Subject: m68k: correct setting of struct user.u_ar0
From: Geert Uytterhoeven <[EMAIL PROTECTED]>
Commit 6e16d89bcd668a95eb22add24c02d80890232b66
Sanitize the type of struct user.u_ar0
struct user.u_ar0 is defined to contain a pointer offset on all
architectures in which it is defined (all architectures which define an
a.out format except SPARC.) However, it has a pointer type in the headers,
which is pointless -- <asm/user.h> is not exported to userspace, and it
just makes the code messy.
Redefine the field as "unsigned long" (which is the same size as a pointer
on all Linux architectures) and change the setting code to user offsetof()
instead of hand-coded arithmetic.
forgot to change the m68k setting code, causing the following compiler warning:
arch/m68k/kernel/process.c:338: warning: assignment makes integer from
pointer without a cast
