Here is a warning report about lack of registered release()
from kobject lib:
Device '(null)' does not have a release() function, it is broken and must be fixed.

When regulator_register() returns fail and directly goto `clean` symbol,
rdev->dev has not registered release() function yet (which is registered
by regulator_class in the following), so rdev needs to be freed manually.
If rdev->dev.of_node is not NULL, which means the of_node has gotten by
regulator_of_get_init_data(), it needs to call of_node_put() to avoid
refcount leak.
Otherwise, only calling put_device() would lead memory leak of rdev
in further:

[ Upstream commit c234ba8042 ]
Jeffrey added Multi-MSI support to the pci-hyperv driver by the 4 patches:
08e61e861a ("PCI: hv: Fix multi-MSI to allow more than one MSI vector")
455880dfe2 ("PCI: hv: Fix hv_arch_irq_unmask() for multi-MSI")
b4b77778ec ("PCI: hv: Reuse existing IRTE allocation in compose_msi_msg()")
a2bad844a6 ("PCI: hv: Fix interrupt mapping for multi-MSI")
It turns out that the third patch (b4b77778ec) causes a performance
regression because all the interrupts now happen on 1 physical CPU (or two
pCPUs, if one pCPU doesn't have enough vectors). When a guest has many PCI
devices, it may suffer from soft lockups if the workload is heavy, e.g.,
see https://lwn.net/ml/linux-kernel/20220804025104.15673-1-decui@microsoft.com/
Commit b4b77778ec itself is good. The real issue is that the hypercall in
hv_irq_unmask() -> hv_arch_irq_unmask() ->
hv_do_hypercall(HVCALL_RETARGET_INTERRUPT...) only changes the target
virtual CPU rather than physical CPU; with b4b77778ec, the pCPU is
determined only once in hv_compose_msi_msg() where only vCPU0 is specified;
consequently the hypervisor only uses 1 target pCPU for all the interrupts.
Note: before b4b77778ec, the pCPU is determined twice, and when the pCPU
is determined the second time, the vCPU in the effective affinity mask is
used (i.e., it isn't always vCPU0), so the hypervisor chooses different
pCPU for each interrupt.
The hypercall will be fixed in future to update the pCPU as well, but
that will take quite a while, so let's restore the old behavior in
hv_compose_msi_msg(), i.e., don't reuse the existing IRTE allocation for
single-MSI and MSI-X; for multi-MSI, we choose the vCPU in a round-robin
manner for each PCI device, so the interrupts of different devices can
happen on different pCPUs, though the interrupts of each device happen on
some single pCPU.
The hypercall fix may not be backported to all old versions of Hyper-V, so
we want to have this guest side change forever (or at least till we're sure
the old affected versions of Hyper-V are no longer supported).

[ Upstream commit b8a5376c32 ]
Current handling of the srb_status is incorrect. Commit 52e1b3b3da
("scsi: storvsc: Correctly handle multiple flags in srb_status")
is based on srb_status being a set of flags, when in fact only the
2 high order bits are flags and the remaining 6 bits are an integer
status. Because the integer values of interest mostly look like flags,
the code actually works when treated that way.
But in the interest of correctness going forward, fix this by treating
the low 6 bits of srb_status as an integer status code. Add handling
for SRB_STATUS_INVALID_REQUEST, which was the original intent of commit
52e1b3b3da. Furthermore, treat the ERROR, ABORTED, and INVALID_REQUEST
srb status codes as essentially equivalent for the cases we care about.
There's no harm in doing so, and it isn't always clear which status code
current or older versions of Hyper-V report for particular conditions.
Treating the srb status codes as equivalent has the additional benefit
of ensuring that capacity change events result in an immediate rescan
so that the new size is known to Linux. Existing code checks SCSI
sense data for capacity change events when the srb status is ABORTED.
But capacity change events are also being observed when Hyper-V reports
the srb status as ERROR. Without the immediate rescan, the new size
isn't known until something else causes a rescan (such as running
fdisk to expand a partition), and in the meantime, tools such as "lsblk"
continue to report the old size.

[ Upstream commit ee68154163 ]
Commit e5d9b714fe ("x86/hyperv: fix root partition faults when writing
to VP assist page MSR") moved 'wrmsrl(HV_X64_MSR_VP_ASSIST_PAGE)' under
'if (*hvp)' condition. This works for root partition as hv_cpu_die()
does memunmap() and sets 'hv_vp_assist_page[cpu]' to NULL but breaks
non-root partitions as hv_cpu_die() doesn't free 'hv_vp_assist_page[cpu]'
for them. This causes VP assist page to remain unset after CPU
offline/online cycle:
$ rdmsr -p 24 0x40000073
10212f001
$ echo 0 > /sys/devices/system/cpu/cpu24/online
$ echo 1 > /sys/devices/system/cpu/cpu24/online
$ rdmsr -p 24 0x40000073
0
Fix the issue by always writing to HV_X64_MSR_VP_ASSIST_PAGE in
hv_cpu_init(). Note, checking 'if (!*hvp)', for root partition is
pointless as hv_cpu_die() always sets 'hv_vp_assist_page[cpu]' to
NULL (and it's also NULL initially).
Note: the fact that 'hv_vp_assist_page[cpu]' is reset to NULL may
present a (potential) issue for KVM. While Hyper-V uses
CPUHP_AP_ONLINE_DYN stage in CPU hotplug, KVM uses CPUHP_AP_KVM_STARTING
which comes earlier in CPU teardown sequence. It is theoretically
possible that Enlightened VMCS is still in use. It is unclear if the
issue is real and if using KVM with Hyper-V root partition is even
possible.
While on it, drop the unneeded smp_processor_id() call from hv_cpu_init().

__soc_pcm_open() should not be obliterating those mask values.
The code in __soc_pcm_hw_params() uses these masks to calculate the
active channels so that only the AIF_IN/AIF_OUT widgets for the
active TDM slots are enabled. The zeroing of the masks in
__soc_pcm_open() disables this functionality so all AIF widgets
were enabled even for channels that are not assigned to a TDM slot.

The commit in the "Fixes" tag tried to avoid a case where policy check
is ignored due to dst caching in next hops.
However, when the traffic is locally consumed, the dst may be cached
in a local TCP or UDP socket as part of early demux. In this case the
"disable_policy" flag is not checked as ip_route_input_noref() was only
called before caching, and thus, packets after the initial packet in a
flow will be dropped if not matching policies.
Fix by checking the "disable_policy" flag also when a valid dst is
already available.

The application has direct access to command status, so there's no need
to log these.
And since every passthrough command now uses the quiet flag, move the
setting to the common initializer.

Add the same change for ARM64 as done in the commit 9440c42941
("x86/syscall: Include asm/ptrace.h in syscall_wrapper header") to
make sure all syscalls see 'struct pt_regs' definition and resulted
BTF for '__arm64_sys_*(struct pt_regs *regs)' functions point to
actual struct.
Without this patch, the BPF verifier refuses to load a tracing prog
which accesses pt_regs.

[ Upstream commit 80ddf5ce1c ]
Nathan Chancellor reported several link errors on s390 with
CONFIG_RELOCATABLE disabled, after binutils commit 906f69cf65da ("IBM
zSystems: Issue error for *DBL relocs on misaligned symbols"). The binutils
commit reveals potential miscompiles that might have happened already
before with linker script defined symbols at odd addresses.
A similar bug was recently fixed in the kernel with commit c9305b6c1f
("s390: fix nospec table alignments").
See https://github.com/ClangBuiltLinux/linux/issues/1747 for an analysis
from Ulich Weigand.
Therefore always build a relocatable kernel to avoid this problem. There is
hardly any use-case for non-relocatable kernels, so this shouldn't be
controversial.

From ZBC-1:
- RC BASIS = 0: The RETURNED LOGICAL BLOCK ADDRESS field indicates the
highest LBA of a contiguous range of zones that are not sequential write
required zones starting with the first zone.
- RC BASIS = 1: The RETURNED LOGICAL BLOCK ADDRESS field indicates the LBA
of the last logical block on the logical unit.
The current scsi_debug READ CAPACITY response does not comply with the
above if there are one or more sequential write required zones. SCSI
initiators need a way to retrieve the largest valid LBA from SCSI
devices. Reporting the largest valid LBA if there are one or more
sequential zones requires to set the RC BASIS field in the READ CAPACITY
response to one. Hence this patch.

[ Upstream commit 62fa3ce05d ]
Fix an issue reported when performing a live migration when multipath is
configured with a short fast fail timeout of 5 seconds and also to have
no_path_retry set to fail. In this scenario, all paths would go into the
devloss state while the ibmvfc driver went through discovery to log back
in. On a loaded system, the discovery might take longer than 5 seconds,
which was resulting in all paths being marked failed, which then resulted
in a read only filesystem.
This patch changes the migration code in ibmvfc to avoid deleting rports at
all in this scenario, so we avoid losing all paths.

[ Upstream commit 8bcd560ae8 ]
This reverts commit c850240b6c.
That commit tried to improve the performance of macsec offload by
taking advantage of some of the NIC's features, but in doing so, broke
macsec offload when the lower device supports both macsec and ipsec
offload, as the ipsec offload feature flags (mainly NETIF_F_HW_ESP)
were copied from the real device. Since the macsec device doesn't
provide xdo_* ops, the XFRM core rejects the registration of the new
macsec device in xfrm_api_check.
Example perf trace when running
ip link add link eni1np1 type macsec port 4 offload mac
ip 737 [003] 795.477676: probe:xfrm_dev_event__REGISTER name="macsec0" features=0x1c000080014869
xfrm_dev_event+0x3a
notifier_call_chain+0x47
register_netdevice+0x846
macsec_newlink+0x25a
ip 737 [003] 795.477687: probe:xfrm_dev_event__return ret=0x8002 (NOTIFY_BAD)
notifier_call_chain+0x47
register_netdevice+0x846
macsec_newlink+0x25a
dev->features includes NETIF_F_HW_ESP (0x04000000000000), so
xfrm_api_check returns NOTIFY_BAD because we don't have
dev->xfrmdev_ops on the macsec device.
We could probably propagate GSO and a few other features from the
lower device, similar to macvlan. This will be done in a future patch.

[ Upstream commit 3a89b6dec9 ]
The 2.7.0 series of QCN9074's firmware requests 5 segments
of memory instead of 3 (as in the 2.5.0 series).
The first segment (11M) is too large to be kalloc'd in one
go on x86 and requires piecemeal 1MB allocations, as was
the case with the prior public firmware (2.5.0, 15M).
Since f6f92968e1, ath11k will break the memory requests,
but only if there were fewer than 3 segments requested by
the firmware. It seems that 5 segments works fine and
allows QCN9074 to boot on x86 with firmware 2.7.0, so
change things accordingly.
