Commit 08be8810 authored by Linus Torvalds's avatar Linus Torvalds

Merge tag 'acpi-4.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull ACPI updates from Rafael Wysocki:
 "These are some device enumeration code changes, updates of the AC and
  battery drivers to help them avoid attaching to devices that cannot be
  handled by them, new operation region driver for the Intel CHT Whiskey
  Cove PMIC, new sysfs entries for CPPC performance capabilities, a new
  _REV quirk blacklist entry and a couple of assorted minor fixes and
  cleanups.

  Specifics:

   - Update the core device enumeration code to make it more internally
     consistent and robust and drop the force_remove sysfs attribute
     that could be used to tell it to ignore errors on device
     hot-removal which was dangerous in general and no real and still
     relevant use cases for it could be found (Rafael Wysocki, Michal
     Hocko).

   - Make the core device enumeration code use _PXM to associate
     platform devices created by it with specific NUMA nodes (Shanker
     Donthineni).

   - Extend the CPPC library by adding more sysfs entries for
     performance capabilities to it and making it use the lowest
     nonlinear performance parameter (Prashanth Prakash).

   - Make the CPU online more consistent with CPU initialization in the
     ACPI processor driver (Prashanth Prakash).

   - Update the AC and battery drivers to help them avoid attaching to
     devices that cannot be handled by them and update the
     axp288_charger power supply driver to work correctly on ACPI
     systems without the INT3496 device (Hans de Goede).

   - Add an ACPI operation region driver for the Intel CHT Whiskey Cove
     PMIC and update the xpower operation region driver to work without
     IIO which isn't really necessary for it to work (Hans de Goede).

   - Add a new entry for Dell Inspiron 7537 to the _REV quirk blacklist
     (Kai Heng Feng).

   - Make the code in the ACPI video driver easier to follow by adding
     symbols and comments to it (Dmitry Frank).

   - Update ACPI documentation and drop a function that has no users
     from the tables-handling code (Cao jin, Baoquan He)"

Description:
Since the force_remove is inherently broken and dangerous to
use for some hotplugable resources like memory (because ignoring
the offline failure might lead to memory corruption and crashes)
enabling this knob is not safe and thus unsupported.
