Pull kconfig fixes for tiny setups from Josh Triplett:
"Two Kconfig bugfixes for 3.17 related to tinification. These fixes
make the Kconfig "General Setup" menu much more usable"
* tag 'tiny/kconfig-for-3.17' of https://git.kernel.org/pub/scm/linux/kernel/git/josh/linux:
init/Kconfig: Fix HAVE_FUTEX_CMPXCHG to not break up the EXPERT menu
init/Kconfig: Hide printk log config if CONFIG_PRINTK=n
commit 03b8c7b623 ("futex: Allow
architectures to skip futex_atomic_cmpxchg_inatomic() test") added the
HAVE_FUTEX_CMPXCHG symbol right below FUTEX. This placed it right in
the middle of the options for the EXPERT menu. However,
HAVE_FUTEX_CMPXCHG does not depend on EXPERT or FUTEX, so Kconfig stops
placing items in the EXPERT menu, and displays the remaining several
EXPERT items (starting with EPOLL) directly in the General Setup menu.
Since both users of HAVE_FUTEX_CMPXCHG only select it "if FUTEX", make
HAVE_FUTEX_CMPXCHG itself depend on FUTEX. With this change, the
subsequent items display as part of the EXPERT menu again; the EMBEDDED
menu now appears as the next top-level item in the General Setup menu,
which makes General Setup much shorter and more usable.

Pull trace ring buffer iterator fix from Steven Rostedt:
"While testing some new changes for 3.18, I kept hitting a bug every so
often in the ring buffer. At first I thought it had to do with some
of the changes I was working on, but then testing something else I
realized that the bug was in 3.17 itself. I ran several bisects as
the bug was not very reproducible, and finally came up with the commit
that I could reproduce easily within a few minutes, and without the
change I could run the tests over an hour without issue. The change
fit the bug and I figured out a fix. That bad commit was:
Commit 651e22f270 "ring-buffer: Always reset iterator to reader page"
This commit fixed a bug, but in the process created another one. It
used the wrong value as the cached value that is used to see if things
changed while an iterator was in use. This made it look like a change
always happened, and could cause the iterator to go into an infinite
loop"

The uas driver uses the block layer tag for USB3 stream IDs. With
blk-mq we can get larger tag numbers that the queue depth, which breaks
this assumption. A fix is under way for 3.18, but sits on top of
large changes so can't easily be backported. Set the disable_blk_mq
path so that a uas device can't easily crash the system when using
blk-mq for SCSI.

"These are three regression fixes (cpufreq core, pcc-cpufreq, i915 /

cpufreq integrator driver.
Specifics:
- A recent cpufreq core fix went too far and introduced a regression
in the system suspend code path. Fix from Viresh Kumar.
- An ACPI-related commit in the i915 driver that fixed backlight
problems for some Thinkpads inadvertently broke a Dell machine (in
3.16). Fix from Aaron Lu.
- The pcc-cpufreq driver was broken during the 3.15 cycle by a commit
that put wait_event() under a spinlock by mistake. Fix that
(Rafael J Wysocki).

i2cdetect -q was broken (everything was a false positive, and no transfers were
actually being sent over i2c). The way it works is by sending a 0 length write
request and checking for NACK. This patch fixes the 0 length writes and actually
sends them.

Merge fixes from Andrew Morton:
"5 fixes"
* emailed patches from Andrew Morton <akpm@linux-foundation.org>:
mm: page_alloc: fix zone allocation fairness on UP
perf: fix perf bug in fork()
MAINTAINERS: change git URL for mpc5xxx tree
mm: memcontrol: do not iterate uninitialized memcgs
ocfs2/dlm: should put mle when goto kill in dlm_assert_master_handler
The zone allocation batches can easily underflow due to higher-order
allocations or spills to remote nodes. On SMP that's fine, because
underflows are expected from concurrency and dealt with by returning 0.
But on UP, zone_page_state will just return a wrapped unsigned long,
which will get past the <= 0 check and then consider the zone eligible
until its watermarks are hit.
Commit 3a025760fc ("mm: page_alloc: spill to remote nodes before
waking kswapd") already made the counter-resetting use
atomic_long_read() to accomodate underflows from remote spills, but it
didn't go all the way with it.
Make it clear that these batches are expected to go negative regardless
of concurrency, and use atomic_long_read() everywhere.
Fixes: 81c0a2bb51 ("mm: page_alloc: fair zone allocator policy")

Oleg noticed that a cleanup by Sylvain actually uncovered a bug; by
calling perf_event_free_task() when failing sched_fork() we will not yet
have done the memset() on ->perf_event_ctxp[] and will therefore try and
'free' the inherited contexts, which are still in use by the parent
process. This is bad..

The cgroup iterators yield css objects that have not yet gone through
css_online(), but they are not complete memcgs at this point and so the
memcg iterators should not return them. Commit d8ad305597 ("mm/memcg:
iteration skip memcgs not yet fully initialized") set out to implement
exactly this, but it uses CSS_ONLINE, a cgroup-internal flag that does
not meet the ordering requirements for memcg, and so the iterator may
skip over initialized groups, or return partially initialized memcgs.
The cgroup core can not reasonably provide a clear answer on whether the
object around the css has been fully initialized, as that depends on
controller-specific locking and lifetime rules. Thus, introduce a
memcg-specific flag that is set after the memcg has been initialized in
css_online(), and read before mem_cgroup_iter() callers access the memcg
members.
