Do we really need to do that patching right now to add base 4460 support?

If we're just doing a bunch of renames all over the place to add support
for a new processor variant, something is wrong. This is exactly the kind
of "crazy churn" Linus was complaining about. In this case the crazy churn
is "let's rename 4430 to 44XX all over the place".

To me it's sane to assume that we can have most of 4430 features on 4460
and don't need to rename 4430 to 44XX for that. Adding 4460 should be
just add few new 4460 defines, then do an arch_initcall to fixup things
between 4430 and 4460.

It would be nice to get the base 4460 support merged as the patches look
ready to go otherwise. Rajendra, I suggest you take a quick look and see
if you can leave out the dependency to the 4430 to 44XX rename patch to
add minimal 4460 support. Then we can patch in the missing features later
on, most likely we don't even need the arch_initcall fixup initially either.

This would also leave out the dependency between the various patch
series which will always lead into issues with merging code. Changes to
the infrastructure issues like this should have been patched away early.
The merge window is about to start and we're still waiting for the
dependencies to get sorted out.

Regards,

Tony
