In multiple parts of the DCN code, we write directly to the
OTG_V_TOTAL_* registers in some OPTC functions. Let's avoid it by using
the set_vtotal_min_max.

The struct timing_generator_funcs provides a hook for setting up the
maximum possible vertical dimension of display for OTG, as the panel
supports. DCN10 has a standard function named optc1_set_vtotal_min_max
which all ASICs can use to set the aforementioned hook. Since we did not
set it for DCN20, this commit initializes the set_vtotal_min_max with
the DCN10 function.

[Why]
Dpia hpd interrupt processing is disabled when entering S4/S0i3 and
would be reenabled after detection completes during resuming. Because,
keeping hpd interrupts enabled during detection leads to multiple
detections for the same hpd transition. There is a S4 case where dpia
hpd interrupt is missed when driver is in transitioning from hpd
interrupt processing disable to enable and the display does not light
up.
[How]
- Added dmub inbox command DMUB_CMD__DPIA_HPD_INT_ENABLE to explicitly
control dmub to issue dpia hpd interrupt or not. If dpia hpd interrupt
is disabled, dmub will keep the hpd pending and post it once driver
reenables dpia hpd interrupt or when querying with
DMUB_CMD__QUERY_HPD_STATE.
- Added dmub boot option dpia_hpd_int_enable_supported to notify dmub
about whether DMUB_CMD__DPIA_HPD_INT_ENABLE command would be used.

Before enabling new crtc, stream_count in dc_state does not sync with
that in drm_atomic_state. Validating dsc in such case would leave newly
added stream not jointly participating in dsc optimization with existing
streams, but simply using default initialized vcpi all the time which
gives wrong dsc determination decision.
Consider the scenaio where one 4k60 connected to the dock under dp-alt mode.
Since dp-alt mode is 2-lane setup, stream 1 consumes 63 slots with dsc needed.
Then hook up a second 4k60 to the dock.
stream 2 connected with 65 slot initialized by default without dsc. dsc
pre validate will not jointly optimize stream 2 with stream 1 before
crtc 2 added into the dc_state. That leads to stream 2 not getting dsc
optimization, and trigger atomic_check failure all the time, as 65 > 63
limit.
After getting all new crtcs added into the state, stream_count in
dc_state correctly reflect that in drm_atomic_state which comes up with
correct dsc decision.

Pull random number generator updates from Jason Donenfeld:
- Huawei reported that when they updated their kernel from 4.4 to
something much newer, some userspace code they had broke, the culprit
being the accidental removal of O_NONBLOCK from /dev/random way back
in 5.6. It's been gone for over 2 years now and this is the first
we've heard of it, but userspace breakage is userspace breakage, so
O_NONBLOCK is now back.
- Use randomness from hardware RNGs much more often during early boot,
at the same interval that crng reseeds are done, from Dominik.
- A semantic change in hardware RNG throttling, so that the hwrng
framework can properly feed random.c with randomness from hardware
RNGs that aren't specifically marked as creditable.
A related patch coming to you via Herbert's hwrng tree depends on
this one, not to compile, but just to function properly, so you may
want to merge this PULL before that one.
- A fix to clamp credited bits from the interrupts pool to the size of
the pool sample. This is mainly just a theoretical fix, as it'd be
pretty hard to exceed it in practice.
- Oracle reported that InfiniBand TCP latency regressed by around
10-15% after a change a few cycles ago made at the request of the RT
folks, in which we hoisted a somewhat rare operation (1 in 1024
times) out of the hard IRQ handler and into a workqueue, a pretty
common and boring pattern.
It turns out, though, that scheduling a worker from there has
overhead of its own, whereas scheduling a timer on that same CPU for
the next jiffy amortizes better and doesn't incur the same overhead.
I also eliminated a cache miss by moving the work_struct (and
subsequently, the timer_list) to below a critical cache line, so that
the more critical members that are accessed on every hard IRQ aren't
split between two cache lines.
- The boot-time initialization of the RNG has been split into two
approximate phases: what we can accomplish before timekeeping is
possible and what we can accomplish after.
This winds up being useful so that we can use RDRAND to seed the RNG
before CONFIG_SLAB_FREELIST_RANDOM=y systems initialize slabs, in
addition to other early uses of randomness. The effect is that
systems with RDRAND (or a bootloader seed) will never see any
warnings at all when setting CONFIG_WARN_ALL_UNSEEDED_RANDOM=y. And
kfence benefits from getting a better seed of its own.
- Small systems without much entropy sometimes wind up putting some
truncated serial number read from flash into hostname, so contribute
utsname changes to the RNG, without crediting.
- Add smaller batches to serve requests for smaller integers, and make
use of them when people ask for random numbers bounded by a given
compile-time constant. This has positive effects all over the tree,
most notably in networking and kfence.
- The original jitter algorithm intended (I believe) to schedule the
timer for the next jiffy, not the next-next jiffy, yet it used
mod_timer(jiffies + 1), which will fire on the next-next jiffy,
instead of what I believe was intended, mod_timer(jiffies), which
will fire on the next jiffy. So fix that.
- Fix a comment typo, from William.

When a traditional channel-attached device transitions from not-ready to
ready state, an unsolicited DEVICE END I/O interrupt is raised. This
happens for example when a new file arrives in the z/VM virtual reader
device.
Change the Linux kernel to generate a change uevent when such an
interrupt occurs for any online unit record devices supported by the
vmur driver. This can be useful to automatically trigger processing of
files as they arrive in the reader device.
A sample udev rule for running a program when this event occurs looks as
follows:
ENV{DRIVER}=="vmur", ACTION=="change", ENV{EVENT}=="unsol_de", \
RUN{program}="/path/to/program"
The rule can be tested using the following steps:
1. Set reader device online (assuming default reader device number 000c)
$ chzdev -ea 0.0.000c
2. Force a ready-state transition using z/VM's READY CP command
$ vmcp ready 000c

An existing BUG statement in vmur's interrupt handler triggers if:
1. An online vmur device is removed (e.g. due to driver unload, manual
unbind or channel-report words indicating hypervisor-side device
removal)
2. Device deactivation fails due to firmware/hypervisor error, leaving
subchannel enabled for interrupts + drvdata=NULL
3. Interrupt occurs
This situation is highly unlikely and not a clear indication of a
general system error that would warrant stopping the full Linux system.
Also it can be prevented completely by clearing the interrupt handler
when unsetting a vmur device's drvdata.
Replace the BUG statement in vmur's interrupt handler by clearing the
interrupt handler callback during device removal. Also move the initial
setting of the interrupt handler callback under lock for consistency
reasons.

Patch which added graceful exit for non-persistent contexts missed the
fact it is not enough to set the exiting flag on a context and let the
backend handle it from there.
GuC backend cannot handle it because it runs independently in the
firmware and driver might not see the requests ever again. Patch also
missed the fact some usages of intel_context_is_banned in the GuC backend
needed replacing with newly introduced intel_context_is_schedulable.
Fix the first issue by calling into backend revoke when we know this is
the last chance to do it. Fix the second issue by replacing
intel_context_is_banned with intel_context_is_schedulable, which should
always be safe since latter is a superset of the former.
