I'm working on adding disconnect/reselect logic to the sbic driver, and I
need to poke a few (5-10) bytes into some random part of physical memory
to clean up partial transfers. What's the preferred method of converting
from a physical address to something the CPU can use to poke at memory
with? I have some ideas, but I prefer not to create and then destroy a
mapping just to store a half-dozen bytes. And I don't want to start
fooling around with the CPU's registers either.
