s390: correct some inline assembly constraints
Inline assembly code changed in this patch should really use "Q" constraint "Memory reference without index register and with short displacement". The kernel does not compile with kasan support enabled otherwise (due to stack instrumentation).

s390: remove all code using the access register mode
The vdso code for the getcpu() and the clock_gettime() call use the access register mode to access the per-CPU vdso data page with the current code. An alternative to the complicated AR mode is to use the secondary space mode. This makes the vdso faster and quite a bit simpler. The downside is that the uaccess code has to be changed quite a bit. Which instructions are used depends on the machine and what kind of uaccess operation is requested. The instruction dictates which ASCE value needs to be loaded into %cr1 and %cr7. The different cases: * User copy with MVCOS for z10 and newer machines The MVCOS instruction can copy between the primary space (aka user) and the home space (aka kernel) directly. For set_fs(KERNEL_DS) the kernel ASCE is loaded into %cr1. For set_fs(USER_DS) the user space is already loaded in %cr1. * User copy with MVCP/MVCS for older machines To be able to execute the MVCP/MVCS instructions the kernel needs to switch to primary mode. The control register %cr1 has to be set to the kernel ASCE and %cr7 to either the kernel ASCE or the user ASCE dependent on set_fs(KERNEL_DS) vs set_fs(USER_DS). * Data access in the user address space for strnlen / futex To use "normal" instruction with data from the user address space the secondary space mode is used. The kernel needs to switch to primary mode, %cr1 has to contain the kernel ASCE and %cr7 either the user ASCE or the kernel ASCE, dependent on set_fs. To load a new value into %cr1 or %cr7 is an expensive operation, the kernel tries to be lazy about it. E.g. for multiple user copies in a row with MVCP/MVCS the replacement of the vdso ASCE in %cr7 with the user ASCE is done only once. On return to user space a CPU bit is checked that loads the vdso ASCE again. To enable and disable the data access via the secondary space two new functions are added, enable_sacf_uaccess and disable_sacf_uaccess. The fact that a context is in secondary space uaccess mode is stored in the mm_segment_t value for the task. The code of an interrupt may use set_fs as long as it returns to the previous state it got with get_fs with another call to set_fs. The code in finish_arch_post_lock_switch simply has to do a set_fs with the current mm_segment_t value for the task. For CPUs with MVCOS: CPU running in | %cr1 ASCE | %cr7 ASCE | --------------------------------------|-----------|-----------| user space | user | vdso | kernel, USER_DS, normal-mode | user | vdso | kernel, USER_DS, normal-mode, lazy | user | user | kernel, USER_DS, sacf-mode | kernel | user | kernel, KERNEL_DS, normal-mode | kernel | vdso | kernel, KERNEL_DS, normal-mode, lazy | kernel | kernel | kernel, KERNEL_DS, sacf-mode | kernel | kernel | For CPUs without MVCOS: CPU running in | %cr1 ASCE | %cr7 ASCE | --------------------------------------|-----------|-----------| user space | user | vdso | kernel, USER_DS, normal-mode | user | vdso | kernel, USER_DS, normal-mode lazy | kernel | user | kernel, USER_DS, sacf-mode | kernel | user | kernel, KERNEL_DS, normal-mode | kernel | vdso | kernel, KERNEL_DS, normal-mode, lazy | kernel | kernel | kernel, KERNEL_DS, sacf-mode | kernel | kernel | The lines with "lazy" refer to the state after a copy via the secondary space with a delayed reload of %cr1 and %cr7. There are three hardware address spaces that can cause a DAT exception, primary, secondary and home space. The exception can be related to four different fault types: user space fault, vdso fault, kernel fault, and the gmap faults. Dependent on the set_fs state and normal vs. sacf mode there are a number of fault combinations: 1) user address space fault via the primary ASCE 2) gmap address space fault via the primary ASCE 3) kernel address space fault via the primary ASCE for machines with MVCOS and set_fs(KERNEL_DS) 4) vdso address space faults via the secondary ASCE with an invalid address while running in secondary space in problem state 5) user address space fault via the secondary ASCE for user-copy based on the secondary space mode, e.g. futex_ops or strnlen_user 6) kernel address space fault via the secondary ASCE for user-copy with secondary space mode with set_fs(KERNEL_DS) 7) kernel address space fault via the primary ASCE for user-copy with secondary space mode with set_fs(USER_DS) on machines without MVCOS. 8) kernel address space fault via the home space ASCE Replace user_space_fault() with a new function get_fault_type() that can distinguish all four different fault types. With these changes the futex atomic ops from the kernel and the strnlen_user will get a little bit slower, as well as the old style uaccess with MVCP/MVCS. All user accesses based on MVCOS will be as fast as before. On the positive side, the user space vdso code is a lot faster and Linux ceases to use the complicated AR mode.

s390/mm,kvm: improve detection of KVM guest faults
The identification of guest fault currently relies on the PF_VCPU flag. This is set in guest_entry_irqoff and cleared in guest_exit_irqoff. Both functions are called by __vcpu_run, the PF_VCPU flag is set for quite a lot of kernel code outside of the guest execution. Replace the PF_VCPU scheme with the PIF_GUEST_FAULT in the pt_regs and make the program check handler code in entry.S set the bit only for exception that occurred between the .Lsie_gmap and .Lsie_done labels.

The most noticeable change is probably the relocation of the OPP (Operating Performance Points) framework to its own directory under drivers/ as it has grown big enough for that. Also Viresh is now going to maintain it and send pull requests for it to me, so you will see this change in the git history going forward (but still not right now). Another noticeable set of changes is the modifications of the PM core, the PCI subsystem and the ACPI PM domain to allow of more integration between system-wide suspend/resume and runtime PM. For now it's just a way to avoid resuming devices from runtime suspend unnecessarily during system suspend (if the driver sets a flag to indicate its readiness for that) and in the works is an analogous mechanism to allow devices to stay suspended after system resume. In addition to that, we have some changes related to supporting frequency-invariant CPU utilization metrics in the scheduler and in the schedutil cpufreq governor on ARM and changes to add support for device performance states to the generic power domains (genpd) framework. The rest is mostly fixes and cleanups of various sorts. Specifics: - Relocate the OPP (Operating Performance Points) framework to its own directory under drivers/ and add support for power domain performance states to it (Viresh Kumar). - Modify the PM core, the PCI bus type and the ACPI PM domain to support power management driver flags allowing device drivers to specify their capabilities and preferences regarding the handling of devices with enabled runtime PM during system suspend/resume and clean up that code somewhat (Rafael Wysocki, Ulf Hansson). - Add frequency-invariant accounting support to the task scheduler on ARM and ARM64 (Dietmar Eggemann). - Fix PM QoS device resume latency framework to prevent "no restriction" requests from overriding requests with specific requirements and drop the confusing PM_QOS_FLAG_REMOTE_WAKEUP device PM QoS flag (Rafael Wysocki). - Drop legacy class suspend/resume operations from the PM core and drop legacy bus type suspend and resume callbacks from ARM/locomo (Rafael Wysocki). - Add min/max frequency support to devfreq and clean it up somewhat (Chanwoo Choi). - Rework wakeup support in the generic power domains (genpd) framework and update some of its users accordingly (Geert Uytterhoeven). - Convert timers in the PM core to use timer_setup() (Kees Cook). - Add support for exposing the SLP_S0 (Low Power S0 Idle) residency counter based on the LPIT ACPI table on Intel platforms (Srinivas Pandruvada). - Add per-CPU PM QoS resume latency support to the ladder cpuidle governor (Ramesh Thomas). - Fix a deadlock between the wakeup notify handler and the notifier removal in the ACPI core (Ville Syrjälä). - Fix a cpufreq schedutil governor issue causing it to use stale cached frequency values sometimes (Viresh Kumar). - Fix an issue in the system suspend core support code causing wakeup events detection to fail in some cases (Rajat Jain). - Fix the generic power domains (genpd) framework to prevent the PM core from using the direct-complete optimization with it as that is guaranteed to fail (Ulf Hansson). - Fix a minor issue in the cpuidle core and clean it up a bit (Gaurav Jindal, Nicholas Piggin). - Fix and clean up the intel_idle and ARM cpuidle drivers (Jason Baron, Len Brown, Leo Yan). - Fix a couple of minor issues in the OPP framework and clean it up (Arvind Yadav, Fabio Estevam, Sudeep Holla, Tobias Jordan). - Fix and clean up some cpufreq drivers and fix a minor issue in the cpufreq statistics code (Arvind Yadav, Bhumika Goyal, Fabio Estevam, Gautham Shenoy, Gustavo Silva, Marek Szyprowski, Masahiro Yamada, Robert Jarzmik, Zumeng Chen). - Fix minor issues in the system suspend and hibernation core, in power management documentation and in the AVS (Adaptive Voltage Scaling) framework (Helge Deller, Himanshu Jha, Joe Perches, Rafael Wysocki). - Fix some issues in the cpupower utility and document that Shuah Khan is going to maintain it going forward (Prarit Bhargava, Shuah Khan)" * tag 'pm-4.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (88 commits) tools/power/cpupower: add libcpupower.so.0.0.1 to .gitignore tools/power/cpupower: Add 64 bit library detection intel_idle: Graceful probe failure when MWAIT is disabled cpufreq: schedutil: Reset cached_raw_freq when not in sync with next_freq freezer: Fix typo in freezable_schedule_timeout() comment PM / s2idle: Clear the events_check_enabled flag cpufreq: stats: Handle the case when trans_table goes beyond PAGE_SIZE cpufreq: arm_big_little: make cpufreq_arm_bL_ops structures const cpufreq: arm_big_little: make function arguments and structure pointer const cpuidle: Avoid assignment in if () argument cpuidle: Clean up cpuidle_enable_device() error handling a bit ACPI / PM: Fix acpi_pm_notifier_lock vs flush_workqueue() deadlock PM / Domains: Fix genpd to deal with drivers returning 1 from ->prepare() cpuidle: ladder: Add per CPU PM QoS resume latency support PM / QoS: Fix device resume latency framework PM / domains: Rework governor code to be more consistent PM / Domains: Remove gpd_dev_ops.active_wakeup() callback soc: rockchip: power-domain: Use GENPD_FLAG_ACTIVE_WAKEUP soc: mediatek: Use GENPD_FLAG_ACTIVE_WAKEUP ARM: shmobile: pm-rmobile: Use GENPD_FLAG_ACTIVE_WAKEUP ... |

x86 / CPU: Avoid unnecessary IPIs in arch_freq_get_on_cpu()
Even though aperfmperf_snapshot_khz() caches the samples.khz value to return if called again in a sufficiently short time, its caller, arch_freq_get_on_cpu(), still uses smp_call_function_single() to run it which may allow user space to trigger an IPI storm by reading from the scaling_cur_freq cpufreq sysfs file in a tight loop. To avoid that, move the decision on whether or not to return the cached samples.khz value to arch_freq_get_on_cpu(). This change was part of commit |

Merge branch 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull x86 APIC updates from Thomas Gleixner: "This update provides a major overhaul of the APIC initialization and vector allocation code: - Unification of the APIC and interrupt mode setup which was scattered all over the place and was hard to follow. This also distangles the timer setup from the APIC initialization which brings a clear separation of functionality. Great detective work from Dou Lyiang! - Refactoring of the x86 vector allocation mechanism. The existing code was based on nested loops and rather convoluted APIC callbacks which had a horrible worst case behaviour and tried to serve all different use cases in one go. This led to quite odd hacks when supporting the new managed interupt facility for multiqueue devices and made it more or less impossible to deal with the vector space exhaustion which was a major roadblock for server hibernation. Aside of that the code dealing with cpu hotplug and the system vectors was disconnected from the actual vector management and allocation code, which made it hard to follow and maintain. Utilizing the new bitmap matrix allocator core mechanism, the new allocator and management code consolidates the handling of system vectors, legacy vectors, cpu hotplug mechanisms and the actual allocation which needs to be aware of system and legacy vectors and hotplug constraints into a single consistent entity. This has one visible change: The support for multi CPU targets of interrupts, which is only available on a certain subset of CPUs/APIC variants has been removed in favour of single interrupt targets. A proper analysis of the multi CPU target feature revealed that there is no real advantage as the vast majority of interrupts end up on the CPU with the lowest APIC id in the set of target CPUs anyway. That change was agreed on by the relevant folks and allowed to simplify the implementation significantly and to replace rather fragile constructs like the vector cleanup IPI with straight forward and solid code. Furthermore this allowed to cleanly separate the allocation details for legacy, normal and managed interrupts: * Legacy interrupts are not longer wasting 16 vectors unconditionally * Managed interrupts have now a guaranteed vector reservation, but the actual vector assignment happens when the interrupt is requested. It's guaranteed not to fail. * Normal interrupts no longer allocate vectors unconditionally when the interrupt is set up (IO/APIC init or MSI(X) enable). The mechanism has been switched to a best effort reservation mode. The actual allocation happens when the interrupt is requested. Contrary to managed interrupts the request can fail due to vector space exhaustion, but drivers must handle a fail of request_irq() anyway. When the interrupt is freed, the vector is handed back as well. This solves a long standing problem with large unconditional vector allocations for a certain class of enterprise devices which prevented server hibernation due to vector space exhaustion when the unused allocated vectors had to be migrated to CPU0 while unplugging all non boot CPUs. The code has been equipped with trace points and detailed debugfs information to aid analysis of the vector space" * 'x86-apic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (60 commits) x86/vector/msi: Select CONFIG_GENERIC_IRQ_RESERVATION_MODE PCI/MSI: Set MSI_FLAG_MUST_REACTIVATE in core code genirq: Add config option for reservation mode x86/vector: Use correct per cpu variable in free_moved_vector() x86/apic/vector: Ignore set_affinity call for inactive interrupts x86/apic: Fix spelling mistake: "symmectic" -> "symmetric" x86/apic: Use dead_cpu instead of current CPU when cleaning up ACPI/init: Invoke early ACPI initialization earlier x86/vector: Respect affinity mask in irq descriptor x86/irq: Simplify hotplug vector accounting x86/vector: Switch IOAPIC to global reservation mode x86/vector/msi: Switch to global reservation mode x86/vector: Handle managed interrupts proper x86/io_apic: Reevaluate vector configuration on activate() iommu/amd: Reevaluate vector configuration on activate() iommu/vt-d: Reevaluate vector configuration on activate() x86/apic/msi: Force reactivation of interrupts at startup time x86/vector: Untangle internal state from irq_cfg x86/vector: Compile SMP only code conditionally x86/apic: Remove unused callbacks ... |

Can be used by tracing, perf as well if required. - A large number of timer setup conversions from Kees which got collected here because either maintainers requested so or they simply got ignored. As Kees pointed out already there are a few trivial merge conflicts and some redundant commits which was unavoidable due to the size of this conversion effort. - Avoid a redundant iteration in the timer wheel softirq processing. - Provide a mechanism to treat RTC implementations depending on their hardware properties, i.e. don't inflict the write at the 0.5 seconds boundary which originates from the PC CMOS RTC to all RTCs.

OpenRISC updates for v4.15
Small Things: - Move OpenRISC docs into Documentation and clean them up - Document previously undocumented devicetree bindings - Update the or1ksim dts to use stdout-path OpenRISC SMP support details: - First the "use shadow registers" and "define CPU_BIG_ENDIAN as true" get the architecture ready for SMP. - The "add 1 and 2 byte cmpxchg support" and "use qspinlocks and qrwlocks" add the SMP locking infrastructure as needed. Using the qspinlocks and qrwlocks as suggested by Peter Z while reviewing the original spinlocks implementation. - The "support for ompic" adds a new irqchip device which is used for IPI communication to support SMP. - The "initial SMP support" adds smp.c and makes changes to all of the necessary data-structures to be per-cpu. - The remaining patches are bug fixes and debug helpers which I wanted to keep separate from the "initial SMP support" in order to allow them to be reviewed on their own. This includes: - add cacheflush support to fix icache aliasing - fix initial preempt state for secondary cpu tasks - sleep instead of spin on secondary wait - support framepointers and STACKTRACE_SUPPORT - enable LOCKDEP_SUPPORT and irqflags tracing - timer sync: Add tick timer sync logic - fix possible deadlock in timer sync, pointed out by mips guys Note: the irqchip patch was reviewed with Marc and we agreed to push it together with these patches. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJaCaO/AAoJEMOzHC1eZifkwyUQAIwp5q242D5P0Mo8gvpmNZ7s Lc7XBe1+dahbW8OIh0b8XhufkwFHY614bnrDBAr8GOcbaOXgxk8LbhTmkwbFO9z7 fm5YKr7il0dunCWfw278sQcZsCRQ9sQkXIei0gJL/56Uq6dbJhIREcOgjHBjDW5r tblrbv70fPmTCP/7cw08y4QwXIAf+8zEhECJcDKqFZ2nhQkWQUd3BAppxdCOWSDa aV9qOa/koP9lAKg8aWOCwCuS+WK386KNCCowsTxpyWdl9tMWsebeBh1odxteKiiB KpAENfEvbjuYMWH3CQ+XdSDDdIdGnIP6l5KDzBkhF1USXwS7AlaMUpbPHcLXVRFi 1S2zcO9i6WfTnaDpNZc+L8oHqgyLUDJ6RgC6juLEmbfnCVmzNkLKCYa3d3JRI/oC 6qxpHYkLKWsJoOHDcs0fiMOLhkJZrzPYkIv0fW+uwTM10onxhm48fm6RNWuwqXWd 4FoH8ufqeACxWEotv6pcL7RUYrmX1gmvxby8CCHiUBIBoRM3bGmqTVvgX64nULgB QIn/74R3J6GDPKicHDcq8ZOnMWvE6nbpXXbX73PqjXMf80HVjejV3Fg2su8m7LR0 +ni1ndKYB3V+t0+m1m5eMvpKMQ2HrMIMdx0M4xL+Z0fT8B3lcZWpb4wBsG7E+C49 pyf9xEk34Fe7HR+7KBO9 =euP7 -----END PGP SIGNATURE----- Merge tag 'for-linus' of git://github.com/openrisc/linux Pull OpenRISC updates from Stafford Horne: "The OpenRISC work is a bit more interesting this time, adding SMP support and a few general cleanups.

/proc/module: fix building without kallsyms
As reported by kernelci and other build bots, we now get a link
failure without CONFIG_KALLSYMS:
module.c:(.text+0xf2c): undefined reference to `kallsyms_show_value'
This adds a dummy helper with the same name that can be used
for compilation. It's not entirely clear to me what this
should return for !CONFIG_KALLSYMS, I picked an unconditional
'false', which leads to the module address being unavailable
to user space.
Link: https://kernelci.org/build/mainline/branch/master/kernel/v4.14-5-g516fb7f2e73d/

kallsyms: fix building without printk
Building kallsyms fails without CONFIG_PRINTK due to a missing
declaration:
kernel/kallsyms.c: In function 'kallsyms_show_value':
kernel/kallsyms.c:670:10: error: 'kptr_restrict' undeclared (first use in this function); did you mean 'keyring_restrict'?
This moves the declaration outside of the #ifdef guard, the definition
is already available without CONFIG_PRINTK.

regmap: Updates for v4.15
After several quiet kernel releases we've got a couple of new features in regmap, support for using hwspinlocks as the lock for the internal data structures and a helper for polling on regmap_fields. The Kconfig dependencies on hwspinlocks were annoyingly difficult to squash between things behaving surprisingly and randconfig, I could've squashed those commits down but might've have caused hassle with other trees trying to use the new support. - Support for using a hwspinlock to protect the regmap. - An iopoll style helper for regmap_field. -----BEGIN PGP SIGNATURE----- iQFHBAABCgAxFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAloJkKUTHGJyb29uaWVA a2VybmVsLm9yZwAKCRAk1otyXVSH0Nr7B/9XaAdcoGg1FbcNeKrQN88VqGX8pU4W hcVMP4XdMxuBPmp/Rbkdkogvl8//MBGzn7jWnZBU59xkLnB0PfNB/JB5VdOrqT6w k+TdPNbs7s7cxTYubRBguhhEmC85gu2hiNCl+zlurPNBqHIhXXSVq+dNqlw4g4zI 0cm0bTxSCLOppoBPXQXFxa4fAXopNPWeAF7Cg8+oMl6er8p7iILkxFK31JuafKjZ 95RU0ikdmPHhV3OXrcE914hXnhFBM2VQ56z9BI84pwNONdRwWd10wRkoQ7zj4WDN qvNFY8mU/Bg6rHLI4Z2Ksj3zkLQs7VKBgdUL2dGPC/l3WElfFtF0sVkk =FBMj -----END PGP SIGNATURE----- Merge tag 'regmap-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap Pull regmap updates from Mark Brown: "After several quiet kernel releases we've got a couple of new features in regmap, support for using hwspinlocks as the lock for the internal data structures and a helper for polling on regmap_fields.
