Pull ARM SoC driver updates from Arnd Bergmann: "As usual, the drivers/tee and drivers/reset subsystems get merged here, with the expected set of smaller updates and some new hardware support. The tee subsystem now supports device drivers to be attached to a tee, the first example here is a random number driver with its implementation in the secure world. Three new power domain drivers get added for specific chip families: - Broadcom BCM283x chips (used in Raspberry Pi) - Qualcomm Snapdragon phone chips - Xilinx ZynqMP FPGA SoCs One new driver is added to talk to the BPMP firmware on NVIDIA Tegra210 Existing drivers are extended for new SoC variants from NXP, NVIDIA, Amlogic and Qualcomm" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (113 commits) tee: optee: update optee_msg.h and optee_smc.h to dual license tee: add cancellation support to client interface dpaa2-eth: configure the cache stashing amount on a queue soc: fsl: dpio: configure cache stashing destination soc: fsl: dpio: enable frame data cache stashing per software portal soc: fsl: guts: make fsl_guts_get_svr() static hwrng: make symbol 'optee_rng_id_table' static tee: optee: Fix unsigned comparison with less than zero hwrng: Fix unsigned comparison with less than zero tee: fix possible error pointer ctx dereferencing hwrng: optee: Initialize some structs using memset instead of braces tee: optee: Initialize some structs using memset instead of braces soc: fsl: dpio: fix memory leak of a struct qbman on error exit path clk: tegra: dfll: Make symbol 'tegra210_cpu_cvb_tables' static soc: qcom: llcc-slice: Fix typos qcom: soc: llcc-slice: Consolidate some code qcom: soc: llcc-slice: Clear the global drv_data pointer on error drivers: soc: xilinx: Add ZynqMP power domain driver firmware: xilinx: Add APIs to control node status/power dt-bindings: power: Add ZynqMP power domain bindings ...

Pull locking updates from Ingo Molnar: "The biggest part of this tree is the new auto-generated atomics API wrappers by Mark Rutland. The primary motivation was to allow instrumentation without uglifying the primary source code. The linecount increase comes from adding the auto-generated files to the Git space as well: include/asm-generic/atomic-instrumented.h | 1689 ++++++++++++++++-- include/asm-generic/atomic-long.h | 1174 ++++++++++--- include/linux/atomic-fallback.h | 2295 +++++++++++++++++++++++++ include/linux/atomic.h | 1241 +------------ I preferred this approach, so that the full call stack of the (already complex) locking APIs is still fully visible in 'git grep'. But if this is excessive we could certainly hide them. There's a separate build-time mechanism to determine whether the headers are out of date (they should never be stale if we do our job right). Anyway, nothing from this should be visible to regular kernel developers. Other changes: - Add support for dynamic keys, which removes a source of false positives in the workqueue code, among other things (Bart Van Assche) - Updates to tools/memory-model (Andrea Parri, Paul E. McKenney) - qspinlock, wake_q and lockdep micro-optimizations (Waiman Long) - misc other updates and enhancements" * 'locking-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (48 commits) locking/lockdep: Shrink struct lock_class_key locking/lockdep: Add module_param to enable consistency checks lockdep/lib/tests: Test dynamic key registration lockdep/lib/tests: Fix run_tests.sh kernel/workqueue: Use dynamic lockdep keys for workqueues locking/lockdep: Add support for dynamic keys locking/lockdep: Verify whether lock objects are small enough to be used as class keys locking/lockdep: Check data structure consistency locking/lockdep: Reuse lock chains that have been freed locking/lockdep: Fix a comment in add_chain_cache() locking/lockdep: Introduce lockdep_next_lockchain() and lock_chain_count() locking/lockdep: Reuse list entries that are no longer in use locking/lockdep: Free lock classes that are no longer in use locking/lockdep: Update two outdated comments locking/lockdep: Make it easy to detect whether or not inside a selftest locking/lockdep: Split lockdep_free_key_range() and lockdep_reset_lock() locking/lockdep: Initialize the locks_before and locks_after lists earlier locking/lockdep: Make zap_class() remove all matching lock order entries locking/lockdep: Reorder struct lock_class members locking/lockdep: Avoid that add_chain_cache() adds an invalid chain to the cache ...

Linux supports ELF binaries for ~25 years now. a.out coredumping has bitrotten quite significantly and would need some fixing to get it into shape again but considering how even the toolchains cannot create a.out executables in its default configuration, let's deprecate a.out support and remove it a couple of releases later, instead.

We're (finally) phasing out a.out support for good. As Borislav Petkov points out, we've supported ELF binaries for about 25 years by now, and coredumping in particular has bitrotted over the years. None of the tool chains even support generating a.out binaries any more, and the plan is to deprecate a.out support entirely for the kernel. But I want to start with just removing the core dumping code, because I can still imagine that somebody actually might want to support a.out as a simpler biinary format. Particularly if you generate some random binaries on the fly, ELF is a much more complicated format (admittedly ELF also does have a lot of toolchain support, mitigating that complexity a lot and you really should have moved over in the last 25 years). So it's at least somewhat possible that somebody out there has some workflow that still involves generating and running a.out executables. In contrast, it's very unlikely that anybody depends on debugging any legacy a.out core files. But regardless, I want this phase-out to be done in two steps, so that we can resurrect a.out support (if needed) without having to resurrect the core file dumping that is almost certainly not needed. Jann Horn pointed to the <asm/a.out-core.h> file that my first trivial cut at this had missed. And Alan Cox points out that the a.out binary loader _could_ be done in user space if somebody wants to, but we might keep just the loader in the kernel if somebody really wants it, since the loader isn't that big and has no really odd special cases like the core dumping does.

The current implementation of splice() and tee() ignores O_NONBLOCK set on pipe file descriptors and checks only the SPLICE_F_NONBLOCK flag for blocking on pipe arguments. This is inconsistent since splice()-ing from/to non-pipe file descriptors does take O_NONBLOCK into consideration. Fix this by promoting O_NONBLOCK, when set on a pipe, to SPLICE_F_NONBLOCK. Some context for how the current implementation of splice() leads to inconsistent behavior. In the ongoing work[1] to add VM tracing capability to trace-cmd we stream tracing data over named FIFOs or vsockets from guests back to the host. When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on the input file descriptor and set SPLICE_F_NONBLOCK for the next call to splice(). If splice() was blocked waiting on data from the input FIFO, after SIGINT splice() restarts with the same arguments (no SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no data is available. This differs from the splice() behavior when reading from a vsocket or when we're doing a traditional read()/write() loop (trace-cmd's --nosplice argument). With this patch applied we get the same behavior in all situations after setting O_NONBLOCK which also matches the behavior of doing a read()/write() loop instead of splice(). This change does have potential of breaking users who don't expect EAGAIN from splice() when SPLICE_F_NONBLOCK is not set. OTOH programs that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2].

When CONFIG_SYSCTL is turned off, we get a link failure for the newly introduced tuning knob. net/ipv6/addrconf.o: In function `addrconf_init_net': addrconf.c:(.text+0x31dc): undefined reference to `sysctl_devconf_inherit_init_net' Add an IS_ENABLED() check to fall back to the default behavior (sysctl_devconf_inherit_init_net=0) here.
