So it's OK to use the "...._to_cpup" macros with unaligned pointers?
I'm asking whether ...
1) Passing le64_to_cpup an unaligned pointer is "OK" and within the
intended use of the function. I'm having trouble finding whether
this is documented somewhere.
2) These new changes to the sparc64 unaligned access fault handling
will make it OK to leave the aoe driver the way it is in the
mainline kernel.
