From 8224ca195874525533665bbcd23b6da1e575aa4d Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Fri, 27 Apr 2007 14:21:47 +0200 Subject: [PATCH] [AVR32] Fix compile error with gcc 4.1 gcc 4.1 doesn't seem to like const variables as inline assembly outputs. Drop support for reading 64-bit values using get_user() so that we can use an unsigned long to hold the result regardless of the actual size. This should be safe since many architectures, including i386, doesn't support reading 64-bit values with get_user().
