From c79f76777d678ba454aa727800e1386a1fd1f2e8 Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 20 Feb 2006 22:56:01 -0800 Subject: [SPARC64]: Args to SUNW,set-trap-table are 64-bit. They were getting truncated to 32-bit and this is very bad when your MMU fault status area is in physical memory above 4GB on SUN4V. Signed-off-by: David S.
