2e7cc46a0f ACPICA: iASL: Enhancement for constant folding.
ACPICA commit 4f9e950d41cd6f6c704d5d6cf518647620d65e99

Add support to fold expressions with a target operand -- these are
folded and converted to a Store operator:

Add (4, 3, INT1) --> Store (7, INT1)

Also supports ASL+ constructs:

INT1 = 4 + 3 --> Store (7, INT1)

8b0b1a9976 ACPICA: iASL/Disassembler: Add option to assume table contains valid AML.
ACPICA commit f5d2ff3fa05341d9fe27250fcb2e14c7f871432c

For dynamically loaded tables that have unknown ACPI signatures,
this option (-df) forces the disassembler to treat the table as if
it contains valid AML code (like a DSDT or SSDT). Otherwise, the
disassembler will treat the table as an unkown data table and
simply do a hex dump of the table.

Linux kernel is not affected by this patch.

76cffa79bd ACPICA: Tables: Move an iasl specific table function to iasl source file.
ACPICA commit 6eb364d790dd103bd4990f808e0095a421c437cb

acpi_tb_store_table() implements a logic that is only correct to iasl. So it
won't be used by any other utilities except iasl. This function is
complained by the kernel users as an unused function. The best choice to
stop releasing it to the Linux kernel should be moving it to adisasm.c.

ACPI table manager can use both struct acpi_table_desc (direct referencing)
and table index (indirect referencing) as the descriptor to the table, so
acpi_tb_get_next_root_index() is extended to return both of them to allow
maximum usability from the callers. NOTE that indirect referencing is a
design result to meet the boot stage static allocation requirement for the
table descriptors.

This is a linuxized acpi_tb_store_table() removing result, there should be
no functional changes introduced to the Linux kernel by this patch except
the additonal kernel unused argument for acpi_tb_get_next_root_index()
(renamed to acpi_tb_get_next_root_index()). This argument is used in the
ACPICA upstream.

09af8e8290 ACPICA: Events: Add support to return both enable/status register values for GPE and fixed event.
ACPICA commit e25d791e4b3d5b9f4ead298269610cb05f89749a

There is a facility in Linux, developers can obtain GPE and fixed event
status via /sys/firmware/interrupts/. This is implemented using
acpi_get_event_status() and acpi_get_gpe_status(). Recently while debugging some
GPE race issues, it is found that the facility is lacking in the ability to
obtain real hardware register values, the confusing information makes
debugging difficult.

This patch modifies acpi_get_gpe_status() to return EN register values to fix
this gap. Then flags returned from acpi_get_event_status() and
acpi_get_gpe_status() are also cleaned up to reflect this change.

The old ACPI_EVENT_FLAG_SET is carefully kept to avoid regressions. It can
be deleted after we can make sure all its references are removed from OSPM
code. Lv Zheng.

2b8760100e ACPICA: Utilities: split IO address types from data type models.
ACPICA commit aacf863cfffd46338e268b7415f7435cae93b451

It is reported that on a physically 64-bit addressed machine, 32-bit kernel
can trigger crashes in accessing the memory regions that are beyond the
32-bit boundary. The region field's start address should still be 32-bit
compliant, but after a calculation (adding some offsets), it may exceed the
32-bit boundary. This case is rare and buggy, but there are real BIOSes
leaked with such issues (see References below).

This patch fixes this gap by always defining IO addresses as 64-bit, and
allows OSPMs to optimize it for a real 32-bit machine to reduce the size of
the internal objects.

Internal acpi_physical_address usages in the structures that can be fixed
by this change include:
 1. struct acpi_object_region:
    acpi_physical_address		address;
 2. struct acpi_address_range:
    acpi_physical_address		start_address;
    acpi_physical_address		end_address;
 3. struct acpi_mem_space_context;
    acpi_physical_address		address;
 4. struct acpi_table_desc
    acpi_physical_address		address;
See known issues 1 for other usages.

Note that acpi_io_address which is used for ACPI_PROCESSOR may also suffer
from same problem, so this patch changes it accordingly.

For iasl, it will enforce acpi_physical_address as 32-bit to generate
32-bit OSPM compatible tables on 32-bit platforms, we need to define
ACPI_32BIT_PHYSICAL_ADDRESS for it in acenv.h.

Known issues:
 1. Cleanup of mapped virtual address
   In struct acpi_mem_space_context, acpi_physical_address is used as a virtual
   address:
    acpi_physical_address                   mapped_physical_address;
   It is better to introduce acpi_virtual_address or use acpi_size instead.
   This patch doesn't make such a change. Because this should be done along
   with a change to acpi_os_map_memory()/acpi_os_unmap_memory().
   There should be no functional problem to leave this unchanged except
   that only this structure is enlarged unexpectedly.

ACPICA commit b60612373a4ef63b64a57c124576d7ddb6d8efb6

4c27283415 drm/i915: add bxt gmbus support
For BXT gmbus is pulled from PCH to CPU. From implementation point of
view only pin pair configuration will change. The existing
implementation supports all platforms previous to GEN8 and also SKL. But
for BXT pin pair configuration is completely different than SKL or other
previous GEN's. This patch introduces the new pin pair configuration
structure specific to BXT and also ensures every real gmbus port has a
gpio pin.

v3 by Jani: with the platform independent prep work in place, the bxt
enabling reduces to a fairly trivial patch. Credits are due Sunil for
giving me the ideas (with his patches) what the platform independent
parts should look like.

4acd09b4bf powerpc/cell: Fix iommu breakage caused by controller_ops change
The recent patch to convert cell to use pci_controller_ops had a small
bug which broke machines using an iommu.

The set of phb->controller_ops was added after the check for name !=
"pci", meaning pcix/pcie PHBs weren't getting their ops set correctly.

3968be946a drm: Make integer overflow checking cover universal cursor updates (v2)
Our legacy SetPlane updates perform integer overflow checking on a
plane's destination rectangle in drm_mode_setplane(), and atomic updates
handled as part of a drm_atomic_state transaction do the same checking
in drm_atomic_plane_check().  However legacy cursor updates that get
routed through universal plane interfaces may bypass this overflow
checking if the driver's .update_plane is serviced by the transitional
plane helpers rather than the full atomic plane helpers.

Move the check for destination rectangle integer overflow from the
drm_mode_setplane() to __setplane_internal() so that it also covers
cursor operations.

This fixes an issue first noticed with i915 commit:

        commit ff42e093e9
        Author: Daniel Vetter <daniel.vetter@ffwll.ch>
        Date:   Mon Mar 2 16:35:20 2015 +0100

            Revert "drm/i915: Switch planes from transitional helpers to full
            atomic helpers"

The above revert switched us from full atomic helpers back to the
transitional helpers, and in doing so we lost the overflow checking here
for universal cursor updates.  Even though such extreme cursor positions
are unlikely to actually happen in the wild, we still don't want there
to be a change of behavior when drivers switch from transitional helpers
to full helpers.

v2: Move check from setplane ioctl to setplane_internal rather than
    adding an additional copy of the checks to the transitional plane
    helpers.  (Daniel)

4195f40685 drm/nouveau/bios: fix fetching from acpi on certain systems
nvbios_extend() returns 1 to indicate "extended the array" and 0 to
indicate the array is already big enough.  This is used by the core
shadowing code to prevent re-fetching chunks of the image that have
already been shadowed.

The ACPI fetching code may possibly need to extend this further due
to requiring fetches to happen in 4KiB chunks.

Under certain circumstances (that happen if the total image size is
a multiple of 4KiB), the memory allocated to store the shadow will
already be big enough, causing the ACPI code's nvbios_extend() call
to return 0, which is misinterpreted as a failure.

The fix is simple, accept >= 0 as a successful condition here.  The
core will have already made sure that we're not re-fetching data we
already have.

Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=89047

v2 (Ben Skeggs):
- dropped hunk which would cause unnecessary re-fetching
- more descriptive explanation

Uncertain whether the GPC pack change is due to a newer driver version,
or a legitimate difference from GM204.  My GM204 has broken vram, so
can't currently try a newer binary driver on it to confirm.
