From 4e6d03059d809ab08dd75c19203ccbdd94a58273 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 10 Feb 2010 20:55:16 +0100 Subject: [PATCH] x86, ia32_aout: do not kill argument mapping commit 318f6b228ba88a394ef560efc1bfe028ad5ae6b6 upstream. Do not set current->mm->mmap to NULL in 32-bit emulation on 64-bit load_aout_binary after flush_old_exec as it would destroy already set brpm mapping with arguments. Introduced by b6a2fea39318e43fee84fa7b0b90d68bed92d2ba mm: variable length argument support where the argument mapping in bprm was added. [ hpa: this is a regression from 2.6.22... time to kill a.out? ] Signed-off-by: Jiri Slaby LKML-Reference: <1265831716-7668-1-git-send-email-jslaby@suse.cz> Cc: Ingo Molnar Cc: Thomas Gleixner Cc: Ollie Wild Cc: x86@kernel.org Signed-off-by: H.
