| |
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.
