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.
