The only usage of these structs is to assign their address to the
thermal_zone_attribute_groups array, which consists of pointers to
const, so make them const to allow the compiler to put them in read-only

The PID coefficients should be estimated again when there was a change to

The sustainable power value might come from the Device Tree or can be
estimated in run time. The sustainable power might be updated by the user
via sysfs interface, which should trigger new estimation of PID
coefficients. There is no need to estimate it every time when the
governor is called and temperature is high. Instead, store the estimated
value and make it available via standard sysfs interface, so it can be
checked from the user-space.

Intelligent Power Allocation (IPA) is built around the PID controller
concept. The initialization code tries to setup the environment based on
the information available in DT or estimate the value based on minimum
power reported by each of the cooling device. The estimation will have an
impact on the PID controller behaviour via the related 'k_po', 'k_pu',
'k_i' coefficients and also on the power budget calculation.

This change prevents the situation when 'k_i' is relatively big compared
to 'k_po' and 'k_pu' values. This might happen when the estimation for
'sustainable_power' returned small value, thus 'k_po' and 'k_pu' are
small.

I noticed that I couldn't read the PCH temperature on my workstation

through IPMI. Looking at the data sheet, it looks to me like the
existing intel PCH thermal driver should work without changes for
Lewisburg.

I suspect there's some other PCI IDs missing. But I hope somebody at

When system tries to enter S0ix suspend state, just after active load
scenarios, it fails due to PCH current temperature is higher than set
threshold.
This patch introduces delay loop mechanism that allows PCH temperature
to go down below threshold during suspend so it won't fail to enter S0ix.
Add delay loop timeout and count as module parameters for user to tune it,
if required based on system design. This change notifies the different
warning messages like when PCH temperature above the threshold and
executing delay loop. Also, notify the messages when it success or
failure for S0ix entry.
Previously out of 1000 runs around 3 to 5 times it might fail to enter
S0ix just after heavy workload. With this change, S0ix failures reduced
as PCH cools down below threshold.

On RT or even on mainline with 'threadirqs' on the command line all
interrupts which are not explicitly requested with IRQF_NO_THREAD
run their handlers in thread context. The same applies to soft interrupts.
That means they are subject to the normal scheduler rules and no other

  commit that used to take noise from the fast_pool (f227e3ec) was
  reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is
  fed from various sources of activities (networking, scheduling) to
  perturb the SipHash state using fast, non-trivially predictable data,
  instead of keeping it fully deterministic. The goal is essentially to
  make any occasional memory leakage or brute-force attempt useless.

  The resulting code was verified to be very slightly faster on x86_64

Commit 21653a41 ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().

But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().

Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.

This fixes the Microsoft Surface Go 2 hanging at boot.
