[PATCH] i386: Fix fake return address
The fake return address was being set to __KERNEL_PDA, rather than 0. Push it earlier while %eax still equals 0. Signed-off-by: Jeremy Fitzhardinge <jeremy@xensource.com> Signed-off-by: Andi Kleen <ak@suse.de> Cc: Andi Kleen <ak@muc.de> Cc: Andrew Morton <akpm@osdl.org>
