Pinmux_pins[] is initialized through PINMUX_GPIO(), using designated

values are defined, but never used, pinmux_pins[] contains (zero-filled)
holes.  Such entries are treated as pin zero, which was registered

Remove GPIO_PH[0-7] from the enum to fix this.

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

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.

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.

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

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"

Pull smp/hotplug fixes from Thomas Gleixner:
 "This addresses the fallout of the new lockdep mechanism which covers
  completions in the CPU hotplug code.

  The lockdep splats are false positives, but there is no way to
  annotate that reliably. The solution is to split the completions for
  CPU up and down, which requires some reshuffling of the failure
  rollback handling as well"

     explicit state characters for IDLE and PARKED so they wont be
     displayed as 'D' state which confuses tools"
