e3414b8c45 arm64: dts: renesas: salvator-common: Add GPIO keys support
The Salvator-X and XS boards have a 4 lines DIP switch and 3 push
buttons connected to SoC GPIOs, meant to be used as general-purpose test
keys. Add a corresponding node in DT, mapping (semi-randomly) the DIP
switch to keys 1-4 and the push buttons to keys A-C.

9d5549d8a8 drm/edid: Remove defunct EDID_QUIRK_FIRST_DETAILED_PREFERRED
Looks like EDID_QUIRK_FIRST_DETAILED_PREFERRED never did anything.
Its counterpart in f86EdidModes.c is properly hooked up but somehow
that functionality was lost when it was copied into the kernel.

The concensus seems to be that this quirk is a bit misguided
anyway so let's nuke the leftovers.

For posterity here are some links to known cases:

* Unknown Acer

a9282a8e69 drm/uapi: Remove unused DRM_DISPLAY_INFO_LEN
Remove the unused DRM_DISPLAY_INFO_LEN from the uapi headers.
I presume the original plan was to expose the display name
via getconnector, but looks like that never happened. So we have
the define for the length of the string but no string anywhere.

A quick scan didn't seem to reveal userspace referencing this
so hopefully we can just nuke it.

05f1d882d2 arm64: dts: renesas: r8a77995: draak: Fix EthernetAVB phy mode to rgmii
According to the R-Car Gen3 Hardware Manual Errata for Rev 1.00 of
August 24, 2018, the TX clock internal Delay mode does'nt support
on R-Car D3. This patch fixes EthernetAVB phy mode to rgmii.

This is achieved by simply dropping the phy-mode property from
r8a77995-draak.dts as the default property for this for r8a77995,
as set in r8a77995.dtsi, is "rgmii".

f19501aa07 x86/mce: Fix machine_check_poll() tests for error types
There has been a lurking "TBD" in the machine check poll routine ever
since it was first split out from the machine check handler. The
potential issue is that the poll routine may have just begun a read from
the STATUS register in a machine check bank when the hardware logs an
error in that bank and signals a machine check.

That race used to be pretty small back when machine checks were
broadcast, but the addition of local machine check means that the poll
code could continue running and clear the error from the bank before the
local machine check handler on another CPU gets around to reading it.

Fix the code to be sure to only process errors that need to be processed
in the poll code, leaving other logged errors alone for the machine
check handler to find and process.

 [ bp: Massage a bit and flip the "== 0" check to the usual !(..) test. ]

36a1da15b5 drm/omap: hdmi4_cec: Fix CEC clock handling for PM
If CONFIG_OMAP4_DSS_HDMI_CEC is enabled in .config, deeper SoC idle
states are blocked because the CEC clock gets always enabled on init.

Let's fix the issue by moving the CEC clock handling to happen later in
hdmi_cec_adap_enable() as suggested by Hans Verkuil <hverkuil@xs4all.nl>.
This way the CEC clock gets only enabled when needed. This can be tested
by doing cec-ctl --playback to enable the CEC, and doing cec-ctl --clear
to disable it.

Let's also fix the typo for "divider" in the comments while at it.

f243dd0618 drm/nouveau: Use drm_fb_helper_fill_info
This changes the fb name from "nouveaufb" to "nouveaudrmfb".

Aside: I wonder whether the in_interrupt() check is good enough for
the nouveau acceleration. Cargo-cult says drm_can_sleep() is needed,
which isn't actually working if you pick a .config without PREEMPT.
For the generic fbdev defio support we've gone with offloading
everything to a worker. For the non-accel callbacks (set_par, blank
and friends) checking for oops_in_progress is good enough to catch all
the evil calling contexts.

2583303deb gpio: mockup: fix debugfs read
The debugfs read callback must advance ppos or users using read() on
the file descriptor will never get the EOL. This wasn't spotted before
as I was using busybox cat for testing which uses sendfile() internally
and only noticed it now when switched to cat from coreutils.

f1eca684b7 drm/fb-helper: set fbi->fix.id in fill_info()
Looking at the oldest/most popular drivers ${driver}drmfb seems to be
the standard, except i915.ko went with "inteldrmfb". I guess renaming
that for consistency won't hurt, it definitely confused me when I
started with kms 10 years ago.

I hope this never became uapi ... worst case drivers can overwrite it
after having called fill_info().

Since subsequent patches change this for some drivers later on in the
series, here's the exhaustive list of where all fix.id is used:
- /proc/fb which prints the minor number and fix.id name.
- per-fb sysfs name file
- getfix ioctl, which is used by fbset only to print out the name when
dumping information
- lots and lots of places in dmesg, anytime anything happens with an
fbdev really

I think minimal to 0 chances that changing this will screw up a config
script or something, since outside of informational message it's not
used by anything to identify which fbdev maps to which minor. After
all the last fbset release is from 1999, and that predates even devfs
I think.

v2: Rebase and amend commit message, thanks to Ilia for pointing out
that this needs to be spelled out.

3df3116ab4 drm/fb-helper: Add fill_info() functions
The fbdev split between fix and var information is kinda
pointless for drm drivers since everything is fixed: The fbdev
emulation doesn't support changing modes at all.

Create a new simplified helper and use it in the generic fbdev
helper code. Follow-up patches will beef it up more and roll
it out to all drivers.

We only hit unregister_allocated_timer() if the argument to
aspeed_gpio_set_config() is 0, but we can't be calling through
gpiod_set_debounce() from gpio_keys_probe() unless the gpio-keys button has a
non-zero debounce interval.

Commit 6581eaf0e8 ("gpio: use new gpio_set_config() helper in more places")
spreads the use of gpio_set_config() to the debounce and transitory
state configuration paths. The implementation of gpio_set_config() is:

> static int gpio_set_config(struct gpio_chip *gc, unsigned offset,
> 			   enum pin_config_param mode)
> {
> 	unsigned long config = { PIN_CONF_PACKED(mode, 0) };
>
> 	return gc->set_config ? gc->set_config(gc, offset, config) : -ENOTSUPP;
> }

Here it packs its own config value with a fixed argument of 0; this is
incorrect behaviour for implementing the debounce and transitory functions, and
the debounce and transitory gpio_set_config() call-sites now have an undetected
type mismatch as they both already pack their own config parameter (i.e. what
gets passed is not an `enum pin_config_param`). Indeed this can be seen in the
small diff for 6581eaf0e8:

RISC-V: Always compile mm/init.c with cmodel=medany and notrace
The Linux RISC-V 32bit kernel is broken after we moved setup_vm() from
kernel/setup.c to mm/init.c because Linux RISC-V 32bit kernel by default
uses cmodel=medlow which results in a non-position-independent setup_vm().

This patch fixes Linux RISC-V 32bit kernel booting by:
1. Forcing cmodel=medany for mm/init.c
2. Moving remaing MM-related stuff va_pa_offset, pfn_base and
   empty_zero_page from kernel/setup.c to mm/init.c

Further, the setup_vm() cannot handle GCC instrumentation for FTRACE so
we disable it for mm/init.c by not using "-pg" compiler flag.

Fixes: 6f1e9e946f ("RISC-V: Move setup_vm() to mm/init.c")

riscv: fix accessing 8-byte variable from RV32
A memory save operation to 8-byte variable in RV32 is divided into
two sw instructions in the put_user macro.  The current fixup returns
execution flow to the second sw instead of the one after it.

This patch fixes this fixup code according to the load access part.

change aspect ratio (while keeping the existing keycodes to avoid
breaking userspace), so let's use them in the document.
