Gaah. I guess it's the VM_IOREMAP case that is the cause of all this horridness.
So we'd have to know not to mess with IO mappings. Annoying.
But I think my patch could still act as a starting point, except that
case KCORE_VMALLOC:
would have to have some kind of "if this is not a regular vmalloc,
just skip it" logic.
So I guess we can't remove all those lines, but we *could* replace all
the vread_iter() code with a "bool can_I_vread_this()" instead. So the
fallback would still be to just do the bounce buffer copy.
Or something.
Oh well.
Linus
