From 8cf14af0a740fb7e9f94a203b5a989beb875d58f Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Wed, 28 Sep 2005 20:21:11 -0700 Subject: [SPARC64]: Convert to use generic exception table support. The funny "range" exception table entries we had were only used by the compat layer socketcall assembly, and it wasn't even needed there. For free we now get proper exception table sorting and fast binary searching. Signed-off-by: David S.
