The example in the BCM43xx documentation uses "brcmf" as node name. However, wireless devices should be named "wifi" instead.

Pull thermal management updates from Zhang Rui: - Fix a problem where orderly_shutdown() is called for multiple times due to multiple critical overheating events raised in a short period by platform thermal driver. (Keerthy) - Introduce a backup thermal shutdown mechanism, which invokes kernel_power_off()/emergency_restart() directly, after orderly_shutdown() being issued for certain amount of time(specified via Kconfig). This is useful in certain conditions that userspace may be unable to power off the system in a clean manner and leaves the system in a critical state, like in the middle of driver probing phase. (Keerthy) - Introduce a new interface in thermal devfreq_cooling code so that the driver can provide more precise data regarding actual power to the thermal governor every time the power budget is calculated. (Lukasz Luba) - Introduce BCM 2835 soc thermal driver and northstar thermal driver, within a new sub-folder. (Rafał Miłecki) - Introduce DA9062/61 thermal driver.

Pull TEE driver infrastructure and OP-TEE drivers from Arnd Bergmann: "This introduces a generic TEE framework in the kernel, to handle trusted environemtns (security coprocessor or software implementations such as OP-TEE/TrustZone). I'm sending it separately from the other arm-soc driver changes to give it a little more visibility, once the subsystem is merged, we will likely keep this in the arm₋soc drivers branch or have the maintainers submit pull requests directly, depending on the patch volume. I have reviewed earlier versions in the past, and have reviewed the latest version in person during Linaro Connect BUD17. Here is my overall assessment of the subsystem: - There is clearly demand for this, both for the generic infrastructure and the specific OP-TEE implementation. - The code has gone through a large number of reviews, and the review comments have all been addressed, but the reviews were not coming up with serious issues any more and nobody volunteered to vouch for the quality. - The user space ioctl interface is sufficient to work with the OP-TEE driver, and it should in principle work with other TEE implementations that follow the GlobalPlatform[1] standards, but it might need to be extended in minor ways depending on specific requirements of future TEE implementations - The main downside of the API to me is how the user space is tied to the TEE implementation in hardware or firmware, but uses a generic way to communicate with it. This seems to be an inherent problem with what it is trying to do, and I could not come up with any better solution than what is implemented here.

2017-05-11uapi: export all arch specifics directoriesNicolas Dichtel1-14/+1
This patch removes the need of subdir-y. Now all files/directories under arch/<arch>/include/uapi/ are exported. The only change for userland is the layout of the command 'make headers_install_all': directories asm-<arch> are replaced by arch-<arch>/. Those new directories contains all files/directories of the specified arch. Note that only cris and tile have more directories than only asm: - arch-v[10|32] for cris; - arch for tile.

2017-05-11uapi: export all headers under uapi directoriesNicolas Dichtel1-25/+41
Regularly, when a new header is created in include/uapi/, the developer forgets to add it in the corresponding Kbuild file. This error is usually detected after the release is out. In fact, all headers under uapi directories should be exported, thus it's useless to have an exhaustive list. After this patch, the following files, which were not exported, are now exported (with make headers_install_all): asm-arc/kvm_para.h asm-arc/ucontext.h asm-blackfin/shmparam.h asm-blackfin/ucontext.h asm-c6x/shmparam.h asm-c6x/ucontext.h asm-cris/kvm_para.h asm-h8300/shmparam.h asm-h8300/ucontext.h asm-hexagon/shmparam.h asm-m32r/kvm_para.h asm-m68k/kvm_para.h asm-m68k/shmparam.h asm-metag/kvm_para.h asm-metag/shmparam.h asm-metag/ucontext.h asm-mips/hwcap.h asm-mips/reg.h asm-mips/ucontext.h asm-nios2/kvm_para.h asm-nios2/ucontext.h asm-openrisc/shmparam.h asm-parisc/kvm_para.h asm-powerpc/perf_regs.h asm-sh/kvm_para.h asm-sh/ucontext.h asm-tile/shmparam.h asm-unicore32/shmparam.h asm-unicore32/ucontext.h asm-x86/hwcap2.h asm-xtensa/kvm_para.h drm/armada_drm.h drm/etnaviv_drm.h drm/vgem_drm.h linux/aspeed-lpc-ctrl.h linux/auto_dev-ioctl.h linux/bcache.h linux/btrfs_tree.h linux/can/vxcan.h linux/cifs/cifs_mount.h linux/coresight-stm.h linux/cryptouser.h linux/fsmap.h linux/genwqe/genwqe_card.h linux/hash_info.h linux/kcm.h linux/kcov.h linux/kfd_ioctl.h linux/lightnvm.h linux/module.h linux/nbd-netlink.h linux/nilfs2_api.h linux/nilfs2_ondisk.h linux/nsfs.h linux/pr.h linux/qrtr.h linux/rpmsg.h linux/sched/types.h linux/sed-opal.h linux/smc.h linux/smc_diag.h linux/stm.h linux/switchtec_ioctl.h linux/vfio_ccw.h linux/wil6210_uapi.h rdma/bnxt_re-abi.h Note that I have removed from this list the files which are generated in every exported directories (like .install or .install.cmd).

2017-05-10block, bfq: stress that low_latency must be off to get max throughputPaolo Valente1-1/+16
The introduction of the BFQ and Kyber I/O schedulers has triggered a new wave of I/O benchmarks. Unfortunately, comments and discussions on these benchmarks confirm that there is still little awareness that it is very hard to achieve, at the same time, a low latency and a high throughput. In particular, virtually all benchmarks measure throughput, or throughput-related figures of merit, but, for BFQ, they use the scheduler in its default configuration. This configuration is geared, instead, toward a low latency. This is evidently a sign that BFQ documentation is still too unclear on this important aspect. This commit addresses this issue by stressing how BFQ configuration must be (easily) changed if the only goal is maximum throughput.

Pull ARM Device-tree updates from Olof Johansson: "Device-tree continues to see lots of updates. The majority of patches here are smaller changes for new hardware on existing platforms, and there are a few larger changes worth pointing out. Major new platforms: - Gemini has been ported to DT, so a handful of "new" platforms moved over from board files - Rockchip RK3288 support for Tinkerboard and Phytec phyCORE-RK3288 SoM and RDK - A bunch of embedded platforms, several Linksys platforms, Synology DS116, - Motorola Droid4 (really old OMAP-based phone) support is added. Some refactorings, i.e. Allwinner H3/H5 support is commonalized. And lots of smaller changes, cleanups, etc. See shortlog for more description We're adding ability to cross-include DT files between arm and arm64, by creating appropriate links in the dt-include directory, and using arm/ and arm64/ as include prefixes. This will avoid other local hacks such as per-file links between the two arch trees (this broke for external mirroring of DT contents).

2017-05-09arm64: documentation: document tagged pointer stack constraintsKristina Martsenko1-15/+47
Some kernel features don't currently work if a task puts a non-zero address tag in its stack pointer, frame pointer, or frame record entries (FP, LR). For example, with a tagged stack pointer, the kernel can't deliver signals to the process, and the task is killed instead. As another example, with a tagged frame pointer or frame records, perf fails to generate call graphs or resolve symbols. For now, just document these limitations, instead of finding and fixing everything that doesn't work, as it's not known if anyone needs to use tags in these places anyway. In addition, as requested by Dave Martin, generalize the limitations into a general kernel address tag policy, and refactor tagged-pointers.txt to include it. Fixes: d50240a5f6ce ("arm64: mm: permit use of tagged pointers at EL0") Cc: <stable@vger.kernel.org> # 3.12.x- Reviewed-by: Dave Martin <Dave.Martin@arm.com> Acked-by: Will Deacon <will.deacon@arm.com> Signed-off-by: Kristina Martsenko <kristina.martsenko@arm.com> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>
