Pull cgroup updates from Tejun Heo: "A lot of activities on cgroup side. Heavy restructuring including locking simplification took place to improve the code base and enable implementation of the unified hierarchy, which currently exists behind a __DEVEL__ mount option. The core support is mostly complete but individual controllers need further work. To explain the design and rationales of the the unified hierarchy Documentation/cgroups/unified-hierarchy.txt is added. Another notable change is css (cgroup_subsys_state - what each controller uses to identify and interact with a cgroup) iteration update. This is part of continuing updates on css object lifetime and visibility. cgroup started with reference count draining on removal way back and is now reaching a point where csses behave and are iterated like normal refcnted objects albeit with some complexities to allow distinguishing the state where they're being deleted.

This function is supposed to return true if the new load imbalance is worse than the old one. It didn't. I can only hope brown paper bags are in style. Now things converge much better on both the 4 node and 8 node systems. I am not sure why this did not seem to impact specjbb performance on the 4 node system, which is the system I have full-time access to.

shrink_inactive_list() used to wait 0.1s to avoid congestion when all the pages that were isolated from the inactive list were dirty but not under active writeback. That makes no real sense, and apparently causes major interactivity issues under some loads since 3.11. The ostensible reason for it was to wait for kswapd to start writing pages, but that seems questionable as well, since the congestion wait code seems to trigger for kswapd itself as well. Also, the logic behind delaying anything when we haven't actually started writeback is not clear - it only delays actually starting that writeback. We'll still trigger the congestion waiting if (a) the process is kswapd, and we hit pages flagged for immediate reclaim (b) the process is not kswapd, and the zone backing dev writeback is actually congested. This probably needs to be revisited, but as it is this fixes a reported regression.

commit 421e08c4 fixed the reported min/max for the X and Y axis, but unfortunately, it broke the resolution of those same axis. On the t540p, the resolution is the same regarding X and Y. It is not a problem for xf86-input-synaptics because this driver is only interested in the ratio between X and Y. Unfortunately, xf86-input-cmt uses directly the resolution, and having a null resolution leads to some divide by 0 errors, which are translated by -infinity in the resulting coordinates.

The touchpad on the GIGABYTE U2442 not only stops communicating when we try to set bit 3 (enable real hardware resolution) of reg_10, but on some BIOS versions also when we set bit 1 (enable two finger mode auto correct). I've asked the original reporter of: https://bugzilla.kernel.org/show_bug.cgi?id=61151 To check that not setting bit 1 does not lead to any adverse effects on his model / BIOS revision, and it does not, so this commit fixes the touchpad not working on these versions by simply never setting bit 1 for laptop models with the no_hw_res quirk.

At least the Dell Vostro 5470 elantech *clickpad* reports right button clicks when clicked in the right bottom area: https://bugzilla.redhat.com/show_bug.cgi?id=1103528 This is different from how (elantech) clickpads normally operate, normally no matter where the user clicks on the pad the pad always reports a left button event, since there is only 1 hardware button beneath the path. It looks like Dell has put 2 buttons under the pad, one under each bottom corner, causing this. Since this however still clearly is a real clickpad hardware-wise, we still want to report it as such to userspace, so that things like finger movement in the bottom area can be properly ignored as it should be on clickpads. So deal with this weirdness by simply mapping a right click to a left click on elantech clickpads. As an added advantage this is something which we can simply do on all elantech clickpads, so no need to add special quirks for this weird model.

Pull clock framework updates from Mike Turquette: "The clock framework changes for 3.16 are pretty typical: mostly clock driver additions and fixes. There are additions to the clock core code for some of the basic types (e.g. the common divider type has some fixes and featured added to it). One minor annoyance is a last-minute dependency that wasn't handled quite right. Commit ba0fae3b ("clk: berlin: add core clock driver for BG2/BG2CD") in this pull request depends on include/dt-bindings/clock/berlin2.h, which is already in your tree via the arm-soc pull request. Building for the berlin platform will break when the clk tree is built on it's own, but merged into your master branch everything should be fine" * tag 'clk-for-linus-3.16' of git://git.linaro.org/people/mike.turquette/linux: (75 commits) mmc: sunxi: Add driver for SD/MMC hosts found on Allwinner sunxi SoCs clk: export __clk_round_rate for providers clk: versatile: free icst on error return clk: qcom: Return error pointers for unimplemented clocks clk: qcom: Support msm8974pro global clock control hardware clk: qcom: Properly support display clocks on msm8974 clk: qcom: Support display RCG clocks clk: qcom: Return highest rate when round_rate() exceeds plan clk: qcom: Fix mmcc-8974's PLL configurations clk: qcom: Fix clk_rcg2_is_enabled() check clk: berlin: add core clock driver for BG2Q clk: berlin: add core clock driver for BG2/BG2CD clk: berlin: add driver for BG2x complex divider cells clk: berlin: add driver for BG2x simple PLLs clk: berlin: add driver for BG2x audio/video PLL clk: st: Terminate of match table clk/exynos4: Fix compilation warning ARM: shmobile: r8a7779: Add clock index macros for DT sources clk: divider: Fix overflow in clk_divider_bestdiv clk: u300: Terminate of match table ...

Pull exofs raid6 support from Boaz Harrosh: "These simple patches will enable raid6 using the kernel's raid6_pq engine for support under exofs and pnfs-objects. There is nothing needed to do at exofs and pnfs-obj. Just fire your mkfs.exofs with --raid=6 (that was already supported before) and off you go as usual. The ORE will pick up the new map and will start writing two devices of redundancy bits. The patches are so simple because most of the ORE was already for the general raid case, only a few bug fixes were needed and the actual wiring into the raid6_pq engine" * 'for-linus' of git://git.open-osd.org/linux-open-osd: ore: Support for raid 6 ore: Remove redundant dev_order(), more cleanups ore: (trivial) reformat some code

Pull x86 fixes from Peter Anvin: "A significantly larger than I'd like set of patches for just below the wire. All of these, however, fix real problems. The one thing that is genuinely scary in here is the change of SMP initialization, but that *does* fix a confirmed hang when booting virtual machines. There is also a patch to actually do the right thing about not offlining a CPU when there are not enough interrupt vectors available in the system; the accounting was done incorrectly. The worst case for that patch is that we fail to offline CPUs when we should (the new code is strictly more conservative than the old), so is not particularly risky. Most of the rest is minor stuff; the EFI patches are all about exporting correct information to boot loaders and kexec" * 'x86/urgent' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/boot: EFI_MIXED should not prohibit loading above 4G x86/smpboot: Initialize secondary CPU only if master CPU will wait for it x86/smpboot: Log error on secondary CPU wakeup failure at ERR level x86: Fix list/memory corruption on CPU hotplug x86: irq: Get correct available vectors for cpu disable x86/efi: Do not export efi runtime map in case old map x86/efi: earlyprintk=efi,keep fix

Patch to prevent warning of a buggy compiler when using clang and the ARM_UNWIND option. Clang defines (at least on the current trunk) GNUC, GNUC_MINOR, and GNUC_PATCHLEVEL to 4, 2, and 1 respectively. This version of GCC gets flagged as buggy, but it isn't actually an issue with clang so the patch will do what it did before unless clang is defined and then it will not report the GCC version as an issue.

With compilers which follow the C99 standard (like modern versions of gcc and clang), "extern inline" does the wrong thing (emits code for an externally linkable version of the inline function). "static inline" is the correct choice instead.

Both gcc (well, actually gnu as) and clang support the "-Wa,-gdwarf-2" option (though clang does not support "-Wa,--gdwarf-2"). Since these flags are equivalent in meaning, this patch uses the one which is better supported across compilers. Signed-off-by: Behan Webster <behanw@converseincode.com>
