Alan Cox	377a50503d	MFamd64 ... Simplify the sf_buf implementation. In short, make it a veneer over the direct virtual-to-physical mapping.	2004-04-18 08:10:04 +00:00
Alan Cox	e45db9b837	- Modify alpha's sf_buf implementation to use the direct virtual-to- ... physical mapping. - Move the sf_buf API to its own header file; make struct sf_buf's definition machine dependent. In this commit, we remove an unnecessary field from struct sf_buf on the alpha, amd64, and ia64. Ultimately, we may eliminate struct sf_buf on those architecures except as an opaque pointer that references a vm page.	2003-11-16 06:11:26 +00:00
