4a1288f1c1 dell-smm-hwmon: Add documentation
Part of the documentation is taken from the README of the userspace
utils (https://github.com/vitorafsr/i8kutils). The license is GPL-2+
and the author Massimo Dal Zotto is already credited as author of
the module. Therefore there should be no copyright problem.

I also added a paragraph with specific information on the experimental
support for automatic BIOS fan control.

51e46c7a40 docs, parallelism: Rearrange how jobserver reservations are made
Rasmus correctly observed that the existing jobserver reservation only
worked if no other build targets were specified. The correct approach
is to hold the jobserver slots until sphinx has finished. To fix this,
the following changes are made:

- refactor (and rename) scripts/jobserver-exec to set an environment
  variable for the maximally reserved jobserver slots and exec a
  child, to release the slots on exit.

- create Documentation/scripts/parallel-wrapper.sh which examines both
  $PARALLELISM and the detected "-jauto" logic from Documentation/Makefile
  to decide sphinx's final -j argument.

- chain these together in Documentation/Makefile

72ea91afbf PCI/ASPM: Add sysfs attributes for controlling ASPM link states
Add sysfs attributes to Endpoints and other Upstream Ports to control ASPM,
Clock PM, and L1 PM Substates.  The new attributes are:

  /sys/devices/pci*/.../link/clkpm
  /sys/devices/pci*/.../link/l0s_aspm
  /sys/devices/pci*/.../link/l1_aspm
  /sys/devices/pci*/.../link/l1_1_aspm
  /sys/devices/pci*/.../link/l1_2_aspm
  /sys/devices/pci*/.../link/l1_1_pcipm
  /sys/devices/pci*/.../link/l1_2_pcipm

An attribute is only visible if both ends of the Link leading to the device
support the state.  Writing y/1/on to the file enables the state; n/0/off
disables it.

These attributes can be used to tune the power/performance tradeoff for
individual devices.

b686631865 block: add iostat counters for flush requests
Requests that triggers flushing volatile writeback cache to disk (barriers)
have significant effect to overall performance.

Block layer has sophisticated engine for combining several flush requests
into one. But there is no statistics for actual flushes executed by disk.
Requests which trigger flushes usually are barriers - zero-size writes.

This patch adds two iostat counters into /sys/class/block/$dev/stat and
/proc/diskstats - count of completed flush requests and their total time.

8795a739e5 powerpc/sysdev: drop simple gpio
There is a config item CONFIG_SIMPLE_GPIO which
provides simple memory mapped GPIOs specific to powerpc.

However, the only platform which selects this option is
mpc5200, and this platform doesn't use it.

There are three boards calling simple_gpiochip_init(), but
as they don't select CONFIG_SIMPLE_GPIO, this is just a nop.

Simple_gpio is just redundant with the generic MMIO GPIO
driver which can be found in driver/gpio/ and selected via
CONFIG_GPIO_GENERIC_PLATFORM, so drop simple_gpio driver.

The main changes are:

1) Addition of BPF trampoline which works as a bridge between kernel functions,
   BPF programs and other BPF programs along with two new use cases: i) fentry/fexit
   BPF programs for tracing with practically zero overhead to call into BPF (as
   opposed to k[ret]probes) and ii) attachment of the former to networking related
   programs to see input/output of networking programs (covering xdpdump use case),
   from Alexei Starovoitov.

2) BPF array map mmap support and use in libbpf for global data maps; also a big
   batch of libbpf improvements, among others, support for reading bitfields in a
   relocatable manner (via libbpf's CO-RE helper API), from Andrii Nakryiko.

3) Extend s390x JIT with usage of relative long jumps and loads in order to lift
   the current 64/512k size limits on JITed BPF programs there, from Ilya Leoshkevich.

4) Add BPF audit support and emit messages upon successful prog load and unload in
   order to have a timeline of events, from Daniel Borkmann and Jiri Olsa.

5) Extension to libbpf and xdpsock sample programs to demo the shared umem mode
   (XDP_SHARED_UMEM) as well as RX-only and TX-only sockets, from Magnus Karlsson.

6) Several follow-up bug fixes for libbpf's auto-pinning code and a new API
   call named bpf_get_link_xdp_info() for retrieving the full set of prog
   IDs attached to XDP, from Toke Høiland-Jørgensen.

7) Add BTF support for array of int, array of struct and multidimensional arrays
   and enable it for skb->cb[] access in kfree_skb test, from Martin KaFai Lau.

dc68b40678 PCI/PM: Correct pci_pm_thaw_noirq() documentation
According to the documentation, pci_pm_thaw_noirq() did not put the device
into the full-power state and restore its standard configuration registers.
This is incorrect, so update the documentation to match the code.

ef63fe72f6 dt-bindings: net: ti: add new cpsw switch driver bindings
Add bindings for the new TI CPSW switch driver. Comparing to the legacy
bindings (net/cpsw.txt):
- ports definition follows DSA bindings (net/dsa/dsa.txt) and ports can be
marked as "disabled" if not physically wired.
- all deprecated properties dropped;
- all legacy propertiies dropped which represent constant HW cpapbilities
(cpdma_channels, ale_entries, bd_ram_size, mac_control, slaves,
active_slave)
- TI CPTS DT properties are reused as is, but grouped in "cpts" sub-node
- TI Davinci MDIO DT bindings are reused as is, because Davinci MDIO is
reused.
