Query a dynamically-allocated counter before release it, to update it's
hwcounters and log all of them into history data. Otherwise all values of
these hwcounters will be lost.

Virtio-mem managed memory is always detected and added by the virtio-mem
driver, never using something like the firmware-provided memory map.
This is the case after an ordinary system reboot, and has to be guaranteed
after kexec. Especially, virtio-mem added memory resources can contain
inaccessible parts ("unblocked memory blocks"), blindly forwarding them
to a kexec kernel is dangerous, as unplugged memory will get accessed
(esp. written).
Let's use the new way of adding special driver-managed memory introduced
in commit 7b7b27214bba ("mm/memory_hotplug: introduce
add_memory_driver_managed()").
This will result in no entries in /sys/firmware/memmap ("raw firmware-
provided memory map"), the memory resource will be flagged
IORESOURCE_MEM_DRIVER_MANAGED (esp., kexec_file_load() will not place
kexec images on this memory), and it is exposed as "System RAM
(virtio_mem)" in /proc/iomem, so esp. kexec-tools can properly handle it.
Example /proc/iomem before this change:
[...]
140000000-333ffffff : virtio0
140000000-147ffffff : System RAM
334000000-533ffffff : virtio1
338000000-33fffffff : System RAM
340000000-347ffffff : System RAM
348000000-34fffffff : System RAM
[...]
Example /proc/iomem after this change:
[...]
140000000-333ffffff : virtio0
140000000-147ffffff : System RAM (virtio_mem)
334000000-533ffffff : virtio1
338000000-33fffffff : System RAM (virtio_mem)
340000000-347ffffff : System RAM (virtio_mem)
348000000-34fffffff : System RAM (virtio_mem)

Smatch complains that "rc" can be uninitialized if we hit the "break;"

When /sys/firmware/acpi/pm_profile is read, sysfs_kf_seq_show is called,
which in turn calls kobj_attr_show, which gets the ->show callback
member by calling container_of on attr (casting it to struct
kobj_attribute) then calls it.
There is a CFI violation because pm_profile_attr is of type
struct device_attribute but kobj_attr_show calls ->show expecting it
to be from struct kobj_attribute. CFI checking ensures that function
pointer types match when doing indirect calls. Fix pm_profile_attr to
be defined in terms of kobj_attribute so there is no violation or
mismatch.

Like other vectors already patched, this one here allows the root
user to load ACPI tables, which enables arbitrary physical address
writes, which in turn makes it possible to disable lockdown.
Prevents this by checking the lockdown status before allowing a new
ACPI table to be installed. The link in the trailer shows a PoC of
how this might be used.

If shared interrupt comes late, during probe error path or device remove
(could be triggered with CONFIG_DEBUG_SHIRQ), the interrupt handler
dspi_interrupt() will access registers with the clock being disabled.
This leads to external abort on non-linefetch on Toradex Colibri VF50
module (with Vybrid VF5xx):
$ echo 4002d000.spi > /sys/devices/platform/soc/40000000.bus/4002d000.spi/driver/unbind
Unhandled fault: external abort on non-linefetch (0x1008) at 0x8887f02c
Internal error: : 1008 [#1] ARM
Hardware name: Freescale Vybrid VF5xx/VF6xx (Device Tree)

(device_release_driver_internal)
The resource-managed framework should not be used for shared interrupt
handling, because the interrupt handler might be called after releasing
other resources and disabling clocks.
Similar bug could happen during suspend - the shared interrupt handler
could be invoked after suspending the device. Each device sharing this
interrupt line should disable the IRQ during suspend so handler will be
invoked only in following cases:
1. None suspended,
2. All devices resumed.

During shutdown, the driver should unregister the SPI controller
and stop the hardware. Otherwise the dspi_transfer_one_message() could
wait on completion infinitely.
Additionally, calling spi_unregister_controller() first in device

registered at the end.

Even with moving netif_tx_disable() to an earlier point when
taking down the queues for a reconfiguration, we still end
up with the occasional netdev watchdog Tx Timeout complaint.
The old method of using netif_trans_update() works fine for

Use the correct the function name in the documentation for
"pcs_parse_one_pinctrl_entry()".
"smux_parse_one_pinctrl_entry()" appears to be an artifact from the
development of a prior patch series ("simple pinmux driver") which

Pull libnvdimm updates from Dan Williams:
"A feature (papr_scm health retrieval) and a fix (sysfs attribute
visibility) for v5.8.
Vaibhav explains in the merge commit below why missing v5.8 would be
painful and I agreed to try a -rc2 pull because only cosmetics kept
this out of -rc1 and his initial versions were posted in more than
enough time for v5.8 consideration:
'These patches are tied to specific features that were committed to
customers in upcoming distros releases (RHEL and SLES) whose
time-lines are tied to 5.8 kernel release.
Being able to track the health of an nvdimm is critical for our
customers that are running workloads leveraging papr-scm nvdimms.
Missing the 5.8 kernel would mean missing the distro timelines and
shifting forward the availability of this feature in distro kernels
by at least 6 months'
Summary:
- Fix the visibility of the region 'align' attribute.
The new unit tests for region alignment handling caught a corner
case where the alignment cannot be specified if the region is
converted from static to dynamic provisioning at runtime.
- Add support for device health retrieval for the persistent memory
supported by the papr_scm driver.
This includes both the standard sysfs "health flags" that the nfit
persistent memory driver publishes and a mechanism for the ndctl
tool to retrieve a health-command payload"

VLAN tag insertion/extraction offload is correctly
activated at probe time but deactivation of this feature
(i.e. via ethtool) is broken. Toggling works only for
Tx/Rx ring 0 of a PF, and is ignored for the other rings,
including the VF rings.
To fix this, the existing VLAN offload toggling code
was extended to all the rings assigned to a netdevice,
instead of the default ring 0 (likely a leftover from the
early validation days of this feature). And the code was
moved to the common set_features() function to fix toggling
for the VF driver too.

Commit 02a6efcab675 ("net: phy: allow scanning busses with missing
phys") added a special condition to return -ENODEV in case -ENODEV or
-EIO was returned from the first read of the MII_PHYSID1 register.
In case the MDIO bus data line pull-up is not strong enough, the MDIO
bus controller will not flag this as a read error. This can happen when
a pluggable daughter card is not connected and weak internal pull-ups
are used (since that is the only option, otherwise the pins are
floating).
The second read of MII_PHYSID2 will be correctly flagged an error
though, but now we will return -EIO which will be treated as a hard
error, thus preventing MDIO bus scanning loops to continue succesfully.
Apply the same logic to both register reads, thus allowing the scanning
logic to proceed.

Commit 209c65b61d94 ("drivers/of/of_mdio.c:fix of_mdiobus_register()")
introduced a break of the loop on the premise that a successful
registration should exit the loop. The premise is correct but not to
code, because rc && rc != -ENODEV is just a special error condition,
that means we would exit the loop even with rc == -ENODEV which is
absolutely not correct since this is the error code to indicate to the
MDIO bus layer that scanning should continue.
Fix this by explicitly checking for rc = 0 as the only valid condition
to break out of the loop.

When dm zoned has multiple devices, random zones are never selected for
reclaim if all reserved sequential write zones are in use and no
sequential write required zones can be selected for reclaim. This can
lead to deadlocks as selecting a cache zone allows reclaiming a
sequential zone, ensuring forward progress.
Fix this by always defaulting to selecting a random zone when no
sequential write required zone can be selected.

Commit 2094045fe5b5 ("dm zoned: prefer full zones for reclaim")
modified dmz_get_rnd_zone_for_reclaim() to add a search for the buffer
zone with the heaviest weight as an optimal candidate for reclaim. This
modification uses the zone pointer variabl "last" which is set only once
and never modified as zones are scanned, resulting in the search being
inefective. Furthermore, if the selected buffer zone at the end of the
search loop is active or already locked for reclaim,
dmz_get_rnd_zone_for_reclaim() returns NULL even if other random zones
with a lesser weight can be reclaimed.
To fix the search and to guarantee that reclaim can make forward
progress, fix dmz_get_rnd_zone_for_reclaim() loop to correctly find
the buffer zone with the heaviest weight using the variable maxw_z.
Also make sure to fallback to finding the first random zone that can
be reclaimed if this best candidate zone cannot be reclaimed.
While at it, also fix the device index check to consider only random
zones, ignoring cache zones belonging to the cache device if one is
used as that device does not have a reclaim process.
