Fabricio Voznika 38de91b028 Add build guard to files using go:linkname
Funcion signatures are not validated during compilation. Since
they are not exported, they can change at any time. The guard
ensures that they are verified at least on every version upgrade.

Adin Scannell 1b5062263b Add allocator abstraction for page tables.
In order to prevent possible garbage collection and reuse of page table
pages prior to invalidation, introduce a former allocator abstraction
that can ensure entries are held during a single traversal. This also
cleans up the abstraction and splits it out of the machine itself.
