Messages around firmware download were incorrectly tagged as being related
to discovery trace events. Thus, firmware download status ended up dumping
the trace log as well as the firmware update message. As there were a
couple of log messages in this state, the trace log was dumped multiple
times.
Resolve this by converting from trace events to SLI events.

The driver is initiating NVMe PRLIs to determine device NVMe support. This
should not be occurring if CONFIG_NVME_FC support is disabled.
Correct this by changing the default value for FC4 support. Currently it
defaults to FCP and NVMe. With change, when NVME_FC support is not enabled
in the kernel, the default value is just FCP.

-Wunaligned-access is a new warning in clang that is default enabled for
arm and arm64 under certain circumstances within the clang frontend (see
LLVM commit below). On v5.17-rc2, an ARCH=arm allmodconfig build shows
1284 total/70 unique instances of this warning (most of the instances
are in header files), which is quite noisy.
To keep a normal build green through CONFIG_WERROR, only show this
warning with W=1, which will allow automated build systems to catch new
instances of the warning so that the total number can be driven down to
zero eventually since catching unaligned accesses at compile time would
be generally useful.

The 'shell' built-in only returns the first 256 bytes of the command's
output. In some cases, 'shell' is used to return a path; by bumping up
the buffer size to 4096 this lets us capture up to PATH_MAX.
The specific case where I ran into this was due to commit 1e860048c5
("gcc-plugins: simplify GCC plugin-dev capability test"). After this
change, we now use `$(shell,$(CC) -print-file-name=plugin)` to return
a path; if the gcc path is particularly long, then the path ends up
truncated at the 256 byte mark, which makes the HAVE_GCC_PLUGINS
depends test always fail.

It is mandatory for a software to issue a reset upon modifying RGMII
Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
Specific Control register 2 (page 2, register 21) otherwise the changes
won't be perceived by the PHY (the same is applicable for a lot of other
registers). Not setting the RGMII delays on the platforms that imply it'
being done on the PHY side will consequently cause the traffic loss. We
discovered that the denoted soft-reset is missing in the
m88e1121_config_aneg() method for the case if the RGMII delays are
modified but the MDIx polarity isn't changed or the auto-negotiation is
left enabled, thus causing the traffic loss on our platform with Marvell
Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the
delays have been actually set in the m88e1121_config_aneg_rgmii_delays()
method.

After commit e3728b50cd ("ACPI: PM: s2idle: Avoid possible race
related to the EC GPE") wakeup interrupts occurring immediately after
the one discarded by acpi_s2idle_wake() may be missed. Moreover, if
the SCI triggers again immediately after the rearming in
acpi_s2idle_wake(), that wakeup may be missed too.
The problem is that pm_system_irq_wakeup() only calls pm_system_wakeup()
when pm_wakeup_irq is 0, but that's not the case any more after the
interrupt causing acpi_s2idle_wake() to run until pm_wakeup_irq is
cleared by the pm_wakeup_clear() call in s2idle_loop(). However,
there may be wakeup interrupts occurring in that time frame and if
that happens, they will be missed.
To address that issue first move the clearing of pm_wakeup_irq to
the point at which it is known that the interrupt causing
acpi_s2idle_wake() to tun will be discarded, before rearming the SCI
for wakeup. Moreover, because that only reduces the size of the
time window in which the issue may manifest itself, allow
pm_system_irq_wakeup() to register two second wakeup interrupts in
a row and, when discarding the first one, replace it with the second
one. [Of course, this assumes that only one wakeup interrupt can be
discarded in one go, but currently that is the case and I am not
aware of any plans to change that.]

Commit 4a9af6cac0 ("ACPI: EC: Rework flushing of EC work while
suspended to idle") made acpi_ec_dispatch_gpe() check
pm_wakeup_pending(), but that is before canceling the SCI wakeup,
so pm_wakeup_pending() is always true. This causes the loop in
acpi_ec_dispatch_gpe() to always terminate after one iteration which
may not be correct.
Address this issue by canceling the SCI wakeup earlier, from
acpi_ec_dispatch_gpe() itself.

Testing on various upcoming OEM systems shows commit 7b167c4cb4 ("ACPI:
PM: Only mark EC GPE for wakeup on Intel systems") was short
sighted and the symptoms were indicative of other problems. Some OEMs
do have the dedicated GPIOs for the power button but also rely upon
an interrupt to the EC SCI to let the lid work.
The original commit showed spurious activity on Lenovo systems:
* On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and
sometimes the power button event doesn't work.
This was confirmed on my end at that time.
However further development in the kernel showed that the issue was
actually the IRQ for the GPIO controller was also shared with the EC SCI.
This was actually fixed by commit 2d54067fcd ("pinctrl: amd: Fix
wakeups when IRQ is shared with SCI").
The original commit also showed problems with AC adapter:
* On HP 635 G7 detaching or attaching AC during suspend will cause
the system not to wakeup
* On Asus vivobook to prevent detaching AC causing resume problems
* On Lenovo 14ARE05 to prevent detaching AC causing resume problems
* On HP ENVY x360 to prevent detaching AC causing resume problems
Detaching AC adapter causing problems appears to have been a problem
because the EC SCI went off to notify the OS of the power adapter change
but the SCI was ignored and there was no other way to wake up this system
since GPIO controller wasn't properly enabled. The wakeups were fixed by
enabling the GPIO controller in commit acd47b9f28 ("pinctrl: amd: Handle
wake-up interrupt").
I've confirmed on a variety of OEM notebooks with the following test
1) echo 1 | sudo tee /sys/power/pm_debug_messages
2) sudo systemctl suspend
3) unplug AC adapter, make sure system is still asleep
4) wake system from lid (which is provided by ACPI SCI on some of them)
5) dmesg
a) see the EC GPE dispatched, timekeeping for X seconds (matching ~time
until AC adapter plug out)
b) see timekeeping for Y seconds until woke (matching ~time from AC
adapter until lid event)
6) Look at /sys/kernel/debug/amd_pmc/s0ix_stats
"Time (in us) in S0i3" = X + Y - firmware processing time

In io_recv(), if import_single_range() fails, the @flags variable is
uninitialized, then it will goto out_free.
After the goto, the compiler doesn't know that (ret < min_ret) is
always true, so it thinks the "if ((flags & MSG_WAITALL) ..." path
could be taken.
The complaint comes from gcc-9 (Debian 9.3.0-22) 9.3.0:
```
fs/io_uring.c:5238 io_recvfrom() error: uninitialized symbol 'flags'
```
Fix this by bypassing the @ret and @flags check when
import_single_range() fails.
Reasons:
1. import_single_range() only returns -EFAULT when it fails.
2. At that point, @flags is uninitialized and shouldn't be read.

The concurrent positioning ranges log page 47h is a general purpose log
page and not a subpage of the indentify device log. Using
ata_identify_page_supported() to test for concurrent positioning ranges
support is thus wrong. ata_log_supported() must be used.
Furthermore, unlike other advanced ATA features (e.g. NCQ priority),
accesses to the concurrent positioning ranges log page are not gated by
a feature bit from the device IDENTIFY data. Since many older drives
react badly to the READ LOG EXT and/or READ LOG DMA EXT commands isued
to read device log pages, avoid problems with older drives by limiting
the concurrent positioning ranges support detection to drives
implementing at least the ACS-4 ATA standard (major version 11). This
additional condition effectively turns ata_dev_config_cpr() into a nop
for older drives, avoiding problems in the field.

On TGL/RKL the BIOS likes to use some kind of bogus DBUF layout
that doesn't match what the spec recommends. With a single active
pipe that is not going to be a problem, but with multiple pipes
active skl_commit_modeset_enables() goes into an infinite loop
since it can't figure out any order in which it can commit the
pipes without causing DBUF overlaps between the planes.
We'd need some kind of extra DBUF defrag stage in between to
make the transition possible. But that is clearly way too complex
a solution, so in the name of simplicity let's just sanitize the
DBUF state by simply turning off all planes when we detect a
pipe encroaching on its neighbours' DBUF slices. We only have
to disable the primary planes as all other planes should have
already been disabled (if they somehow were enabled) by
earlier sanitization steps.
And for good measure let's also sanitize in case the DBUF
allocations of the pipes already seem to overlap each other.

During readout we cannot assume the planes are actually using the
slices they are supposed to use. The BIOS may have misprogrammed
things and put the planes onto the wrong dbuf slices. So let's
do the readout more carefully to make sure we really know which

The i915_ttm_accel_move() function may return error codes that should
be propagated further up the stack rather than consumed assuming that
the accel move failed and could be replaced with a memcpy move.
For -EINTR, -ERESTARTSYS and -EAGAIN, just propagate those codes, rather
than retrying with a memcpy move.

Currently we allow DRRS on IVB PCH ports, but we're missing a
few programming steps meaning it is guaranteed to not work.
And on HSW DRRS is not supported on anything but port A ever
as only transcoder EDP has the M2/N2 registers (though I'm
not sure if HSW ever has eDP on any other port).
Starting from BDW all transcoders have the dynamically
reprogrammable M/N registers so DRRS could work on any
port.
Stop initializing DRRS on ports where it cannot possibly work.

Syzbot found a GPF in reweight_entity. This has been bisected to
commit 4ef0c5c6b5 ("kernel/sched: Fix sched_fork() access an invalid
sched_task_group")
There is a race between sched_post_fork() and setpriority(PRIO_PGRP)
within a thread group that causes a null-ptr-deref in
reweight_entity() in CFS. The scenario is that the main process spawns
number of new threads, which then call setpriority(PRIO_PGRP, 0, -20),
wait, and exit. For each of the new threads the copy_process() gets
invoked, which adds the new task_struct and calls sched_post_fork()
for it.
In the above scenario there is a possibility that
setpriority(PRIO_PGRP) and set_one_prio() will be called for a thread
in the group that is just being created by copy_process(), and for
which the sched_post_fork() has not been executed yet. This will
trigger a null pointer dereference in reweight_entity(), as it will
try to access the run queue pointer, which hasn't been set.
Before the mentioned change the cfs_rq pointer for the task has been
set in sched_fork(), which is called much earlier in copy_process(),
before the new task is added to the thread_group. Now it is done in
the sched_post_fork(), which is called after that. To fix the issue
the remove the update_load param from the update_load param() function
and call reweight_task() only if the task flag doesn't have the
TASK_NEW flag set.
