This is the bulk of the removal of sun4c support.
I have tried to be careful not to break the build
during the removal process.
I like the diffstat summary:
36 files changed, 75 insertions(+), 3726 deletions(-)
The final result is boot tested on my ss5 box.
I also boot tested a few of the steps.
So all-in-all I feel rather confident about this
patch-set.
Something noteworthy:
o In patch 1 I redo the nmi handler a bit.
I think what I did is OK - but here I would like
some extra carefull revieing please.
o In patch 12 I have removed all the sun + sun4c
support in head_32.S.
Here I did some minor restructuring.
I have not tested if the warnings works on a sun4c box,
as mine is hidden away right now.
This is not a complete removal - but I will address
the remaining items later.
The remaining bits are random cleanups + removal
of btfixup when no longer needed.
Patches are sent to the mailing list only (+ davem).
