1a3232d2f6 ASoC: topology: Add support for TLV bytes controls
Allow vendor drivers to define bespoke bytes ext handlers and IDs for
TLV bytes controls. And the topology core will bind these handlers by
matching IDs defined by the vendor driver and user space topology
data file.

And TLV callback binding is moved to soc_tplg_kcontrol_bind_io(). This
function process all handler binding now.

2f064f3485 mm: make page pfmemalloc check more robust
Commit c48a11c7ad ("netvm: propagate page->pfmemalloc to skb") added
checks for page->pfmemalloc to __skb_fill_page_desc():

        if (page->pfmemalloc && !page->mapping)
                skb->pfmemalloc = true;

It assumes page->mapping == NULL implies that page->pfmemalloc can be
trusted.  However, __delete_from_page_cache() can set set page->mapping
to NULL and leave page->index value alone.  Due to being in union, a
non-zero page->index will be interpreted as true page->pfmemalloc.

So the assumption is invalid if the networking code can see such a page.
And it seems it can.  We have encountered this with a NFS over loopback
setup when such a page is attached to a new skbuf.  There is no copying
going on in this case so the page confuses __skb_fill_page_desc which
interprets the index as pfmemalloc flag and the network stack drops
packets that have been allocated using the reserves unless they are to
be queued on sockets handling the swapping which is the case here and
that leads to hangs when the nfs client waits for a response from the
server which has been dropped and thus never arrive.

The struct page is already heavily packed so rather than finding another
hole to put it in, let's do a trick instead.  We can reuse the index
again but define it to an impossible value (-1UL).  This is the page
index so it should never see the value that large.  Replace all direct
users of page->pfmemalloc by page_is_pfmemalloc which will hide this
nastiness from unspoiled eyes.

The information will get lost if somebody wants to use page->index
obviously but that was the case before and the original code expected
that the information should be persisted somewhere else if that is
really needed (e.g.  what SLAB and SLUB do).

====================
Netfilter updates for net-next

This is second pull request includes the conflict resolution patch that
resulted from the updates that we got for the conntrack template through
kmalloc. No changes with regards to the previously sent 15 patches.

The following patchset contains Netfilter updates for your net-next tree, they
are:

1) Rework the existing nf_tables counter expression to make it per-cpu.

2) Prepare and factor out common packet duplication code from the TEE target so
   it can be reused from the new dup expression.

3) Add the new dup expression for the nf_tables IPv4 and IPv6 families.

4) Convert the nf_tables limit expression to use a token-based approach with
   64-bits precision.

5) Enhance the nf_tables limit expression to support limiting at packet byte.
   This comes after several preparation patches.

6) Add a burst parameter to indicate the amount of packets or bytes that can
   exceed the limiting.

7) Add netns support to nfacct, from Andreas Schultz.

8) Pass the nf_conn_zone structure instead of the zone ID in nf_tables to allow
   accessing more zone specific information, from Daniel Borkmann.

9) Allow to define zone per-direction to support netns containers with
   overlapping network addressing, also from Daniel.

10) Extend the CT target to allow setting the zone based on the skb->mark as a
   way to support simple mappings from iptables, also from Daniel.

11) Make the nf_tables payload expression aware of the fact that VLAN offload
    may have removed a vlan header, from Florian Westphal.

61adedf3e3 route: move lwtunnel state to dst_entry
Currently, the lwtunnel state resides in per-protocol data. This is
a problem if we encapsulate ipv6 traffic in an ipv4 tunnel (or vice versa).
The xmit function of the tunnel does not know whether the packet has been
routed to it by ipv4 or ipv6, yet it needs the lwtstate data. Moving the
lwtstate data to dst_entry makes such inter-protocol tunneling possible.

As a bonus, this brings a nice diffstat.

Rename the ipv4_tos and ipv4_ttl fields to just 'tos' and 'ttl', as they'll
be used with IPv6 tunnels, too.

c1ea5d672a ip_tunnels: add IPv6 addresses to ip_tunnel_key
Add the IPv6 addresses as an union with IPv4 ones. When using IPv4, the
newly introduced padding after the IPv4 addresses needs to be zeroed out.

ac1cf3990c ip_tunnels: remove custom alignment and packing
The custom alignment of struct ip_tunnel_key is unnecessary. In struct
sw_flow_key, it starts at offset 256, in struct ip_tunnel_info it's the
first field.

The structure is also packed even without the __packed keyword.

A proprietary vendor command may send back useful data to the user

For example, the field level applied on the NFC router antenna.

Still based on net/wireless/nl80211.c implementation,
add nfc_vendor_cmd_alloc_reply_skb and nfc_vendor_cmd_reply in

 "Here are a small collecton of sound fix patches.

  The most significant one is the disablement of newly introduced
  topology API.  Its ABI couldn't be stabilized enough, so we decided to
  delay for 4.3 in the end.  Other than that, all oneliner fixes: a
  USB-audio runtime PM fix and a couple of HD-audio quirks"

5de490daec pmem: add copy_from_iter_pmem() and clear_pmem()
Add support for two new PMEM APIs, copy_from_iter_pmem() and
clear_pmem().  copy_from_iter_pmem() is used to copy data from an
iterator into a PMEM buffer.  clear_pmem() zeros a PMEM memory range.

Both of these new APIs must be explicitly ordered using a wmb_pmem()
function call and are implemented in such a way that the wmb_pmem()
will make the stores to PMEM durable.  Because both APIs are unordered
they can be called as needed without introducing any unwanted memory
barriers.

18279b467a pmem: remove layer when calling arch_has_wmb_pmem()
Prior to this change arch_has_wmb_pmem() was only called by
arch_has_pmem_api().  Both arch_has_wmb_pmem() and arch_has_pmem_api()
checked to make sure that CONFIG_ARCH_HAS_PMEM_API was enabled.

Instead, remove the old arch_has_wmb_pmem() wrapper to be rid of one
extra layer of indirection and the redundant CONFIG_ARCH_HAS_PMEM_API
check. Rename __arch_has_wmb_pmem() to arch_has_wmb_pmem() since we no
longer have a wrapper, and just have arch_has_pmem_api() call the
architecture specific arch_has_wmb_pmem() directly.
