This patch copies EFI interface definitions to the ACPICA code base so that
the EFI utility support can be ported to other EFI implementation.

Known issues:
1. MS Builds of uefi_call_wrapper()
   The uefi_call_wrapper() in GNU EFI is implemented in a the way to work
   around the ABI difference between Unix and MS. While I don't have
   environment to test the MS builds.

In order to port the ACPICA utilities to other EFI implementation, all that
need to be done is to impelement the 64-bit division support and the
program entry point where the efi_main() is invoked. Code to impelement
these is platform specific, and ACPICA currently choose to hide such
platform specific code within the specific EFI impelementation. Lv Zheng.

the FACS table reported via FADT's X_FIRMWARE_CTRL field.

The root cause of the reported bug might be one of the followings:
1. BIOS may favor the 64-bit firmware waking vector address when the
   version of the FACS is greater than 0 and Linux currently only supports
   resuming from the real mode, so the 64-bit firmware waking vector has
   never been set and might be invalid to BIOS while the commit enables
   higher version FACS.
2. BIOS may favor the FACS reported via the "FIRMWARE_CTRL" field in the
   FADT while the commit doesn't set the firmware waking vector address of

   vector address of the FACS reported by "X_FIRMWARE_CTRL".

This patch excludes the cases that can trigger the bugs caused by the root
cause 2.

There is no handshaking mechanism can be used by OSPM to tell BIOS which
FACS is currently used. Thus the FACS reported by "FIRMWARE_CTRL" may still
be used by BIOS and the 0 value of the 32-bit firmware waking vector might
trigger such failure.

This patch enables the firmware waking vectors for both 32bit/64bit FACS

 Commit: 0249ed2444d65d65fc3f3f64f398f1ad0b7e54cd

   vector address of the FACS reported by "X_FIRMWARE_CTRL".

This patch excludes the cases that can trigger the bugs caused by the root
cause 1.

ACPI specification says:
A. 32-bit FACS address (FIRMWARE_CTRL field in FADT):
   Physical memory address of the FACS, where OSPM and firmware exchange
   control information.
   If the X_FIRMWARE_CTRL field contains a non zero value then this field
   must be zero.
   A zero value indicates that no FACS is specified by this field.
B. 64-bit FACS address (X_FIRMWARE_CTRL field in FADT):
   64bit physical memory address of the FACS.
   This field is used when the physical address of the FACS is above 4GB.
   If the FIRMWARE_CTRL field contains a non zero value then this field
   must be zero.
   A zero value indicates that no FACS is specified by this field.
Thus the 32bit and 64bit firmware waking vector should indicate completely
different resuming environment - real mode (1MB addressable) and non real
mode (4GB+ addressable) and currently Linux only supports resuming from
real mode.

This patch enables 64-bit firmware waking vector for selected FACS via new
acpi_set_firmware_waking_vectors() API so that it's up to OSPMs to
determine which resuming mode should be used by BIOS and ACPICA changes
won't trigger the bugs caused by the root cause 1. Lv Zheng.

ACPICA: ACPI 6.0: Add support for IORT table.

ACPICA commit 5de82757aef5d6163e37064033aacbce193abbca

This patch adds support for IORT (IO Remapping Table) in iasl.

Note that some field names are modified to shrink their length or the
decompiled IORT ASL will contain fields with ugly ":" alignment.

The IORT contains field definitions around "Memory Access Properties". This
patch also adds support to encode/decode it using inline table.

This patch doesn't add inline table support for the SMMU interrupt fields
due to a limitation in current ACPICA data table support. Lv Zheng.

acpi_hw_build_pci_list() so that the caller of acpi_hw_build_pci_list() needn't

drm: Zero out invalid vblank timestamp in drm_update_vblank_count.

Since commit 844b03f27739135fe1fed2fef06da0ffc4c7a081 we make
sure that after vblank irq off, we return the last valid
(vblank count, vblank timestamp) pair to clients, e.g., during
modesets, which is good.

An overlooked side effect of that commit for kms drivers without
support for precise vblank timestamping is that at vblank irq
enable, when we update the vblank counter from the hw counter, we
can't update the corresponding vblank timestamp, so now we have a
totally mismatched timestamp for the new count to confuse clients.

Restore old client visible behaviour from before Linux 3.17, but
zero out the timestamp at vblank counter update (instead of disable
as in original implementation) if we can't generate a meaningful
timestamp immediately for the new vblank counter. This will fix
this regression, so callers know they need to retry again later
if they need a valid timestamp, but at the same time preserves
the improvements made in the commit mentioned above.

  a rewrite of the PXA lubbock/mainstone IRQ handling.  This was already
  broken in 2011 by a change to the GPIO code and only noticed now.

  The other changes contained here are:

  MAINTAINERS file updates:

   - Ray Jui and Scott Branden are now co-maintainers for some of the
     mach-bcm chips, while Christian Daudt and Marc Carino have stepped
     down.

   - Andrew Victor is no longer maintaining at91.  Instead, Alexandre
     Belloni now becomes an official maintainer, after having done a
     bulk of the work for a while.

   - Baruch Siach, who added the mach-digicolor platform in 4.1 is now
     listed as maintainer

   - The git URL for mach-socfpga has changed

  Bug fixes:

   - Three bug fixes for new rockchip rk3288 code

   - A regression fix to make SD card support work on certain ux500
     boards

   - multiple smaller dts fixes for imx, omap, mvebu, and shmobile

   - a regression fiix for omap3 power consumption

   - a fix for regression in the ARM CCI bus driver

drm/amdkfd: Initialize sdma vm when creating sdma queue

This patch fixes a bug where sdma vm wasn't initialized when
an sdma queue was created in HWS mode.

This caused GPUVM faults to appear on dmesg and it is one of the
causes that SDMA queues are not working.

drm/i915: Drop PIPE-A quirk for 945GSE HP Mini

Since the introduction of BIOS fb preservation, circa 3.17, we began
encountering a failure during boot when trying to use force-detect
before GEM was initialised. That bug is from

commit 7fad798e16fecddd41c6a91728a09f0b9507e40c
Author: Daniel Vetter <daniel.vetter@ffwll.ch>

    drm/i915: ensure the force pipe A quirk is actually followed

but investigation of the affected machine revealed that it was using a
PIPE-A quirk even though it was a 945GSE and the quirk is only supposed
to be used to workaround a hardware issue on 830/845. That quirk was
added for this HP Mini in

commit 6b93afc564a5e74b0eaaa46c95f557449951b3b9
Author: Bryce Harrington <bryce@bryceharrington.org>
Date:   Wed May 27 03:40:52 2009 -0700

    add pipe a force quirk for Dell mini

in order to workaround an issue with the BIOS behaving strangely during
lid-close. Since then we have a much larger hammer to thwart the BIOS
after opening the lid and the PIPE-A quirk is no longer required.
