Pull thermal control changes for 5.20-rc1 from Daniel Lezcano:
"- Make per cpufreq / devfreq cooling device ops instead of using a
global variable, fix comments and rework the trace information
(Lukasz Luba)
- Add the include/dt-bindings/thermal.h under the area covered by the
thermal maintainer in the MAINTAINERS file (Lukas Bulwahn)
- Improve the error output by giving the sensor identification when a
thermal zone failed to initialize, the DT bindings by changing the
positive logic and adding the r8a779f0 support on the rcar3 (Wolfram
Sang)
- Convert the QCom tsens DT binding to the dtsformat format (Krzysztof
Kozlowski)
- Remove the pointless get_trend() function in the QCom, Ux500 and
tegra thermal drivers, along with the unused DROP_FULL and
RAISE_FULL trends definitions. Simplify the code by using clamp()
macros (Daniel Lezcano)
- Fix ref_table memory leak at probe time on the k3_j72xx bandgap
(Bryan Brattlof)
- Fix array underflow in prep_lookup_table (Dan Carpenter)
- Add static annotation to the k3_j72xx_bandgap_j7* data structure
(Jin Xiaoyun)
- Fix typos in comments detected on sun8i by Coccinelle (Julia Lawall)
- Fix typos in comments on rzg2l (Biju Das)
- Remove as unnecessary call to dev_err() as the error is already
printed by the failing function on u8500 (Yang Li)
- Register the thermal zones as hwmon sensors for the Qcom thermal
sensors (Dmitry Baryshkov)
- Fix 'tmon' tool compilation issue by adding phtread.h include
(Markus Mayer)
- Fix typo in the comments for the 'tmon' tool (Slark Xiao)
- Consolidate the thermal core code by beginning to move the thermal
trip structure from the thermal OF code as a generic structure to be
used by the different sensors when registering a thermal zone
(Daniel Lezcano)"

Now that we have the thermal trip stored in the thermal zone in a
generic way, we can rely on them and remove one indirection we found
in the thermal_of code and do one more step forward the removal of the
duplicated structures.

The thermal trip points are properties of a thermal zone and the
different sub systems should be able to save them in the thermal zone
structure instead of having their own definition.
Give the opportunity to the drivers to create a thermal zone with
thermal trips which will be accessible directly from the thermal core
framework.
As we added the thermal trip points structure in the thermal zone,
let's extend the thermal zone register function to have the thermal
trip structures as a parameter and store it in the 'trips' field of
the thermal zone structure.
The thermal zone contains the trip point, we can store them directly
when registering the thermal zone. That will allow another step
forward to remove the duplicate thermal zone structure we find in the
thermal_of code.

The thermal_of code builds a trip array associated with the node
pointer in order to compare the trip point phandle with the list.
The thermal trip is a thermal zone property and should be moved
there. If some sensors have hardcoded trip points, they should use the
exported structure instead of redefining again and again their own
structure and data to describe exactly the same things.
In order to move this to the thermal.h header and allow more cleanup,
we need to remove the node pointer from the structure.
Instead of building storing the device node, we search directly in the
device tree the corresponding node. That results in a simplification
of the code and allows to move the structure to thermal.h

Simplify the thermal_power_cpu_get_power trace event by removing
complicated cpumask and variable length array. Now the tools parsing trace
output don't have to hassle to get this power data. The simplified format
version uses 'policy->cpu'. Remove also the 'load' information completely
since there is very little value of it in this trace event. To get the
CPUs' load (or utilization) there are other dedicated trace hooks in the
kernel. This patch also simplifies and speeds-up the main cooling code
when that trace event is enabled.
Rename the trace event to avoid confusion of tools which parse the trace
file.

system is more beneficial from the energy saving perspective than using
low-power S0 idle, as long as S3 is supported.
Suspend-to-idle is still a valid suspend mode if ACPI_FADT_LOW_POWER_S0
is not set and the pm_suspend_via_firmware() check in pch_wpt_suspend()
is sufficient to distinguish suspend-to-idle from S3, so drop the
confusing ACPI_FADT_LOW_POWER_S0 check.

This is a collection of three fixes for small annoyances.
Two of these are already pending in other trees, but I really don't want
to release another -rc with these issues pending, so I picked up the
patches for these things directly. We'll end up with duplicate commits
eventually, I prefer that over having these issues pending.
The third one is just me getting rid of another BUG_ON() just because it
was reported and I dislike those things so much.
* merge 'hot-fixes' branch:
ida: don't use BUG_ON() for debugging
drm/aperture: Run fbdev removal before internal helpers
ptrace: fix clearing of JOBCTL_TRACED in ptrace_unfreeze_traced()

This is another old BUG_ON() that just shouldn't exist (see also commit
a382f8fee42c: "signal handling: don't use BUG_ON() for debugging").
In fact, as Matthew Wilcox points out, this condition shouldn't really
even result in a warning, since a negative id allocation result is just
a normal allocation failure:
"I wonder if we should even warn here -- sure, the caller is trying to
free something that wasn't allocated, but we don't warn for
kfree(NULL)"
and goes on to point out how that current error check is only causing
people to unnecessarily do their own index range checking before freeing
it.
This was noted by Itay Iellin, because the bluetooth HCI socket cookie
code does *not* do that range checking, and ends up just freeing the
error case too, triggering the BUG_ON().
The HCI code requires CAP_NET_RAW, and seems to just result in an ugly
splat, but there really is no reason to BUG_ON() here, and we have
generally striven for allocation models where it's always ok to just do
free(alloc());
even if the allocation were to fail for some random reason (usually
obviously that "random" reason being some resource limit).
Fixes: 88eca0207cf1 ("ida: simplified functions for id allocation")

Pull x86 fixes from Borislav Petkov:
- Prepare for and clear .brk early in order to address XenPV guests
failures where the hypervisor verifies page tables and uninitialized
data in that range leads to bogus failures in those checks
- Add any potential setup_data entries supplied at boot to the identity
pagetable mappings to prevent kexec kernel boot failures. Usually,
this is not a problem for the normal kernel as those mappings are
part of the initially mapped 2M pages but if kexec gets to allocate
the second kernel somewhere else, those setup_data entries need to be
mapped there too.
- Fix objtool not to discard text references from the __tracepoints
section so that ENDBR validation still works
- Correct the setup_data types limit as it is user-visible, before 5.19
releases
