Artem Bityutskiy 301de5465f docs: trace: fix event state structure name
The documentation refers to a non-existent 'struct synth_trace_state'
structure. The correct name is 'struct synth_event_trace_state'.

In other words, this patch is a mechanical substitution:
s/synth_trace_state/synth_event_trace_state/g

Mauro Carvalho Chehab ca90857779 scripts: get_feat.pl: use its implementation for list-arch.sh
Add support for the same output format as the bash script,
and use its implementation instead of the previous one.

I opted to do such patch in order to have a single script
responsible for parsing Documentation/features and
produce different outputs.

As someone may rely on the past format, which is easy
to parse it, get_feat.pl now gains a new command with
the same output format as the previous script.

As a side effect, the perl script is a lot faster, as it reads
each file only once, instead of parsing files several times
via a for command and grep commands inside it.

This patch also changes the features list order to be
case-insensitive, in order to better match the output of
the existing script.

Nícolas F. R. A. Prado fb568273c0 docs: automarkup.py: Allow automatic cross-reference inside C namespace
Sphinx 3.1 introduced namespaces for C cross-references. With this,
each C domain type/function declaration is put inside the namespace that
was active at the time of its declaration.

Add support for automatic cross-referencing inside C namespaces by
checking whether the corresponding source file had a C namespace Sphinx
directive, and if so, try cross-referencing inside of it before going to
the global scope.

This assumes there's only one namespace (if any) per rst file.

Linus Torvalds 41f1653024 Networking fixes for 5.10-rc3, including fixes from wireless, can,
and netfilter subtrees.
 
 Current release - bugs in new features:
 
  - can: isotp: isotp_rcv_cf(): enable RX timeout handling in
    listen-only mode
 
 Previous release - regressions:
 
  - mac80211:
    - don't require VHT elements for HE on 2.4 GHz
    - fix regression where EAPOL frames were sent in plaintext
 
  - netfilter:
    - ipset: Update byte and packet counters regardless of whether
      they match
 
  - ip_tunnel: fix over-mtu packet send by allowing fragmenting even
    if inner packet has IP_DF (don't fragment) set in its header
    (when TUNNEL_DONT_FRAGMENT flag is not set on the tunnel dev)
 
  - net: fec: fix MDIO probing for some FEC hardware blocks
 
  - ip6_tunnel: set inner ipproto before ip6_tnl_encap to un-break
    gso support
 
  - sctp: Fix COMM_LOST/CANT_STR_ASSOC err reporting on big-endian
    platforms, sparse-related fix used the wrong integer size
 
 Previous release - always broken:
 
  - netfilter: use actual socket sk rather than skb sk when routing
    harder
 
  - r8169: work around short packet hw bug on RTL8125 by padding frames
 
  - net: ethernet: ti: cpsw: disable PTPv1 hw timestamping
    advertisement, the hardware does not support it
 
  - chelsio/chtls: fix always leaking ctrl_skb and another leak caused
    by a race condition
 
  - fix drivers incorrectly writing into skbs on TX:
    - cadence: force nonlinear buffers to be cloned
    - gianfar: Account for Tx PTP timestamp in the skb headroom
    - gianfar: Replace skb_realloc_headroom with skb_cow_head for PTP
 
  - can: flexcan:
    - remove FLEXCAN_QUIRK_DISABLE_MECR quirk for LS1021A
    - add ECC initialization for VF610 and LX2160A
    - flexcan_remove(): disable wakeup completely
 
  - can: fix packet echo functionality:
    - peak_canfd: fix echo management when loopback is on
    - make sure skbs are not freed in IRQ context in case they need
      to be dropped
    - always clone the skbs to make sure they have a reference on
      the socket, and prevent it from disappearing
    - fix real payload length return value for RTR frames
 
  - can: j1939: return failure on bind if netdev is down, rather than
    waiting indefinitely
 
 Misc:
 
  - IPv6: reply ICMP error if the first fragment don't include all
    headers to improve compliance with RFC 8200

 Getting to this point has required a lot of work; once there, hopefully we
 can keep things that way.
 
 I have packaged this as a separate pull because it does a fair amount of
 reaching outside of Documentation/.  The changes are all in comments and in
 code placement.  It's all been in linux-next since last week.
