#     Merge branch 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace
#     
#     Pull execve updates from Eric Biederman:
#      "Last cycle for the Nth time I ran into bugs and quality of
#       implementation issues related to exec that could not be easily be
#       fixed because of the way exec is implemented. So I have been digging
#       into exec and cleanup up what I can.
#     
#       I don't think I have exec sorted out enough to fix the issues I
#       started with but I have made some headway this cycle with 4 sets of
#       changes.
#     
#        - promised cleanups after introducing exec_update_mutex
#     
#        - trivial cleanups for exec
#     
#        - control flow simplifications
#     
#        - remove the recomputation of bprm->cred
#     
#       The net result is code that is a bit easier to understand and work
#       with and a decrease in the number of lines of code (if you don't count
#       the added tests)"
#     
#     * 'exec-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (24 commits)
#       exec: Compute file based creds only once
#       exec: Add a per bprm->file version of per_clear
#       binfmt_elf_fdpic: fix execfd build regression
#       selftests/exec: Add binfmt_script regression test
#       exec: Remove recursion from search_binary_handler
#       exec: Generic execfd support
#       exec/binfmt_script: Don't modify bprm->buf and then return -ENOEXEC
#       exec: Move the call of prepare_binprm into search_binary_handler
#       exec: Allow load_misc_binary to call prepare_binprm unconditionally
#       exec: Convert security_bprm_set_creds into security_bprm_repopulate_creds
#       exec: Factor security_bprm_creds_for_exec out of security_bprm_set_creds
#       exec: Teach prepare_exec_creds how exec treats uids & gids
#       exec: Set the point of no return sooner
#       exec: Move handling of the point of no return to the top level
#       exec: Run sync_mm_rss before taking exec_update_mutex
#       exec: Fix spelling of search_binary_handler in a comment
#       exec: Move the comment from above de_thread to above unshare_sighand
#       exec: Rename flush_old_exec begin_new_exec
#       exec: Move most of setup_new_exec into flush_old_exec
