considering these functions were made weak only because of
probe_kernel_(read|write), then perhaps it makes more sense to move
the work there. it would mean that all consumers of these functions
work properly instead of just kgdb.
probe_kernel_write is already weak ... we just need to add weak to
probe_kernel_read i think, and make the functions available via a
"default" symbol so that arch overrides can tail back into the common
code when it makes sense.
