Peter Anvin <hpa@xxxxxxxxx> CommitDate: Wed, 10 Feb 2010 12:03:34 -0800 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@xxxxxxx> LKML-Reference: <1265831716-7668-1-git-send-email-jslaby@xxxxxxx> Cc: Ingo Molnar <mingo@xxxxxxx> Cc: Thomas Gleixner <tglx@xxxxxxxxxxxxx> Cc: Ollie Wild <aaw@xxxxxxxxxx> Cc: x86@xxxxxxxxxx Cc: <stable@xxxxxxxxxx> Signed-off-by: H.
