[ Upstream commit 3595c559326d0b660bb088a88e22e0ca630a0e35 ]
The warning added in commit 3b0e761ba83
"dlm: print log message when cluster name is not set"
did not account for the fact that lockspaces created
from userland do not supply a cluster name, so bogus
warnings are printed every time a userland lockspace
is created.

There's a bug in dtc in checking for duplicate node names when there's
another section (e.g. "/ { };"). In this case, skeleton.dtsi provides
another section. Upon removal of skeleton.dtsi, the dtb fails to build
due to a duplicate node 'fixedregulator@0'. As both nodes were pretty
much the same 3.3V fixed regulator, it hasn't really mattered. Fix this
by renaming the nodes to something unique. In the process, drop the
unit-address which shouldn't be present wtihout reg property.

Building a single target in an external module fails due to missing
.tmp_versions directory.
For example,
$ make -C /lib/modules/$(uname -r)/build M=$PWD foo.o
will fail in the following way:
CC [M] /home/masahiro/foo/foo.o
/bin/sh: 1: cannot create /home/masahiro/foo/.tmp_versions/foo.mod: Directory nonexistent

[ Upstream commit a4d26f1a0958bb1c2b60c6f1e67c6f5d43e2647b ]
During development of a serial console driver with a gcc 8.2.0
toolchain for RISC-V, the following modpost warning appeared:
----
WARNING: vmlinux.o(.data+0x19b10): Section mismatch in reference from the variable .LANCHOR1 to the function .init.text:sifive_serial_console_setup()
The variable .LANCHOR1 references
the function __init sifive_serial_console_setup()
If the reference is valid then annotate the
variable with __init* or __refdata (see linux/init.h) or name the variable:
*_template, *_timer, *_sht, *_ops, *_probe, *_probe_one, *_console
----
".LANCHOR1" is an ELF local symbol, automatically created by gcc's section
anchor generation code:
https://gcc.gnu.org/onlinedocs/gccint/Anchored-Addresses.htmlhttps://gcc.gnu.org/git/?p=gcc.git;a=blob;f=gcc/varasm.c;h=cd9591a45617464946dcf9a126dde277d9de9804;hb=9fb89fa845c1b2e0a18d85ada0b077c84508ab78#l7473
This was verified by compiling the kernel with -fno-section-anchors
and observing that the ".LANCHOR1" ELF local symbol disappeared, and
modpost no longer warned about the section mismatch. The serial
driver code idiom triggering the warning is standard Linux serial
driver practice that has a specific whitelist inclusion in modpost.c.
I'm neither a modpost nor an ELF expert, but naively, it doesn't seem
useful for modpost to report section mismatch warnings caused by ELF
local symbols by default. Local symbols have compiler-generated
names, and thus bypass modpost's whitelisting algorithm, which relies
on the presence of a non-autogenerated symbol name. This increases
the likelihood that false positive warnings will be generated (as in
the above case).
Thus, disable section mismatch reporting on ELF local symbols. The
rationale here is similar to that of commit 2e3a10a1551d ("ARM: avoid
ARM binutils leaking ELF local symbols") and of similar code already
present in modpost.c:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/scripts/mod/modpost.c?h=v4.19-rc4&id=7876320f88802b22d4e2daf7eb027dd14175a0f8#n1256

[ Upstream commit e1561fe2dd69dc5dddd69bd73aa65355bdfb048b ]
Previously the SNMP TCPTIMEOUTS counter has inconsistent accounting:
1. It counts all SYN and SYN-ACK timeouts
2. It counts timeouts in other states except recurring timeouts and
timeouts after fast recovery or disorder state.
Such selective accounting makes analysis difficult and complicated. For
example the monitoring system needs to collect many other SNMP counters
to infer the total amount of timeout events. This patch makes TCPTIMEOUTS
counter simply counts all the retransmit timeout (SYN or data or FIN).

Current rsnd dvc.c is using flags to avoid duplicating register for
MIXer case. OTOH, commit e894efef9ac7 ("ASoC: core: add support to card
rebind") allows to rebind sound card without rebinding all drivers.
Because of above patch and dvc.c flags, it can't re-register kctrl if
only sound card was rebinded, because dvc is keeping old flags.
(Of course it will be no problem if rsnd driver also be rebinded,
but it is not purpose of above patch).
This patch checks current card registered kctrl when registering.
In MIXer case, it can avoid duplicate register if card already has same
kctrl. In rebind case, it can re-register kctrl because card registered
kctl had been removed when unbinding.
This patch is updated version of commit b918f1bc7f1ce ("ASoC: rsnd: DVC

A closer look into the sata_dwc_460ex code revealed that
the driver did initally set the correct protection control
bits. However, this feature was lost when the sata_dwc_460ex
driver was converted to the generic DMA driver framework.

[ Upstream commit 627469e4445b9b12e0229b3bdf8564d5ce384dd7 ]
The function coh901318_alloc_chan_resources() calls spin_lock_irqsave()
before calling coh901318_config().
But coh901318_config() calls spin_lock_irqsave() again in its
definition, which may cause a double-lock bug.
Because coh901318_config() is only called by
coh901318_alloc_chan_resources(), the bug fix is to remove the
calls to spin-lock and -unlock functions in coh901318_config().

The CEC specification requires that the Vendor ID (if any) is reported
after a logical address was claimed.
This was never done, so add support for this.

In case of error, we return 0.
This is spurious and not consistent with the other functions of the driver.
Propagate the error code instead.

_FP_ROUND_ZERO is defined as 0 and used as a statemente in macro
_FP_ROUND. This generates "error: statement with no effect
[-Werror=unused-value]" from gcc. Defining _FP_ROUND_ZERO as (void)0 to
fix it.

In smc_wr_tx_put_slot() field pend->idx is used after being

This results in a broken administration of available WR send
