But powerpc is subtle and I foresee that we have to kill __devinitconst
and friends soonish.
The problem is that despite data being const the compiler does not
always mark the section const.
So we will see a lot of the errors you see for powerpc now
that we unconditionally specify a section.

Previously this inconsistentcy were hidden by the fact that powerpc tagets
seldom were build without CONFIG_HOTPLUG=y.

So the patches are correct.
Tomorrow I hope to do a patch that kill __devinitconst :-(
