This was a mismerge of a semantic conflict in my merge of the driver
core updates, where commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") changed the devnode function pointer
type. In the meantime, the drm tree I merged earlier had introduced a
new use of that in commit 8bf4889762a8 ("drivers/accel: define kconfig
and register a new major").
And of course this happens when I'm traveling with my laptop, and thus
didn't do a full allmodconfig build between every pull and before
pushing my work out.
So I only noticed later as I was doing my full build.

I do not read a strict requirement on /chosen node in either ePAPR or in
Documentation/devicetree. Help text for CONFIG_CMDLINE and
CONFIG_CMDLINE_EXTEND doesn't make their behavior explicitly dependent on
the presence of /chosen or the presense of /chosen/bootargs.
However the early check for /chosen and bailing out in
early_init_dt_scan_chosen() skips CONFIG_CMDLINE handling which is not
really related to /chosen node or the particular method of passing cmdline
from bootloader.
This leads to counterintuitive combinations (assuming
CONFIG_CMDLINE_EXTEND=y):
a) bootargs="foo", CONFIG_CMDLINE="bar" => cmdline=="foo bar"
b) /chosen missing, CONFIG_CMDLINE="bar" => cmdline==""
c) bootargs="", CONFIG_CMDLINE="bar" => cmdline==" bar"
Move CONFIG_CMDLINE handling outside of early_init_dt_scan_chosen() so that
cases b and c above result in the same cmdline.

domain is present
On architectures such as s390 that do not use irq domains for MSI,
returning 0 as the maximum MSI index is a bit counter-productive,
as it indicates that no MSI can be allocated. Bad idea.
Instead, return the maximum we're willing to support in the MSI
backing store (MSI_XA_DOMAIN_SIZE), and let the arch code do its
usual thing.
Thanks to Matthew Rosato for fixing the fix.

For architectures such as s390 and powerpc that do not use
irq domains for MSIs, dev->msi.domain is always NULL, so
the per-device, per-bus MSI domain is also guaranteed to
be NULL.
So checking one without checking the other is bound to result
in a splat, followed by a memory leak as we don't free the MSI
descriptors.
Add the missing check.

It's caused by the assert_spin_locked() failing in assert_pte_locked().
The assert fails because the PTE was unlocked in text_area_cpu_up_mm(),
and never relocked.
The PTE page shouldn't be freed, the patching_mm is only used for
patching on this CPU, only that single PTE is ever mapped, and it's only
unmapped at CPU offline.
In fact assert_pte_locked() has a special case to ignore init_mm
entirely, and the patching_mm is more-or-less like init_mm, so possibly
the check could be skipped for patching_mm too.
But for now be conservative, and use the proper PTE accessors at
patching time, so that the PTE lock is held while the PTE is used. That
also avoids the warning in assert_pte_locked().
With that it's no longer necessary to save the PTE in
cpu_patching_context for the mm_patch_enabled() case.

Pull driver core updates from Greg KH:
"Here is the set of driver core and kernfs changes for 6.2-rc1.
The "big" change in here is the addition of a new macro,
container_of_const() that will preserve the "const-ness" of a pointer
passed into it.
The "problem" of the current container_of() macro is that if you pass
in a "const *", out of it can comes a non-const pointer unless you
specifically ask for it. For many usages, we want to preserve the
"const" attribute by using the same call. For a specific example, this
series changes the kobj_to_dev() macro to use it, allowing it to be
used no matter what the const value is. This prevents every subsystem
from having to declare 2 different individual macros (i.e.
kobj_const_to_dev() and kobj_to_dev()) and having the compiler enforce
the const value at build time, which having 2 macros would not do
either.
The driver for all of this have been discussions with the Rust kernel
developers as to how to properly mark driver core, and kobject,
objects as being "non-mutable". The changes to the kobject and driver
core in this pull request are the result of that, as there are lots of
paths where kobjects and device pointers are not modified at all, so
marking them as "const" allows the compiler to enforce this.
So, a nice side affect of the Rust development effort has been already
to clean up the driver core code to be more obvious about object
rules.
All of this has been bike-shedded in quite a lot of detail on lkml
with different names and implementations resulting in the tiny version
we have in here, much better than my original proposal. Lots of
subsystem maintainers have acked the changes as well.
Other than this change, included in here are smaller stuff like:
- kernfs fixes and updates to handle lock contention better
- vmlinux.lds.h fixes and updates
- sysfs and debugfs documentation updates
- device property updates
All of these have been in the linux-next tree for quite a while with
no problems"

The size of device tree node secmon (bl31_secmon_reserved) was
incorrect. It should be increased to 2MiB (0x200000).
The origin setting will cause some abnormal behavior due to
trusted-firmware-a and related firmware didn't load correctly.
The incorrect behavior may vary because of different software stacks.
For example, it will cause build error in some Yocto project because
it will check if there was enough memory to load trusted-firmware-a
to the reserved memory.
When mt8195-demo.dts sent to the upstream, at that time the size of
BL31 was small. Because supported functions and modules in BL31 are
basic sets when the board was under early development stage.
Now BL31 includes more firmwares of coprocessors and maturer functions
so the size has grown bigger in real applications. According to the value
reported by customers, we think reserved 2MiB for BL31 might be enough
for maybe the following 2 or 3 years.

The commit mentioned below causes the ovs_flow_tbl_lookup() function
to be called with the masked key. However, it's supposed to be called
with the unmasked key. This due to the fact that the datapath supports
installing wider flows, and OVS relies on this behavior. For example
if ipv4(src=1.1.1.1/192.0.0.0, dst=1.1.1.2/192.0.0.0) exists, a wider
flow (smaller mask) of ipv4(src=192.1.1.1/128.0.0.0,dst=192.1.1.2/
128.0.0.0) is allowed to be added.
However, if we try to add a wildcard rule, the installation fails:
$ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \
ipv4(src=1.1.1.1/192.0.0.0,dst=1.1.1.2/192.0.0.0,frag=no)" 2
$ ovs-appctl dpctl/add-flow system@myDP "in_port(1),eth_type(0x0800), \
ipv4(src=192.1.1.1/0.0.0.0,dst=49.1.1.2/0.0.0.0,frag=no)" 2
ovs-vswitchd: updating flow table (File exists)
The reason is that the key used to determine if the flow is already
present in the system uses the original key ANDed with the mask.
This results in the IP address not being part of the (miniflow) key,
i.e., being substituted with an all-zero value. When doing the actual
lookup, this results in the key wrongfully matching the first flow,
and therefore the flow does not get installed.
This change reverses the commit below, but rather than having the key
on the stack, it's allocated.

If FAULT_INJECTION_STACKTRACE_FILTER is enabled, the depth is default to
32. This means fail_stacktrace() will iter each entry's stacktrace, even
if filter is not configured.
This patch changes to quick return from fail_stacktrace() if stacktrace
filter is not set.

This patchset allow fault injection to run on x86_64 and makes stacktrace
filter work as expected. With this, we can test a device driver module
with fault injection more easily.
This patch (of 4):
FAULT_INJECTION_STACKTRACE_FILTER option was apparently disallowed on
x86_64 because of problems with the stack unwinder:
commit 6d690dcac92a84f98fd774862628ff871b713660
Author: Akinobu Mita <akinobu.mita@gmail.com>
Date: Sat May 12 10:36:53 2007 -0700
fault injection: disable stacktrace filter for x86-64
However, there is no problems whatsoever with this today. Let's allow
it again.

Move Sergey to co-maintainer for zram/zsmalloc since he has helped to
contribute/review those areas actively for eight years, which is quite
helpful. Since Nitin has been inactive for several years, it's time to
move his name into CREDITS.

Currently, %p is used to display kernel pointers in backtrace which result
in a hashed value that is not usable to correlate the address for debug.
Use %pK which will respect the kptr_restrict configuration value and thus
allow to extract meaningful information from the backtrace.
