OK, I'll bite. I glanced at a couple of drivers and don't see anything
explicit preventing them from being paged. Unless there is some voodoo
inthe build system that keeps these things resident, I'd say we have a
nontrivial problem on our hands.
If this problem is indeed un-adressed at the moment, I'd say we need a
tool to set the sections up as not paged, discardable, etc. At the
least, we need something that un-pages the whole driver. If we have to
do runtime paging control with Mm apis until we get compiler/linker
support, that's not the end of the world.
