Since commit 6c5f05a6cd ("ARM: imx3: Remove imx3 soc_init()")
there are no more users of struct sdma_script_start_addrs outside
of the driver itself, thus let's move the struct declaration just
to the driver source code and remove the header file as unused one.

There's no need to restore DMA context on CPU_CLUSTER_PM_ENTER_FAILED as
the DMA context won't be lost on errors.
Note that this does not cause invalid context restore as we already check
for busy DMA with omap_dma_busy() in CPU_CLUSTER_PM_ENTER, and block any
deeper idle states for the SoC by returning NOTIFY_BAD if busy.
If other drivers block deeper idle states with cpu_pm, we now just do a
pointless restore, but only if dma was not busy on CPU_CLUSTER_PM_ENTER.
Let's update the CPU_CLUSTER_PM_ENTER_FAILED handling for correctness,
and add a comment.

The hardware retrigger is inherently racy with the vsync interrupt. This
isn't an issue as the hardware provides a way to detect a race loss and
handle it correctly. When debugging issues related to this, it's useful
to get a notification of the race loss. Add a debug message to do so.

Commit b9d79e4ca4 ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between

warns about it:

"A set of locking related fixes and updates:
- Two fixes for the futex syscall related to the timeout handling.
FUTEX_LOCK_PI does not support the FUTEX_CLOCK_REALTIME bit and
because it's not set the time namespace adjustment for clock
MONOTONIC is applied wrongly.
FUTEX_WAIT cannot support the FUTEX_CLOCK_REALTIME bit because its
always a relative timeout.
- Cleanups in the futex syscall entry points which became obvious
when the two timeout handling bugs were fixed.
- Cleanup of queued_write_lock_slowpath() as suggested by Linus

intel_dp_check_mst_status() uses a 14-byte array to read the DPRX Event
Status Indicator data, but then passes that buffer at offset 10 off as
an argument to drm_dp_channel_eq_ok().
End result: there are only 4 bytes remaining of the buffer, yet
drm_dp_channel_eq_ok() wants a 6-byte buffer. gcc-11 correctly warns
about this case:

This commit just extends the original array by 2 zero-initialized bytes,
avoiding the warning.
There may be some underlying bug in here that caused this confusion, but
this is at least no worse than the existing situation that could use

Mounting with "multichannel" is obviously implied if user requested
more than one channel on mount (ie mount parm max_channels>1).
Currently both have to be specified. Fix that so that if max_channels
is greater than 1 on mount, enable multichannel rather than silently
falling back to non-multichannel.

Pull networking fixes from Jakub Kicinski:
"Networking fixes for 5.13-rc1, including fixes from bpf, can and
netfilter trees. Self-contained fixes, nothing risky.
Current release - new code bugs:
- dsa: ksz: fix a few bugs found by static-checker in the new driver
- stmmac: fix frame preemption handshake not triggering after
interface restart
Previous releases - regressions:
- make nla_strcmp handle more then one trailing null character
- fix stack OOB reads while fragmenting IPv4 packets in openvswitch
and net/sched

- sctp: delay auto_asconf init until binding the first addr
- stmmac: clear receive all(RA) bit when promiscuous mode is off
- can: mcp251x: fix resume from sleep before interface was brought up
Previous releases - always broken:
- bpf: fix leakage of uninitialized bpf stack under speculation
- bpf: fix masking negation logic upon negative dst register
- netfilter: don't assume that skb_header_pointer() will never fail
- only allow init netns to set default tcp cong to a restricted algo
- xsk: fix xp_aligned_validate_desc() when len == chunk_size to avoid
false positive errors
- ethtool: fix missing NLM_F_MULTI flag when dumping
- can: m_can: m_can_tx_work_queue(): fix tx_skb race condition
- sctp: fix a SCTP_MIB_CURRESTAB leak in sctp_sf_do_dupcook_b
- bridge: fix NULL-deref caused by a races between assigning
rx_handler_data and setting the IFF_BRIDGE_PORT bit
Latecomer:
- seg6: add counters support for SRv6 Behaviors"

<linux/kconfig.h> is included from all the kernel-space source files,
including C, assembly, linker scripts. It is intended to contain a
minimal set of macros to evaluate CONFIG options.
IF_ENABLED() is an intruder here because (x ? y : z) is C code, which
should not be included from assembly files or linker scripts.
Also, <linux/kconfig.h> is no longer self-contained because NULL is
defined in <linux/stddef.h>.
Move IF_ENABLED() out to <linux/kernel.h> as PTR_IF(). PTF_IF()
takes the general boolean expression instead of a CONFIG option
so that it fits better in <linux/kernel.h>.

Merge master back into next, this allows us to resolve some conflicts in
arch/powerpc/Kconfig, and also re-sort the symbols under config PPC so
that they are in alphabetical order again.

Intel Wired LAN Driver Updates 2021-05-07
This series contains updates to i40e driver only.
Magnus fixes XDP by adding and correcting checks that were caused by a
previous commit which introduced a new variable but did not account for
it in all paths.
Yunjian Wang adds a return in an error path to prevent reading a freed
pointer.
Jaroslaw forces link reset when changing FEC so that changes take
affect.
Mateusz fixes PHY types for 2.5G and 5G as there is a differentiation on
PHY identifiers based on operation.
Arkadiusz removes filtering of LLDP frames for software DCB as this is
preventing them from being properly transmitted.

The RX FIFO overflows when the system is not able to process all received
packets and they start accumulating (first in the DMA queue in memory,
then in the FIFO). An interrupt is then raised for each overflowing packet
and handled in stmmac_interrupt(). This is counter-productive, since it
brings the system (or more likely, one CPU core) to its knees to process
the FIFO overflow interrupts.
stmmac_interrupt() handles overflow interrupts by writing the rx tail ptr
into the corresponding hardware register (according to the MAC spec, this
has the effect of restarting the MAC DMA). However, without freeing any rx
descriptors, the DMA stops right away, and another overflow interrupt is
raised as the FIFO overflows again. Since the DMA is already restarted at
the end of stmmac_rx_refill() after freeing descriptors, disabling FIFO
overflow interrupts and the corresponding handling code has no side effect,
and eliminates the interrupt storm when the RX FIFO overflows.

If userspace exits before calling accept() on a listener that had at least
one new connection ready, we get:
Attempt to release TCP socket in state 8
This happens because the mptcp socket gets cloned when the TCP connection
is ready, but the socket is never exposed to userspace.
The client additionally sends a DATA_FIN, which brings connection into
CLOSE_WAIT state. This in turn prevents the orphan+state reset fixup
in mptcp_sock_destruct() from doing its job.
