8d3523fb3b ACPI / osl: Remove deprecated acpi_get_table_with_size()/early_acpi_os_unmap_memory() 
Since all users are cleaned up, remove the 2 deprecated APIs due to no
users.
As a Linux variable rather than an ACPICA variable, acpi_gbl_permanent_mmap
is renamed to acpi_permanent_mmap to have a consistent coding style across
entire Linux ACPI subsystem.

6b11d1d677 ACPI / osl: Remove acpi_get_table_with_size()/early_acpi_os_unmap_memory() users 
This patch removes the users of the deprectated APIs:
 acpi_get_table_with_size()
 early_acpi_os_unmap_memory()
The following APIs should be used instead of:
 acpi_get_table()
 acpi_put_table()

The deprecated APIs are invented to be a replacement of acpi_get_table()
during the early stage so that the early mapped pointer will not be stored
in ACPICA core and thus the late stage acpi_get_table() won't return a
wrong pointer. The mapping size is returned just because it is required by
early_acpi_os_unmap_memory() to unmap the pointer during early stage.

But as the mapping size equals to the acpi_table_header.length
(see acpi_tb_init_table_descriptor() and acpi_tb_validate_table()), when
such a convenient result is returned, driver code will start to use it
instead of accessing acpi_table_header to obtain the length.

Thus this patch cleans up the drivers by replacing returned table size with
acpi_table_header.length, and should be a no-op.

66360faa43 ACPICA: Tables: Allow FADT to be customized with virtual address 
ACPICA commit d98de9ca14891130efc5dcdc871b97eb27b4b0f5

FADT parsing code requires FADT to be installed as
ACPI_TABLE_ORIGIN_INTERNAL_PHYSICAL, using new
acpi_tb_get_table()/acpi_tb_put_table(), other address types can also be allowed,
thus facilitates FADT customization with virtual address. Lv Zheng.

174cc7187e ACPICA: Tables: Back port acpi_get_table_with_size() and early_acpi_os_unmap_memory() from Linux kernel 
ACPICA commit cac6790954d4d752a083e6122220b8a22febcd07

This patch back ports Linux acpi_get_table_with_size() and
early_acpi_os_unmap_memory() into ACPICA upstream to reduce divergences.

The 2 APIs are used by Linux as table management APIs for long time, it
contains a hidden logic that during the early stage, the mapped tables
should be unmapped before the early stage ends.

During the early stage, tables are handled by the following sequence:
 acpi_get_table_with_size();
 parse the table
 early_acpi_os_unmap_memory();
During the late stage, tables are handled by the following sequence:
 acpi_get_table();
 parse the table
Linux uses acpi_gbl_permanent_mmap to distinguish the early stage and the
late stage.

The reasoning of introducing acpi_get_table_with_size() is: ACPICA will
remember the early mapped pointer in acpi_get_table() and Linux isn't able to
prevent ACPICA from using the wrong early mapped pointer during the late
stage as there is no API provided from ACPICA to be an inverse of
acpi_get_table() to forget the early mapped pointer.

But how ACPICA can work with the early/late stage requirement? Inside of
ACPICA, tables are ensured to be remained in "INSTALLED" state during the
early stage, and they are carefully not transitioned to "VALIDATED" state
until the late stage. So the same logic is in fact implemented inside of
ACPICA in a different way. The gap is only that the feature is not provided
to the OSPMs in an accessible external API style.

It then is possible to fix the gap by providing an inverse of
acpi_get_table() from ACPICA, so that the two Linux sequences can be
combined:
 acpi_get_table();
 parse the table
 acpi_put_table();
In order to work easier with the current Linux code, acpi_get_table() and
acpi_put_table() is implemented in a usage counting based style:
 1. When the usage count of the table is increased from 0 to 1, table is
    mapped and .Pointer is set with the mapping address (VALIDATED);
 2. When the usage count of the table is decreased from 1 to 0, .Pointer
    is unset and the mapping address is unmapped (INVALIDATED).
So that we can deploy the new APIs to Linux with minimal effort by just
invoking acpi_get_table() in acpi_get_table_with_size() and invoking
acpi_put_table() in early_acpi_os_unmap_memory(). Lv Zheng.

ce38207f16 sound updates for 4.10-rc1 
No dramatic changes are found in this development cycle, but as usual,
 many commits are applied in a wide range of drivers.
 
 Most of big changes are in ASoC, where a few bits of framework work
 and quite a lot of cleanups and improvements to existing code have
 been done.  The rest are usual stuff, a few HD-audio and USB-audio
 quirks and fixes, as well as the drop of kthread usages in the whole
 subsystem.
 
 Below are some highlights:
 
 ASoC:
 - Support for stereo DAPM controls
 - Some initial work on the of-graph sound card
 - regmap conversions of the remaining AC'97 drivers
 - A new version of the topology ABI; this should be backward compatible
 - Updates / cleanups of rsnd, sunxi, sti, nau8825, samsung, arizona,
   Intel skylake, atom-sst
 - New drivers for Cirrus Logic CS42L42, Qualcomm MSM8916-WCD, and
   Realtek RT5665
 
 USB-audio:
 - Yet another race fix at disconnection
 - Tolerated packet size calculation for some Android devices
 - Quirks for Axe-Fx II, QuickCam, TEAC 501/503
 
 HD-audio:
 - Improvement of Dell pin fixup mapping
 - Quirks for HP Z1 Gen3, Alienware 15 R2 2016 and ALC622 headset mic
 
 Misc:
 - Replace all kthread usages with simple works

2a4c32edd3 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/shli/md 
Pull MD updates from Shaohua Li:

 - a raid5 writeback cache feature.

   The goal is to aggregate writes to make full stripe write and reduce
   read-modify-write. It's helpful for workload which does sequential
   write and follows fsync for example. This feature is experimental and
   off by default right now.

 - FAILFAST support.

   This fails IOs to broken raid disks quickly, so can improve latency.
   It's mainly for DASD storage, but some patches help normal raid array
   too.

 - support bad block for raid array with external metadata

 - AVX2 instruction support for raid6 parity calculation

 - normalize MD info output

 - add missing blktrace

 - other bug fixes

a829a8445f SCSI misc on 20161213 
This update includes the usual round of major driver updates (ncr5380,
 lpfc, hisi_sas, megaraid_sas, ufs, ibmvscsis, mpt3sas).  There's also
 an assortment of minor fixes, mostly in error legs or other not very
 user visible stuff.  The major change is the pci_alloc_irq_vectors
 replacement for the old pci_msix_.. calls; this effectively makes IRQ
 mapping generic for the drivers and allows blk_mq to use the
 information.

846221cfb8 Remove references to dead make variable LINUX_INCLUDE 
Commit 4fd06960f1 ("Use the new x86 setup code for i386") introduced a
reference to the make variable LINUX_INCLUDE. That reference got moved
around a bit and copied twice and now there are three references to it.

There has never been a definition of that variable. (Presumably that is
because it started out as a mistyped reference to LINUXINCLUDE.) So this
reference has always been an empty string. Let's remove it before it
spreads any further.

The build system stopped generating ikconfig.h in v2.6.8. Remove an entry
for it in dontdiff. There's also a reference to it in a small comment.
Remove that comment too, as it is of little help in any case.

95f21c5c6d Documentation/device-mapper: s/getsize/getsz/ 
According to `man blockdev':

  --getsize
         Print device size (32-bit!) in sectors.
         Deprecated in favor of the --getsz option.
  ...
  --getsz
         Get size in 512-byte sectors.

Hence, occurrences of `--getsize' should be replaced with `--getsz',
which this commit has achieved as follows:

  $ cd "$repo"
  $ git grep -l -e --getsz

cdb98c2698 Revert "nvme: add support for the Write Zeroes command" 
This reverts commit 6d31e3ba23.

This causes bootup problems for me both on my laptop and my desktop.
What they have in common is that they have NVMe disks with dm-crypt, but
it's not the same controller, so it's not controller-specific.

Jens does not see it on his machine (also NVMe), so it's presumably
something that triggers just on bootup.  Possibly related to dm-crypt
and the fact that I mark my luks volume with "allow-discards" in
/etc/crypttab.

It's 100% repeatable for me, which made it fairly straightforward to
bisect the problem to this commit. Small mercies.

So we don't know what the reason is yet, but the revert is needed to get
things going again.

bb3dd056ed spi: Updates for v4.10 
The nicest things about this release for me is seeing some older drivers
 getting some cleanups and modernization, it's really good to see things
 moving forwards even for older drivers.  In content terms it's a fairly
 humdrum release but where the work has been happening is great.
 
  - Support for simultaneous use of internal and GPIO chip selects for
    devices that require the use of the internal select even if it's not
    connected and a GPIO is actually routed to the slave device.
  - A major rework and cleanup of the fsl-espi driver from Heiner
    Kallweit which should make it work substantially better.
  - DMA support for Freescale DSPI IPs.
  - New drivers for Freescale LPSPI IPs and Marvell Armada 3700.
  - Support for Allwinner H3.

Pull spi updates from Mark Brown:
 "The nicest things about this release for me is seeing some older
  drivers getting some cleanups and modernization, it's really good to
  see things moving forwards even for older drivers.

  In content terms it's a fairly humdrum release but where the work has
  been happening is great.

   - Support for simultaneous use of internal and GPIO chip selects for
     devices that require the use of the internal select even if it's
     not connected and a GPIO is actually routed to the slave device.

   - A major rework and cleanup of the fsl-espi driver from Heiner
     Kallweit which should make it work substantially better.

   - DMA support for Freescale DSPI IPs.

   - New drivers for Freescale LPSPI IPs and Marvell Armada 3700.

   - Support for Allwinner H3"

  It makes libata skip probing for NCQ prio unless the feature is

9f56eca3ae ata: avoid probing NCQ Prio Support if not explicitly requested 
Previously, when the ata device was being initialized we were
probing for NCQ prio support by checking the identify information
and also checking the log page that holds information about ncq prio
support.

This caused an error on an Intel HBA so the code is now updated to
only probe for NCQ prio support when the sysfs variable controlling
NCQ prio support is enabled.

tj: Update formatting, switch to spin_[un]lock_irq() and update
    locking a bit, use REVALIDATE instead of RESET, and return -EIO
    instead of -EINVAL on config failure.

Pull libata updates from Tejun Heo:

 - Adam added opt-in ATA command priority support.

 - There are machines which hide multiple nvme devices behind an ahci
   BAR. Dan Williams proposed a solution to force-switch the mode but
   deemed too hackishd. People are gonna discuss the proper way to
   handle the situation in nvme standard meetings. For now, detect and
   warn about the situation.

 - Low level driver specific changes.

Christoph Hellwig pipes in about the hidden nvme warning:
 "I wish that was the case. We've pretty much agreed that we'll want to
  implement it as a virtual PCIe root bridge, similar to Intels other
  'innovation' VMD that we work around that way.

  But Intel management has apparently decided that they don't want to
  spend more cycles on this now that Lenovo has an optional BIOS that
  doesn't force this broken mode anymore, and no one outside of Intel
  has enough information to implement something like this.

  So for now I guess this warning is it, until Intel reconsideres and
  spends resources on fixing up the damage their Chipset people caused"

 Big thing here is the nice addition of "functional dependencies" to the
 driver core.  The idea has been talked about for a very long time, great
 job to Rafael for stepping up and implementing it. It's been tested for
 longer than the 4.9-rc1 date, we held off on merging it earlier in order
 to feel more comfortable about it.
 
 Other than that, it's just a handful of small other patches, some good
 cleanups to the mess that is the firmware class code, and we have a test
 driver for the deferred probe logic.

 removed (got a "clean" driver for the same hardware through the netdev
 tree), and some iio drivers were also dropped, but I think we ended up
 adding a few thousand lines to the source tree in the end.  Other than
 that it's a lot of minor fixes all over the place, nothing major stands
 out at all.
 
 All of these have been in linux-next for a while.  There will be a merge
 conflict with Al's vfs tree in the lustre code, but the resolution for
 that should be pretty simple, that too has been in linux-next.

  the rest waiting for an issue discovered in linux-next to be
  addressed) which brings in a couple of fixes and cleanups

  On top of that initial support for APEI on ARM64 is added, two new
  pieces of documentation are introduced, the properties-parsing code is
  updated to follow changes in the (external) documentation it is based
  on and there are a few updates of SoC drivers, some new blacklist
  entries, plus some assorted fixes and cleanups

  Specifics:

   - ACPICA update including upstream revision 20160930 and several
     commits beyond it (Bob Moore, Lv Zheng)

   - Initial support for ACPI APEI on ARM64 (Tomasz Nowicki)

   - New document describing the handling of _OSI and _REV in Linux (Len
     Brown)

   - New document describing the usage rules for _DSD properties (Rafael
     Wysocki)

   - Update of the ACPI properties-parsing code to reflect recent
     changes in the (external) documentation it is based on (Rafael
     Wysocki)

   - Updates of the ACPI LPSS and ACPI APD SoC drivers for additional
     hardware support (Andy Shevchenko, Nehal Shah)

   - New blacklist entries for _REV and video handling (Alex Hung, Hans
     de Goede, Michael Pobega)

   - ACPI battery driver fix to fall back to _BIF if _BIX fails (Dave
     Lambley)

   - NMI notifications handling fix for APEI (Prarit Bhargava)

   - Error code path fix for the ACPI CPPC library (Dan Carpenter)

Pull power management updates from Rafael Wysocki:
 "Again, cpufreq gets more changes than the other parts this time (one
  new driver, one old driver less, a bunch of enhancements of the
  existing code, new CPU IDs, fixes, cleanups)

  There also are some changes in cpuidle (idle injection rework, a
  couple of new CPU IDs, online/offline rework in intel_idle, fixes and
  cleanups), in the generic power domains framework (mostly related to
  supporting power domains containing CPUs), and in the Operating
  Performance Points (OPP) library (mostly related to supporting devices
  with multiple voltage regulators)

  In addition to that, the system sleep state selection interface is
  modified to make it easier for distributions with unchanged user space
  to support suspend-to-idle as the default system suspend method, some
  issues are fixed in the PM core, the latency tolerance PM QoS
  framework is improved a bit, the Intel RAPL power capping driver is
  cleaned up and there are some fixes and cleanups in the devfreq
