Good point - will do.

Yes - but a lot of other places that require patching will run
long time before (wof.S, wuf.S etc). At least I assume so.

My plan is to introduce a sparc_start_kernel() function
in setup_32.c which is called from head_32.S.

There I will do the initial stuff like patching and prom_init.
And then call the real start_kernel().

The final patchset will establish this before introducing
any users so I do not change when I patch in the middle
of the patch-set.

The current patch was to make sure I was on the right track,
hence the RFC.
