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.

ACPICA commit 60d9cfd403a9824199b971597c930f6f563e5c71

Allows all object types to be used with Concatenate. Objects
other than Int/Str/Buf are convert to a string that contains
the type of the object. Improves the utility of the Printf
and Fprintf macros.

Adds a new file, exconcat.c

Subject: ACPICA: Utilities: Update for strtoul64 merger

ACPICA commit 795e136d2ac77c1c8b091fba019b5fe36a44a323

Fixes a problem with the merger of the two internal versions
of this function. Make the maximum integer width (32-bit or
64-bit) a parameter to the function so that it no longer
exclusively uses the integer width specified in the DSDT/SSDT.

+ *              acpi_gbl_integer_byte_width should be set to the proper width.

From 7447bc1e69bafab72ef69a7f054bb1e5f9ff908d Mon Sep 17 00:00:00 2001
From: Bob Moore <robert.moore@intel.com>
Date: Thu, 24 Mar 2016 09:40:48 +0800
Subject: ACPICA: iASL/Disassembler: Improve handling of unresolved methods

ACPICA commit 16cd0872a070c8d3b16b8b13c1fc90a443a6b6fe

If the definition of a control method cannot be found (probably it
is in another module/SSDT), the disassembler must try to guess
at the number of arguments to that method. This change improves
the guessing heuristic.

Subject: ACPICA: Utilities: Add ACPI_IS_POWER_OF_TWO()

ACPICA commit cbcb77565c5032dd48e19b3a8a8b8704c5f29faf

This patch adds a macro ACPI_IS_POWER_OF_TWO, which can be used to
detect if a number is a power of two. Lv Zheng.

Some compilers require parentheses to be enforced in the macro definition,
so that the macro caller side can be simpler.

This patch fixes this kind of macro issue in
ACPI_SET_BITS()/ACPI_GET_BITS(). Lv Zheng.

Subject: ACPICA: Events: Fix an issue that _REG association can happen before
 namespace is initialized

ACPICA commit c508f8592efaa0d8197f26d7fee6382c5ac8e383

Current code flow cannot ensure _REG association can happen after the
namespace is initialized, so we move _REG association to where _REG was
about to run to fix this issue.

This issue is detected when acpi_ev_initialize_region() is invoked during
the table loading. And this is one of the most important the root cause why
ACPICA table loading is split into 2 load passes. Lv Zheng.

Subject: ACPICA: Namespace: Reorder \_SB._INI to make sure it is evaluated
 before _REG evaluations

ACPICA commit f005ee6b90d152c1f499efcca6b771a93903cb55

This patch splits \_SB._INI evaluation from device initialization code, so
that it can be performed before PCI_Config _REG evaluations. This is
required for the device enumeration process. Some named objects are
initialized in \_SB._INI and PCI_Config _REG evaluations may use
uninitialized named objects because of the order issue.

This must be fixed before fixing ECDT order issue. There are existing
tables allowing ECDT EC to be used for the entire device enumeration
process, but the enabling of ECDT EC is done in \_SB._INI. Thus \_SB._INI
must be the first control method evaluated in the device enumeration
process. Normally, the order should be automatically ensured by the device
enumeration process itself (for example, PCI_Config _REGs are evaluated by
the PCI bus driver when the driver is probed by the enumeration process),
but since the process is split on Linux (partially done in Linux, partially
done in ACPICA), we need to ensure this with special logics in order to be
regression safe. Lv Zheng.

Subject: acpi/nfit: Update nfit driver to comply with ACPI 6.1

ACPI 6.1, Table 5-133, updates NVDIMM Control Region Structure
as follows.
 - Valid Fields, Manufacturing Location, and Manufacturing Date
   are added from reserved range.  No change in the structure size.
 - IDs (SPD values) are stored as arrays of bytes (i.e. big-endian
   format).  The spec clarifies that they need to be represented
   as arrays of bytes as well.

This patch makes the following changes to support this update.
 - Change the NFIT driver to show SPD ID values in big-endian
   format.
 - Change sprintf format to use "0x" instead of "#" since "%#02x"
   does not prepend '0'.

Subject: acpi/nfit: Add sysfs "id" for NVDIMM ID

ACPI 6.1, section 5.2.25.9, defines an identifier for an NVDIMM.

Change the NFIT driver to add a new sysfs file "id" under nfit
directory.

Similar to pci-sysfs export the subsystem information available in the
NFIT.  ACPI 6.1 clarifies that this data is copied as an array of bytes
