      dax: relocate some dax functions · e30331ff
      Ross Zwisler authored
      dax_load_hole() will soon need to call dax_insert_mapping_entry(), so it
      needs to be moved lower in dax.c so the definition exists.
      
      dax_wake_mapping_entry_waiter() will soon be removed from dax.h and be
      made static to dax.c, so we need to move its definition above all its
      callers.

      mm: add vm_insert_mixed_mkwrite() · b2770da6
      Ross Zwisler authored
      When servicing mmap() reads from file holes the current DAX code
      allocates a page cache page of all zeroes and places the struct page
      pointer in the mapping->page_tree radix tree.  This has three major
      drawbacks:
      
      1) It consumes memory unnecessarily. For every 4k page that is read via
         a DAX mmap() over a hole, we allocate a new page cache page. This
         means that if you read 1GiB worth of pages, you end up using 1GiB of
         zeroed memory.
      
      2) It is slower than using a common zero page because each page fault
         has more work to do. Instead of just inserting a common zero page we
         have to allocate a page cache page, zero it, and then insert it.
      
      3) The fact that we had to check for both DAX exceptional entries and
         for page cache pages in the radix tree made the DAX code more
         complex.
      
      This series solves these issues by following the lead of the DAX PMD
      code and using a common 4k zero page instead.  This reduces memory usage
      and decreases latencies for some workloads, and it simplifies the DAX
      code, removing over 100 lines in total.
      
      This patch (of 5):
      
      To be able to use the common 4k zero page in DAX we need to have our PTE
      fault path look more like our PMD fault path where a PTE entry can be
      marked as dirty and writeable as it is first inserted rather than
      waiting for a follow-up dax_pfn_mkwrite() => finish_mkwrite_fault()
      call.
      
      Right now we can rely on having a dax_pfn_mkwrite() call because we can
      distinguish between these two cases in do_wp_page():
      
      	case 1: 4k zero page => writable DAX storage
      	case 2: read-only DAX storage => writeable DAX storage
      
      This distinction is made by via vm_normal_page().  vm_normal_page()
      returns false for the common 4k zero page, though, just as it does for
      DAX ptes.  Instead of special casing the DAX + 4k zero page case we will
      simplify our DAX PTE page fault sequence so that it matches our DAX PMD
      sequence, and get rid of the dax_pfn_mkwrite() helper.  We will instead
      use dax_iomap_fault() to handle write-protection faults.
      
      This means that insert_pfn() needs to follow the lead of
      insert_pfn_pmd() and allow us to pass in a 'mkwrite' flag.  If 'mkwrite'
      is set insert_pfn() will do the work that was previously done by
      wp_page_reuse() as part of the dax_pfn_mkwrite() call path.

      Pull power management updates from Rafael Wysocki:
       "This time (again) cpufreq gets the majority of changes which mostly
        are driver updates (including a major consolidation of intel_pstate),
        some schedutil governor modifications and core cleanups.
      
        There also are some changes in the system suspend area, mostly related
        to diagnostics and debug messages plus some renames of things related
        to suspend-to-idle. One major change here is that suspend-to-idle is
        now going to be preferred over S3 on systems where the ACPI tables
        indicate to do so and provide requsite support (the Low Power Idle S0
        _DSM in particular). The system sleep documentation and the tools
        related to it are updated too.
      
        The rest is a few cpuidle changes (nothing major), devfreq updates,
        generic power domains (genpd) framework updates and a few assorted
        modifications elsewhere.
      
        Specifics:
      
         - Drop the P-state selection algorithm based on a PID controller from
           intel_pstate and make it use the same P-state selection method
           (based on the CPU load) for all types of systems in the active mode
           (Rafael Wysocki, Srinivas Pandruvada).
      
         - Rework the cpufreq core and governors to make it possible to take
           cross-CPU utilization updates into account and modify the schedutil
           governor to actually do so (Viresh Kumar).
      
         - Clean up the handling of transition latency information in the
           cpufreq core and untangle it from the information on which drivers
           cannot do dynamic frequency switching (Viresh Kumar).
      
         - Add support for new SoCs (MT2701/MT7623 and MT7622) to the mediatek
           cpufreq driver and update its DT bindings (Sean Wang).
      
         - Modify the cpufreq dt-platdev driver to autimatically create
           cpufreq devices for the new (v2) Operating Performance Points (OPP)
           DT bindings and update its whitelist of supported systems (Viresh
           Kumar, Shubhrajyoti Datta, Marc Gonzalez, Khiem Nguyen, Finley
           Xiao).
      
         - Add support for Ux500 to the cpufreq-dt driver and drop the
           obsolete dbx500 cpufreq driver (Linus Walleij, Arnd Bergmann).
      
         - Add new SoC (R8A7795) support to the cpufreq rcar driver (Khiem
           Nguyen).
      
         - Fix and clean up assorted issues in the cpufreq drivers and core
           (Arvind Yadav, Christophe Jaillet, Colin Ian King, Gustavo Silva,
           Julia Lawall, Leonard Crestez, Rob Herring, Sudeep Holla).
      
         - Update the IO-wait boost handling in the schedutil governor to make
           it less aggressive (Joel Fernandes).
      
         - Rework system suspend diagnostics to make it print fewer messages
           to the kernel log by default, add a sysfs knob to allow more
           suspend-related messages to be printed and add Low Power S0 Idle
           constraints checks to the ACPI suspend-to-idle code (Rafael
           Wysocki, Srinivas Pandruvada).
      
         - Prefer suspend-to-idle over S3 on ACPI-based systems with the
           ACPI_FADT_LOW_POWER_S0 flag set and the Low Power Idle S0 _DSM
           interface present in the ACPI tables (Rafael Wysocki).
      
         - Update documentation related to system sleep and rename a number of
           items in the code to make it cleare that they are related to
           suspend-to-idle (Rafael Wysocki).
      
         - Export a variable allowing device drivers to check the target
           system sleep state from the core system suspend code (Florian
           Fainelli).
      
         - Clean up the cpuidle subsystem to handle the polling state on x86
           in a more straightforward way and to use %pOF instead of full_name
           (Rafael Wysocki, Rob Herring).
      
         - Update the devfreq framework to fix and clean up a few minor issues
           (Chanwoo Choi, Rob Herring).
      
         - Extend diagnostics in the generic power domains (genpd) framework
           and clean it up slightly (Thara Gopinath, Rob Herring).
      
         - Fix and clean up a couple of issues in the operating performance
           points (OPP) framework (Viresh Kumar, Waldemar Rymarkiewicz).
      
         - Add support for RV1108 to the rockchip-io Adaptive Voltage Scaling
           (AVS) driver (David Wu).
      
         - Fix the usage of notifiers in CPU power management on some
           platforms (Alex Shi).
      
         - Update the pm-graph system suspend/hibernation and boot profiling
           utility (Todd Brandt).
      
         - Make it possible to run the cpupower utility without CPU0 (Prarit

       "This is the bulk of the GPIO changes for the v4.14 cycle.
      
        Not so much changes this time, phew. David Daney and Bartosz
        Golaszewski did all the really interesting work in infrastructure
        improvement across GPIO and IRQ core, hats off for them and to tglx
        and Marc Z for general help with these patch sets.
      
        Core changes:
      
         - Allow the GPIO irqchip to allocate IRQs dynamically. This is an
           important change on systems where only a restricted number of IRQs,
           lesser than the number of GPIO lines, can be utilized. Now we can
           allocate these on a first-come-first-served basis instead of
           hogging up valuable IRQ lines.
      
         - Serious fix-up of the kerneldoc documentation and inclusion into
           the kerneldoc builds.
      
         - Pulled in the IRQ simulator from the IRQ core tree and use this in
           the GPIO mockup driver for exhaustive testing of interrupt
           abilities.
      
        New drivers:
      
         - New driver for ThunderX and OCTEON-TX. This is especially
           interesting as it picks up improvements from the IRQ core that
           allow us to handle fasteoi ACKs upwards in a hierarchy when there
           are IRQ flag latches on several levels in a hierarchy. Very
           interesting work here.
      
         - New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
      
        Misc:
      
         - Several fixes and improvements for Xilinx Zynq GPIO.
      
         - Support an enablement GPIO for the 74x164 GPIO.
      
         - Switch a bunch of chips to use devres to allocate irq descriptors.
      
         - A bunch of constification fixes"

        There are just a few bigger changes (new drivers mostly) and then a
        lot of small patches all over the place.
      
        Core changes:
         - Decision to wrap the sleep mode of the Spreadtrum and in the future
           others into a specially tagged state. The generic DT bindings and
           the new Spreadtrum driver conforms to this. Others should be moved
           over if possible.
      
        New drivers:
         - Spreadtrum SoCs especially the SC9860 SoC.
         - Storlink/Cortina Gemini 3512 and 3516 SoCs.

      Pull arm64 updates from Catalin Marinas:
      
       - VMAP_STACK support, allowing the kernel stacks to be allocated in the
         vmalloc space with a guard page for trapping stack overflows. One of
         the patches introduces THREAD_ALIGN and changes the generic
         alloc_thread_stack_node() to use this instead of THREAD_SIZE (no
         functional change for other architectures)
      
       - Contiguous PTE hugetlb support re-enabled (after being reverted a
         couple of times). We now have the semantics agreed in the generic mm
         layer together with API improvements so that the architecture code
         can detect between contiguous and non-contiguous huge PTEs
      
       - Initial support for persistent memory on ARM: DC CVAP instruction
         exposed to user space (HWCAP) and the in-kernel pmem API implemented
      
       - raid6 improvements for arm64: faster algorithm for the delta syndrome
         and implementation of the recovery routines using Neon
      
       - FP/SIMD refactoring and removal of support for Neon in interrupt
         context. This is in preparation for full SVE support
      
       - PTE accessors converted from inline asm to cmpxchg so that we can use
         LSE atomics if available (ARMv8.1)
      
       - Perf support for Cortex-A35 and A73

        Monitoring (CQM) facility.
      
        The existing CQM support was duct taped into perf with a lot of issues
        and the attempts to fix those turned out to be incomplete and
        horrible.
      
        After lengthy discussions it was decided to integrate the CQM support
        into the Resource Director Technology (RDT) facility, which is the
        obvious choise as in hardware CQM is part of RDT. This allowed to add
        Memory Bandwidth Monitoring support on top.
      
        As a result the mechanisms for allocating cache/memory bandwidth and
        the corresponding monitoring mechanisms are integrated into a single
        management facility with a consistent user interface"

      Linus Torvalds authored
      Pull x86 mm changes from Ingo Molnar:
       "PCID support, 5-level paging support, Secure Memory Encryption support
      
        The main changes in this cycle are support for three new, complex
        hardware features of x86 CPUs:
      
         - Add 5-level paging support, which is a new hardware feature on
           upcoming Intel CPUs allowing up to 128 PB of virtual address space
           and 4 PB of physical RAM space - a 512-fold increase over the old
           limits. (Supercomputers of the future forecasting hurricanes on an
           ever warming planet can certainly make good use of more RAM.)
      
           Many of the necessary changes went upstream in previous cycles,
           v4.14 is the first kernel that can enable 5-level paging.
      
           This feature is activated via CONFIG_X86_5LEVEL=y - disabled by
           default.
      
           (By Kirill A. Shutemov)
      
         - Add 'encrypted memory' support, which is a new hardware feature on
           upcoming AMD CPUs ('Secure Memory Encryption', SME) allowing system
           RAM to be encrypted and decrypted (mostly) transparently by the
           CPU, with a little help from the kernel to transition to/from
           encrypted RAM. Such RAM should be more secure against various
           attacks like RAM access via the memory bus and should make the
           radio signature of memory bus traffic harder to intercept (and
           decrypt) as well.
      
           This feature is activated via CONFIG_AMD_MEM_ENCRYPT=y - disabled
           by default.
      
           (By Tom Lendacky)
      
         - Enable PCID optimized TLB flushing on newer Intel CPUs: PCID is a
           hardware feature that attaches an address space tag to TLB entries
           and thus allows to skip TLB flushing in many cases, even if we
           switch mm's.
      
           (By Andy Lutomirski)
      
        All three of these features were in the works for a long time, and
        it's coincidence of the three independent development paths that they
        are all enabled in v4.14 at once"
