RE: [patch 1/2] powerpc: Sky CPU: redundant or incorrect tests on unsigned

We don't plan on carrying it forward, so I assume that ripping it out will
not affect us.
Anything new would be completely new development.

Hi !

Well, that isn't really the question :-) Is there any interest in
ensuring that your current Sky is supported by upstream linux kernels or
not ? As I said, the current kernel seems to contain code relative to
the Sky CPU that is never enabled and potentially has issue. Are you
guys interested in fixing this so that upstream linux supports your
existing products, or should we just rip the code out ?

Cheers,
Ben.

The sky cpu is a PPC7448.
I'm actually amazed that you guys are still working on a problem for
a
product that was finished a number of years ago, at the request of
someone
who hasn't worked here for years.
I sorry you, seem to have been wasting your time.
I think, but am NOT sure,  that our HAA function sets it off.

Still, we have finished the product some time ago, and as far as
reported
have no problems.
Again, I'm sorry you have wasted any time on this, we just recently
found
these emails.

Well, there seem to be some code in the Linux kernel related to that CPU
that is either dead or incomplete. So if you guys have no interest in
it, we might just rip it out completely.

Cheers,
Ben.
