+Subject: x86, ia32_aout: do not kill argument mapping
+
+From: Jiri Slaby <jslaby@suse.cz>
+
+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? ]
