Yes. Or better I don't want to change the lowlevel blockdevice internals
so I give to such code always regular pages to eat.

No idea about rawio (I have not yet read the rawio code).
For debuggers I'll add a kmap to access_one_page in ptrace.c, thanks.

Yes it is. But only if such code can deal with anonymous or shm or
vmalloced pages.
