      vfs: fix flock compat thinko · b59eea55
      Linus Torvalds authored
      Michael Ellerman reported that commit 8c6657cb ("Switch flock
      copyin/copyout primitives to copy_{from,to}_user()") broke his
      networking on a bunch of PPC machines (64-bit kernel, 32-bit userspace).
      
      The reason is a brown-paper bug by that commit, which had the arguments
      to "copy_flock_fields()" in the wrong order, breaking the compat
      handling for file locking.  Apparently very few people run 32-bit user
      space on x86 any more, so the PPC people got the honor of noticing this
      "feature".
      
      Michael also sent a minimal diff that just changed the order of the
      arguments in that macro.
      
      This is not that minimal diff.
      
      This not only changes the order of the arguments in the macro, it also
      changes them to be pointers (to be consistent with all the other uses of
      those pointers), and makes the functions that do all of this also have
      the proper "const" attribution on the source pointers in order to make
      issues like that (using the source as a destination) be really obvious.

      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This is the bulk of GPIO changes for the v4.13 series.
      
        Some administrativa:
      
        I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
        driver coming in through this tree, along with a whole bunch of Exar
        8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
        where they are ACKed by Andy Shevchenko.
      
        Speaking about drivers/platform/* there is also a bunch of ACPI stuff
        coming through that route, again ACKed by Andy.
      
        The MCP23S08 changes are coming in here as well. You already have the
        commits in your tree, so this is just a result of sharing an immutable
        branch between pin control and GPIO.
      
        Core:
         - Export add/remove for lookup tables so that modules can export GPIO
           descriptor tables.
         - Handle GPIO sleep states: it is now possible to flag that a GPIO
           line may loose its state during suspend/resume of the system to
           save power. This is used in the Wolfson Micro Arizona driver.
         - ACPI-based GPIO was tightened up a lot around the edges.
         - Use bitmap_fill() to speed up a loop.
      
        New drivers:
         - Exar XRA1403 SPI-based GPIO.
         - MVEBU driver now supports Armada 7K and 8K.
         - LP87565 PMIC GPIO.
         - Renesas R-CAR R8A7743 (RZ/G1M).
         - The new IOT2040 8250 serial/GPIO also comes in through this
           changeset.
      
        Substantial driver changes:
         - Seriously fix the Exar 8250 GPIO portions to work.
         - The MCP23S08 was moved out to a pin control driver.
         - Convert MEVEBU to use regmap for register access.
         - Drop Vulcan support from the Broadcom driver.
         - Serious cleanup and improvement of the mockup driver, giving us a
           better test coverage.
      
        Misc:
         - Lots of janitorial clean up.
         - A bunch of documentation fixes"

      openrisc: explicitly include linux/bug.h in asm/fixmap.h · e687448c
      Tobias Klauser authored
      openrisc's asm/fixmap.h uses the BUG() and BUG_ON() macros but relies on
      implict inclusion of linux/bug.h which means that changes in other
      headers could break the build. Thus, add an explicit include.

      Linus Torvalds authored
      Pull libnvdimm updates from Dan Williams:
       "libnvdimm updates for the latest ACPI and UEFI specifications. This
        pull request also includes new 'struct dax_operations' enabling to
        undo the abuse of copy_user_nocache() for copy operations to pmem.
      
        The dax work originally missed 4.12 to address concerns raised by Al.
      
        Summary:
      
         - Introduce the _flushcache() family of memory copy helpers and use
           them for persistent memory write operations on x86. The
           _flushcache() semantic indicates that the cache is either bypassed
           for the copy operation (movnt) or any lines dirtied by the copy
           operation are written back (clwb, clflushopt, or clflush).
      
         - Extend dax_operations with ->copy_from_iter() and ->flush()
           operations. These operations and other infrastructure updates allow
           all persistent memory specific dax functionality to be pushed into
           libnvdimm and the pmem driver directly. It also allows dax-specific
           sysfs attributes to be linked to a host device, for example:
           /sys/block/pmem0/dax/write_cache
      
         - Add support for the new NVDIMM platform/firmware mechanisms
           introduced in ACPI 6.2 and UEFI 2.7. This support includes the v1.2
           namespace label format, extensions to the address-range-scrub
           command set, new error injection commands, and a new BTT
           (block-translation-table) layout. These updates support inter-OS
           and pre-OS compatibility.
      
         - Fix a longstanding memory corruption bug in nfit_test.
      
         - Make the pmem and nvdimm-region 'badblocks' sysfs files poll(2)
           capable.
      
         - Miscellaneous fixes and small updates across libnvdimm and the nfit
           driver.

       "The new features of this release:
      
         - Added TRACE_DEFINE_SIZEOF() which allows trace events that use

           that trace-cmd and perf can parse them correctly.
      
         - Some rework of the TRACE_DEFINE_ENUM() such that the above
           TRACE_DEFINE_SIZEOF() could reuse the same code.
      
         - Recording of tgid (Thread Group ID). This is similar to how task
           COMMs are recorded (cached at sched_switch), where it is in a table
           and used on output of the trace and trace_pipe files.
      
         - Have ":mod:<module>" be cached when written into set_ftrace_filter.
           Then the functions of the module will be traced at module load.

         - Better machine check handling for HV KVM
         - Ability to support guests with threads=2, 4 or 8 on POWER9
         - Fix for a race that could cause delayed recognition of signals
         - Fix for a bug where POWER9 guests could sleep with interrupts pending.
      
        ARM:
         - VCPU request overhaul
         - allow timer and PMU to have their interrupt number selected from userspace
         - workaround for Cavium erratum 30115
         - handling of memory poisonning
         - the usual crop of fixes and cleanups
      
        s390:
         - initial machine check forwarding
         - migration support for the CMMA page hinting information
         - cleanups and fixes
      
        x86:
         - nested VMX bugfixes and improvements
         - more reliable NMI window detection on AMD
         - APIC timer optimizations
      
        Generic:
         - VCPU request overhaul + documentation of common code patterns
         - kvm_stat improvements"
