Enable runtime power management (RTPM) for PCIe devices and implement
the corresponding functions to enable D0i3 mode when the device is
idle.

Additionally, remove some unnecessary #ifdef's because the RTPM code
will not be called if runtime PM is not configured.

Add an initial implementation of runtime power management (RTPM) for
PCI devices.  With this patch, RTPM is only used when wifi is off
(i.e. the wifi interface is down).  This implementation is behind a
new Kconfig flag, IWLWIFI_PCIE_RTPM.

The 9000 series introduces several changes in the device
DMA operation.
As the device now supports multi-queue rx, several DMA channels
should be configured.
The flows of providing the device with the allocated RBDs now
changes as well - the device maintains a separate table of used
and free table.

The hardware may use the free table to feed RBDs to any queue.
This requires maintaing a shared table to map returned RBDs to
the original RXB - for that purpose the VID is introduced - an
internal identifier of the RB placed in the lower 12 bits and
returned by HW in the used data.

Another change is the support of 64 bit DMA address.

The 9000 series devices will support multi rx queues.
Current code has one static rx queue - change it to allocate
a number of queues per the device capability (pre-9000 devices
have the number of rx queues set to one).

Subsequent generalizations are:

Change the code to access an explicit numbered rx queue only
when the queue number is known - when handling interrupt, when
accessing the default queue and when iterating the queues.
The rest of the functions will receive the rx queue as a pointer.

Generalize the warning in allocation failure to consider the
allocator status instead of a single rx queue status.

Move the rx initial pool of memory buffers to be shared among
all the queues and allocated to the default queue on init.

When the Tx queues are full above a threshold, we
immediately stop the mac80211's queue to stop getting new
packets. This worked until TSO was enabled.
With TSO, one single packet from mac80211 can use many
descriptors since a large send needs to be split into
several segments.
This means that stopping mac80211's queues is not enough
and we also need to ensure that we don't overflow the Tx
queues with one single packet from mac80211.
Add code to transport layer to do just that. Stop
mac80211's queue as soon as the queue is full above the
same threshold as before, and keep pushing the current
packet along with its segments on the queue, but check
that we don't overflow. If that would happen, buffer the
segments, and send them when there is room in the Tx queue
again. Of course, we first need to send the buffered
segments and only then, wake up mac80211's queues.

Pull misc vfs updates from Al Viro:
 "All kinds of stuff.  That probably should've been 5 or 6 separate
  branches, but by the time I'd realized how large and mixed that bag
  had become it had been too close to -final to play with rebasing.

  Some fs/namei.c cleanups there, memdup_user_nul() introduction and
  switching open-coded instances, burying long-dead code, whack-a-mole
  of various kinds, several new helpers for ->llseek(), assorted
  cleanups and fixes from various people, etc.

  One piece probably deserves special mention - Neil's
  lookup_one_len_unlocked().  Similar to lookup_one_len(), but gets
  called without ->i_mutex and tries to avoid ever taking it.  That, of
  course, means that it's not useful for any directory modifications,
  but things like getting inode attributes in nfds readdirplus are fine
  with that.  I really should've asked for moratorium on lookup-related
  changes this cycle, but since I hadn't done that early enough...  I
  *am* asking for that for the coming cycle, though - I'm going to try
  and get conversion of i_mutex to rwsem with ->lookup() done under lock
  taken shared.

  There will be a patch closer to the end of the window, along the lines
  of the one Linus had posted last May - mechanical conversion of
  ->i_mutex accesses to inode_lock()/inode_unlock()/inode_trylock()/
  inode_is_locked()/inode_lock_nested().  To quote Linus back then:

    -----
    |    This is an automated patch using
    |
    |        sed 's/mutex_lock(&\(.*\)->i_mutex)/inode_lock(\1)/'
    |        sed 's/mutex_unlock(&\(.*\)->i_mutex)/inode_unlock(\1)/'
    |        sed 's/mutex_lock_nested(&\(.*\)->i_mutex,[     ]*I_MUTEX_\([A-Z0-9_]*\))/inode_lock_nested(\1, I_MUTEX_\2)/'
    |        sed 's/mutex_is_locked(&\(.*\)->i_mutex)/inode_is_locked(\1)/'
    |        sed 's/mutex_trylock(&\(.*\)->i_mutex)/inode_trylock(\1)/'
    |
    |    with a very few manual fixups

  gets mostly merged (or when Linus says he's about to stop taking
  merges)"

 "In the past, I have funnelled perf updates through the respective
  architecture trees, but now that the arm/arm64 perf driver has been
  largely consolidated under drivers/perf/, it makes more sense to send
  a separate pull, particularly as I'm listed as maintainer for all the
  files involved.  I offered the branch to arm-soc, but Arnd suggested
  that I just send it to you directly.

  So, here is the arm/arm64 perf queue for 4.5.  The main features are
  described below, but the most useful change is from Drew, which
  advertises our architected event mapping in sysfs so that the perf
  tool is a lot more user friendly and no longer requires the use of
  magic hex constants for profiling common events.

   - Support for the CPU PMU in Cortex-A72

   - Add sysfs entries to describe the architected events and their
     mappings for PMUv{1-3}"

Pull arm64 updates from Will Deacon:
 "Here is the core arm64 queue for 4.5.  As you might expect, the
  Christmas break resulted in a number of patches not making the final
  cut, so 4.6 is likely to be larger than usual.  There's still some
  useful stuff here, however, and it's detailed below.

  The EFI changes have been Reviewed-by Matt and the memblock change got
  an "OK" from akpm.

  Summary:

   - Support for a separate IRQ stack, although we haven't reduced the
     size of our thread stack just yet since we don't have enough data
     to determine a safe value

   - Refactoring of our EFI initialisation and runtime code into
     drivers/firmware/efi/ so that it can be reused by arch/arm/.

   - Ftrace improvements when unwinding in the function graph tracer

   - Document our silicon errata handling process

   - Cache flushing optimisation when mapping executable pages

Ivaylo Dimitrov reported a regression caused by commit 7866a621
("dev: add per net_device packet type chains").

skb->dev becomes NULL and we crash in __netif_receive_skb_core().

Before above commit, different kind of bugs or corruptions could happen
without major crash.

But the root cause is that phonet_rcv() can queue skb without checking
if skb is shared or not.

Many thanks to Ivaylo Dimitrov for his help, diagnosis and tests.

If bus = kzalloc() fails then we end up dereferencing bus when we do

Pull device mapper updates from Mike Snitzer:

 - The most significant set of changes this cycle is the Forward Error
   Correction (FEC) support that has been added to the DM verity target.

   Google uses DM verity on all Android devices and it is believed that
   this FEC support will enable DM verity to recover from storage
   failures seen since DM verity was first deployed as part of Android.

 - A stable fix for a race in the destruction of DM thin pool's
   workqueue

 - A stable fix for hung IO if a DM snapshot copy hit an error

 - A few small cleanups in DM core and DM persistent data.

 - A couple DM thinp range discard improvements (address atomicity of
   finding a range and the efficiency of discarding a partially mapped
   thin device)

 - Add ability to debug DM bufio leaks by recording stack trace when a
   buffer is allocated.  Upon detected leak the recorded stack is
   dumped.

Pull LED subsystem updates from Jacek Anaszewski:
 "Besides regular driver updates, we introduce a portion of LED core
  improvements, that allow to avoid the need for using work queues in
  the LED class drivers, that set brightness in a blocking way.

  Affected LED class drivers are being optimized accordingly.

   - LED core improvements:
        - use EXPORT_SYMBOL_GPL consistently,
        - add two new LED_BLINK_ flags,
        - rename brightness_set_sync op to brightness_set_blocking,
        - add led_set_brightness_nosleep{nopm} functions,
        - use set_brightness_work for the blocking op,
        - drivers shouldn't enforce SYNC/ASYNC brightness setting,
        - turn off the LED and wait for completion on unregistering LED
          class device,
        - add managed version of led_trigger_register,
        - add description of brightness setting API to the LED class doc.

   - Remove work queues from drivers: leds-tlc591xx, leds-88pm860x, leds-adp5520,
        leds-bd2802, leds-blinkm, leds-lm3533, leds-lm3642, leds-pca9532,

        leds-max77693, leds-aat1290, leds-ktd2692, leds-gpio, leds-pwm,
        leds-lm355x, leds-ns2.

   - Replace brightness_set op with a new brightness_set_blocking op to
     make the drivers compatible with led triggers: leds-ipaq-micro,
     leds-powernv.

   - Add missing of_node_put: leds-ktd2692, leds-aat1290, leds-max77693.

   - Make the driver explicitly non-modular: ledtrig-cpu,
     ledtrig-ide-disk, leds-syscon.

   - Improvements to leds-bcm6328:
        - reuse bcm6328_led_set() instead of copying its functionality,
        - swap LED ON and OFF definitions,
        - improve blink support,
        - simplify duplicated unlock in bcm6328_blink_set,
        - add little endian support,
        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - code cleaning.

   - Improvements to leds-bcm6358:
        - use bcm6358_led_set() in order to get rid of the lock,
        - merge bcm6358_led_mode and bcm6358_led_set,
        - add little endian support,
        - remove unneded lock when checking initial LED status,
        - add HAS_IOMEM dependency,
        - remove unneeded busy status check.

   - Call led_pwm_set() in leds-pwm to enforce default LED_OFF.

   - Fix duration to be msec instead of jiffies: ledtrig-transient.

   - Removing NULL check: leds-powernv.

   - Use platform_register/unregister_drivers(): leds-sunfire.

   - Fix module license specification: ledtrig-oneshot.

   - Fix driver description and make license match the header: leds-pwm.

   - Remove checking for state < 1 in flash_strobe_store():
     led-class-flash.

   - Use led_set_brightness_sync for torch brightness:
     v4l2-flash-led-class"
