Pull block IO poll support from Jens Axboe: "Various groups have been doing experimentation around IO polling for (really) fast devices. The code has been reviewed and has been sitting on the side for a few releases, but this is now good enough for coordinated benchmarking and further experimentation. Currently O_DIRECT sync read/write are supported. A framework is in the works that allows scalable stats tracking so we can auto-tune this. And we'll add libaio support as well soon.

Pull ARM SoC driver updates from Olof Johansson: "As we've enabled multiplatform kernels on ARM, and greatly done away with the contents under arch/arm/mach-*, there's still need for SoC-related drivers to go somewhere. Many of them go in through other driver trees, but we still have drivers/soc to hold some of the "doesn't fit anywhere" lowlevel code that might be shared between ARM and ARM64 (or just in general makes sense to not have under the architecture directory). This branch contains mostly such code: - Drivers for qualcomm SoCs for SMEM, SMD and SMD-RPM, used to communicate with power management blocks on these SoCs for use by clock, regulator and bus frequency drivers. - Allwinner Reduced Serial Bus driver, again used to communicate with PMICs. - Drivers for ARM's SCPI (System Control Processor). Not to be confused with PSCI (Power State Coordination Interface). SCPI is used to communicate with the assistant embedded cores doing power management, and we have yet to see how many of them will implement this for their hardware vs abstracting in other ways (or not at all like in the past). - To make confusion between SCPI and PSCI more likely, this release also includes an update of PSCI to interface version 1.0. - Rockchip support for power domains. - A driver to talk to the firmware on Raspberry Pi" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (57 commits) soc: qcom: smd-rpm: Correct size of outgoing message bus: sunxi-rsb: Add driver for Allwinner Reduced Serial Bus bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings ARM: bcm2835: add mutual inclusion protection drivers: psci: make PSCI 1.0 functions initialization version dependent dt-bindings: Correct paths in Rockchip power domains binding document soc: rockchip: power-domain: don't try to print the clock name in error case soc: qcom/smem: add HWSPINLOCK dependency clk: berlin: add cpuclk ARM: berlin: dts: add CLKID_CPU for BG2Q ARM: bcm2835: Add the Raspberry Pi firmware driver soc: qcom: smem: Move RPM message ram out of smem DT node soc: qcom: smd-rpm: Correct the active vs sleep state flagging soc: qcom: smd: delete unneeded of_node_put firmware: qcom-scm: build for correct architecture level soc: qcom: smd: Correct SMEM items for upper channels qcom-scm: add missing prototype for qcom_scm_is_available() qcom-scm: fix endianess issue in __qcom_scm_is_call_available soc: qcom: smd: Reject send of too big packets soc: qcom: smd: Handle big endian CPUs ...

In commit a1c34a3b ("mm: Don't offset memmap for flatmem") Laura fixed a problem for Srinivas relating to the bottom 2MB of RAM on an ARM IFC6410 board. One small wrinkle on ia64 is that it allocates the node_mem_map earlier in arch code, so it skips the block of code where "offset" is initialized. Move initialization of start and offset before the check for the node_mem_map so that they will always be available in the latter part of the function.

This reverts commit 34c2d9fb. There are 2 reasons for this revert: 1) The commit in question doesn't do what it says it does. The description reads: "Allow bridge forward delay to be configured when Spanning Tree is enabled." This was already the case before the commit was made. What the commit actually do was disallow invalid values or 'forward_delay' when STP was turned off. 2) The above change was actually a change in the user observed behavior and broke things like libvirt and other network configs that set 'forward_delay' to 0 without enabling STP. The value of 0 is actually used when STP is turned off to immediately mark the bridge as forwarding. Signed-off-by: NVlad Yasevich <vyasevic@redhat.com> Signed-off-by: NDavid S.

Arnd Bergmann reported: In my ARM randconfig tests, I'm getting a build error for newly added code in bpf_perf_event_read and bpf_perf_event_output whenever CONFIG_PERF_EVENTS is disabled: kernel/trace/bpf_trace.c: In function 'bpf_perf_event_read': kernel/trace/bpf_trace.c:203:11: error: 'struct perf_event' has no member named 'oncpu' if (event->oncpu != smp_processor_id() || ^ kernel/trace/bpf_trace.c:204:11: error: 'struct perf_event' has no member named 'pmu' event->pmu->count) This can happen when UPROBE_EVENT is enabled but KPROBE_EVENT is disabled. I'm not sure if that is a configuration we care about, otherwise we could prevent this case from occuring by adding Kconfig dependencies. Looking at this further, it's really that UPROBE_EVENT enables PERF_EVENTS. By just having BPF_EVENTS depend on PERF_EVENTS, then all is fine.

After changing an interface's MTU, then bringing the interface down and back up again, I immediately saw tons of kernel messages like below. The reason for this bad behavior is mvneta_rxq_drop_pkts(), which calls dma_unmap_single() on already-freed memory. So we need to switch the order of those two operations.

The ELF binary loader in binfmt_elf.c requires an MMU, making it impossible to use regular ELF binaries on NOMMU archs. However, the FDPIC ELF loader in binfmt_elf_fdpic.c is fully capable as a loader for plain ELF, which requires constant displacements between LOAD segments, since it already supports FDPIC ELF files flagged as needing constant displacement. This patch adjusts the FDPIC ELF loader to accept non-FDPIC ELF files on NOMMU archs. They are treated identically to FDPIC ELF files with the constant-displacement flag bit set, except for personality, which must match the ABI of the program being loaded; the PER_LINUX_FDPIC personality controls how the kernel interprets function pointers passed to sigaction. Files that do not set a stack size requirement explicitly are given a default stack size (matching the amount of committed stack the normal ELF loader for MMU archs would give them) rather than being rejected; this is necessary because plain ELF files generally do not declare stack requirements in theit program headers. Only ET_DYN (PIE) format ELF files are supported, since loading at a fixed virtual address is not possible on NOMMU. This patch was developed and tested on J2 (SH2-compatible) but should be usable immediately on all archs where binfmt_elf_fdpic is available. Moreover, by providing dummy definitions of the elf_check_fdpic() and elf_check_const_displacement() macros for archs which lack an FDPIC ABI, it should be possible to enable building of binfmt_elf_fdpic on all other NOMMU archs and thereby give them ELF binary support, but I have not yet tested this. The motivation for using binfmt_elf_fdpic.c rather than adapting binfmt_elf.c to NOMMU is that the former already has all the necessary code to work properly on NOMMU and has already received widespread real-world use and testing. I hope this is not controversial. I'm not really happy with having to unset the FDPIC_FUNCPTRS personality bit when loading non-FDPIC ELF. This bit should really reset automatically on execve, since otherwise, executing non-ELF binaries (e.g. bFLT) from an FDPIC process will leave the personality in the wrong state and severely break signal handling. But that's a separate, existing bug and I don't know the right place to fix it.
