9f9cd7ee2c ACPI / Thermal / video: fix max_level incorrect value
commit 059500940d (ACPI/video: export acpi_video_get_levels)
mistakenly dropped the correct value of max_level and that caused the
set_level function following failed and the acpi_video backlight interface
didn't get created. Fix this by passing back the correct max_level value.

While at it, also fix the param used in acpi_video_device_lcd_query_levels
where acpi_handle is expected but acpi_video_device is passed.

1f40c49570 libnvdimm for 4.7
1/ Device DAX for persistent memory:
    Device DAX is the device-centric analogue of Filesystem DAX
    (CONFIG_FS_DAX).  It allows memory ranges to be allocated and mapped
    without need of an intervening file system.  Device DAX is strict,
    precise and predictable.  Specifically this interface:
 
    a) Guarantees fault granularity with respect to a given page size
       (pte, pmd, or pud) set at configuration time.
 
    b) Enforces deterministic behavior by being strict about what fault
       scenarios are supported.
 
    Persistent memory is the first target, but the mechanism is also
    targeted for exclusive allocations of performance/feature differentiated
    memory ranges.
 
 2/ Support for the HPE DSM (device specific method) command formats.
    This enables management of these first generation devices until a
    unified DSM specification materializes.
 
 3/ Further ACPI 6.1 compliance with support for the common dimm
    identifier format.
 
 4/ Various fixes and cleanups across the subsystem.

Pull libnvdimm updates from Dan Williams:
 "The bulk of this update was stabilized before the merge window and
  appeared in -next.  The "device dax" implementation was revised this
  week in response to review feedback, and to address failures detected
  by the recently expanded ndctl unit test suite.

  Not included in this pull request are two dax topic branches (dax
  error handling, and dax radix-tree locking).  These topics were
  deferred to get a few more days of -next integration testing, and to
  coordinate a branch baseline with Ted and the ext4 tree.  Vishal and
  Ross will send the error handling and locking topics respectively in
  the next few days.

  This branch has received a positive build result from the kbuild robot
  across 226 configs.

  Summary:

   - Device DAX for persistent memory: Device DAX is the device-centric
     analogue of Filesystem DAX (CONFIG_FS_DAX).  It allows memory

     Specifically this interface:

         (pte, pmd, or pud) set at configuration time.

      b) Enforces deterministic behavior by being strict about what
         fault scenarios are supported.

     Persistent memory is the first target, but the mechanism is also

e4f35c1339 ACPI / video: mark acpi_video_get_levels() inline
A recent patch added a stub function for acpi_video_get_levels when
CONFIG_ACPI_VIDEO is disabled. However, this is marked as 'static'
and causes a warning about an unused function whereever the header
gets included:

In file included from ../drivers/gpu/drm/radeon/radeon_acpi.c:28:0:
include/acpi/video.h:74:12: error: 'acpi_video_get_levels' defined but not used [-Werror=unused-function]

This makes the declaration 'static inline', which gets rid of the
warning.

ACPICA commit b2294cae776f5a66a7697414b21949d307e6856f

This patch removes unwanted spaces for typedef. This solution doesn't cover
function types.

Note that the linuxize result of this commit is very giant and should have
many conflicts against the current Linux upstream. Thus it is required to
modify the linuxize result of this commit and the commits around it
manually in order to have them merged to the Linux upstream. Since this is
very costy, we should do this only once, and if we can't ensure to do this
only once, we need to revert the Linux code to the wrong indentation result
before merging the linuxize result of this commit. Lv Zheng.

c7e16e5257 acpi: widen acpi_evaluate_dsm() revision and function-index arguments
The ACPI specification states that arguments "Revision ID" and "Function
Index" to a _DSM are type "Integer."  Type Integers are 64 bit
quantities.

The function evaluate_dsm specifies these types as simple "int" which
are 32 bits.  Widen type passed to acpi_evaluate_dsm and its callers and
derived callers to pass correct type.

acpi_check_dsm and acpi_evaluate_dsm_typed had similar issue and were
corrected as well.

This is in preparation for libnvdimm implementing a generic _DSM
passthrough facility to have the capacity to pass 64-bit values as the
ACPI specification allows.

c68ae33e7f ACPI / utils: Rename acpi_dev_present()
acpi_dev_present() was originally named after pci_dev_present()
to signify the similarity of the two functions.

However Rafael J. Wysocki pointed out that the exported function
acpi_dev_present() is easily confused with the non-exported
acpi_device_is_present(). Additionally in ACPI parlance the term
"present" usually refers to the "device is present" bit returned
by the _STA control method, yet acpi_dev_present() merely checks
presence in the namespace. It does not invoke _STA at all, let
alone check the "device is present" bit.

As suggested by Rafael, rename the function to acpi_dev_found()
and adjust all existing call sites.

4ac78baf88 ACPICA: IORT: Add in support for the SMMUv3 subtable
ACPICA commit 9f7c3e148f440049615e2791d73b292f65692d7e

The most recent version of the IORT specification adds in a definition
for a subtable to describe SMMUv3 devices; there is already a subtable
for SMMUv1/v2 devices.

Add in the definition of the subtable, add in the code to compile it,
and add in a template for it.

504997cf96 ACPI / sleep: move acpi_processor_sleep to sleep.c
acpi_processor_sleep is neither related nor used by CPUIdle framework.
It's used in system suspend/resume path as a syscore operation. It makes
more sense to move it to acpi/sleep.c where all the S-state transition
(a.k.a. Linux system suspend/hiberate) related code are present.

Also make it depend on CONFIG_ACPI_SYSTEM_POWER_STATES_SUPPORT so that
it's not compiled on architecture like ARM64 where S-states are not
yet defined in ACPI.

db62fda318 ACPI / processor : add support for ACPI0010 processor container
ACPI 6.0 adds support for optional processor container device which may
contain child objects that are either processor devices or other processor
containers. This allows representing hierarchical processor topologies.

It is declared using the _HID of ACPI0010. It is an abstract container
used to represent CPU topology and should not be used to hotplug
purposes.

If no matching handler is found for a device in acpi_scan_attach_handler,
acpi_bus_attach does a default enumeration for those devices with valid
HID in the acpi namespace. This patch adds a scan handler for these ACPI
processor containers to avoid default that enumeration and ensures the
platform devices are not created for them.

e3e9b577b4 ACPICA: Drop Linux-specific waking vector functions
Commit f06147f9fb (ACPICA: Hardware: Enable firmware waking vector
for both 32-bit and 64-bit FACS) added three functions that aren't
present in upstream ACPICA, acpi_hw_set_firmware_waking_vectors(),
acpi_set_firmware_waking_vectors() and acpi_set_firmware_waking_vector64(),
to allow Linux to use the previously existing API for setting the
platform firmware waking vector.

However, that wasn't necessary, since the ACPI sleep support code
in Linux can be modified to use the upstream ACPICA's API easily
and the additional functions may be dropped which reduces the code
size and puts the kernel's ACPICA code more in line with the upstream.

Make the changes as per the above.  While at it, make the relevant
function desctiption comments reflect the upstream ACPICA's ones.

ACPICA commit 071eff738c59eda1792ac24b3b688b61691d7e7c

Execute any module-level code after each ACPI table (DSDT or SSDT)
is loaded into the namespace (rather than after all AML tables have
been loaded).  This matches the behavior of other ACPI
implementations and is required to support BIOS code that
depends on this behavior.
