There is no need to call dev_kfree_skb() when usb_submit_urb() fails
because can_put_echo_skb() deletes original skb and
can_free_echo_skb() deletes the cloned skb.

can_put_echo_skb() will clone skb then free the skb. Move the
can_put_echo_skb() for the m_can version 3.0.x directly before the

The previous commit fixed a memory leak on the send path in the event
that IPv6 is disabled at compile time, but how did a packet even arrive
there to begin with? It turns out we have previously allowed IPv6
endpoints even when IPv6 support is disabled at compile time. This is
awkward and inconsistent. Instead, let's just ignore all things IPv6,
the same way we do other malformed endpoints, in the case where IPv6 is
disabled.

We make too nuanced use of ptr_ring to entirely move to the skb_array
wrappers, but we at least should avoid the naughty function pointer cast
when cleaning up skbs. Otherwise RAP/CFI will honk at us. This patch
uses the __skb_array_destroy_skb wrapper for the cleanup, rather than
directly providing kfree_skb, which is what other drivers in the same
situation do too.

Scenario:
---------
bio chain generated by blk_queue_split().
Some split bio fails and propagates its error status to the "parent" bio.
But then the (last part of the) parent bio itself completes without error.
We would clobber the already recorded error status with BLK_STS_OK,
causing silent data corruption.
Reproducer:
-----------
How to trigger this in the real world within seconds:
DRBD on top of degraded parity raid,
small stripe_cache_size, large read_ahead setting.
Drop page cache (sysctl vm.drop_caches=1, fadvise "DONTNEED",
umount and mount again, "reboot").
Cause significant read ahead.
Large read ahead request is split by blk_queue_split().
Parts of the read ahead that are already in the stripe cache,
or find an available stripe cache to use, can be serviced.
Parts of the read ahead that would need "too much work",
would need to wait for a "stripe_head" to become available,
are rejected immediately.
For larger read ahead requests that are split in many pieces, it is very
likely that some "splits" will be serviced, but then the stripe cache is
exhausted/busy, and the remaining ones will be rejected.

rpmsg devices to acquire pointers to memory shared with the remote
processor.
The TI K3 R5F and DSP drivers gains support for attaching to instances

The Mediatek remoteproc driver gains support for the MT8186 SCP. The
driver's probe function is reordered and moved to use the devres
version of rproc_alloc() to save a few gotos. The driver's probe
function is also transitioned to use dev_err_probe() to provide better
debug support.

voting for interconnect bandwidth during launch of the remote
processor. The modem subsystem (MSS) driver gains support for probing
the BAM-DMUX driver, which provides the network interface towards the

git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux
Pull clk updates from Stephen Boyd:
"There's one large change in the core clk framework here. We change how
clk_set_rate_range() works so that the frequency is re-evaulated each
time the rate is changed. Previously we wouldn't let clk providers see
a rate that was different if it was still within the range, which
could be bad for power if the clk could run slower when a range
expands. Now the clk provider can decide to do something differently
when the constraints change. This broke Nvidia's clk driver so we had
to wait for the fix for that to bake a little more in -next.
The rate range patch series also introduced a kunit suite for the clk
framework that we're going to extend in the next release. It already
made it easy to find corner cases in the rate range patches so I'm
excited to see it cover more clk code and increase our confidence in
core framework patches in the future. I also added a kunit test for
the basic clk gate code and that work will continue to cover more
basic clk types: muxes, dividers, etc.
Beyond the core code we have the usual set of clk driver updates and
additions. Qualcomm again dominates the diffstat here with lots more
SoCs being supported and i.MX follows afer that with a similar number
of SoCs gaining clk drivers. Beyond those large additions there's
drivers being modernized to use clk_parent_data so we can move away
from global string names for all the clks in an SoC. Finally there's
lots of little fixes all over the clk drivers for typos, warnings, and
missing clks that aren't critical and get batched up waiting for the
next merge window to open. Nothing super big stands out in the driver
pile. Full details are below.
Core:
- Make clk_set_rate_range() re-evaluate the limits each time
- Introduce various clk_set_rate_range() tests

Pull libnvdimm updates from Dan Williams:
"The update for this cycle includes the deprecation of block-aperture
mode and a new perf events interface for the papr_scm nvdimm driver.
The perf events approach was acked by PeterZ.
- Add perf support for nvdimm events, initially only for 'papr_scm'
devices.
- Deprecate the 'block aperture' support in libnvdimm, it only ever
existed in the specification, not in shipping product"

Support for cryptoloop was deleted in commit 47e9624616c8 ("block:
remove support for cryptoloop and the xor transfer"), making the usage
of loop_info->lo_encrypt_type obsolete. However, this member was also
removed from the compat_loop_info definition and this breaks userspace
ioctl calls for 32-bit binaries and CONFIG_COMPAT=y.
This patch restores the compat_loop_info->lo_encrypt_type member and
marks it obsolete as well as in the uapi header definitions.

Setting the century forward has been failing on AMD platforms.
There was a previous attempt at fixing this for family 0x17 as part of
commit 7ad295d5196a ("rtc: Fix the AltCentury value on AMD/Hygon
platform") but this was later reverted due to some problems reported
that appeared to stem from an FW bug on a family 0x17 desktop system.
The same comments mentioned in the previous commit continue to apply
to the newer platforms as well.
```
MC146818 driver use function mc146818_set_time() to set register
RTC_FREQ_SELECT(RTC_REG_A)'s bit4-bit6 field which means divider stage
reset value on Intel platform to 0x7.
While AMD/Hygon RTC_REG_A(0Ah)'s bit4 is defined as DV0 [Reference]:
DV0 = 0 selects Bank 0, DV0 = 1 selects Bank 1. Bit5-bit6 is defined
as reserved.
DV0 is set to 1, it will select Bank 1, which will disable AltCentury
register(0x32) access. As UEFI pass acpi_gbl_FADT.century 0x32
(AltCentury), the CMOS write will be failed on code:
CMOS_WRITE(century, acpi_gbl_FADT.century).
Correct RTC_REG_A bank select bit(DV0) to 0 on AMD/Hygon CPUs, it will
enable AltCentury(0x32) register writing and finally setup century as
expected.
```
However in closer examination the change previously submitted was also
modifying bits 5 & 6 which are declared reserved in the AMD documentation.
So instead modify just the DV0 bank selection bit.
Being cognizant that there was a failure reported before, split the code
change out to a static function that can also be used for exclusions if
any regressions such as Mikhail's pop up again.

Freescale Layerscape Lynx 28G SerDes PHYs are only present on
Freescale/NXP Layerscape SoCs.
Move PHY_FSL_LYNX_28G outside the block for ARCH_MXC, as the latter
is meant for i.MX8 SoCs, which is a different family than Layerscape.
Add a dependency on ARCH_LAYERSCAPE, to prevent asking the user about
this driver when configuring a kernel without Layerscape SoC support.

ioctls handled by phy_mii_ioctl() will cause a kernel oops when the
interface is down. Fix it by making sure there is a PHY attached.

nvme_mpath_init_identify() invoked from nvme_init_identify() fetches a
fresh ANA log from the ctrl. This is essential to have an up to date
path states for both existing namespaces and for those scan_work may
discover once the ctrl is up.
This happens in the following cases:
1) A new ctrl is being connected.
2) An existing ctrl is successfully reconnected.
3) An existing ctrl is being reset.
While in (1) ctrl->namespaces is empty, (2 & 3) may have namespaces, and
nvme_read_ana_log() may call nvme_update_ns_ana_state().
This result in a hang when the ANA state of an existing namespace changes
and makes the disk live: nvme_mpath_set_live() issues IO to the namespace
through the ctrl, which does NOT have IO queues yet.
See sample hang below.
Solution:
- nvme_update_ns_ana_state() to call set_live only if ctrl is live
- nvme_read_ana_log() call from nvme_mpath_init_identify()
therefore only fetches and parses the ANA log;
any erros in this process will fail the ctrl setup as appropriate;
- a separate function nvme_mpath_update()
is called in nvme_start_ctrl();
this parses the ANA log without fetching it.
At this point the ctrl is live,
therefore, disks can be set live normally.
Sample failure:
nvme nvme0: starting error recovery
nvme nvme0: Reconnecting in 10 seconds...
block nvme0n6: no usable path - requeuing I/O
INFO: task kworker/u8:3:312 blocked for more than 122 seconds.

Make nvme_ns_remove match the assumptions elsewhere.
1) !NVME_NS_READY needs to be srcu synchronized to make sure nothing is
running in __nvme_find_path or nvme_round_robin_path that will
re-assign this ns to current_path.
2) Any matching current_path entries need to be cleared before removing
from the siblings list, to prevent calling nvme_round_robin_path with
an "old" ns that's off list.
3) Finally the list_del_rcu can happen, and then synchronize again
before releasing any reference counts.

A NVMe subsystem with multiple controller can have private namespaces
that use the same NSID under some conditions:
"If Namespace Management, ANA Reporting, or NVM Sets are supported, the
NSIDs shall be unique within the NVM subsystem. If the Namespace
Management, ANA Reporting, and NVM Sets are not supported, then NSIDs:
a) for shared namespace shall be unique; and
b) for private namespace are not required to be unique."
Reference: Section 6.1.6 NSID and Namespace Usage; NVM Express 1.4c spec.
Make sure this specific setup is supported in Linux.

The left shift is followed by a re-assignment back to cc_css, the
assignment is redundant. Fix this by replacing the "<<=" operator with
"<<" instead.
This cleans up the clang scan build warning:

Any attempt to flush kernel-global WQs has possibility of deadlock
so we should simply stop using them, instead introduce nvmet_wq
which is the generic nvmet workqueue for work elements that
don't explicitly require a dedicated workqueue (by the mere fact
that they are using the system_wq).
Changes were done using the following replaces:
- s/schedule_work(/queue_work(nvmet_wq, /g
- s/schedule_delayed_work(/queue_delayed_work(nvmet_wq, /g
- s/flush_scheduled_work()/flush_workqueue(nvmet_wq)/g
