Especially since reverting it will break a whole bunch of cell blades,
which wouldn't be nice (those cannot do PIO and have that controller).
In the meantime, we might "workaround" with a hack to only enable MMIO
on those cell
blades, something like:
#ifdef CONFIG_PPC64
if (machine_is(cell))
mmio = 1;
#endif
That might get us out of the regression until we find the proper
solution ?
Cheers,
Ben.
