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? ]
