      sh: sh7757: remove nonexistent GPIO_PT[JLNQ]7_RESV to fix pinctrl registration · d8ce38f6
      Geert Uytterhoeven authored
      Commit 3810e960 ("sh: modify pinmux for SH7757 2nd cut") renamed
      GPIO_PT[JLNQ]7 to GPIO_PT[JLNQ]7_RESV, and removed the existing users
      from the pinmux_pins[] array.
      
      However, pinmux_pins[] is initialized through PINMUX_GPIO(), using
      designated array initializers, where the GPIO_* enums serve as indices.
      Hence entries were not really removed, but replaced by (zero-filled)
      holes.  Such entries are treated as pin zero, which was registered
      before, thus leading to pinctrl registration failures, as seen on
      sh7722:
      
          sh-pfc pfc-sh7722: pin 0 already registered
          sh-pfc pfc-sh7722: error during pin registration
          sh-pfc pfc-sh7722: could not register: -22
          sh-pfc: probe of pfc-sh7722 failed with error -22
      
      Remove GPIO_PT[JLNQ]7_RESV from the enum to fix this.

      sh: sh7722: remove nonexistent GPIO_PTQ7 to fix pinctrl registration · b78412b8
      Geert Uytterhoeven authored
      Patch series "sh: sh7722/sh7757i/sh7264/sh7269: Fix pinctrl registration",
      v2.
      
      Magnus Damm reported that on sh7722/Migo-R, pinctrl registration fails
      with:
      
          sh-pfc pfc-sh7722: pin 0 already registered
          sh-pfc pfc-sh7722: error during pin registration
          sh-pfc pfc-sh7722: could not register: -22
          sh-pfc: probe of pfc-sh7722 failed with error -22
      
      pinmux_pins[] is initialized through PINMUX_GPIO(), using designated
      array initializers, where the GPIO_* enums serve as indices.  Apparently
      GPIO_PTQ7 was defined in the enum, but never used.  If enum values are
      defined, but never used, pinmux_pins[] contains (zero-filled) holes.
      Hence such entries are treated as pin zero, which was registered before,
      and pinctrl registration fails.
      
      I can't see how this ever worked, as at the time of commit f5e25ae5
      ("sh-pfc: Add sh7722 pinmux support"), pinmux_gpios[] in
      drivers/pinctrl/sh-pfc/pfc-sh7722.c already had the hole, and
      drivers/pinctrl/core.c already had the check.
      
      Some scripting revealed a few more broken drivers:
        - sh7757 has four holes, due to nonexistent GPIO_PT[JLNQ]7_RESV.
        - sh7264 and sh7269 define GPIO_PH[0-7], but don't use it with
          PINMUX_GPIO().
      
      Patch 1 fixes the issue on sh7722, and was tested.  Patches 3-4 should
      fix the issue on the other 3 SoCs, but was untested due to lack of
      hardware.
      
      This patch (of 4):
      
      On sh7722/Migo-R, pinctrl registration fails with:
      
          sh-pfc pfc-sh7722: pin 0 already registered
          sh-pfc pfc-sh7722: error during pin registration
          sh-pfc pfc-sh7722: could not register: -22
          sh-pfc: probe of pfc-sh7722 failed with error -22
      
      pinmux_pins[] is initialized through PINMUX_GPIO(), using designated array
      initializers, where the GPIO_* enums serve as indices.  As GPIO_PTQ7 is
      defined in the enum, but never used, pinmux_pins[] contains a
      (zero-filled) hole.  Hence this entry is treated as pin zero, which was
      registered before, and pinctrl registration fails.
      
      According to the datasheet, port PTQ7 does not exist.  Hence remove
      GPIO_PTQ7 from the enum to fix this.

      mm, hugetlb, soft_offline: save compound page order before page migration · 19bfbe22
      Alexandru Moise authored
      This fixes a bug in madvise() where if you'd try to soft offline a
      hugepage via madvise(), while walking the address range you'd end up,
      using the wrong page offset due to attempting to get the compound order
      of a former but presently not compound page, due to dissolving the huge
      page (since commit c3114a84: "mm: hugetlb: soft-offline: dissolve
      source hugepage after successful migration").
      
      As a result I ended up with all my free pages except one being offlined.

      include/linux/mm.h: fix typo in VM_MPX definition · fa87b91c
      Kirill A. Shutemov authored
      There's a typo in recent change of VM_MPX definition.  We want it to be
      VM_HIGH_ARCH_4, not VM_HIGH_ARCH_BIT_4.
      
      This bug does cause visible regressions.  In arch_vma_name the vmflags
      are tested against VM_MPX.  With the incorrect value of VM_MPX, a number
      of vmas (such as the stack) test positive and end up being marked as
      "[mpx]" in /proc/N/maps instead of their correct names.
      
      This confuses tools like rr which expect to be able to find familiar
      vmas.

           (slim) chance for split reads on some 32bit systems. Generic
           implementations are updated to disable irq when read size is larger
           than ulong size. This may have made some 32bit archs which can do

       "Here are a few small fixes for 4.14-rc4.
      
        The removal of DRIVER_ATTR() was almost completed by 4.14-rc1, but one
        straggler made it in through some other tree (odds are, one of
        mine...) So there's a simple removal of the last user, and then
        finally the macro is removed from the tree.
      
        There's a fix for old crazy udev instances that insist on reloading a
        module when it is removed from the kernel due to the new uevents for
        bind/unbind. This fixes the reported regression, hopefully some year
        in the future we can drop the workaround, once users update to the
        latest version, but I'm not holding my breath.
      
        And then there's a build fix for a linker warning, and a buffer
        overflow fix to match the PCI fixes you took through the PCI tree in
        the same area.

      Pull timer fixes from Thomas Gleixner:
       "This adds a new timer wheel function which is required for the
        conversion of the timer callback function from the 'unsigned long
        data' argument to 'struct timer_list *timer'. This conversion has two
        benefits:
      
         1) It makes struct timer_list smaller
      
         2) Many callers hand in a pointer to the timer or to the structure
            containing the timer, which happens via type casting both at setup
            and in the callback. This change gets rid of the typecasts.
      
        Once the conversion is complete, which is planned for 4.15, the old
        setup function and the intermediate typecast in the new setup function
        go away along with the data field in struct timer_list.
      
        Merging this now into mainline allows a smooth queueing of the actual
        conversion in the affected maintainer trees without creating
        dependencies"
