2014-10-03init/Kconfig: Fix HAVE_FUTEX_CMPXCHG to not break up the EXPERT menuJosh Triplett
commit 03b8c7b623c80af264c4c8d6111e5c6289933666 ("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.

2014-10-03driver/base/node: remove unnecessary kfree of node struct from ↵Yasuaki Ishimatsu
unregister_one_node Commit 92d585ef067d ("numa: fix NULL pointer access and memory leak in unregister_one_node()") added kfree() of node struct in unregister_one_node(). But node struct is freed by node_device_release() which is called in unregister_node(). So by adding the kfree(), node struct is freed two times.

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 651e22f2701b "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.

2014-10-03m68k: Disable/restore interrupts in hwreg_present()/hwreg_write()Geert Uytterhoeven
hwreg_present() and hwreg_write() temporarily change the VBR register to another vector table. This table contains a valid bus error handler only, all other entries point to arbitrary addresses. If an interrupt comes in while the temporary table is active, the processor will start executing at such an arbitrary address, and the kernel will crash. While most callers run early, before interrupts are enabled, or explicitly disable interrupts, Finn Thain pointed out that macsonic has one callsite that doesn't, causing intermittent boot crashes. There's another unsafe callsite in hilkbd. Fix this for good by disabling and restoring interrupts inside hwreg_present() and hwreg_write(). Explicitly disabling interrupts can be removed from the callsites later.

2014-10-02mm: page_alloc: fix zone allocation fairness on UPJohannes Weiner
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 3a025760fc15 ("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.

2014-10-02mm: memcontrol: do not iterate uninitialized memcgsJohannes Weiner
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 d8ad30559715 ("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.
