Now that the MSU is using scatterlist, we can support multipage blocks. At the moment, the code assumes that all blocks are page-sized, but in larger buffers it may make sense to chunk together larger blocks of memory. One place where one-to-many relationship needs to be handled is the MSU buffer's mmap path. Get rid of the implicit assumption that all blocks are page-sized.
