From 7b28b0d000eeb62d77add636f5d6eb0da04e48aa Mon Sep 17 00:00:00 2001 From: Sean Hefty Date: Tue, 1 Nov 2005 13:18:54 -0800 Subject: [IB] ucm: 32/64 compatibility fixes Fix structure layouts to ensure same size on 32-bit and 64-bit architectures. This permits 32-bit userspace apps on a 64-bit kernel.
