Commit 4752c369 aka
"maps4: simplify interdependence of maps and smaps" broke /proc/pid/smaps,
causing it to display some vmas twice and other vmas not at all.  For example:

    grep .- /proc/1/smaps >/tmp/smaps; diff /proc/1/maps /tmp/smaps

    1  25d24
    2  < 7fd7e23aa000-7fd7e23ac000 rw-p 7fd7e23aa000 00:00 0
    3  28a28
    4  > ffffffffff600000-ffffffffff601000 r-xp 00000000 00:00 0  [vsyscall]

The bug has something to do with setting m->version before all the
seq_printf's have been performed.  show_map was doing this correctly,
but show_smap was doing this in the middle of its seq_printf sequence.
This patch arranges things so that the setting of m->version in show_smap
is also done at the end of its seq_printf sequence.

Testing: in addition to the above grep test, for each process I summed
up the 'Rss' fields of /proc/pid/smaps and compared that to the 'VmRSS'
field of /proc/pid/status.  All matched except for Xorg (which has a
/dev/mem mapping which Rss accounts for but VmRSS does not).  This result
gives us some confidence that neither /proc/pid/maps nor /proc/pid/smaps
are any longer skipping or double-counting vmas.

Commit f06febc9 ("timers: fix itimer/
many thread hang") introduced a new task_cputime interface and
subsequently only converted binfmt_elf over to it.  This results in the
build for binfmt_elf_fdpic blowing up given that p->signal->{u,s}time
have disappeared from underneath us.

Apply the same trivial fix from binfmt_elf to binfmt_elf_fdpic.

We're trying to keep the !CONFIG_SHMEM tiny-shmem.c (using ramfs without
swap) in synch with CONFIG_SHMEM shmem.c (and mpm is preparing patches
to combine them).  I was glad to see EXPORT_SYMBOL_GPL(shmem_file_setup)
go into shmem.c, but why not support DRM-GEM when !CONFIG_SHMEM too?
But caution says still depend on MMU, since !CONFIG_MMU is.. different.

This gets rid of an annoying warning in ehci-hcd.c when DEBUG isn't
enabled:

    warning: label 'err_debug' defined but not used

by moving it inside the already-existing #ifdef DEBUG, so that it
matches the goto.  And now my regular build is warning-free again.

Yes, this will probably be switched over to a cleaner model anyway, but
in the meantime I don't want to see the 'unused variable' warnings that
come from the disgusting #ifdef code.  Make the special case be a nice
inlien function of its own, clean up the code, and make the warning go
away.

I wish people didn't write code that gets (valid) warnings from the
compiler, but I'll limit my fixes to code that I actually care about (in
this case just because I see the warning and it annoys me).
