Public Attributes
std::size_t	m_size
	Size (log_2) of the entire allocation represented by this superpage.
std::size_t	m_min_page_size
	The size of the smallest page in this superpage.
std::size_t	m_num_pages
	Total number of pages in this superpage.
std::unique_ptr< page_state[]>	m_pages
	Array of pages, remembering that this always resides in host-accessible memory.
unique_alloc_ptr< std::byte[]>	m_memory
	The actual allocation, which is just a byte pointer.

Detailed Description
