6759dc3238 ALSA: hda/realtek - Fix missing inits of item indices for auto-mic
When the imux entries are rebuilt in alc_rebuild_imux_for_auto_mic(),
the initialization of index field is missing.  It may work without it
casually when the original imux was created by the auto-parser, but
it's definitely broken in the case of static configs where no imux was
parsed beforehand.  Because of this, the auto-mic switching doesn't
work properly on some model options.

This patch adds the missing initialization of index field.

6dfeb703e3 ALSA: hda - Fix invalid pin and GPIO for Apple laptops with CS codecs
The PCI SSID 8086:7270 is commonly used for multiple Apple machines,
thus we can't use it as identifier for a unique model.  Because of this
conflict, some machines show weird behavior.  For example, MacBook Air
shows Front and Surround speakers although only Surround works due to
the wrongly overridden pin-configuration for imac27.

This patch fixes two things:
- Stop the wrong pin-config override of imac27 by removing PCI SSID
  entry for avoiding the wrong mappings,
- Add the generic GPIO setup for Apple machines by checking the codec
  SSID vendor bits

6a8943d9ec rtc: Fix some bugs that allowed accumulating time drift in suspend/resume
The current code checks if abs(delta_delta.tv_sec) is greater or
equal to two before it discards the old delta value, but this can
trigger at close to -1 seconds since -1.000000001 seconds is stored
as tv_sec -2 and tv_nsec 999999999 in a normalized timespec.

rtc_resume had an early return check if the rtc value had not changed
since rtc_suspend. This effectivly stops time for the duration of the
short sleep. Check if sleep_time is positive after all the adjustments
have been applied instead since this allows the old_system adjustment
in rtc_suspend to have an effect even for short sleep cycles.

c0afabd3d5 rtc: Disable the alarm in the hardware
Currently, the RTC code does not disable the alarm in the hardware.

This means that after a sequence such as the one below (the files are in the
RTC sysfs), the box will boot up after 2 minutes even though we've
asked for the alarm to be turned off.

	# echo $((`cat since_epoch`)+120) > wakealarm
	# echo 0 > wakealarm
	# poweroff

Fix this by disabling the alarm when there are no timers to run.

7c8f424798 md/lock: ensure updates to page_attrs are properly locked.
Page attributes are set using __set_bit rather than set_bit as
it normally called under a spinlock so the extra atomicity is not
needed.

However there are two places where we might set or clear page
attributes without holding the spinlock.
So add the spinlock in those cases.

This might be the cause of occasional reports that bits a aren't
getting clear properly - theory is that BITMAP_PAGE_PENDING gets lost
when BITMAP_PAGE_NEEDWRITE is set or cleared.  This is an
inconvenience, not a threat to data safety.

b4bbb02934 Revert "of/irq: of_irq_find_parent: check for parent equal to child"
This reverts commit dc93728084.

As requested by Ben Herrenschmidt:
  "This breaks some powerpc platforms at least.  The practice of having
   a node provide an explicit "interrupt-parent" property pointing to
   itself is an old trick that we've used in the past to allow a
   device-node to have interrupts routed to different controllers.

   In that case, the node also contains an interrupt-map, so the node is
   its own parent, the interrupt resolution hits the map, which then can
   route each individual interrupt to a different parent."

Grant says:
  "Ah, nuts, yes that is broken then.  Yes, please revert the commit and
   Rob & I will come up with a better solution.

   Rob, I think it can be done by explicitly checking for np ==
   desc->interrupt_parent in of_irq_init() instead of relying on
   of_irq_find_parent() returning NULL."

Motion+ reports rotation gyro data which we report to userspace as ABS_RX/Y/Z
values. The device reports them either in fast or slow mode. We adjust the
values to get a linear scale so userspace does not need to know about slow and

The motion+ also reports whether an extension is connected to it. We keep track
of this value and reinitialize the extensions if an extension is plugged or
unplugged.

cb99221ba7 HID: wiimote: Add extension support stub
The wiimote supports several extensions. This adds a separate source file which
handles all extensions and can be disabled at compile-time.

The driver reacts on "plug"-events on the extension port and starts a worker
which initializes or deinitializes the extensions.

Currently, the initialization logic is not fully understood and we can only
detect and enable all extensions when all extensions are deactivated. Therefore,
we need to disable all extensions, then detect and activate them again to react
on "plug"-events.
However, deactivating extensions will generate a new "plug"-event and we will
never leave that loop. Hence, we only support extensions if they are plugged
before the wiimote is connected (or before the ext-input device is opened). In
the future we may support full extension hotplug support, but
reverse-engineering this may take a while.
