Make the ACPI thermal zone driver use the .should_bind() thermal zone
callback to provide the thermal core with the information on whether or
not to bind the given cooling device to the given trip point in the
given thermal zone.  If it returns 'true', the thermal core will bind
the cooling device to the trip and the corresponding unbinding will be
taken care of automatically by the core on the removal of the involved
thermal zone or cooling device.

This replaces the .bind() and .unbind() thermal zone callbacks which
allows the code to be simplified quite significantly while providing
the same functionality.

The current design of the code binding cooling devices to trip points in
thermal zones is convoluted and hard to follow.

Namely, a driver that registers a thermal zone can provide .bind()
and .unbind() operations for it, which are required to call either
thermal_bind_cdev_to_trip() and thermal_unbind_cdev_from_trip(),
respectively, or thermal_zone_bind_cooling_device() and
thermal_zone_unbind_cooling_device(), respectively, for every relevant
trip point and the given cooling device.  Moreover, if .bind() is
provided and .unbind() is not, the cleanup necessary during the removal
of a thermal zone or a cooling device may not be carried out.

In other words, the core relies on the thermal zone owners to do the
right thing, which is error prone and far from obvious, even though all
of that is not really necessary.  Specifically, if the core could ask
the thermal zone owner, through a special thermal zone callback, whether
or not a given cooling device should be bound to a given trip point in
the given thermal zone, it might as well carry out all of the binding
and unbinding by itself.  In particular, the unbinding can be done
automatically without involving the thermal zone owner at all because
all of the thermal instances associated with a thermal zone or cooling
device going away must be deleted regardless.

Accordingly, introduce a new thermal zone operation, .should_bind(),
that can be invoked by the thermal core for a given thermal zone,
trip point and cooling device combination in order to check whether
or not the cooling device should be bound to the trip point at hand.
It takes an additional cooling_spec argument allowing the thermal
zone owner to specify the highest and lowest cooling states of the
cooling device and its weight for the given trip point binding.

Make the thermal core use this operation, if present, in the absence of
.bind() and .unbind().  Note that .should_bind() will be called under
the thermal zone lock.

Since thermal_bind_cdev_to_trip() and thermal_unbind_cdev_from_trip()
acquire the thermal zone lock, the locking rules for their callers get
complicated.  In particular, the thermal zone lock cannot be acquired
in any code path leading to one of these functions even though it might
be useful to do so.

To address this, remove the thermal zone locking from both these
functions, add lockdep assertions for the thermal zone lock to both
of them and make their callers acquire the thermal zone lock instead.

Introduce a facility allowing the thermal core functionality to be
exercised in a controlled way in order to verify its behavior, without
affecting its regular users noticeably.

It is based on the idea of preparing thermal zone templates along with
their trip points by writing to files in debugfs.  When ready, those
templates can be used for registering test thermal zones with the
thermal core.

The temperature of a test thermal zone created this way can be adjusted
via debugfs, which also triggers a __thermal_zone_device_update() call
for it.  By manipulating the temperature of a test thermal zone, one can
check if the thermal core reacts to the changes of it as expected.

In order to set the scene for the thresholds support which have to
manipulate the low and high temperature boundaries for the interrupt
support, we must pass the low and high values to the incoming
thresholds routine.

The variables are set from the thermal_zone_set_trips() where the
function loops the thermal trips to figure out the next and the
previous temperatures to set the interrupt to be triggered when they
are crossed.

These variables will be needed by the function in charge of handling
the thresholds in the incoming changes but they are local to the
aforementioned function thermal_zone_set_trips().

Move the low and high boundaries computation out of the function in
thermal_zone_device_update() so they are accessible from there.

The positive side effect is they are computed in the same loop as
handle_thermal_trip(), so we remove one loop.

After running once, the for_each_trip_desc() loop in
bang_bang_manage() is pure needless overhead because it is not going to
make any changes unless a new cooling device has been bound to one of
the trips in the thermal zone or the system is resuming from sleep.

For this reason, make bang_bang_manage() set governor_data for the
thermal zone and check it upfront to decide whether or not it needs to
do anything.

However, governor_data needs to be reset in some cases to let
bang_bang_manage() know that it should walk the trips again, so add an
.update_tz() callback to the governor and make the core additionally
invoke it during system resume.

To avoid affecting the other users of that callback unnecessarily, add
a special notification reason for system resume, THERMAL_TZ_RESUME, and
also pass it to __thermal_zone_device_update() called during system
resume for consistency.

After recent changes, the Bang-bang governor may not adjust the
initial configuration of cooling devices to the actual situation.

Namely, if a cooling device bound to a certain trip point starts in
the "on" state and the thermal zone temperature is below the threshold
of that trip point, the trip point may never be crossed on the way up
in which case the state of the cooling device will never be adjusted
because the thermal core will never invoke the governor's
.trip_crossed() callback.  [Note that there is no issue if the zone
temperature is at the trip threshold or above it to start with because
.trip_crossed() will be invoked then to indicate the start of thermal
mitigation for the given trip.]

To address this, add a .manage() callback to the Bang-bang governor
and use it to ensure that all of the thermal instances managed by the
governor have been initialized properly and the states of all of the
cooling devices involved have been adjusted to the current zone
temperature as appropriate.

 - Fix 32-bit PTI for real.

   pti_clone_entry_text() is called twice, once before initcalls so that
   initcalls can use the user-mode helper and then again after text is
   set read only. Setting read only on 32-bit might break up the PMD
   mapping, which makes the second invocation of pti_clone_entry_text()
   find the mappings out of sync and failing.

   Allow the second call to split the existing PMDs in the user mapping
   and synchronize with the kernel mapping.

 - Don't make acpi_mp_wake_mailbox read-only after init as the mail box
   must be writable in the case that CPU hotplug operations happen after
   boot. Otherwise the attempt to start a CPU crashes with a write to
   read only memory.

 - Add a missing sanity check in mtrr_save_state() to ensure that the
   fixed MTRR MSRs are supported.

   Otherwise mtrr_save_state() ends up in a #GP, which is fixed up, but

   adjtimex() uses not the proper constant and uses CLOCK_REALTIME

to a sourcecfg register of an APLIC might (or might not) cause the
corresponding interrupt-pending bit to be set to one if the rectified
input value is high (= 1) under the new source mode."

When the interrupt type is changed in the sourcecfg register, the APLIC
device might not set the corresponding pending bit, so the interrupt might
never become pending.

To handle sourcecfg register changes for level-triggered interrupts in MSI
mode, manually set the pending bit for retriggering interrupt so it gets
retriggered if it was already asserted.

The data type of the mask is u32 and the number of supported interrupts is

a mismatch warning. The out of bounds condition is also reported by UBSAN:

Pull spi fixes from Mark Brown:
 "A few SPI fixes: clock rate calculation fixes for the Kunpeng and lpsi
  drivers and a missing registration of a device ID for spidev (which
  had only been updated for DT cases, causing warnings)"

* tag 'spi-fix-v6.11-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi:
  spi: spi-fsl-lpspi: Fix scldiv calculation
  spi: spidev: Add missing spi_device_id for bh2228fv
  spi: hisi-kunpeng: Add verification for the max_frequency provided by the firmware
  spi: hisi-kunpeng: Add validation for the minimum value of speed_hz

bcachefs_metadata_version_disk_accounting_v2 erroneously had padding
bytes in disk_accounting_key, which is a problem because we have to
guarantee that all unused bytes in disk_accounting_key are zeroed.

Fortunately 6.11 isn't out yet, so it's cheap to fix this by spinning a
new version.
