md updates for 4.4.
Two major components to this update. 1/ the clustered-raid1 support from SUSE is nearly complete. There are a few outstanding issues being worked on. Maybe half a dozen patches will bring this to a usable state. 2/ The first stage of journalled-raid5 support from Facebook makes an appearance. With a journal device configured (typically NVRAM or SSD), the "RAID5 write hole" should be closed - a crash during degraded operations cannot result in data corruption. The next stage will be to use the journal as a write-behind cache so that latency can be reduced and in some cases throughput increased by performing more full-stripe writes. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJWNX9RAAoJEDnsnt1WYoG5bYMP/jI0pV3wcbs7mZQAa8S/V0lU 2l25x4MdwDvqVKMfjIc/C5J08QNgcrgSvhiVPCEOK0w18q395vep9f6gFKbMHhu/ lWU3PLHGw8XBHp5yEnxrpQkN0pRrNjh5NqIdlVMBNyL6u+RZPS2ZuzxJ8wiNAFg1 MypNkgoUu6s+nBp4DWWnMGYhBc+szBR+gTYAzGiZ8vqOH9uiSJ2SsGG5aRVUN/af oMYvJAf9aA6uj+xSzNlXIaLfWJIrshQYS1jU/W4gTm0DwK9yqbTxvubJaE0SGu/o 73FGU8tmQ6ELYfsp3D/jmfUkE7weiNEQhdVb/4wy1A/SGc+W7Ju9pxfhm8ra57s0 /BCkfwWZXEvx1flegXfK1mC6EMpMIcGAD2FQEhmQbW6wTdDwtNyEhIePDVGJwD/F rhEThFa+Dg9+xnBGnS6OUK3EpXgml2hAeAC7uA3TVSAnWd/9/Mpim6fZhqrB/v9L Ik0tZt+H4nxYaheZjKlKhuXUQYcUWGiMb67bGMem/YAlMa4y9C9qF+9mPXxyjVlI hBsd5SfZNz99DyB/bO8BumQeIWlTfzLeFzWW67eQ864LRKO6k0/VIbPZHCfn2oVG XvyC2fUhNOIURP3IMxcyHYxOA7Mu6EDsVVDTpuqLVbZQ5IPjDEfQ54yB/BLUvbX/ Gh2/tKn7Xc25HuLAFEbs =TD5o -----END PGP SIGNATURE----- Merge tag 'md/4.4' of git://neil.brown.name/md Pull md updates from Neil Brown: "Two major components to this update. 1) The clustered-raid1 support from SUSE is nearly complete.

Power management and ACPI updates for v4.4-rc1
- ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes). / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJWOC9oAAoJEILEb/54YlRx/c8P/joflwoFsISwJccG62YTQMuc bMQKM4Kw0vl5La8+pkLpe5t6+mW7l81UFtYF6Dzd8LOKlD9sszD34z1lHmCeT/oR wn0uZpHagRyLMUfoyiEtlU/VRU6WQNNtS3EgjwUi7xgFz9Q0pjcCZ9OQ6vKov1j5 +6j40ODif5sgo+2vl+rztJiV0SIMkYdkgNqgfN1FE9bdLA2Zkk+PxxJbtGQORuDu O/K+XhQT2xWquVWi/1p+VtQxs5glBS1oKm0kogV5bElCvNTRNIVABUNcjogITQwo QSAKgoCKIoaIl5jtDT6u5dc0y67q/dMtqOY9fOCcOz1Z7jbWQzR8D7mpFWIsJUPK K2LClI3t85ynpN6Jref246A6+C9nwB8JMAiAR11oBw7WbBlkd6tbRgcT5B+iz8UE FuCCif7pha/Fs+Jt1YRazscIqteQ2bAhhxikuIPMfw2M6M67MNfVNeKA1bAoSM34 dH7JsilblitvV7shrwJHwXPXCOF2jEPoK8I4/q2+TR5qUxEpRJjelQxXGSaQScMZ iNnjeTgv8H8q+rY5Yjzsl4pxP0Fvf7IuqkptWOJbgepg4cQc9pS87wOpY3uEeQzr H7ruaQJFCnLO4aXbPNClsiJARhrBk+qMlsh4vBEyCJ2T0ucb+nIUcN4BTi8t85yl X97BfHHUiDoUrnIsNids =1gaH -----END PGP SIGNATURE----- Merge tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull power management and ACPI updates from Rafael Wysocki: "Quite a new features are included this time.

Next, the ACPI core and the generic device properties API will now support a recently introduced hierarchical properties extension of the _DSD (Device Specific Data) ACPI device configuration object. If the ACPI platform firmware uses that extension to organize device properties in a hierarchical way, the kernel will automatically handle it and make those properties available to device drivers via the generic device properties API. It also will be possible to build the ACPICA's AML interpreter debugger into the kernel now and use that to diagnose AML-related problems more efficiently. In the future, this should make it possible to single-step AML execution and do similar things. Interesting stuff, although somewhat experimental at this point. Finally, the PM core gets a new mechanism that can be used by device drivers to distinguish between suspend-to-RAM (based on platform firmware support) and suspend-to-idle (or other variants of system suspend the platform firmware is not involved in) and possibly optimize their device suspend/resume handling accordingly. In addition to that, some existing features are re-organized quite substantially. First, the ACPI-based handling of PCI host bridges on x86 and ia64 is unified and the common code goes into the ACPI core (so as to reduce code duplication and eliminate non-essential differences between the two architectures in that area). Second, the Operating Performance Points (OPP) framework is reorganized to make the code easier to find and follow. Next, the cpufreq core's sysfs interface is reorganized to get rid of the "primary CPU" concept for configurations in which the same performance scaling settings are shared between multiple CPUs. Finally, some interfaces that aren't necessary any more are dropped from the generic power domains framework. On top of the above we have some minor extensions, cleanups and bug fixes in multiple places, as usual. Specifics: - ACPICA update to upstream revision 20150930 (Bob Moore, Lv Zheng). The most significant change is to allow the AML debugger to be built into the kernel. On top of that there is an update related to the NFIT table (the ACPI persistent memory interface) and a few fixes and cleanups. - ACPI CPPC2 (Collaborative Processor Performance Control v2) support along with a cpufreq frontend (Ashwin Chaugule). This can only be enabled on ARM64 at this point. - New ACPI infrastructure for the early probing of IRQ chips and clock sources (Marc Zyngier). - Support for a new hierarchical properties extension of the ACPI _DSD (Device Specific Data) device configuration object allowing the kernel to handle hierarchical properties (provided by the platform firmware this way) automatically and make them available to device drivers via the generic device properties interface (Rafael Wysocki). - Generic device properties API extension to obtain an index of certain string value in an array of strings, along the lines of of_property_match_string(), but working for all of the supported firmware node types, and support for the "dma-names" device property based on it (Mika Westerberg). - ACPI core fix to parse the MADT (Multiple APIC Description Table) entries in the order expected by platform firmware (and mandated by the specification) to avoid confusion on systems with more than 255 logical CPUs (Lukasz Anaczkowski). - Consolidation of the ACPI-based handling of PCI host bridges on x86 and ia64 (Jiang Liu). - ACPI core fixes to ensure that the correct IRQ number is used to represent the SCI (System Control Interrupt) in the cases when it has been re-mapped (Chen Yu). - New ACPI backlight quirk for Lenovo IdeaPad S405 (Hans de Goede). - ACPI EC driver fixes (Lv Zheng). - Assorted ACPI fixes and cleanups (Dan Carpenter, Insu Yun, Jiri Kosina, Rami Rosen, Rasmus Villemoes). - New mechanism in the PM core allowing drivers to check if the platform firmware is going to be involved in the upcoming system suspend or if it has been involved in the suspend the system is resuming from at the moment (Rafael Wysocki). This should allow drivers to optimize their suspend/resume handling in some cases and the changes include a couple of users of it (the i8042 input driver, PCI PM). - PCI PM fix to prevent runtime-suspended devices with PME enabled from being resumed during system suspend even if they aren't configured to wake up the system from sleep (Rafael Wysocki). - New mechanism to report the number of a wakeup IRQ that woke up the system from sleep last time (Alexandra Yates). - Removal of unused interfaces from the generic power domains framework and fixes related to latency measurements in that code (Ulf Hansson, Daniel Lezcano). - cpufreq core sysfs interface rework to make it handle CPUs that share performance scaling settings (represented by a common cpufreq policy object) more symmetrically (Viresh Kumar). This should help to simplify the CPU offline/online handling among other things. - cpufreq core fixes and cleanups (Viresh Kumar). - intel_pstate fixes related to the Turbo Activation Ratio (TAR) mechanism on client platforms which causes the turbo P-states range to vary depending on platform firmware settings (Srinivas Pandruvada). - intel_pstate sysfs interface fix (Prarit Bhargava). - Assorted cpufreq driver (imx, tegra20, powernv, integrator) fixes and cleanups (Bai Ping, Bartlomiej Zolnierkiewicz, Shilpasri G Bhat, Luis de Bethencourt). - cpuidle mvebu driver cleanups (Russell King). - OPP (Operating Performance Points) framework code reorganization to make it more maintainable (Viresh Kumar). - Intel Broxton support for the RAPL (Running Average Power Limits) power capping driver (Amy Wiles). - Assorted power management code fixes and cleanups (Dan Carpenter, Geert Uytterhoeven, Geliang Tang, Luis de Bethencourt, Rasmus Villemoes)" * tag 'pm+acpi-4.4-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (108 commits) cpufreq: postfix policy directory with the first CPU in related_cpus cpufreq: create cpu/cpufreq/policyX directories cpufreq: remove cpufreq_sysfs_{create|remove}_file() cpufreq: create cpu/cpufreq at boot time cpufreq: Use cpumask_copy instead of cpumask_or to copy a mask cpufreq: ondemand: Drop unnecessary locks from update_sampling_rate() PM / Domains: Merge measurements for PM QoS device latencies PM / Domains: Don't measure ->start|stop() latency in system PM callbacks PM / clk: Fix broken build due to non-matching code and header #ifdefs ACPI / Documentation: add copy_dsdt to ACPI format options ACPI / sysfs: correctly check failing memory allocation ACPI / video: Add a quirk to force native backlight on Lenovo IdeaPad S405 ACPI / CPPC: Fix potential memory leak ACPI / CPPC: signedness bug in register_pcc_channel() ACPI / PAD: power_saving_thread() is not freezable ACPI / PM: Fix incorrect wakeup IRQ setting during suspend-to-idle ACPI: Using correct irq when waiting for events ACPI: Use correct IRQ when uninstalling ACPI interrupt handler cpuidle: mvebu: disable the bind/unbind attributes and use builtin_platform_driver cpuidle: mvebu: clean up multiple platform drivers ... |

(Kan Liang) - Add group read support to perf_event_read(). (Peter Zijlstra) - Branch call hardware sampling support, implemented on x86 and PowerPC. (Stephane Eranian) - Event groups transactional interface enhancements. (Sukadev Bhattiprolu) - Enable proper x86/intel/uncore PMU support on multi-segment PCI systems. (Taku Izumi) - ... misc fixes and cleanups. The perf tooling team was very busy again with 200+ commits, the full diff doesn't fit into lkml size limits. Here's an (incomplete) list of the tooling highlights: New features: - Change the default event used in all tools (record/top): use the most precise "cycles" hw counter available, i.e. when the user doesn't specify any event, it will try using cycles:ppp, cycles:pp, etc and fall back transparently until it finds a working counter. (Arnaldo Carvalho de Melo) - Integration of perf with eBPF that, given an eBPF .c source file (or .o file built for the 'bpf' target with clang), will get it automatically built, validated and loaded into the kernel via the sys_bpf syscall, which can then be used and seen using 'perf trace' and other tools. (Wang Nan) Various user interface improvements: - Automatic pager invocation on long help output. (Namhyung Kim) - Search for more options when passing args to -h, e.g.: (Arnaldo Carvalho de Melo) $ perf report -h interface Usage: perf report [<options>] --gtk Use the GTK2 interface --stdio Use the stdio interface --tui Use the TUI interface - Show ordered command line options when -h is used or when an unknown option is specified. (Arnaldo Carvalho de Melo) - If options are passed after -h, show just its descriptions, not all options. (Arnaldo Carvalho de Melo) - Implement column based horizontal scrolling in the hists browser (top, report), making it possible to use the TUI for things like 'perf mem report' where there are many more columns than can fit in a terminal. (Arnaldo Carvalho de Melo) - Enhance the error reporting of tracepoint event parsing, e.g.: $ oldperf record -e sched:sched_switc usleep 1 event syntax error: 'sched:sched_switc' \___ unknown tracepoint Run 'perf list' for a list of valid events Now we get the much nicer: $ perf record -e sched:sched_switc ls event syntax error: 'sched:sched_switc' \___ can't access trace events Error: No permissions to read /sys/kernel/debug/tracing/events/sched/sched_switc Hint: Try 'sudo mount -o remount,mode=755 /sys/kernel/debug' And after we have those mount point permissions fixed: $ perf record -e sched:sched_switc ls event syntax error: 'sched:sched_switc' \___ unknown tracepoint Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not found. Hint: Perhaps this kernel misses some CONFIG_ setting to enable this feature?. I.e. basically now the event parsing routing uses the strerror_open() routines introduced by and used in 'perf trace' work. (Jiri Olsa) - Fail properly when pattern matching fails to find a tracepoint, i.e. '-e non:existent' was being correctly handled, with a proper error message about that not being a valid event, but '-e non:existent*' wasn't, fix it. (Jiri Olsa) - Do event name substring search as last resort in 'perf list'. (Arnaldo Carvalho de Melo) E.g.: # perf list clock List of pre-defined events (to be used in -e): cpu-clock [Software event] task-clock [Software event] uncore_cbox_0/clockticks/ [Kernel PMU event] uncore_cbox_1/clockticks/ [Kernel PMU event] kvm:kvm_pvclock_update [Tracepoint event] kvm:kvm_update_master_clock [Tracepoint event] power:clock_disable [Tracepoint event] power:clock_enable [Tracepoint event] power:clock_set_rate [Tracepoint event] syscalls:sys_enter_clock_adjtime [Tracepoint event] syscalls:sys_enter_clock_getres [Tracepoint event] syscalls:sys_enter_clock_gettime [Tracepoint event] syscalls:sys_enter_clock_nanosleep [Tracepoint event] syscalls:sys_enter_clock_settime [Tracepoint event] syscalls:sys_exit_clock_adjtime [Tracepoint event] syscalls:sys_exit_clock_getres [Tracepoint event] syscalls:sys_exit_clock_gettime [Tracepoint event] syscalls:sys_exit_clock_nanosleep [Tracepoint event] syscalls:sys_exit_clock_settime [Tracepoint event] Intel PT hardware tracing enhancements: - Accept a zero --itrace period, meaning "as often as possible". In the case of Intel PT that is the same as a period of 1 and a unit of 'instructions' (i.e. --itrace=i1i). (Adrian Hunter) - Harmonize itrace's synthesized callchains with the existing --max-stack tool option. (Adrian Hunter) - Allow time to be displayed in nanoseconds in 'perf script'. (Adrian Hunter) - Fix potential infinite loop when handling Intel PT timestamps. (Adrian Hunter) - Slighly improve Intel PT debug logging. (Adrian Hunter) - Warn when AUX data has been lost, just like when processing PERF_RECORD_LOST. (Adrian Hunter) - Further document export-to-postgresql.py script. (Adrian Hunter) - Add option to synthesize branch stack from auxtrace data. (Adrian Hunter) Misc notable changes: - Switch the default callchain output mode to 'graph,0.5,caller', to make it look like the default for other tools, reducing the learning curve for people used to 'caller' based viewing. (Arnaldo Carvalho de Melo) - various call chain usability enhancements. (Namhyung Kim) - Introduce the 'P' event modifier, meaning 'max precision level, please', i.e.: $ perf record -e cycles:P usleep 1 Is now similar to: $ perf record usleep 1 Useful, for instance, when specifying multiple events. (Jiri Olsa) - Add 'socket' sort entry, to sort by the processor socket in 'perf top' and 'perf report'. (Kan Liang) - Introduce --socket-filter to 'perf report', for filtering by processor socket.

atomic: remove all traces of READ_ONCE_CTRL() and atomic*_read_ctrl()
This seems to be a mis-reading of how alpha memory ordering works, and is not backed up by the alpha architecture manual. The helper functions don't do anything special on any other architectures, and the arguments that support them being safe on other architectures also argue that they are safe on alpha. Basically, the "control dependency" is between a previous read and a subsequent write that is dependent on the value read. Even if the subsequent write is actually done speculatively, there is no way that such a speculative write could be made visible to other cpu's until it has been committed, which requires validating the speculation. Note that most weakely ordered architectures (very much including alpha) do not guarantee any ordering relationship between two loads that depend on each other on a control dependency: read A if (val == 1) read B because the conditional may be predicted, and the "read B" may be speculatively moved up to before reading the value A. So we require the user to insert a smp_rmb() between the two accesses to be correct: read A; if (A == 1) smp_rmb() read B Alpha is further special in that it can break that ordering even if the *address* of B depends on the read of A, because the cacheline that is read later may be stale unless you have a memory barrier in between the pointer read and the read of the value behind a pointer: read ptr read offset(ptr) whereas all other weakly ordered architectures guarantee that the data dependency (as opposed to just a control dependency) will order the two accesses. As a result, alpha needs a "smp_read_barrier_depends()" in between those two reads for them to be ordered. The coontrol dependency that "READ_ONCE_CTRL()" and "atomic_read_ctrl()" had was a control dependency to a subsequent *write*, however, and nobody can finalize such a subsequent write without having actually done the read. And were you to write such a value to a "stale" cacheline (the way the unordered reads came to be), that would seem to lose the write entirely. So the things that make alpha able to re-order reads even more aggressively than other weak architectures do not seem to be relevant for a subsequent write. Alpha memory ordering may be strange, but there's no real indication that it is *that* strange. Also, the alpha architecture reference manual very explicitly talks about the definition of "Dependence Constraints" in section 5.6.1.7, where a preceding read dominates a subsequent write. Such a dependence constraint admittedly does not impose a BEFORE (alpha architecture term for globally visible ordering), but it does guarantee that there can be no "causal loop". I don't see how you could avoid such a loop if another cpu could see the stored value and then impact the value of the first read. Put another way: the read and the write could not be seen as being out of order wrt other cpus. So I do not see how these "x_ctrl()" functions can currently be necessary. I may have to eat my words at some point, but in the absense of clear proof that alpha actually needs this, or indeed even an explanation of how alpha could _possibly_ need it, I do not believe these functions are called for. And if it turns out that alpha really _does_ need a barrier for this case, that barrier still should not be "smp_read_barrier_depends()". We'd have to make up some new speciality barrier just for alpha, along with the documentation for why it really is necessary.

"nlb_pr_rq" can't be more than u32 because "len" is a u32. Later we truncate it to u32 anyway when we calculate min_t(). Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Jens Axboe <axboe@fb.com> |

Pull ARM updates from Russell King: "In this ARM merge, we remove more lines than we add. Changes include: - Enable imprecise aborts early, so that bus errors aren't masked until later in the boot. This has the side effect that boot loaders which provoke these aborts can cause the kernel to crash early in boot, so we install a handler to report this event around the site where these are enabled. - Remove the buggy but impossible to enable cmpxchg syscall code. - Add unwinding annotations to some assembly code. - Add support for atomic half-word exchange for ARMv6k+. - Reduce ioremap() alignment for SMP/LPAE cases where we don't need the large alignment. - Addition of an "optimal" 3G configuration for systems with 1G of RAM. - Increase vmalloc space by 128M. - Constify some SMP operations structures, which have never been writable. - Improve ARMs dma_mmap() support for mapping DMA coherent mappings into userspace. - Fix to the NMI backtrace code in the IPI case on ARM where the failing CPU gets stuck for 10s waiting for its own IPI to be delivered. - Removal of legacy PM support from the AMBA bus driver. - Another fix for the previous fix of vdsomunge" * 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (23 commits) ARM: 8449/1: fix bug in vdsomunge swab32 macro arm: add missing of_node_put ARM: 8447/1: catch pending imprecise abort on unmask ARM: 8446/1: amba: Remove unused callbacks for legacy system PM ARM: 8443/1: Adding support for atomic half word exchange ARM: clean up TWD after previous patch ARM: 8441/2: twd: Don't set CLOCK_EVT_FEAT_C3STOP unconditionally ARM: 8440/1: remove obsolete documentation ARM: make highpte an expert option ARM: 8433/1: add a VMSPLIT_3G_OPT config option ARM: 8439/1: Fix backtrace generation when IPI is masked ARM: 8428/1: kgdb: Fix registers on sleeping tasks ARM: 8427/1: dma-mapping: add support for offset parameter in dma_mmap() ARM: 8426/1: dma-mapping: add missing range check in dma_mmap() ARM: remove user cmpxchg syscall ARM: 8438/1: Add unwinding to __clear_user_std() ARM: 8436/1: hw_breakpoint: remove unnecessary header ARM: 8434/2: Revert "7655/1: smp_twd: make twd_local_timer_of_register() no-op for nosmp" ARM: 8432/1: move VMALLOC_END from 0xff000000 to 0xff800000 ARM: 8430/1: use default ioremap alignment for SMP or LPAE ... |

switchdev: respect SKIP_EOPNOTSUPP flag in case there is no recursion
Caller passing down the SKIP_EOPNOTSUPP switchdev flag expects that
-EOPNOTSUPP cannot be returned. But in case of direct op call without
recurtion, this may happen. So fix this by checking it always on the
end of __switchdev_port_attr_set function.
Fixes:
