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.

Kbuild UAPI header export updates for v4.12
Improvement of headers_install by Nicolas Dichtel. It has been long since the introduction of uapi directories, but the de-coupling of exported headers has not been completed. Headers listed in header-y are exported whether they exist in uapi directories or not. His work fixes this inconsistency. All (and only) headers under uapi directories are now exported.

TEE driver infrastructure and OP-TEE drivers
This branch 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.

uapi: export all arch specifics directories
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.

uapi: export all headers under uapi directories
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).

block, bfq: stress that low_latency must be off to get max throughput
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.

ARM: Device-tree updates
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). Now they can just provide their own appropriate dt-include hierarcy per platform. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJZEAoxAAoJEIwa5zzehBx3li8P/iIMy0HmGuJ0JsTldMk4kgkM 1Ci/gcgKYn43m68RwvZCwkBxVibqCdMbBtLHCUt3ScGIYdj6mUG8axRHvFW/tsGf BP0Y5pxm7l1BlHOKed97bJUeMyqqG13szzS7aB5L6cyZt41lAAkpCx4OFAuIlaxo XM1v2xRSxqSf/zp4px83qX2hdHIpe4ZGlDiNh8rCBBnKMY4PqhK0V7TFLPOKbFnr stIvD1TpvzacN67JVo1En0rCFgXSCwJ+CTumAOIx4tflV48ymY5THRNtI1ogFosc 1IfOxnC9DyRVM2ubFF7/ZLFbmn5KHu6ZwPLN+8Wl2McbT96PAtJ3h/zgTnuk4Tvf GaAfqcyAXFeiZGU+bkkGiaQwXRDBroxVuNFTgERNgF70GUrDpBzd3tJO2rx7oZCS Rj2QvKfBDBr9g5ldVGjOBIq/G9DeN5TtR6gyr/hCS/nm0NlYQ90Pzing0Nj8PDC9 /AOa4k4wUWo/oaFucBEeATCxto3TKpmBuP1I31sWG8StKVSJbIek2dSMcWSVFrG5 6/pzmuE4C7ZlshcFAUOeHxMVjBhTya5mDZQgZhCAnwhVMzrrpMTHTi27nbWcv/k8 9TH+ig5DoKL65FFE92ZkEb4S47SaD2+qKjEzJMDNQzc5WuY4l7pfDQoSn3YLjzKZ xSKQEsmyOW0/0v8ecDKP =v6w6 -----END PGP SIGNATURE----- Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM Device-tree updates from Olof Johansson: "Device-tree continues to see lots of updates.

arm64: documentation: document tagged pointer stack constraints
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.

powerpc/64s: Support new device tree binding for discovering CPU features
The ibm,powerpc-cpu-features device tree binding describes CPU features with ASCII names and extensible compatibility, privilege, and enablement metadata that allows improved flexibility and compatibility with new hardware. The interface is described in detail in ibm,powerpc-cpu-features.txt in this patch. Currently this code is not enabled by default, and there are no released firmwares that provide the binding.

TTY/Serial patches for 4.12-rc1
Here is the "big" TTY/Serial patch updates for 4.12-rc1 Not a lot of new things here, the normal number of serial driver updates and additions, tiny bugs fixed, and some core files split up to make future changes a bit easier for Nicolas's "tiny-tty" work. All of these have been in linux-next for a while. There will be a merge conflict with include/linux/serdev.h coming from the bluetooth tree merge, which we knew about, as we wanted some of the serdev changes to go in through that tree. I'll send the expected merge result as a follow-on message.

powerpc/fadump: update documentation about crashkernel parameter reuse
As we are reusing crashkernel parameter instead of fadump_reserve_mem parameter to specify the memory to reserve for fadump's crash kernel, update the documentation accordingly.
