Subject: Deprecate SA_xxx interrupt flags -V2
From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>
The deprecation of the SA_xxx interrupt flags did not emit deprecated
warnings. Andrew said about the removal of the deprecated flag defines:
> This is going to break a lot of external stuff. We should have found
> a way to make usage of SA_* emit deprecated warnings (or _some_
> warning) to warn people of impending doom. But I can't immediately
> find a way of doing that. if we _can_ find a way of doing this, I
> suspect we'll need to do it, and give people another six months. It's
> going to get ugly out there. We shall see...
Define the deprecated flags as a call to a __deprecated inline function
so a warning is emitted on compile time.
Extend the reprieve of out of tree drivers to 9/2007.
