[Why]
In an effort to stop redundant calls to dce110_disable_audio_stream
the audio->enabled flag was added to the audio resource struct. While
this state probably shouldn't have been tracked on the audio struct
itself it still works fine for some sequences.
However, it does not work for cases where we're freeing the audio
resource (such as hotplugs) or when dynamic audio is enabled.
In these cases the pipe_ctx->stream_res.audio = NULL before we can
set audio->enabled = false. The next time we acquire the audio resource
such as on hotplug the audio will not be enabled for the stream since
DC thinks it's still enabled.
Audio state tracking should cover this sequence.
[How]
Set audio->enabled = false at the start as long as we have
pipe_ctx->stream_res.audio.

This reverts commit 0298d5435276e7795b0b939d74827f6e775e7009.
With this patch, set 'poll_queues > hard queues' will lead to 'nr_read_queues = 0'
in nvme_calc_irq_sets. Then poll_queues setting can fail since dev->tagset.nr_maps
equals to 2 and nvme_pci_map_queues will not do map for poll queues.

Fix a crash with multipath activated. It happends when ANA log
page is larger than MDTS and because of that ANA is disabled.
The driver then tries to access unallocated buffer when connecting
to a nvme target. The signature is as follows:

When freeing the subsystem after finding another match with
__nvme_find_get_subsystem(), use put_device() instead of
__nvme_release_subsystem() which calls kfree() directly.
Per the documentation, put_device() should always be used
after device_initialization() is called. Otherwise, leaks
like the one below which was detected by kmemleak may occur.
Once the call of __nvme_release_subsystem() is removed it no
longer makes sense to keep the helper, so fold it back
into nvme_release_subsystem().

The IQD mcast queue doesn't support QAOB mode, so skip the
qdio_enable_async_operation() setup call for this queue. This avoids
the allocation of an unneeded QAOB pointer array, and sets up q->use_cq
properly so that drivers are prohibited from using QAOBs for mcast
traffic.
Take this opportunity to streamline the q->use_cq and aob != 0 checks.
The path to qdio_siga_output() is straight-forward, we don't need to
worry about being called with bad operands.

If the device driver were to send out a full queue's worth of SBALs,
current code would end up discovering the last of those SBALs as PRIMED
and erroneously skip the SIGA-w. This immediately stalls the queue.
Add a check to not attempt fast-requeue in this case. While at it also
make sure that the state of the previous SBAL was successfully extracted
before inspecting it.

Commit dd5142ca5d24 ("iommu/vt-d: Add debugfs support to show scalable mode
DMAR table internals") prints content of pasid table entries from LSB to
MSB where as other entries are printed MSB to LSB. So, to maintain
uniformity among all entries and to not confuse the user, print MSB first.

Since the cached32_node is allowed to be advanced above dma_32bit_pfn
(to provide a shortcut into the limited range), we need to be careful to
remove the to be freed node if it is the cached32_node.

There is a couple of places where on domain_init() failure domain_exit()
is called. While currently domain_init() can fail only if
alloc_pgtable_page() has failed.
Make domain_exit() check if domain->pgd present, before calling
domain_unmap(), as it theoretically should crash on clearing pte entries
in dma_pte_clear_level().

Intel VT-d driver was reworked to use common deferred flushing
implementation. Previously there was one global per-cpu flush queue,
afterwards - one per domain.
Before deferring a flush, the queue should be allocated and initialized.
Currently only domains with IOMMU_DOMAIN_DMA type initialize their flush
queue. It's probably worth to init it for static or unmanaged domains
too, but it may be arguable - I'm leaving it to iommu folks.
Prevent queuing an iova flush if the domain doesn't have a queue.
The defensive check seems to be worth to keep even if queue would be
initialized for all kinds of domains. And is easy backportable.
On 4.19.43 stable kernel it has a user-visible effect: previously for
devices in si domain there were crashes, on sata devices:

As we have abandoned the home-made lazy domain allocation
and delegated the DMA domain life cycle up to the default
domain mechanism defined in the generic iommu layer, we
needn't consider pci alias anymore when mapping/unmapping
the context entries. Without this fix, we see kernel NULL
pointer dereference during pci device hot-plug test.

The MMIO RAPL interface driver depends on both powercap subsystem and
the intel_rapl_common code.
But when all of them are built-in, the MMIO RAPL interface driver can
be loaded before the other two and this breaks the system during boot.
Fix this by adjusting the init order of the powercap subsystem and the
intel_rapl_common code, so that it can be initialized first.
Fixes: 555c45fe0d04 ("int340X/processor_thermal_device: add support for MMIO RAPL")

The code in occ_get_powr_avg() invokes div64_u64() without checking the

Check the divisor and make it return 0 if the divisor is 0.

vrf_process_v4_outbound() and vrf_process_v6_outbound() do routing
using ip/ipv6 addresses, but don't make sure the header is available
in skb->data[] (skb_headlen() is less then header size).
Case:
1) igb driver from intel.
2) Packet size is greater then 255.
3) MPLS forwards to VRF device.
So, patch adds pskb_may_pull() calls in vrf_process_v4/v6_outbound()
functions.

Commit 8c0d3a02c130 ("PCI: Add accessors for PCI Express Capability")
added accessors for the PCI Express Capability so that drivers didn't
need to be aware of differences between v1 and v2 of the PCI
Express Capability.
Replace pci_read_config_word() and pci_write_config_word() calls with
pcie_capability_read_word() and pcie_capability_write_word().

As pointed out by Firo Yang, a netdev tx timeout may trigger just before an
ethtool set_channels operation is started. be_tx_timeout(), which dumps
some queue structures, is not written to run concurrently with
be_update_queues(), which frees/allocates those queues structures. Add some
synchronization between the two.

This patch fixes an issue seen on Power systems with bnx2x which results
in the skb is NULL WARN_ON in bnx2x_free_tx_pkt firing due to the skb
pointer getting loaded in bnx2x_free_tx_pkt prior to the hw_cons
load in bnx2x_tx_int. Adding a read memory barrier resolves the issue.

The RX power read from the SFP uses units of 0.1uW. This must be
scaled to units of uW for HWMON. This requires a divide by 10, not the
current 100.
With this change in place, sensors(1) and ethtool -m agree:
sff2-isa-0000
Adapter: ISA adapter
in0: +3.23 V
temp1: +33.1 C
power1: 270.00 uW
