92985ef1db ACPICA: Clean up redudant definitions already defined elsewhere
Since mis-order issues have been solved, we can cleanup redundant
definitions that already have defaults in <acpi/platform/acenv.h>.

This patch removes redudant environments for __KERNEL__ surrounded code.

07d8391433 ACPICA: Linux headers: Add <asm/acenv.h> to remove mis-ordered inclusion of <asm/acpi.h>
There is a mis-order inclusion for <asm/acpi.h>.

As we will enforce including <linux/acpi.h> for all Linux ACPI users, we
can find the inclusion order is as follows:

<linux/acpi.h>
  <acpi/acpi.h>
   <acpi/platform/acenv.h>
    (acenv.h before including aclinux.h)
    <acpi/platform/aclinux.h>
...........................................................................
     (aclinux.h before including asm/acpi.h)
     <asm/acpi.h>                             @Redundant@
      (ACPICA specific stuff)
...........................................................................
...........................................................................
      (Linux ACPI specific stuff) ? - - - - - - - - - - - - +
     (aclinux.h after including asm/acpi.h)   @Invisible@   |
    (acenv.h after including aclinux.h)       @Invisible@   |
   other ACPICA headers                       @Invisible@   |
............................................................|..............
  <acpi/acpi_bus.h>                                         |
  <acpi/acpi_drivers.h>                                     |
  <asm/acpi.h> (Excluded)                                   |
   (Linux ACPI specific stuff) ! <- - - - - - - - - - - - - +

NOTE that, in ACPICA, <acpi/platform/acenv.h> is more like Kconfig
generated <generated/autoconf.h> for Linux, it is meant to be included
before including any ACPICA code.

In the above figure, there is a question mark for "Linux ACPI specific
stuff" in <asm/acpi.h> which should be included after including all other
ACPICA header files.  Thus they really need to be moved to the position
marked with exclaimation mark or the definitions in the blocks marked with
"@Invisible@" will be invisible to such architecture specific "Linux ACPI
specific stuff" header blocks.  This leaves 2 issues:
1. All environmental definitions in these blocks should have a copy in the
   area marked with "@Redundant@" if they are required by the "Linux ACPI
   specific stuff".
2. We cannot use any ACPICA defined types in <asm/acpi.h>.

This patch splits architecture specific ACPICA stuff from <asm/acpi.h> to
fix this issue.

d13bd5a602 ACPICA: Linux headers: Add <acpi/platform/aclinuxex.h>
From ACPICA's perspective, <acpi/actypes.h> should be included after
inclusion of <acpi/platform/acenv.h>.  But currently in Linux,
<acpi/platform/aclinux.h> included by <acpi/platform/acenv.h> has
included <acpi/actypes.h> to find ACPICA types for inline functions.

This causes the following problem:
1. Redundant code in <asm/acpi.h> and <acpi/platform/aclinux.h>:
   Linux must be careful to keep conditions for <acpi/actypes.h> inclusion
   consistent with the conditions for <acpi/platform/aclinux.h> inclusion.
   Which finally leads to the issue that we have to keep many useless macro
   definitions in <acpi/platform/aclinux.h> or <asm/acpi.h>.
   Such conditions include:
     COMPILER_DEPENDENT_UINT64
     COMPILER_DEPENDENT_INT64
     ACPI_INLINE
     ACPI_SYSTEM_XFACE
     ACPI_EXTERNAL_XFACE
     ACPI_INTERNAL_XFACE
     ACPI_INTERNAL_VAR_XFACE
     ACPI_MUTEX_TYPE
     DEBUGGER_THREADING
     ACPI_ACQUIRE_GLOBAL_LOCK
     ACPI_RELEASE_GLOBAL_LOCK
     ACPI_FLUSH_CPU_CACHE
   They have default implementations in <include/acpi/platform/acenv.h>
   while Linux need to keep a copy in <asm/acpi.h> to avoid build errors.

This patch introduces <acpi/platform/aclinuxex.h> to fix this issue by
splitting conditions and declarations (most of them are inline functions)
into 2 header files so that the wrong inclusion of <acpi/actypes.h> can be
removed from <acpi/platform/aclinux.h>.

This patch also removes old ACPI_NATIVE_INTERFACE_HEADER mechanism which is
not preferred by Linux and adds the platform/acenvex.h to be the solution
to solve this issue.

83ad152d03 ASoC: jack: Clarify GPIO descriptor lookup in struct snd_soc_jack_gpio doc
Clarify struct snd_soc_jack_gpio documentation for the idx and name fields.
Because name is passed as connection ID to gpiod_get_index() when using GPIO
descriptor defined jack pins it is not only used as a label in debugfs but
also as function name lookup in systems that support functions names for
GPIOs.

Clarify also idx since the index is within the function of the GPIO consumer
device and not within the device itself only.

3cc6919bd6 backlight: Add backlight device (un)registration notification
Some firmware drivers, ie acpi-video want to get themselves out of the
way (in some cases) when their also is a raw backlight device available.

Due to module loading ordering being unknown, acpi-video cannot be certain
that the backlight_device_registered(BACKLIGHT_RAW) it does for this is
the final verdict wrt there being a BACKLIGHT_RAW device.

By adding notification acpi-video can listen for backlight devices showing
up after it has loaded, and unregister its backlight device if desired.

f025d3b9c6 ASoC: jack: Add support for GPIO descriptor defined jack pins
Allow jack GPIO pins be defined also using GPIO descriptor-based interface
in addition to legacy GPIO numbers. This is done by adding two new fields to
struct snd_soc_jack_gpio: idx and gpiod_dev.

Legacy GPIO numbers are used only when GPIO consumer device gpiod_dev is
NULL and otherwise idx is the descriptor index within the GPIO consumer
device.

New function snd_soc_jack_add_gpiods() is added for typical cases where all
GPIO descriptor jack pins belong to same GPIO consumer device. For other
cases the caller must set the gpiod_dev in struct snd_soc_jack_gpio before
calling snd_soc_jack_add_gpios().

45fef5b88d ACPI: add dynamic_debug support
Commit 1a699476e2 ("ACPI / hotplug / PCI: Hotplug notifications
from acpi_bus_notify()") added debug messages for a few common
events. These debug messages are unconditionally enabled if
CONFIG_DYNAMIC_DEBUG is defined, contrary to the documented
meaning, making the ACPI system spew lots of unwanted noise on
any kernel with dynamic debugging.

The bug was introduced by commit fbfddae696 ("ACPI: Add
acpi_handle_<level>() interfaces"), which added the
CONFIG_DYNAMIC_DEBUG dependency without respecting its meaning.

Fix by adding real support for dynamic_debug.

9b1ee0b2cb ALSA: firewire/bebob: Add a workaround for M-Audio special Firewire series
In post commit, a quirk of this firmware about transactions is reported.
This commit apply a workaround for this quirk.

They often fail transactions due to gap_count mismatch. This state is changed
by generating bus reset.

The fw_schedule_bus_reset() is an exported symbol in firewire-core. But there
are no header for public. This commit moves its prototype from
drivers/firewire/core.h to include/linux/firewire.h.

This mismatch still affects bus management before generating this bus reset.
It still takes a time to call driver's probe() because transactions are still
often failed.

555e8a8f7f ALSA: fireworks: Add command/response functionality into hwdep interface
This commit adds two functionality for hwdep interface, adds two parameters for
this driver, add a node for proc interface.

To receive responses from devices, this driver already allocate own callback
into initial memory space in host controller. This means no one can allocate
its own callback to the address. So this driver must give a way for user
applications to receive responses.

This commit adds a functionality to receive responses via hwdep interface. The
application can receive responses to read from this interface. To achieve this,
this commit adds a buffer to queue responses. The default size of this buffer is
1024 bytes. This size can be changed to give preferrable size to
'resp_buf_size' parameter for this driver. The application should notice rest
of space in this buffer because this driver don't push responses when this
buffer has no space.

Additionaly, this commit adds a functionality to transmit commands via hwdep
interface. The application can transmit commands to write into this interface.
I note that the application can transmit one command at once, but can receive
as many responses as possible untill the user-buffer is full.

When using these interfaces, the application must keep maximum number of
sequence number in command within the number in firewire.h because this driver
uses this number to distinguish the response is against the command by the
application or this driver.

Usually responses against commands which the application transmits are pushed
into this buffer. But to enable 'resp_buf_debug' parameter for this driver, all
responses are pushed into the buffer. When using this mode, I reccomend to
expand the size of buffer.

Finally this commit adds a new node into proc interface to output status of the
buffer.

fbebf59778 ARM: 8057/1: amba: Add Qualcomm vendor ID.
This patch adds Qualcomm amba vendor Id to the list. This ID is used in mmci driver. The ID selected in same lines like 0x41 is "A" for ARM, 0x51 is "Q" for Qualcomm.

As there are no physical register on Qcom SOC for amba vendor id, this is a fake ID assigned based on "Q" prefix from Qualcomm.

Pull networking fixes from David Miller:
 "It looks like a sizeble collection but this is nearly 3 weeks of bug
  fixing while you were away.

   1) Fix crashes over IPSEC tunnels with NAT, the latter can reroute
      the packet through a non-IPSEC protected path and the code has to
      be able to handle SKBs attached to routes lacking an attached xfrm
      state.  From Steffen Klassert.

   2) Fix OOPSs in ipv4 and ipv6 ipsec layers for unsupported
      sub-protocols, also from Steffen Klassert.

   3) Set local_df on fragmented netfilter skbs otherwise we won't be
      able to forward successfully, from Florian Westphal.

   4) cdc_mbim ipv6 neighbour code does __vlan_find_dev_deep without
      holding RCU lock, from Bjorn Mork.

   5) local_df test in ip_may_fragment is inverted, from Florian
      Westphal.

   6) jme driver doesn't check for DMA mapping failures, from Neil
      Horman.

   7) qlogic driver doesn't calculate number of TX queues properly, from
      Shahed Shaikh.

   8) fib_info_cnt can drift irreversibly positive if we fail to
      allocate the fi->fib_metrics array, from Sergey Popovich.

   9) Fix use after free in ip6_route_me_harder(), also from Sergey
      Popovich.

  10) When SYSCTL is disabled, we don't handle local_port_range and
      ping_group_range defaults properly at all, from Cong Wang.

  11) Unaccelerated VLAN tagged frames improperly handled by cdc_mbim
      driver, fix from Bjorn Mork.

  12) cassini driver needs nested lock annotations for TX locking, from
      Emil Goode.

  13) On init error ipv6 VTI driver can unregister pernet ops twice,
      oops.  Fix from Mahtias Krause.

  14) If macvlan device is down, don't propagate IFF_ALLMULTI changes,
      from Peter Christensen.

  15) Missing NULL pointer check while parsing netlink config options in
      ip6_tnl_validate().  From Susant Sahani.

  16) Fix handling of neighbour entries during ipv6 router reachability
      probing, from Duan Jiong.

  17) x86 and s390 JIT address randomization has some address
      calculation bugs leading to crashes, from Alexei Starovoitov and
      Heiko Carstens.

  18) Clear up those uglies with nop patching and net_get_random_once(),
      from Hannes Frederic Sowa.

  19) Option length miscalculated in ip6_append_data(), fix also from
      Hannes Frederic Sowa.

  20) A while ago we fixed a race during device unregistry when a
      namespace went down, turns out there is a second place that needs
      similar protection.  From Cong Wang.

  21) In the new Altera TSE driver multicast filtering isn't working,
      disable it and just use promisc mode until the cause is found.
      From Vince Bridgers.

  22) When we disable router enabling in ipv6 we have to flush the
      cached routes explicitly, from Duan Jiong.

  23) NBMA tunnels should not cache routes on the tunnel object because
      the key is variable, from Timo Teräs.

  24) With stacked devices GRO information in skb->cb[] can be not setup
      properly, make sure it is in all code paths.  From Eric Dumazet.

  25) Really fix stacked vlan locking, multiple levels of nesting with
      intervening non-vlan devices are possible.  From Vlad Yasevich.

  26) Fallback ipip tunnel device's mtu is not setup properly, from
      Steffen Klassert.

  27) The packet scheduler's tcindex filter can crash because we
      structure copy objects with list_head's inside, oops.  From Cong
      Wang.

  28) Fix CHECKSUM_COMPLETE handling for ipv6 GRE tunnels, from Eric
      Dumazet.

  29) In some configurations 'itag' in __mkroute_input() can end up
      being used uninitialized because of how fib_validate_source()
      works.  Fix it by explitly initializing itag to zero like all the
      other fib_validate_source() callers do, from Li RongQing"

Here is version 4 of platform support for AXM5516 SoC.

The clk driver is now applied to clk-next. The rest should be ready for

this driver can be taken via arm-soc as well.

The AXM55xx family consists of devices that may contain up to 16 ARM Cortex-A15
cores (in a 4x4 cluster configuration). The cores within each cluster share an
L2 cache, and the clusters are connected to each other via a CCN-504 cache
coherent interconnect.

This machine requires CONFIG_ARM_LPAE enabled as all peripherals are located
above 4GB in the memory map.

moves resolving of the interrupt resources in platform_get_irq().
But this solution isn't complete because platform_get_irq_byname()
need to be modified the same way.

Hence, fix it by adding interrupt resolution code at the
platform_get_irq_byname() function too.

usb: patches for v3.16 merge window

Not a lot here during this merge window. Mostly we just have
the usual miscellaneous patches (removal of unnecessary prints,
proper dependencies being added to Kconfig, build warning fixes,
new device ID, etc.

Other than those, the only important new features are the
new support for OS Strings which should help Linux Gadget
Drivers behave better under MS Windows. Also Babble Recovery
implementation for MUSB on AM335x. Lastly, we also have
ARCH_QCOM PHY support though phy-msm.
