Alan Cox 6031c68de4 The page flag PGA_WRITEABLE is set and cleared exclusively by the pmap ... layer, but it is read directly by the MI VM layer. This change introduces pmap_page_is_write_mapped() in order to completely encapsulate all direct access to PGA_WRITEABLE in the pmap layer. Aesthetics aside, I am making this change because amd64 will likely begin using an alternative method to track write mappings, and having pmap_page_is_write_mapped() in place allows me to make such a change without further modification to the MI VM layer. As an added bonus, tidy up some nearby comments concerning page flags. Reviewed by: kib MFC after: 6 weeks		2012-06-16 18:56:19 +00:00
