Pull thermal control updates from Rafael Wysocki:
"As far as new functionality is concerned, there is a new thermal
driver for the Intel Hardware Feedback Interface (HFI) along with some
intel-speed-select utility changes to support it. There are also new
DT compatible strings for a couple of platforms, and thermal zones on
some platforms will be registered as HWmon sensors now.
Apart from the above, some drivers are updated (fixes mostly) and
there is a new piece of documentation for the Intel DPTF (Dynamic
Power and Thermal Framework) sysfs interface.
Specifics:
- Add a new thermal driver for the Intel Hardware Feedback Interface
(HFI) including the HFI initialization, HFI notification interrupt
handling and sending CPU capabilities change messages to user space
via the thermal netlink interface (Ricardo Neri, Srinivas
Pandruvada, Nathan Chancellor, Randy Dunlap).
- Extend the intel-speed-select utility to handle out-of-band CPU
configuration changes and add support for the CPU capabilities
change messages sent over the thermal netlink interface by the new
HFI thermal driver to it (Srinivas Pandruvada).
- Convert the DT bindings to yaml format for the Exynos platform and
fix and update the MAINTAINERS file for this driver (Krzysztof
Kozlowski).
- Register the thermal zones as HWmon sensors for the QCom's Tsens
driver and TI thermal platforms (Dmitry Baryshkov, Romain Naour).
- Add the msm8953 compatible documentation in the bindings (Luca
Weiss).
- Add the sm8150 platform support to the QCom LMh driver's DT binding
(Thara Gopinath).
- Check the command result from the IPC command to the BPMP in the
Tegra driver (Mikko Perttunen).
- Silence the error for normal configuration where the interrupt is
optionnal in the Broadcom thermal driver (Florian Fainelli).
- Remove remaining dead code from the TI thermal driver (Yue
Haibing).
- Don't use bitmap_weight() in end_power_clamp() in the powerclamp
driver (Yury Norov).
- Update the OS policy capabilities handshake in the int340x thermal
driver (Srinivas Pandruvada).
- Increase the policies bitmap size in int340x (Srinivas Pandruvada).
- Replace acpi_bus_get_device() with acpi_fetch_acpi_dev() in the

Eric B. has done a bunch obvious (but important) fixes but there's one
a bit controversial: removal of asym_tpm. It was added in 2018 when
TPM1 was already declared as insecure and world had moved on to TPM2.
I don't know how this has passed all the filters but I did not have a
chance to see the patches when they were out. I simply cannot commit
to maintaining this because it was from all angles just wrong to take
it in the first place to the mainline kernel. Nobody should use this
module really for anything.
Finally, there is a new keyring '.machine' to hold MOK keys ('Machine
Owner Keys'). In the mok side MokListTrustedRT UEFI variable can be
set, from which kernel knows that MOK keys are kernel trusted keys and
they are populated to the machine keyring. This keyring linked to the
secondary trusted keyring, which means that can be used like any

kvm/emulate: Fix SETcc emulation function offsets with SLS
The commit in Fixes started adding INT3 after RETs as a mitigation
against straight-line speculation.
The fastop SETcc implementation in kvm's insn emulator uses macro magic
to generate all possible SETcc functions and to jump to them when
emulating the respective instruction.
However, it hardcodes the size and alignment of those functions to 4: a
three-byte SETcc insn and a single-byte RET. BUT, with SLS, there's an
INT3 that gets slapped after the RET, which brings the whole scheme out
of alignment:
15: 0f 90 c0 seto %al
18: c3 ret
19: cc int3
1a: 0f 1f 00 nopl (%rax)
1d: 0f 91 c0 setno %al
20: c3 ret
21: cc int3
22: 0f 1f 00 nopl (%rax)
25: 0f 92 c0 setb %al
28: c3 ret
29: cc int3
and this explodes like this:

perf symbols: Fix symbol size calculation condition
Before this patch, the symbol end address fixup to be called, needed two
conditions being met:
if (prev->end == prev->start && prev->end != curr->start)
Where
"prev->end == prev->start" means that prev is zero-long
(and thus needs a fixup)
and
"prev->end != curr->start" means that fixup hasn't been applied yet
However, this logic is incorrect in the following situation:
*curr = {rb_node = {__rb_parent_color =
278218928,
rb_right = 0x0, rb_left = 0x0},
start = 0xc000000000062354,
end = 0xc000000000062354, namelen = 40, type = 2 '\002',
binding = 0 '\000', idle = 0 '\000', ignore = 0 '\000',
inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
name = 0x1159739e "kprobe_optinsn_page\t[__builtin__kprobes]"}
*prev = {rb_node = {__rb_parent_color =
278219041,
rb_right = 0x109548b0, rb_left = 0x109547c0},
start = 0xc000000000062354,
end = 0xc000000000062354, namelen = 12, type = 2 '\002',
binding = 1 '\001', idle = 0 '\000', ignore = 0 '\000',
inlined = 0 '\000', arch_sym = 0 '\000', annotate2 = false,
name = 0x1095486e "optinsn_slot"}
In this case, prev->start == prev->end == curr->start == curr->end,
thus the condition above thinks that "we need a fixup due to zero
length of prev symbol, but it has been probably done, since the
prev->end == curr->start", which is wrong.
After the patch, the execution path proceeds to arch__symbols__fixup_end
function which fixes up the size of prev symbol by adding page_size to
its end offset.

clocksource: acpi_pm: fix return value of __setup handler
__setup() handlers should return 1 to obsolete_checksetup() in
init/main.c to indicate that the boot option has been handled.
A return of 0 causes the boot option/value to be listed as an Unknown
kernel parameter and added to init's (limited) environment strings.
The __setup() handler interface isn't meant to handle negative return
values -- they are non-zero, so they mean "handled" (like a return
value of 1 does), but that's just a quirk. So return 1 from
parse_pmtmr(). Also print a warning message if kstrtouint() returns

mm: swap: get rid of livelock in swapin readahead
In our testing, a livelock task was found. Through sysrq printing, same
stack was found every time, as follows:
__swap_duplicate+0x58/0x1a0
swapcache_prepare+0x24/0x30
__read_swap_cache_async+0xac/0x220
read_swap_cache_async+0x58/0xa0

do_swap_page+0x374/0x8a0
__handle_mm_fault+0x598/0xd60
handle_mm_fault+0x114/0x200
do_page_fault+0x148/0x4d0
do_translation_fault+0xb0/0xd4
do_mem_abort+0x50/0xb0
The reason for the livelock is that swapcache_prepare() always returns
EEXIST, indicating that SWAP_HAS_CACHE has not been cleared, so that it
cannot jump out of the loop. We suspect that the task that clears the
SWAP_HAS_CACHE flag never gets a chance to run. We try to lower the
priority of the task stuck in a livelock so that the task that clears
the SWAP_HAS_CACHE flag will run. The results show that the system
returns to normal after the priority is lowered.
In our testing, multiple real-time tasks are bound to the same core, and
the task in the livelock is the highest priority task of the core, so
the livelocked task cannot be preempted.
Although cond_resched() is used by __read_swap_cache_async, it is an
empty function in the preemptive system and cannot achieve the purpose
of releasing the CPU. A high-priority task cannot release the CPU
unless preempted by a higher-priority task. But when this task is
already the highest priority task on this core, other tasks will not be
able to be scheduled. So we think we should replace cond_resched() with
schedule_timeout_uninterruptible(1), schedule_timeout_interruptible will
call set_current_state first to set the task state, so the task will be
removed from the running queue, so as to achieve the purpose of giving
up the CPU and prevent it from running in kernel mode for too long.
(akpm: ugly hack becomes uglier. But it fixes the issue in a
backportable-to-stable fashion while we hopefully work on something
better)

iavf: Fix hang during reboot/shutdown
Recent commit
974578017fc1 ("iavf: Add waiting so the port is
initialized in remove") adds a wait-loop at the beginning of
iavf_remove() to ensure that port initialization is finished
prior unregistering net device. This causes a regression
in reboot/shutdown scenario because in this case callback
iavf_shutdown() is called and this callback detaches the device,
makes it down if it is running and sets its state to __IAVF_REMOVE.
Later shutdown callback of associated PF driver (e.g. ice_shutdown)
is called. That callback calls among other things sriov_disable()
that calls indirectly iavf_remove() (see stack trace below).
As the adapter state is already __IAVF_REMOVE then the mentioned
loop is end-less and shutdown process hangs.
The patch fixes this by checking adapter's state at the beginning
of iavf_remove() and skips the rest of the function if the adapter
is already in remove state (shutdown is in progress).
Reproducer:
1. Create VF on PF driven by ice or i40e driver
2. Ensure that the VF is bound to iavf driver
3. Reboot

net: mscc: ocelot: fix backwards compatibility with single-chain tc-flower offload
ACL rules can be offloaded to VCAP IS2 either through chain 0, or, since
the blamed commit, through a chain index whose number encodes a specific
PAG (Policy Action Group) and lookup number.
The chain number is translated through ocelot_chain_to_pag() into a PAG,
and through ocelot_chain_to_lookup() into a lookup number.
The problem with the blamed commit is that the above 2 functions don't
have special treatment for chain 0. So ocelot_chain_to_pag(0) returns
filter->pag = 224, which is in fact -32, but the "pag" field is an u8.
So we end up programming the hardware with VCAP IS2 entries having a PAG
of 224. But the way in which the PAG works is that it defines a subset
of VCAP IS2 filters which should match on a packet. The default PAG is
0, and previous VCAP IS1 rules (which we offload using 'goto') can
modify it. So basically, we are installing filters with a PAG on which
no packet will ever match. This is the hardware equivalent of adding
filters to a chain which has no 'goto' to it.
Restore the previous functionality by making ACL filters offloaded to
chain 0 go to PAG 0 and lookup number 0. The choice of PAG is clearly
correct, but the choice of lookup number isn't "as before" (which was to
leave the lookup a "don't care"). However, lookup 0 should be fine,
since even though there are ACL actions (policers) which have a
requirement to be used in a specific lookup, that lookup is 0.

This patch fixes this issue by -
1. Removing request_firmware() logic from the probe()
such that .ndo_open() handle it as it used to handle
it earlier
2. Given request_firmware() is removed from probe(), so
driver has to relax FW version comparisons a bit against
the already loaded FW version (by some other PFs of same
adapter) to allow different compatible/close enough FWs with which
multiple PFs may run with (in different environments), as the
given PF who is in probe flow has no idea now with which firmware
file version it is going to initialize the device in ndo_open()

ACPI: video: Force backlight native for Clevo NL5xRU and NL5xNU
Clevo NL5xRU and NL5xNU/TUXEDO Aura 15 Gen1 and Gen2 have both a working
native and video interface. However the default detection mechanism first
registers the video interface before unregistering it again and switching
to the native interface during boot. This results in a dangling SBIOS
request for backlight change for some reason, causing the backlight to
switch to ~2% once per boot on the first power cord connect or disconnect
event. Setting the native interface explicitly circumvents this buggy
behaviour by avoiding the unregistering process.

Revert "arm64: dts: freescale: Fix 'interrupt-map' parent address cells"
This reverts commit
869f0ec048dc8fd88c0b2003373bd985795179fb. That
updated the expected device tree binding format for the ls-extirq
driver, without also updating the parsing code (ls_extirq_parse_map)
to the new format.
The context is that the ls-extirq driver uses the standard
"interrupt-map" OF property in a non-standard way, as suggested by
Rob Herring during review:
https://lore.kernel.org/lkml/
20190927161118.GA19333@bogus/
This has turned out to be problematic, as Marc Zyngier discovered
through commit
041284181226 ("of/irq: Allow matching of an interrupt-map
local to an interrupt controller"), later fixed through commit
de4adddcbcc2 ("of/irq: Add a quirk for controllers with their own
definition of interrupt-map"). Marc's position, expressed on multiple
opportunities, is that:
(a) [ making private use of the reserved "interrupt-map" name in a
driver ] "is wrong, by the very letter of what an interrupt-map
means. If the interrupt map points to an interrupt controller,
that's the target for the interrupt."
https://lore.kernel.org/lkml/87k0g8jlmg.wl-maz@kernel.org/
(b) [ updating the driver's bindings to accept a non-reserved name for
this property, as an alternative, is ] "is totally pointless. These
machines have been in the wild for years, and existing DTs will be
there *forever*."
https://lore.kernel.org/lkml/87ilvrk1r0.wl-maz@kernel.org/
Considering the above, the Linux kernel has quirks in place to deal with
the ls-extirq's non-standard use of the "interrupt-map". These quirks
may be needed in other operating systems that consume this device tree,
yet this is seen as the only viable solution.
Therefore, the premise of the patch being reverted here is invalid.
It doesn't matter whether the driver, in its non-standard use of the
property, complies to the standard format or not, since this property
isn't expected to be used for interrupt translation by the core.
This change restores LS1088A, LS2088A/LS2085A and LX2160A to their
previous bindings, which allows these systems to continue to use
external interrupt lines with the correct polarity.

thermal: int340x: Update OS policy capability handshake
Update the firmware with OS supported policies mask, so that firmware can
relinquish its internal controls. Without this update several Tiger Lake
laptops gets performance limited with in few seconds of executing in
turbo region.
The existing way of enumerating firmware policies via IDSP method and
selecting policy by directly writing those policy UUIDS via _OSC method
is not supported in newer generation of hardware.
There is a new UUID "
B23BA85D-C8B7-3542-88DE-
8DE2FFCFD698" is defined for
updating policy capabilities. As part of ACPI _OSC method:
Arg0 - UUID:
B23BA85D-C8B7-3542-88DE-
8DE2FFCFD698
Arg1 - Rev ID: 1
Arg2 - Count: 2
Arg3 - Capability buffers: Array of Arg2 DWORDS
DWORD1: As defined in the ACPI 5.0 Specification
- Bit 0: Query Flag
- Bits 1-3: Always 0
- Bits 4-31: Reserved
DWORD2 and beyond:
- Bit0: set to 1 to indicate Intel(R) Dynamic Tuning is active, 0 to
indicate it is disabled and legacy thermal mechanism should
be enabled.
- Bit1: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
active cooling, 0 to indicate bios shall enable legacy thermal
zone with active trip point.
- Bit2: set to 1 to indicate Intel(R) Dynamic Tuning is controlling
passive cooling, 0 to indicate bios shall enable legacy thermal
zone with passive trip point.
- Bit3: set to 1 to indicate Intel(R) Dynamic Tuning is handling
critical trip point, 0 to indicate bios shall enable legacy
thermal zone with critical trip point.
- Bits 4:31: Reserved
From sysfs interface, there is an existing interface to update policy
UUID using attribute "current_uuid". User space can write the same UUID
for ACTIVE, PASSIVE and CRITICAL policy. Driver converts these UUIDs to
DWORD2 Bit 1 to Bit 3. When any of the policy is activated by user
space it is assumed that dynamic tuning is active.
For example
$cd /sys/bus/platform/devices/INTC1040:00/uuids
To support active policy
$echo "
3A95C389-E4B8-4629-A526-
C52C88626BAE" > current_uuid
To support passive policy
$echo "
42A441D6-AE6A-462b-A84B-
4A8CE79027D3" > current_uuid
To support critical policy
$echo "
97C68AE7-15FA-499c-B8C9-
5DA81D606E0A" > current_uuid
To check all the supported policies
$cat current_uuid
3A95C389-E4B8-4629-A526-
C52C88626BAE
42A441D6-AE6A-462b-A84B-
4A8CE79027D3
97C68AE7-15FA-499c-B8C9-
5DA81D606E0A
To match the bit format for DWORD2, rearranged enum int3400_thermal_uuid
and int3400_thermal_uuids[] by swapping current INT3400_THERMAL_ACTIVE
and INT3400_THERMAL_PASSIVE_1.
If the policies are enumerated via IDSP method then legacy method is
used, if not the new method is used to update policy support.

cpufreq: intel_pstate: Use firmware default EPP
For some specific platforms (E.g. AlderLake) the balance performance
EPP is updated from the hard coded value in the driver. This acts as
the default and balance_performance EPP. The purpose of this EPP
update is to reach maximum 1 core turbo frequency (when possible) out
of the box.
Although we can achieve the objective by using hard coded value in the
driver, there can be other EPP which can be better in terms of power.
But that will be very subjective based on platform and use cases.
This is not practical to have a per platform specific default hard coded
in the driver.
If a platform wants to specify default EPP, it can be set in the firmware.
If this EPP is not the chipset default of 0x80 (balance_perf_epp unless
driver changed it) and more performance oriented but not 0, the driver
can use this as the default and balanced_perf EPP. In this case no driver
update is required every time there is some new platform and default EPP.
If the firmware didn't update the EPP from the chipset default then
the hard coded value is used as per existing implementation.
