This set addresses exe_file use for users that require the mmap_sem for other things (mostly looking up the related vma->vm_file). In a lot of cases we end up with scenarios where we take the mmap_sem in get_mm_exe_file(), just to then take it again soon after. This is only temporary as we will remove the need for mmap_sem when dealing with exe_file.
Applies on top of linux-next (-20150225). The arch bits are entirely 100% untested, so I apologize if there are any stupid build issues. Thanks!
