MyungJoo Ham 6e0414a5c8 regulator: max8997: remove dependency on platform_data pointer
The platform_data (pdata) may be pointing to __initdata section, which
may be free'd from the memory. The dependency on pdata in non-init
functions is removed in this patch to allow platform to declare
__initdata for platform data.

Tushar Behera dbb48e7c3d regulator: MAX8997: Fix for divide by zero error
Currently, ramp_delay variable is used uninitialzed in
max8997_set_voltage_ldobuck which gets called through
regulator_register calls.

To fix the problem, in max8997_pmic_probe, ramp_delay initialization
code is moved before calls to regulator_register.

Alex Deucher b7eff39467 drm/radeon/kms: clean up multiple crtc handling for evergreen+ (v2)
evergreen+ asics have 2-6 crtcs.  Don't access crtc registers
for crtc regs that don't exist as they have very high latency
and may cause problems on some asics.  The previous code missed
a few cases and was not fine grained enough (missed the 4 crtc
case for example).

Mathias Nyman 2345b20fd9 gpio/langwell_gpio: ack the correct bit for langwell gpio interrupts
The wrong bit was masked when acking langwell gpio interrupts.

Reason for maskig the wrong bit was probably because__ffs() and ffs() functions
return bit indexes differently (0..31 vs 1..32)

This fixes langwell based devices from hanging when a gpio interrupt is
triggered and undoes the breakage which occurred in change set

Alan Stern ca5c485f55 USB: additional regression fix for device removal
Commit e534c5b831 (USB: fix regression
occurring during device removal) didn't go far enough.  It failed to
take into account that when a driver claims multiple interfaces, it may
release them all at the same time.  As a result, some interfaces can
get released before they are unregistered, and we deadlock trying to
acquire the bandwidth_mutex that we already own.

This patch (asl478) handles this case by setting the "unregistering"
flag on all the interfaces before removing any of them.

David Howells c902ce1bfb FS-Cache: Add a helper to bulk uncache pages on an inode
Add an FS-Cache helper to bulk uncache pages on an inode.  This will
only work for the circumstance where the pages in the cache correspond
1:1 with the pages attached to an inode's page cache.

This is required for CIFS and NFS: When disabling inode cookie, we were
returning the cookie and setting cifsi->fscache to NULL but failed to
invalidate any previously mapped pages.  This resulted in "Bad page
state" errors and manifested in other kind of errors when running
fsstress.  Fix it by uncaching mapped pages when we disable the inode
cookie.

This patch should fix the following oops and "Bad page state" errors
seen during fsstress testing.

The subdevs are supposed to receive a valid tuner type for the g_frequency
and g/s_tuner subdev ops. Some drivers do this, others don't. So prefill
this in v4l2-ioctl.c based on whether the device node from which this is
called is a radio node or not.

The spec does not require applications to fill in the type, and if they
leave it at 0 then the 'check_mode' call in tuner-core.c will return
an error and the ioctl does nothing.

Hans Verkuil 9bf0ef060e [media] tuner-core: fix tuner_resume: use t->mode instead of t->type
set_mode is called with t->type, which is the tuner type. Instead, use
t->mode which is the actual tuner mode (i.e. radio vs tv).

Hans Verkuil 4e4a31fb95 [media] tuner-core: fix s_std and s_tuner
Both s_std and s_tuner are broken because set_mode_freq is called before the
new std (for s_std) and audmode (for s_tuner) are set.

This patch splits set_mode_freq in a set_mode and a set_freq and in s_std/s_tuner
first calls set_mode, and if that returns 0 (i.e. the mode is supported)
then they set t->std/t->audmode and call set_freq.

This fixes a bug where changing std or audmode would actually change it to
the previous value.

Discovered while testing analog TV standards for cx18 with a tda18271 tuner.

Konrad Rzeszutek Wilk ee339fe63a xen/pci: Move check for acpi_sci_override_gsi to xen_setup_acpi_sci.
Previously we would check for acpi_sci_override_gsi == gsi every time
a PCI device was enabled. That works during early bootup, but later
on it could lead to triggering unnecessarily the acpi_gsi_to_irq(..) lookup.
The reason is that acpi_sci_override_gsi was declared in __initdata and
after early bootup could contain bogus values.

This patch moves the check for acpi_sci_override_gsi to the
site where the ACPI SCI is preset.

Henrique de Moraes Holschuh a50245af78 thinkpad-acpi: handle HKEY 0x4010, 0x4011 events
Handle events 0x4010 and 0x4011 so that we do not pester users about them.

These events report when the thinkpad is docked/undocked to a native
hotplug dock (i.e. one that does not need ACPI handling, nor is represented
in the ACPI device tree).  Such docks are based on USB 2.0/3.0, and also
work as port replicators.

We really want a proper dock class to report these, or at least new input
EV_SW events.  Since it is not clear which one to use yet, keep reporting
them as vendor-specific ThinkPad events.

WARNING: As defined by the thinkpad-acpi sysfs ABI rules of engagement, the
vendor-specific events will be REMOVED as soon as generic events are made
available (duplicate events are a big problem), with an appropriate update
to the thinkpad-acpi sysfs/event ABI versioning.  Userspace is already
prepared to provide easy backwards compatibility for such changes when
convenient to the distro (see acpi-fakekey).

* Event 0x4010: docking to hotplug dock/port replicator
* Event 0x4011: undocking from hotplug dock/port replicator

Typical usecase would be to trigger display reconfiguration.

Reports mention T410, T510, and series 3 docks/port replicators.  Special
thanks to Robert de Rooy for his extensive report and analysis of the
situation.

Henrique de Moraes Holschuh 2d43f671c8 thinkpad-acpi: handle some new HKEY 0x60xx events
Handle some user interface events from the newer Lenovo models.  We are likely
to do something smart with these events in the future, for now, hide the ones
we are already certain about from the user and userspace both.

* Events 0x6000 and 0x6005 are key-related.  0x6005 is not properly identified
  yet.  Ignore these events, and do not report them.

* Event 0x6040 has not been properly identified yet, and we don't know if it
  is important (looks like it isn't, but still...).  Keep reporting it.

* Change the message the driver outputs on unknown 0x6xxx events, as all
  recent events are not related to thermal alarms.  Degrade log level from
  ALERT to WARNING.

Thanks to all users who reported these events or asked about them in a number
of mailing lists.  Your help is highly appreciated, even if I did took a lot of
time to act on them.  For that I apologise.

I will list those that identified the reasons for the events as "reported-by",
and I apologise in advance if I leave anyone out: it was not done on purpose, I
made the mistake of not properly tagging all event report emails separately,
and might have missed some.

acer-wmi is indiscriminately using the device state from hotkey
events to update the various rfkill states. On the Aspire 1830 this
can result in a soft block on the wlan when the touchpad hotkey is
pressed, as it is reporting a non-zero device state that does not
reflect the wireless status. To fix this, only update rfkill states
when a wlan or bluetooth hotkey is pressed.

Vitaly Kuzmichev 90c5ffe592 ARM: 6994/1: smp_twd: Fix typo in 'twd_timer_rate' printing
To get hundredths of MHz the rate needs to be divided by 10'000.
Here is an example:
 twd_timer_rate = 123456789
 Before the patch:
    twd_timer_rate / 1000000 = 123
    (twd_timer_rate / 1000000) % 100 = 23
    Result: 123.23MHz.
 After being fixed:
    twd_timer_rate / 1000000 = 123
    (twd_timer_rate / 10000) % 100 = 45

Matthew Garrett f70e957cda x86: Don't use the EFI reboot method by default
Testing suggests that at least some Lenovos and some Intels will
fail to reboot via EFI, attempting to jump to an unmapped
physical address. In the long run we could handle this by
providing a page table with a 1:1 mapping of physical addresses,
but for now it's probably just easier to assume that ACPI or
legacy methods will be present and reboot via those.

Sometimes we could be controlling a device (such as an NVIDIA Tesla) that
has no crtcs/encoders/connectors.

One could argue that the driver should unset DRIVER_MODESET in this case,
but that changes a whole heap of the DRM's other behaviours, and it's much
easier to just be a modesetting driver without any outputs.
