dcn301_calculate_wm_and_dl() causes flickering when external monitor is
connected.
This issue has been fixed before by commit 0e4c0ae59d
("drm/amdgpu/display: drop dcn301_calculate_wm_and_dl for now"), however
part of the fix was gone after commit 2cbcb78c9e ("Merge tag 'amd-drm-next-5.13-2021-03-23' of https://gitlab.freedesktop.org/agd5f/linux into drm-next").

The TA has a limit to the amount of data that can be retrieved from
GET_TOPOLOGY. For setups that exceed this limit, the xGMI topology
needs to be re-initialized and data needs to be re-fetched from the
extended link records by setting a flag in the shared command buffer.
The number of hops and the number of links must be accumulated by the
driver. Other data points are all fetched from the first request.
Because the TA has already exceeded its link record limit, it
cannot hold bidirectional information. Otherwise the driver would
have to do more than two fetches so the driver has to reflect the
topology information in the opposite direction.

Previously, the ACPI_COMPANION() of a pci_dev was usually set by
acpi_bind_one() in this path:
pci_device_add
pci_configure_device
pci_init_capabilities
device_add
device_platform_notify
acpi_platform_notify
acpi_device_notify # KOBJ_ADD
acpi_bind_one
ACPI_COMPANION_SET
However, things like pci_configure_device() and pci_init_capabilities()
that run before device_add() need the ACPI_COMPANION, e.g.,
acpi_pci_bridge_d3() uses a _DSD method to learn about D3 support. These
places had special-case code to manually look up the ACPI_COMPANION.
Set the ACPI_COMPANION earlier, in pci_setup_device(), so it will be
available while configuring the device. This covers both paths to creating
pci_dev objects:
pci_scan_single_device # for normal non-SR-IOV devices
pci_scan_device
pci_setup_device
pci_set_acpi_fwnode
pci_device_add
pci_iov_add_virtfn # for SR-IOV virtual functions
pci_setup_device
pci_set_acpi_fwnode
Also move the OF fwnode setup to the same spot.

Kprobe and uprobe events can add a "system" to the events that are created
via the kprobe_events and uprobe_events files respectively. If they do not
include a "system" in the name, then the default "kprobes" or "uprobes" is
used. The current notation to specify a system for one of these probe
events is to add a '/' delimiter in the name, where the content before the
'/' will be the system to use, and the content after will be the event
name.
echo 'p:my_system/my_event' > kprobe_events
But this is inconsistent with the way histogram triggers separate their
system / event names. The histogram triggers use a '.' delimiter, which
can be confusing.
To allow this to be more consistent, as well as keep backward
compatibility, allow the kprobe and uprobe events to denote a system name
with either a '/' or a '.'.
That is:
echo 'p:my_system/my_event' > kprobe_events
is equivalent to:
echo 'p:my_system.my_event' > kprobe_events

The two places that call traceprobe_parse_probe_arg() allocate a temporary
buffer to copy the argv[i] into, because argv[i] is constant and the
traceprobe_parse_probe_arg() will modify it to do the parsing. These two
places allocate this buffer and then free it right after calling this
function, leaving the onus of this allocation to the caller.
As there's about to be a third user of this function that will have to do
the same thing, instead of having the caller allocate the temporary
buffer, simply move that allocation into the traceprobe_parse_probe_arg()
itself, which will simplify the code of the callers.

As dynamic events are not created by modules, if something is attached to
one, calling "try_module_get()" on its "mod" field, is not going to keep
the dynamic event from going away.
Since dynamic events do not need the "mod" pointer of the event structure,
make a union out of it in order to save memory (there's one structure for
each of the thousand+ events in the kernel), and have any event with the
DYNAMIC flag set to use a ref counter instead.

To differentiate between static and dynamic events, add a new flag
DYNAMIC to the event flags that all dynamic events have set. This will
allow to differentiate when attaching to a dynamic event from a static
event.
Static events have a mod pointer that references the module they were
created in (or NULL for core kernel). This can be incremented when the
event has something attached to it. But there exists no such mechanism for
dynamic events. This is dangerous as the dynamic events may now disappear
without the "attachment" knowing that it no longer exists.
To enforce the dynamic flag, change dyn_event_add() to pass the event that
is being created such that it can set the DYNAMIC flag of the event. This
helps make sure that no location that creates a dynamic event misses
setting this flag.

Overlayfs does not cache ACL's (to avoid double caching). Instead it just
calls the underlying filesystem's i_op->get_acl(), which will return the
cached value, if possible.
In rcu path walk, however, get_cached_acl_rcu() is employed to get the
value from the cache, which will fail on overlayfs resulting in dropping
out of rcu walk mode. This can result in a big performance hit in certain
situations.

When the max pages (last_page in the swap header + 1) is smaller than
the total pages (inode size) of the swapfile, iomap_swapfile_activate
overwrites sis->max with total pages.
However, frontswap_map is a swap page state bitmap allocated using the
initial sis->max page count read from the swap header. If swapfile
activation increases sis->max, it's possible for the frontswap code to
walk off the end of the bitmap, thereby corrupting kernel memory.
[djwong: modify the description a bit; the original paragraph reads:
"However, frontswap_map is allocated using max pages. When test and clear
the sis offset, which is larger than max pages, of frontswap_map in
__frontswap_invalidate_page(), neighbors of frontswap_map may be
overwritten, i.e., slab is polluted."
Note also that this bug resulted in a behavioral change: activating a
swap file that was formatted and later extended results in all pages
being activated, not the number of pages recorded in the swap header.]
This fixes the issue by considering the limitation of max pages of swap
info in iomap_swapfile_add_extent().
To reproduce the case, compile kernel with slub RED ZONE, then run test:
$ sudo stress-ng -a 1 -x softlockup,resources -t 72h --metrics --times \
--verify -v -Y /root/tmpdir/stress-ng/stress-statistic-12.yaml \
--log-file /root/tmpdir/stress-ng/stress-logfile-12.txt \

The 'contains' keyword applies to elements within an array, so
using 'items' only makes sense if the elements of the array are another
array which is not the case for 'compatible' properties.
Looking at the driver, it seems the intent was the condition should be
true when 'faraday,ftpci100' is present, so we can drop
'cortina,gemini-pci'.
Fixes: 2720b99133 ("dt-bindings: PCI: ftpci100: convert faraday,ftpci100 to YAML")
