0e6e3c6f7c dt-bindings: gpio: dwapb: allow gpio-ranges
Allow the generic gpio-ranges property so GPIOs can be mapped to their
corresponding pin. This way control of GPIO on pins that are already used
by other peripherals can be denied and basic pinconf can be done on pin
controllers that support it.

65a828bab1 gpiolib: use a mutex to protect the list of GPIO devices
The global list of GPIO devices is never modified or accessed from
atomic context so it's fine to protect it using a mutex. Add a new
global lock dedicated to the gpio_devices list and use it whenever
accessing or modifying it.

f95fd4ac15 gpiolib: rename static functions that are called with the lock taken
Rename two functions that read or modify the global GPIO device list but
don't take the lock themselves (and need to be called with it already
acquired). Use the _unlocked() suffix which seems to be used quite
consistently across the kernel despite there also existing the _locked()
suffix for the same purpose.

9a9429b9ce gpio: ixp4xx: Handle clock output on pin 14 and 15
This makes it possible to provide basic clock output on pins
14 and 15. The clocks are typically used by random electronics,
not modeled in the device tree, so they just need to be provided
on request.

In order to not disturb old systems that require that the
hardware defaults are kept in the clock setting bits, we only
manipulate these if either device tree property is present.
Once we know a device needs one of the clocks we can set it
in the device tree.

5b2b1173a9 eventfs fixes:
- With the usage of simple_recursive_remove() recommended by Al Viro,
   the code should not be calling "d_invalidate()" itself. Doing so
   is causing crashes. The code was calling d_invalidate() on the race
   of trying to look up a file while the parent was being deleted.
   This was detected, and the added dentry was having d_invalidate() called
   on it, but the deletion of the directory was also calling d_invalidate()
   on that same dentry.
 
 - A fix to not free the eventfs_inode (ei) until the last dput() was called
   on its ei->dentry made the ei->dentry exist even after it was marked
   for free by setting the ei->is_freed. But code elsewhere still was
   checking if ei->dentry was NULL if ei->is_freed is set and would
   trigger WARN_ON if that was the case. That's no longer true and there
   should not be any warnings when it is true.
 
 - Use GFP_NOFS for allocations done under eventfs_mutex.
   The eventfs_mutex can be taken on file system reclaim, make sure
   that allocations done under that mutex do not trigger file system
   reclaim.
 
 - Clean up code by moving the taking of inode_lock out of the helper
   functions and into where they are needed, and not use the
   parameter to know to take it or not. It must always be held but
   some callers of the helper function have it taken when they were
   called.
 
 - Warn if the inode_lock is not held in the helper functions.
 
 - Warn if eventfs_start_creating() is called without a parent.
   As eventfs is underneath tracefs, all files created will have
   a parent (the top one will have a tracefs parent).
 
 Tracing update;
 
 - Add Mathieu Desnoyers as an official reviewer of the tracing sub system.

Pull parisc architecture fixes from Helge Deller:
 "This patchset fixes and enforces correct section alignments for the
  ex_table, altinstructions, parisc_unwind, jump_table and bug_table
  which are created by inline assembly.

  Due to not being correctly aligned at link & load time they can
  trigger unnecessarily the kernel unaligned exception handler at
  runtime. While at it, I switched the bug table to use relative
  addresses which reduces the size of the table by half on 64-bit.

  We still had the ENOSYM and EREMOTERELEASE errno symbols as left-overs
  from HP-UX, which now trigger build-issues with glibc. We can simply
  remove them.

  Most of the patches are tagged for stable kernel series.

  Summary:

   - Drop HP-UX ENOSYM and EREMOTERELEASE return codes to avoid glibc
     build issues

   - Fix section alignments for ex_table, altinstructions, parisc unwind
     table, jump_table and bug_table

Merge tag 'acpi-6.7-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI fixes from Rafael Wysocki:
 "These add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA and
  fix an ACPI processor idle issue leading to triple-faults in Xen HVM
  guests and an ACPI backlight driver issue that causes GPUs to
  misbehave while their children power is being fixed up.

  Specifics:

   - Avoid powering up GPUs while attempting to fix up power for their
     children (Hans de Goede)

   - Use raw_safe_halt() instead of safe_halt() in acpi_idle_play_dead()
     so as to avoid triple-falts during CPU online in Xen HVM guests due
     to the setting of the hardirqs_enabled flag in safe_halt() (David
     Woodhouse)

   - Add an ACPI IRQ override quirk for ASUS ExpertBook B1402CVA (Hans
     de Goede)"
