From fdd33961e983dd5b1983c54ef39d243c88a4bffc Mon Sep 17 00:00:00 2001 From: Al Viro Date: Thu, 26 Jul 2007 17:35:39 +0100 Subject: [PATCH] amd64: fix get_user() on bitwise We really need force-cast when converting to final result type; unsigned long can be silently converted to integer types and to pointers, but not to bitwise.
