47d263a6d8 drm/i915/adl_p: Extend PLANE_WM bits for blocks & lines
ADL-P further extends the bits in PLANE_WM that represent blocks and
lines; we need to extend our masks accordingly.  Since these bits are
reserved and MBZ on earlier platforms, it's safe to use the larger
bitmask on all platforms.

1003cee29f drm/i915/xelpd: Increase maximum watermark lines to 255
XE_LPD continues to use the same "skylake-style" watermark
programming as other recent platforms.  The only change to the watermark
calculations compared to Display12 is that XE_LPD now allows a
maximum of 255 lines vs the old limit of 31.

Due to the larger possible lines value, the corresponding bits
representing the value in PLANE_WM are also extended, so make sure we
read/write enough bits.  Let's also take this opportunity to switch over
to the REG_FIELD notation.

ed2615a855 drm/i915/xelpd: Handle new location of outputs D and E
The DDI naming template for display version 12 went A-C, TC1-TC6.  With
XE_LPD, that naming scheme for DDI's has now changed to A-E, TC1-TC4.

The XE_LPD design keeps the register offsets and bitfields relating to
the TC outputs in the same location they were previously.  The new "D"
and "E" outputs now take the locations that were previously used by TC5
and TC6 outputs, or what we would have considered to be outputs "H" and
"I" under the legacy lettering scheme.

For the most part everything will just work as long as we initialize the
output with the proper 'enum port' value.  However we do need to take
care to pick the correct AUX channel when parsing the VBT (e.g., a
reference to 'AUX D' is actually asking us to use the 8th aux channel,
not the fourth).  We should also make sure that our encoders and aux
channels are named appropriately so that it's easier to correlate driver
debug messages with the bspec instructions.

v2:
 - Update handling of TGL_TRANS_CLK_SEL_PORT.  (Jose)

v3:
 - Add hpd_pin to handle outputs D and E (Jose)
 - Fixed conversion of BIOS port to aux ch for TC ports (Jose)

a6922f4a01 drm/i915/xelpd: Add XE_LPD power wells
Aside from the hardware-managed PG0, XE_LPD has power wells 1-2 and
A-D.  These power wells should be enabled/disabled according to the
following dependency tree (enable top to bottom, disable bottom to top):

               PG0
                |
             --PG1--
            /       \

                 /   |   \
               PGB  PGC  PGD

PWR_WELL_CTL follows the general ICL/TGL design and places PG A-D in the
bits that would have been PG 6-9 under the old scheme.

PWR_WELL_CTL_{DDI,AUX}'s bit indexing for DDI's A-C and TC1 is the same
as TGL, but DDI-D is placed at index 7 (bits 14 & 15).

v2:
 - Squash in LPSP status patch from Uma since it's also a
   powerwell-specific change.

388b863509 drm/i915/display: Use YCbCr420 as fallback when RGB fails
When encoder validation of a display mode fails, retry with less bandwidth
heavy YCbCr420 color mode, if available. This enables some HDMI 1.4 setups
to support 4k60Hz output, which previously failed silently.

AMDGPU had nearly the exact same issue. This problem description is
therefore copied from my commit message of the AMDGPU patch.

On some setups, while the monitor and the gpu support display modes with
pixel clocks of up to 600MHz, the link encoder might not. This prevents
YCbCr444 and RGB encoding for 4k60Hz, but YCbCr420 encoding might still be
possible. However, which color mode is used is decided before the link
encoder capabilities are checked. This patch fixes the problem by retrying
to find a display mode with YCbCr420 enforced and using it, if it is
valid.

84d95f77f4 drm/i915/display: Restructure output format computation for better expandability
Couples the decission between RGB and YCbCr420 mode and the check if the
port clock can archive the required frequency. Other checks and
configuration steps that where previously done in between can also be done
before or after.

This allows for are cleaner implementation of retrying different color
encodings.

A slight change in behaviour occurs with this patch: If YCbCr420 is not
allowed but display is YCbCr420 only it no longer fails, but just prints
an error and tries to fallback on RGB.

097d9e9020 drm/i915/display: remove strap checks from gen 9
Direction on gen9+ was to stop reading the straps and only rely on the
VBT for marking the port presence. This happened while dealing with
WaIgnoreDDIAStrap and instead of using it as a WA, it should now be the
normal flow. See commit 885d3e5b6f ("drm/i915/display: fix comment on
skl straps").

For gen 10 it's hard to say if this will work or not since I can't test
it, so leave it with the same behavior as before.

For PCH_TGP we should still rely on the VBT to make ports E and F not
available.

v2 (Ville):
  - use display ver >= 9 to make it consistent with the rest of the
    driver instead of checking for == 9
  - also handle CNL and only initialize port F if it is
    IS_CNL_WITH_PORT_F. Eventually CNL may be removed, but while it
    isn't let's keep it consistent everywhere

    drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes]
    static const struct __maybe_unused seq_operations proc_fb_seq_ops = {
                        ^

Fix it.

9819f682e4 A set of scheduler updates:
- Prevent PSI state corruption when schedule() races with cgroup move.  A
    recent commit combined two PSI callbacks to reduce the number of cgroup
    tree updates, but missed that schedule() can drop rq::lock for load
    balancing, which opens the race window for cgroup_move_task() which then
    observes half updated state. The fix is to solely use task::ps_flags
    instead of looking at the potentially mismatching scheduler state
 
  - Prevent an out-of-bounds access in uclamp caused bu a rounding division
    which can lead to an off-by-one error exceeding the buckets array size.
 
  - Prevent unfairness caused by missing load decay when a task is attached
    to a cfs runqueue. The old load of the task is attached to the runqueue
    and never removed. Fix it by enforcing the load update through the
    hierarchy for unthrottled run queue instances.
 
  - A documentation fix fot the 'sched_verbose' command line option

- Two fixes for the futex syscall related to the timeout handling.
 
     FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and because
     it's not set the time namespace adjustment for clock MONOTONIC is
     applied wrongly.
 
     FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
     always a relative timeout.
 
   - Cleanups in the futex syscall entry points which became obvious when
     the two timeout handling bugs were fixed.

fec4d42724 drm/i915/display: fix compiler warning about array overrun
intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().

End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer.  gcc-11 correctly warns
about this case:

  drivers/gpu/drm/i915/display/intel_dp.c: In function ‘intel_dp_check_mst_status’:
  drivers/gpu/drm/i915/display/intel_dp.c:3491:22: warning: ‘drm_dp_channel_eq_ok’ reading 6 bytes from a region of size 4 [-Wstringop-overread]

        |      ^~~~~~~~~~~~~~~~~~~~
       6:14 elapsed

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.

There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use
random data off the stack.

c1f8a398b6 smb3: if max_channels set to more than one channel request multichannel
Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

0ab1438bad linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>
<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.

IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.

Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.

Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

f96271cefe Merge branch 'master' into next
Merge master back into next, this allows us to resolve some conflicts in
arch/powerpc/Kconfig, and also re-sort the symbols under config PPC so
that they are in alphabetical order again.

====================
Intel Wired LAN Driver Updates 2021-05-07

This series contains updates to i40e driver only.

Magnus fixes XDP by adding and correcting checks that were caused by a
previous commit which introduced a new variable but did not account for
it in all paths.

Yunjian Wang adds a return in an error path to prevent reading a freed
pointer.

Jaroslaw forces link reset when changing FEC so that changes take
affect.

Mateusz fixes PHY types for 2.5G and 5G as there is a differentiation on
PHY identifiers based on operation.

Arkadiusz removes filtering of LLDP frames for software DCB as this is
preventing them from being properly transmitted.

* '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/net-queue:
  i40e: Remove LLDP frame filters
  i40e: Fix PHY type identifiers for 2.5G and 5G adapters
