 "Driver updates for ARM SoCs.  Some for SoC-family code under

  anywhere else.  We also bring in the drivers/reset code through
  arm-soc.

  Some of the larger updates:

   - Qualcomm support for SMEM, SMSM, SMP2P.  All used to communicate
     with other parts of the chip/board on these platforms, all
     proprietary protocols that don't fit into other subsystems and live
     in drivers/soc for now.

   - System bus driver for UniPhier

   - Driver for the TI Wakeup M3 IPC device

   - Power management for Raspberry PI

 "As usual, a bunch of commits, mostly adding drivers and other options

  allow building a shared kernel for all boards.  With this, we can
  hopefully remove a bunch of individual defconfigs down the road but it

Pull ARM SoC multiplatform code updates from Arnd Bergmann:
 "This branch is the culmination of 5 years of effort to bring the ARMv6
  and ARMv7 platforms together such that they can all be enabled and
  boot the same kernel.  It has been a tremendous amount of cleanup and
  refactoring by a huge number of people, and creation of several new
  (and major) subsystems to better abstract out all the platform details
  in an appropriate manner.

  The bulk of this branch is a large patchset from Arnd that brings
  several of the more minor and older platforms we have closer to
  multiplatform support.  Among these are MMP, S3C64xx, Orion5x, mv78xx0
  and realview Much of this is moving around header files from old mach
  directories, but there are also some cleanup patches of debug_ll
  (lowlevel debug per-platform options) and other parts.

  Linus Walleij also has some patchs to clean up the older ARM Realview
  platforms by finally introducing DT support, and Rob Herring has some
  for ARM Versatile which is now DT-only.  Both of these platforms are
  now multiplatform.

  Finally, a couple of patches from Russell for Dove PMU, and a fix from
  Valentin Rothberg for Exynos ADC, which were rebased on top of the
  series to avoid conflicts"

 "My PowerBook G4 Aluminum with a 32-bit PPC processor fails to boot for
  the 4.4-git series".

This is likely due to X still needing /dev/mem access on this platform.

CONFIG_STRICT_DEVMEM=y.

Remove the default so that old configurations do not change behavior.

A newly added tracepoint in the hugepage code uses a variable in the
error handling that is not initialized at that point:

include/trace/events/huge_memory.h:81:230: error: 'isolated' may be used uninitialized in this function [-Werror=maybe-uninitialized]

The result is relatively harmless, as the trace data will in rare
cases contain incorrect data.

This works around the problem by adding an explicit initialization.

A recent bug fix added code that does

        bool logged_out = (status & 0xFFFF);
        if (logged_out == CTIO_PORT_LOGGED_OUT)
		...

This looks wrong because we are comparing a boolean with an
integer constant, ang gcc warns about it accordingly:

drivers/scsi/qla2xxx/qla_target.c: In function 'qlt_do_ctio_completion':
drivers/scsi/qla2xxx/qla_target.c:3587:20: warning: comparison of constant '41' with boolean expression is always false [-Wbool-compare]
        (logged_out == CTIO_PORT_LOGGED_OUT) ?

The correct fix is presumably to make that variable an 'int'.

This patch addresses a long standing race where obtaining
se_node_acl->acl_kref in __transport_register_session()
happens a bit too late, and leaves open the potential
for core_tpg_del_initiator_node_acl() to hit a NULL
pointer dereference.

Instead, take ->acl_kref in core_tpg_get_initiator_node_acl()
while se_portal_group->acl_node_mutex is held, and move the
final target_put_nacl() from transport_deregister_session()
into transport_free_session() so that fabric driver login
failure handling using the modern method to still work
as expected.

Also, update core_tpg_get_initiator_node_acl() to take
an extra reference for dynamically generated acls for
demo-mode, before returning to fabric caller.  Also
update iscsi-target sendtargets special case handling
to use target_tpg_has_node_acl() when checking if
demo_mode_discovery == true during discovery lookup.

Note the existing wait_for_completion(&acl->acl_free_comp)
in core_tpg_del_initiator_node_acl() does not change.

This patch converts core_tpg_set_initiator_node_queue_depth()
to use struct se_node_acl->acl_sess_list when performing
explicit se_tpg_tfo->shutdown_session() for active sessions,
in order for new se_node_acl->queue_depth to take effect.

This follows how core_tpg_del_initiator_node_acl() currently
works when invoking se_tpg_tfo->shutdown-session(), and ahead
of the next patch to take se_node_acl->acl_kref during lookup,
the extra get_initiator_node_acl() can go away. In order to
achieve this, go ahead and change target_get_session() to use
kref_get_unless_zero() and propigate up the return value
to know when a session is already being released.

This is because se_node_acl->acl_group is already protecting
se_node_acl->acl_group reference via configfs, and shutdown
within core_tpg_del_initiator_node_acl() won't occur until
sys_write() to core_tpg_set_initiator_node_queue_depth()
attribute returns back to user-space.

Also, drop the left-over iscsi-target hack, and obtain
se_portal_group->session_lock in lio_tpg_shutdown_session()
internally. Remove iscsi-target wrapper and unused se_tpg +
force parameters and associated code.

This patch is a iscsi-target specific bug-fix for a dead-lock
that can occur during explicit struct se_node_acl->acl_group
se_session deletion via configfs rmdir(2), when iscsi-target
time2retain timer is still active.

It changes iscsi-target to obtain se_portal_group->session_lock
internally using spin_in_locked() to check for the specific
se_node_acl configfs shutdown rmdir(2) case.

Note this patch is intended for stable, and the subsequent
v4.5-rc patch converts target_core_tpg.c to use proper
se_sess->sess_kref reference counting for both se_node_acl
deletion + se_node_acl->queue_depth se_session restart.

Intel PM Telemetry is a software mechanism via which various SoC
PM and performance related parameters like PM counters, firmware
trace verbosity, the status of different devices inside the SoC, etc.
can be monitored and analyzed. The different samples that may be
monitored can be configured at runtime via exported APIs.

This patch adds the telemetry core driver that implements basic
exported APIs.

BIOS/ACPI on devices with WMI interface version 0 does not clear buffer
before filling it. So next time when BIOS/ACPI send WMI event which is
smaller as previous then it contains garbage in buffer from previous event.

BIOS/ACPI on devices with WMI interface version 1 clears buffer and
sometimes send more events in buffer at one call.

Since commit 83fc44c3 ("dell-wmi: Update code for processing WMI
events") dell-wmi process all events in buffer (and not just first).

To prevent reading garbage from the buffer we process only the first
event on devices with WMI interface version 0.

Some Asus notebooks like the Asus E202SA and the Asus X555UB have a
separate ACPI device for notifications from the airplane mode hotkey.
This device is called "Wireless Radio Control" in Asus websites and ASHS
in the DSDT, and its ACPI _HID is ATK4002 in the two models mentioned
above.

For these models, when the airplane mode hotkey (Fn+F2) is pressed, a
query 0x0B is started in the Embedded Controller, and all this query does
is a notify ASHS with the value 0x88 (for acpi_osi >= "Windows 2012"):
