Detailed Description

A physical page of memory.

The kernel pre-allocates one of these for every physical page of memory in the system. This ensures that pages can be tracked correctly, and prevents circular dependencies between the page frame allocator and the kernel heap. As a consequence, this structure must be kept as small as possible.
