x86, ia32_aout: do not kill argument mapping
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 <jslaby@suse.cz> LKML-Reference: <1265831716-7668-1-git-send-email-jslaby@suse.cz> Cc: Ingo Molnar <mingo@elte.hu> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ollie Wild <aaw@google.com> Cc: x86@kernel.org Cc: <stable@kernel.org> Signed-off-by: H.
