of: reserved-memory: Add stub for RESERVEDMEM_OF_DECLARE()

The reserved-memory Kconfig could be disabled when drivers are
compile-tested. In this case RESERVEDMEM_OF_DECLARE() produces a
noisy warning about the orphaned __reservedmem_of_table section.
Add the missing stub that fixes the warning. In particular this is
needed for compile-testing of NVIDIA Tegra210 memory driver which
uses reserved-memory.

of: Fix truncation of memory sizes on 32-bit platforms

Variable "size" has type "phys_addr_t", which can be either 32-bit or
64-bit on 32-bit systems, while "unsigned long" is always 32-bit on
32-bit systems.  Hence the cast in

    (unsigned long)size / SZ_1M

may truncate a 64-bit size to 32-bit, as casts have a higher operator
precedence than divisions.

Fix this by inverting the order of the cast and division, which should
be safe for memory blocks smaller than 4 PiB.  Note that the division is
actually a shift, as SZ_1M is a power-of-two constant, hence there is no
need to use div_u64().

While at it, use "%lu" to format "unsigned long".

dt-bindings: mailbox: Convert omap-mailbox.txt binding to YAML

Convert the current OMAP Mailbox binding from text format to YAML
format/DT schema, and delete the legacy text binding file.

The new YAML binding conversion is an updated version compared to
the original. The descriptions for certain properties have been
improved to provide more clarity. Constraints are added to the
properties 'ti,mbox-num-users', 'ti,mbox-num-fifos' and 'interrupts'.
The 'ti,hwmods' is a legacy property and is retained only to reflect
the existing usage on some older OMAP2 and OMAP3 platforms.

All the existing examples have also been updated to reflect the
latest dts nodes (ti,hwmods removed from OMAP4 and AM33xx examples,
and interrupts value updated for AM65x SoCs).

Linux 5.13-rc1

fbmem: fix horribly incorrect placement of __maybe_unused

Commit b9d79e4ca4ff ("fbmem: Mark proc_fb_seq_ops as __maybe_unused")
places the '__maybe_unused' in an entirely incorrect location between
the "struct" keyword and the structure name.

It's a wonder that gcc accepts that silently, but clang quite reasonably
warns about it:

    drivers/video/fbdev/core/fbmem.c:736:21: warning: attribute declaration must precede definition [-Wignored-attributes]
    static const struct __maybe_unused seq_operations proc_fb_seq_ops = {
                        ^

Fix it.

     potentially mismatching scheduler state

   - Prevent an out-of-bounds access in uclamp caused bu a rounding

smb3: if max_channels set to more than one channel request multichannel

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.

  for a few weeks but got dropped due to conflicts. And there's also a

  Summary:

   - Remove the nvlink support now that it's only user has been removed.

   - Enable huge vmalloc mappings for Radix MMU (P9).

   - Fix KVM conversion to gfn-based MMU notifier callbacks.

   - Fix a kexec/kdump crash with hot plugged CPUs.

linux/kconfig.h: replace IF_ENABLED() with PTR_IF() in <linux/kernel.h>

<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>.

net: stmmac: Do not enable RX FIFO overflow interrupts

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.

mptcp: fix splat when closing unaccepted socket

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.

Fixes: 3721b9b64676b ("mptcp: Track received DATA_FIN sequence number and add related helpers")
