I'm having some problems getting high memory support to work smoothly in my driver. The documentation doesn't indicate what I might be doing wrong so I'll have to ask here. The problem seems to be that kmap & co maps a single page into kernel memory. So when I happen to cross page boundaries I start corrupting some unrelated parts of the kernel. I would prefer not having to consider page boundaries in an already messy PIO loop, so I've been trying to find either a routine to map an entire sg entry or some way to force the block layer to not give me stuff crossing pages. As you can guess I have not found anything that can do what I want, so some pointers would be nice.
