Split intel generic SoundWire machine driver private data into two
structures. One structure is generic one which can be used by other
platform machine driver and the other one is intel specific one.
Move generic machine driver private data to soc_sdw_utils.h.
Define a void pointer in generic machine driver private data structure
and assign the vendor specific structure in mc_probe() call.

If a client sends out a cap update dropping caps with the prior 'seq'
just before an incoming cap revoke request, then the client may drop
the revoke because it believes it's already released the requested
capabilities.
This causes the MDS to wait indefinitely for the client to respond
to the revoke. It's therefore always a good idea to ack the cap
revoke request with the bumped up 'seq'.
Currently if the cap->issued equals to the newcaps the check_caps()
will do nothing, we should force flush the caps.

The recent changes in IOMMU made the non-contiguous page allocations
as default, hence we can simply use the standard DMA allocation for
the S/G pages as well. In this patch, we simplify the code by trying
the standard DMA allocation at first, instead of
dma_alloc_noncontiguous().
For the case without IOMMU, we still need to manage the S/G pages
manually, so we keep the same fallback routines like before.
The fallback types (SNDRV_DMA_TYPE_DEV_SG_FALLBACK & co) are dropped /
folded into SNDRV_DMA_TYPE_DEV_SG and co now. The allocation via the
standard DMA call overrides the type accordingly, hence we don't have
to have extra fallback types any longer. OTOH, SNDRV_DMA_TYPE_DEV_SG
is no longer an alias but became its own type back again.
Note that this patch requires another prerequisite fix for memmalloc
helper to use the DMA API for WC pages on x86.

The memalloc helper used a house-made code for allocation of WC pages
on x86, since the standard DMA API doesn't cover it well. Meanwhile,
the manually allocated pages won't work together with IOMMU, resulting
in faults, so we should switch to the DMA API in that case, instead.
This patch tries to switch back to DMA API for WC pages on x86, but
with some additional tweaks that are missing.

When a subflow receives and discards duplicate data, the mptcp
stack assumes that the consumed offset inside the current skb is
zero.
With multiple subflows receiving data simultaneously such assertion
does not held true. As a result the subflow-level copied_seq will
be incorrectly increased and later on the same subflow will observe
a bad mapping, leading to subflow reset.
Address the issue taking into account the skb consumed offset in
mptcp_subflow_discard_data().

This patch modifies the skb_unref function to skip the early return
optimization when CONFIG_DEBUG_NET is enabled. The change ensures that
the reference count decrement always occurs in debug builds, allowing
for more thorough checking of SKB reference counting.
Previously, when the SKB's reference count was 1 and CONFIG_DEBUG_NET
was not set, the function would return early after a memory barrier
(smp_rmb()) without decrementing the reference count. This optimization
assumes it's safe to proceed with freeing the SKB without the overhead
of an atomic decrement from 1 to 0.
With this change:
- In non-debug builds (CONFIG_DEBUG_NET not set), behavior remains
unchanged, preserving the performance optimization.
- In debug builds (CONFIG_DEBUG_NET set), the reference count is always
decremented, even when it's 1, allowing for consistent behavior and
potentially catching subtle SKB management bugs.
This modification enhances debugging capabilities for networking code
without impacting performance in production kernels. It helps kernel
developers identify and diagnose issues related to SKB management and
reference counting in the network stack.
