Subject: [PATCH] Deprecate SA_xxx interrupt flags -V2
Date: Fri, 06 Apr 2007 15:49:26 +0200	[thread overview]
Message-ID: <1175867366.28263.454.camel@localhost.localdomain> (raw)
In-Reply-To: <1169584278.21181.86.camel@localhost.localdomain>

The deprecation of the SA_xxx interrupt flags did not emit deprecated
warnings. Andrew said about the removal of the deprecated flag defines:

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.
