    Subject[PATCH 3.16 199/202] binfmt_elf: Fix missing SIGKILL for empty PIE
    3.16.66-rc1 review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Ben Hutchings <ben@decadent.org.uk>

    Commit ea08dc5191d9 "fs/binfmt_elf.c: fix bug in loading of PIE
    binaries", which was a backport of commit a87938b2e246 upstream,
    added a new failure path to load_elf_binary().

    Before commit 19d860a140be "handle suicide on late failure exits in
    execve() in search_binary_handler()", load_elf_binary() wass
    responsible for sending a fatal signal to the task in case of an error
    after flushing the old executable. Add that to the new failure path.
