+Subject: [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().
