each
(i.e. which in turn typically store metadata for 128 MiB), they will
certainly be a page-size multiple, and large contiguous allocations are
allowed at least at boot time. Not only is the linked-list allocator
less efficient for that, but this change will also help reduce TLB
overhead.
