ffe498237b ice: Change req_speeds to be u16
Since the req_speeds field in struct ice_link_status is a u8,
req_speeds & ICE_AQ_LINK_SPEED_40GB always returns 0. This was caught
by a coverity scan.

Fix this by changing req_speeds to be u16.

Convert drm_atomic_plane_check() over to using explicit old vs. new

534903d603 drm/atomic: Use explicit old crtc state in drm_atomic_add_affected_planes()
Replace 'crtc->state' with the explicit old crtc state.

Actually it shouldn't matter whether we use the old or the new
crtc state here since any plane that has been removed from the
crtc since the crtc state was duplicated will have been added
to the atomic state already. That is, you can't call
drm_atomic_set_crtc_for_plane() without having the new
plane state already in hand.

e09d51adfb ARM: SoC fixes
A few more fixes that have come in, and one revert of a previous fix.
 
 I was a bit too trigger happy to enable PREEMPT on multi_v7_defconfig,
 and it ended up regressing at least BeagleBone XM boards. While we get
 that debugged for next merge window, let's disable it again.
 
 Beyond that:
 
  - Stratix change to fix multicast filtering
  - Minor DT fixes for Renesas and i.MX
  - Ethernet fix for a Renesas board (switching main interfaces)
  - Ethernet phy regulator fix for i.MX6SX

spi: gpio: Support 3WIRE high-impedance turn-around
Some devices such as the TPO TPG110 display panel require
a "high-impedance turn-around", in effect a clock cycle after
switching the line from output to input mode.

Support this in the GPIO driver to begin with. Other driver
may implement it if they can, it is unclear if this can
be achieved with anything else than GPIO bit-banging.

7ce9a992ff rtc: hctosys: Add missing range error reporting
Fix an issue with the 32-bit range error path in `rtc_hctosys' where no
error code is set and consequently the successful preceding call result
from `rtc_read_time' is propagated to `rtc_hctosys_ret'.  This in turn
makes any subsequent call to `hctosys_show' incorrectly report in sysfs
that the system time has been set from this RTC while it has not.

Set the error to ERANGE then if we can't express the result due to an
overflow.

fbb974ba69 rtc: cmos: Do not export alarm rtc_ops when we do not support alarms
When there is no IRQ configured for the RTC, the rtc-cmos code does not
support alarms, all alarm rtc_ops fail with -EIO / -EINVAL.

The rtc-core expects a rtc driver which does not support rtc alarms to
not have alarm ops at all. Otherwise the wakealarm sysfs attr will read
as empty rather then returning an error, making it impossible for
userspace to find out beforehand if alarms are supported.

A system without an IRQ for the RTC before this patch:
[root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm
[root@localhost ~]#

After this patch:
[root@localhost ~]# cat /sys/class/rtc/rtc0/wakealarm
cat: /sys/class/rtc/rtc0/wakealarm: No such file or directory
[root@localhost ~]#

This fixes gnome-session + systemd trying to use suspend-then-hibernate,
which causes systemd to abort the suspend when writing the RTC alarm fails.

ARM: dts: stratix10: fix multicast filtering

On Stratix 10, the EMAC has 256 hash buckets for multicast filtering. This
needs to be specified in DTS, otherwise the stmmac driver defaults to 64
buckets and initializes the filter incorrectly. As a result, e.g. valid
IPv6 multicast traffic ends up being dropped.

55f99bf2a9 drm/i915/ringbuffer: Delay after EMIT_INVALIDATE for gen4/gen5
Exercising the gpu reloc path strenuously revealed an issue where the
updated relocations (from MI_STORE_DWORD_IMM) were not being observed
upon execution. After some experiments with adding pipecontrols (a lot
of pipecontrols (32) as gen4/5 do not have a bit to wait on earlier pipe
controls or even the current on), it was discovered that we merely
needed to delay the EMIT_INVALIDATE by several flushes. It is important
to note that it is the EMIT_INVALIDATE as opposed to the EMIT_FLUSH that
needs the delay as opposed to what one might first expect -- that the
delay is required for the TLB invalidation to take effect (one presumes
to purge any CS buffers) as opposed to a delay after flushing to ensure
the writes have landed before triggering invalidation.

The i915 driver uses shmemfs to allocate backing storage for gem
objects. These shmemfs pages can be pinned (increased ref count) by
shmem_read_mapping_page_gfp(). When a lot of pages are pinned, vmscan
wastes a lot of time scanning these pinned pages. In some extreme case,
all pages in the inactive anon lru are pinned, and only the inactive
anon lru is scanned due to inactive_ratio, the system cannot swap and
invokes the oom-killer. Mark these pinned pages as unevictable to speed
up vmscan.

Export pagevec API check_move_unevictable_pages().

This patch was inspired by Chris Wilson's change [1].

arch/x86/kernel/early-quirks.c contains special PCI quirks that need to
run even before the usual DECLARE_PCI_FIXUP_EARLY() quirks.  These have
typically been merged by the x86 maintainers, which is fine, but PCI folks

regulator: bd718x7: Remove double indirection for bd718xx_pmic_inits.rdatas
With gcc 4.1:

    drivers/regulator/bd718x7-regulator.c: In function ‘bd718xx_probe’:
    drivers/regulator/bd718x7-regulator.c:1020: warning: initialization from incompatible pointer type
    drivers/regulator/bd718x7-regulator.c:1024: warning: initialization from incompatible pointer type

Apparently this old compiler can't handle the obscure double
indirection.

However, there is no need for a double indirection.  Just store a
pointer to the array instead, like other drivers tend to do.

71b12beaf1 platform/x86: asus-nb-wmi: Drop mapping of 0x33 and 0x34 scan codes
According to Asus firmware engineers, the meaning of these codes is only
to notify the OS that the screen brightness has been turned on/off by
the EC. This does not match the meaning of KEY_DISPLAYTOGGLE /
KEY_DISPLAY_OFF, where userspace is expected to change the display
brightness.

b3f2f3799a platform/x86: asus-nb-wmi: Map 0x35 to KEY_SCREENLOCK
When the OS registers to handle events from the display off hotkey the
EC will send a notification with 0x35 for every key press, independent
of the backlight state.

The behavior of this key on Windows, with the ATKACPI driver from Asus
installed, is turning off the backlight of all connected displays with a
fading effect, and any cursor input or key press turning the backlight
back on. The key press or cursor input that wakes up the display is also
passed through to the application under the cursor or under focus.

The key that matches this behavior the closest is KEY_SCREENLOCK.

78f3ac76d9 platform/x86: asus-wmi: Tell the EC the OS will handle the display off hotkey
In the past, Asus firmwares would change the panel backlight directly
through the EC when the display off hotkey (Fn+F7) was pressed, and
only notify the OS of such change, with 0x33 when the LCD was ON and
0x34 when the LCD was OFF. These are currently mapped to
KEY_DISPLAYTOGGLE and KEY_DISPLAY_OFF, respectively.

Most recently the EC on Asus most machines lost ability to toggle the
LCD backlight directly, but unless the OS informs the firmware it is
going to handle the display toggle hotkey events, the firmware still
tries change the brightness through the EC, to no effect. The end result
is a long list (at Endless we counted 11) of Asus laptop models where
the display toggle hotkey does not perform any action. Our firmware
engineers contacts at Asus were surprised that there were still machines
out there with the old behavior.

Calling WMNB(ASUS_WMI_DEVID_BACKLIGHT==0x00050011, 2) on the _WDG device
tells the firmware that it should let the OS handle the display toggle
event, in which case it will simply notify the OS of a key press with
0x35, as shown by the DSDT excerpts bellow.
