	   Adds support to dynamically detect the presence of the SVPBMT

	   ISA-extension (Supervisor-mode: page-based memory types) and

	   enable its usage.



	   The memory type for a page contains a combination of attributes

	   that indicate the cacheability, idempotency, and ordering

	   properties for access to that page.



	   The SVPBMT extension is only available on 64Bit cpus.
