In the future mm->exe_file will be done without mmap_sem serialization, thus isolate and reorganize the tile elf code to make the transition easier. Good users will, make use of the more standard get_mm_exe_file(), requiring only holding the mmap_sem to read the value, and relying on reference counting to make sure that the exe file won't dissappear underneath us. The visible effects of this patch are: o We now take and drop the mmap_sem more often. Instead of just in arch_setup_additional_pages(), we also do it in: 1) get_mm_exe_file() 2) to get the mm->vm_file and notify the simulator. [Note that 1) will disappear once we change the locking rules for exe_file.] o We avoid getting a free page and doing d_path() while holding the mmap_sem. This requires reordering the checks.
