I'm announcing the release of the 3.16.76 kernel. All users of the 3.16 kernel series should upgrade. The updated 3.16.y git tree can be found at: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git linux-3.16.y and can be browsed at the normal kernel.org git web browser: https://git.kernel.org/?p=linux/kernel/git/stable/linux-stable.git The diff from 3.16.75 is attached to this message.

[PATCH net-next 10/10 v2] net: ethernet: ixp4xx: Use parent dev for DMA pool

by Linus Walleij

Use the netdevice struct device .parent field when calling dma_pool_create(): the .dma_coherent_mask and .dma_mask pertains to the bus device on the hardware (platform) bus in this case, not the struct device inside the network device. This makes the pool allocation work.

[PATCH v2 0/2] PCI: rcar: Fix missing MACCTLR register setting (take2)

by Yoshihiro Shimoda

This patch series is based on the latest pci/rcar branch of Lorenzo's pci.git. The commit 175cc093888e ("PCI: rcar: Fix missing MACCTLR register setting in rcar_pcie_hw_init()") description/code don't follow the manual accurately, so that it's difficult to understand. So, this patch series reverts the commit at first, and then applies a new fixed patch. Reference: https://marc.info/?l=linux-renesas-soc&m=157242422327368&w=2 Changes from v1: - Follow -stable rule in patch 1/2. - Add some comments about SPCHG bit of MACCTLR register. https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=195717 Yoshihiro Shimoda (2): Revert "PCI: rcar: Fix missing MACCTLR register setting in rcar_pcie_hw_init()" PCI: rcar: Fix missing MACCTLR register setting in initialize sequence drivers/pci/controller/pcie-rcar.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) -- 2.7.4

[PATCH v4 1/2] sched/topology: Don't try to build empty sched domains

by Valentin Schneider

Turns out hotplugging CPUs that are in exclusive cpusets can lead to the cpuset code feeding empty cpumasks to the sched domain rebuild machinery. This leads to the following splat: [ 30.618174] Internal error: Oops: 96000004 [#1] PREEMPT SMP [ 30.623697] Modules linked in: [ 30.626731] CPU: 0 PID: 235 Comm: kworker/5:2 Not tainted 5.4.0-rc1-00005-g8d495477d62e #23 [ 30.635003] Hardware name: ARM Juno development board (r0) (DT) [ 30.640877] Workqueue: events cpuset_hotplug_workfn [ 30.645713] pstate: 60000005 (nZCv daif -PAN -UAO) [ 30.650464] pc : build_sched_domains (./include/linux/arch_topology.h:23 kernel/sched/topology.c:1898 kernel/sched/topology.c:1969) [ 30.655126] lr : build_sched_domains (kernel/sched/topology.c:1966) [...] [ 30.742047] Call trace: [ 30.744474] build_sched_domains (./include/linux/arch_topology.h:23 kernel/sched/topology.c:1898 kernel/sched/topology.c:1969) [ 30.748793] partition_sched_domains_locked (kernel/sched/topology.c:2250) [ 30.753971] rebuild_sched_domains_locked (./include/linux/bitmap.h:370 ./include/linux/cpumask.h:538 kernel/cgroup/cpuset.c:955 kernel/cgroup/cpuset.c:978 kernel/cgroup/cpuset.c:1019) [ 30.758977] rebuild_sched_domains (kernel/cgroup/cpuset.c:1032) [ 30.763209] cpuset_hotplug_workfn (kernel/cgroup/cpuset.c:3205 (discriminator 2)) [ 30.767613] process_one_work (./arch/arm64/include/asm/jump_label.h:21 ./include/linux/jump_label.h:200 ./include/trace/events/workqueue.h:114 kernel/workqueue.c:2274) [ 30.771586] worker_thread (./include/linux/compiler.h:199 ./include/linux/list.h:268 kernel/workqueue.c:2416) [ 30.775217] kthread (kernel/kthread.c:255) [ 30.778418] ret_from_fork (arch/arm64/kernel/entry.S:1167) [ 30.781965] Code: f860dae2 912802d6 aa1603e1 12800000 (f8616853) The faulty line in question is cap = arch_scale_cpu_capacity(cpumask_first(cpu_map)); and we're not checking the return value against nr_cpu_ids (we shouldn't have to!), which leads to the above.

[v4.14.y] net_sched: check cops->tcf_block in tc_bind_tclass()

by Zubin Mithra

From: Cong Wang <xiyou.wangcong(a)gmail.com> commit 8b142a00edcf8422ca48b8de88d286efb500cb53 upstream At least sch_red and sch_tbf don't implement ->tcf_block() while still have a non-zero tc "class". Instead of adding nop implementations to each of such qdisc's, we can just relax the check of cops->tcf_block() in tc_bind_tclass(). They don't support TC filter anyway.

+ mm-mempolicy-fix-the-wrong-return-value-and-potential-pages-leak-of-mbind.patch added to -mm tree

The patch titled Subject: mm: mempolicy: fix the wrong return value and potential pages leak of mbind has been added to the -mm tree. Its filename is mm-mempolicy-fix-the-wrong-return-value-and-potential-pages-leak-of-mbind.patch This patch should soon appear at http://ozlabs.org/~akpm/mmots/broken-out/mm-mempolicy-fix-the-wrong-return-… and later at http://ozlabs.org/~akpm/mmotm/broken-out/mm-mempolicy-fix-the-wrong-return-… Before you just go and hit "reply", please: a) Consider who else should be cc'ed b) Prefer to cc a suitable mailing list as well c) Ideally: find the original patch on the mailing list and do a reply-to-all to that, adding suitable additional cc's *** Remember to use Documentation/process/submit-checklist.rst when testing your code *** The -mm tree is included into linux-next and is updated there every 3-4 working days ------------------------------------------------------ From: Yang Shi <yang.shi(a)linux.alibaba.com> Subject: mm: mempolicy: fix the wrong return value and potential pages leak of mbind Commit d883544515aa ("mm: mempolicy: make the behavior consistent when MPOL_MF_MOVE* and MPOL_MF_STRICT were specified") fixed the return value of mbind() for a couple of corner cases. But, it altered the errno for some other cases, for example, mbind() should return -EFAULT when part or all of the memory range specified by nodemask and maxnode points outside your accessible address space, or there was an unmapped hole in the specified memory range specified by addr and len. Fix this by preserving the errno returned by queue_pages_range(). And, the pagelist may be not empty even though queue_pages_range() returns error, put the pages back to LRU since mbind_range() is not called to really apply the policy so those pages should not be migrated, this is also the old behavior before the problematic commit.

[PATCH 1/2] remoteproc: qcom_q6v5_mss: Don't reassign mpss region on shutdown

by Bjorn Andersson

Trying to reclaim mpss memory while the mba is not running causes the system to crash on devices with security fuses blown, so leave it assigned to the remote on shutdown and recover it on a subsequent boot.

[PATCH] KEYS: asym_tpm: Switch to get_random_bytes()

by Jarkko Sakkinen

Only the kernel random pool should be used for generating random numbers. TPM contributes to that pool among the other sources of entropy. In here it is not, agreed, absolutely critical because TPM is what is trusted anyway but in order to remove tpm_get_random() we need to first remove all the call sites.

[PATCH v2 03/11] DTS: ARM: pandora-common: define wl1251 as child node of mmc3

by H. Nikolaus Schaller

Since v4.7 the dma initialization requires that there is a device tree property for "rx" and "tx" channels which is not provided by the pdata-quirks initialization. By conversion of the mmc3 setup to device tree this will finally allows to remove the OpenPandora wlan specific omap3 data-quirks.
