I dunno. If we're going to put multiple values into the file now and
add to the ABI, can we be more explicit about it?
echo "physical_address=0x40000000 numa_node=3" > memory/probe
I'd *GREATLY* prefer that over this new syntax. The existing mechanism
is obtuse enough, and the ',3' makes it more so.
We should have the code around to parse arguments like that, too, since
we use it for the boot command-line.
