Kuniyuki Iwashima says:
====================
sysctl: Fix data-races around ipv4_net_table (Round 3).
This series fixes data-races around 21 knobs after
igmp_link_local_mcast_reports in ipv4_net_table.
These 4 knobs are skipped because they are safe.
- tcp_congestion_control: Safe with RCU and xchg().
- tcp_available_congestion_control: Read only.
- tcp_allowed_congestion_control: Safe with RCU and spinlock().
- tcp_fastopen_key: Safe with RCU and xchg()
So, round 4 will start with fib_multipath_use_neigh.

Merge "Sunplus SP7021 SoC support" from Qin Jian, applied
as patches:
"Sunplus SP7021 is an ARM Cortex A7 (4 cores) based SoC. It integrates many
peripherals (ex: UART, I2C, SPI, SDIO, eMMC, USB, SD card and etc.) into a
single chip. It is designed for industrial control.
SP7021 consists of two chips (dies) in a package. One is called C-chip
(computing chip). It is a 4-core ARM Cortex A7 CPU. It adopts high-level
process (22 nm) for high performance computing. The other is called P-
chip (peripheral chip). It has many peripherals and an ARM A926 added
especially for real-time control. P-chip is made for customers. It adopts
low-level process (ex: 0.11 um) to reduce cost.

It was observed that by allowing pinctrl_amd to be loaded
later in the boot process that interrupts sent to the GPIO
controller early in the boot are not serviced. The kernel treats
these as a spurious IRQ and disables the IRQ.
This problem was exacerbated because it happened on a system with
an encrypted partition so the kernel object was not accesssible for
an extended period of time while waiting for a passphrase.
To avoid this situation from occurring, stop allowing pinctrl-amd
from being built as a module and instead require it to be built-in
or disabled.

The marvell PHY driver changes the LED[0] pin function to "On - 1000
Mbps Link, Off - Else".
Turris Omnia expects that the function is "On - Link, Blink - Activity,
Off - No link".
Use the `marvell,reg-init` DT property to change the function.
In the future, once netdev trigger will support HW offloading, we will
be able to have this configured via the combination of PHY driver and
leds-turris-omnia driver.

Socket destruction flow and tls_device_down function sync against each
other using tls_device_lock and the context refcount, to guarantee the
device resources are freed via tls_dev_del() by the end of
tls_device_down.
In the following unfortunate flow, this won't happen:
- refcount is decreased to zero in tls_device_sk_destruct.
- tls_device_down starts, skips the context as refcount is zero, going
all the way until it flushes the gc work, and returns without freeing
the device resources.
- only then, tls_device_queue_ctx_destruction is called, queues the gc
work and frees the context's device resources.
Solve it by decreasing the refcount in the socket's destruction flow
under the tls_device_lock, for perfect synchronization. This does not
slow down the common likely destructor flow, in which both the refcount
is decreased and the spinlock is acquired, anyway.

- The code relies on rc_pci_fixup being called, which only happens

PCIe controller and do not use pci-mvebu.c controller driver yet.

The blamed commit introduce support for lan966x which use the same
pinconf_ops as sparx5. The problem is that pinconf_ops is specific to
sparx5. More precisely the offset of the bits in the pincfg register are
different and also lan966x doesn't have support for
PIN_CONFIG_INPUT_SCHMITT_ENABLE.
Fix this by making pinconf_ops more generic such that it can be also
used by lan966x. This is done by introducing 'ocelot_pincfg_data' which
contains the offset and what is supported for each SOC.

The sys_clk frequency is 165.625MHz. The register reference of the
Generic Clock controller lists the CPU clock as 600MHz, the DDR clock as
300MHz and the SYS clock as 162.5MHz. This is wrong. It was first
noticed during the fan driver development and it was measured and
verified via the CLK_MON output of the SoC which can be configured to
output sys_clk/64.
The core PLL settings (which drives the SYS clock) seems to be as
follows:
DIVF = 52
DIVQ = 3
DIVR = 1
With a refernce clock of 25MHz, this means we have a post divider clock
Fpfd = Fref / (DIVR + 1) = 25MHz / (1 + 1) = 12.5MHz
The resulting VCO frequency is then
Fvco = Fpfd * (DIVF + 1) * 2 = 12.5MHz * (52 + 1) * 2 = 1325MHz
And the output frequency is
Fout = Fvco / 2^DIVQ = 1325MHz / 2^3 = 165.625Mhz
This all adds up to the constrains of the PLL:
10MHz <= Fpfd <= 200MHz
20MHz <= Fout <= 1000MHz
1000MHz <= Fvco <= 2000MHz

Since segment_pages is no longer a compile time constant, it looks the
DIV_ROUND_UP(node->size, segment_pages) breaks the 32b build. Simplest
is just to use the ULL variant, but really we should need not need more
than u32 for the page alignment (also we are limited by that due to the
sg->length type), so also make it all u32.

On powerpc, 'perf trace' is crashing with a SIGSEGV when trying to
process a perf.data file created with 'perf trace record -p':
#0 0x00000001225b8988 in syscall_arg__scnprintf_augmented_string <snip> at builtin-trace.c:1492
#1 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1492
#2 syscall_arg__scnprintf_filename <snip> at builtin-trace.c:1486
#3 0x00000001225bdd9c in syscall_arg_fmt__scnprintf_val <snip> at builtin-trace.c:1973
#4 syscall__scnprintf_args <snip> at builtin-trace.c:2041
#5 0x00000001225bff04 in trace__sys_enter <snip> at builtin-trace.c:2319
That points to the below code in tools/perf/builtin-trace.c:
/*
* If this is raw_syscalls.sys_enter, then it always comes with the 6 possible
* arguments, even if the syscall being handled, say "openat", uses only 4 arguments
* this breaks syscall__augmented_args() check for augmented args, as we calculate
* syscall->args_size using each syscalls:sys_enter_NAME tracefs format file,
* so when handling, say the openat syscall, we end up getting 6 args for the
* raw_syscalls:sys_enter event, when we expected just 4, we end up mistakenly
* thinking that the extra 2 u64 args are the augmented filename, so just check
* here and avoid using augmented syscalls when the evsel is the raw_syscalls one.
*/
if (evsel != trace->syscalls.events.sys_enter)
augmented_args = syscall__augmented_args(sc, sample, &augmented_args_size, trace->raw_augmented_syscalls_args_size);
As the comment points out, we should not be trying to augment the args
for raw_syscalls. However, when processing a perf.data file, we are not
initializing those properly. Fix the same.

The test does not always correctly determine the number of events for
hybrids, nor allow for more than 1 evsel when parsing.
Fix by iterating the events actually created and getting the correct
evsel for the events processed.
