Pull x86 platform driver updates from Matthew Garrett:
 "A moderate number of changes, but nothing awfully significant.

  A lot of const cleanups, some reworking and additions to the rfkill
  quirks in the asus driver, a new driver for generating falling laptop
  events on Toshibas and some misc fixes.

  Maybe vendors have stopped inventing things"

23d0ba0c90 platform/x86: Toshiba HDD Active Protection Sensor
This driver adds support for the built-in accelereometer found
on recent Toshiba laptops with HID TOS620A.

This driver receives ACPI notify events 0x80 when the sensor
detects a sudden move or a harsh vibration, as well as an
ACPI notify event 0x81 whenever the movement or vibration has
been stabilized.

Also provides sysfs entries to get/set the desired protection
level and reseting the HDD protection interface.

f6aac65229 toshiba_acpi: Add extra check to backlight code
Some Toshiba models (most notably Qosmios) come with an
incomplete backlight method where the AML code doesn't
check for write or read commands and always returns
HCI_SUCCESS and the actual brightness (and in some
cases the max brightness), thus allowing the backlight
interface to be registered without write support.

This patch changes the set_lcd_brightness function,
checking the returned values for values greater than
zero to avoid registering a broken backlight interface.

959ef6d5de WMI: Remove unnecessary null test
This patch removes the null test on block. block is initialized at the
beginning of the function to &wblock->gblock. Since wblock is
dereferenced prior to the null test, wblock must be a valid pointer,
and &wblock->gblock cannot be null.

The following Coccinelle script is used for detecting the change:

86ac2735ae asus-wmi: backlight_init: Stop treating -ENODEV as if its not an error
When bl_power support got added to asus-wmi, the error handling for it was
written to ignore -ENODEV, to avoid not registering a backlight interface for
models which have no bl_power control, but do have brightness control.

At the same time the error handling for brightness_max was modified to do the
same, this is wrong, when there is no brightness_max asus-wmi should not
register a backlight interface.

Note the caller of asus_wmi_backlight_init already special cases -ENODEV,
and will not cause the wmi driver regristration to fail because of a
-ENODEV return from asus_wmi_backlight_init.

ce363c2bcb ideapad-laptop: Change Lenovo Yoga 2 series rfkill handling
It seems that the same problems which lead to adding an rfkill blacklist and
putting the Lenovo Yoga 2 11 on it are also present on the Lenovo Yoga 2 13
and Lenovo Yoga 2 Pro too:
https://bugzilla.redhat.com/show_bug.cgi?id=1021036
https://forums.lenovo.com/t5/Linux-Discussion/Yoga-2-13-not-Pro-Linux-Warning/m-p/1517612

Testing has shown that the firmware rfkill settings are persistent over
reboots. So blacklisting the driver is not good enough, if the wifi is blocked
at the firmware level the wifi needs to be explictly unblocked through the
ideapad-laptop interface.

And at least on the Lenovo Yoga 2 13 the VPCCMD_RF register which on devices
with hardware kill switch reports the hardware switch state, needs to be
explictly set to 1 (radio enabled / not blocked).

So this patch does 3 things to get proper rfkill handling on these models:

1) Instead of blacklisting the rfkill functionality, which means that people
with a firmware blocked wifi get stuck in that situation, ignore the value
reported by the not present hardware rfkill switch, as this is what is causing
ideapad-laptop to wrongly report all radios as hardware blocks. But do register
the rfkill interfaces so that the user can soft [un]block them.

2) On models without a hardware rfkill switch, explictly set VPCCMD_RF to 1

3) Drop the " 11" postfix from the dmi match string, as the entire Yoga 2
series is affected.

Pull more SCSI changes from James Bottomley:
 "This is a small set of updates which missed the first pull.  It's more
  msix updates, some iscsi and qla4xxx fixes, we also have some string
  null termination fixes a return value fix and a couple of pm8001
  firmware fixes.

  Just a note, we do have a couple of bug fixes coming under separate
  cover, but they don't have to be part of the merge window"

a138b56800 intel_idle: Broadwell support
Broadwell (BDW) is similar to Haswell (HSW), the preceding processor generation.

Currently, the only difference in their C-state tables is that PC3 max exit latency
is 33usec on HSW and 40usec on BDW.

34679ec7a0 virtio: rng: add derating factor for use by hwrng core
The khwrngd thread is started when a hwrng device of sufficient
quality is registered.  The virtio-rng device is backed by the
hypervisor, and we trust the hypervisor to provide real entropy.

A malicious or badly-implemented hypervisor is a scenario that's
irrelevant -- such a setup is bound to cause all sorts of badness, and a
compromised hwrng is the least of the user's worries.

Given this, we might as well assume that the quality of randomness we
receive is perfectly trustworthy.  Hence, we use 100% for the factor,
indicating maximum confidence in the source.
