3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: "H. Peter Anvin" <[email protected]> commit 5189fa19a4b2b4c3bec37c3a019d446148827717 upstream. There is only one error code to return for a bad user-space buffer pointer passed to a system call in the same address space as the system call is executed, and that is EFAULT. Furthermore, the low-level access routines, which catch most of the faults, return EFAULT already. Signed-off-by: H.
