Subject: [PATCH 15/15] linux/syscalls.h: add missing __user annotations
From: Arnd Bergmann <arnd@...db.de>
A couple of declarations in linux/syscalls.h are missing __user
annotations on their pointers, which can lead to warnings from
sparse because these don't match the implementation that have
the correct address space annotations.
