The previous patch added the NETIF_F_GRO_FRAGLIST feature.
This is a software feature that should default to off.
Current software features default to on, so add a new
feature set that defaults to off.

Commit 7d3ecfd796 ("input: qcom-hv-haptics: read CAL_TLRA_CL_STS from
SDAM after boot up") added support for LRA frequency calibration.
However, since bootloader changes needed to support this feature had
caused a regression on devices that has PM8350B v1 PMIC, this got
reverted with commit 844516d943 ("Revert "input: qcom-hv-haptics: read
CAL_TLRA_CL_STS from SDAM after boot up""). Now that the bootloader
changes handles PM8350B v1 configuration properly, re-enable this
change.
During LRA frequency calibration, reading CAL_TLRA_CL_STS has to be
done before de-asserting play. In the boot up LRA frequency calibration
sequence, CAL_TLRA_CL_STS was read out and stored in SDAM module
registers by the bootloader. Later, HLOS haptics driver can read it from
there and use it for calculating LRA frequency. This boot up LRA
frequency calibration sequence is only available for PM8350B 2.0 chip.
Update the driver to support this.

Without the change, the memory shared with the external

The primary virtual machine(PVM) lends resources such
as IO memory and touch irq to TVM prior to trusted touch
is initiated and reclaims those resources back after trusted
touch usecase finishes.The resource requirements of TVM
such as clock, regulators etc are taken care by PVM.

During any sensor threshold notification, the of-thermal framework
checks whether any trip of each thermal zone for that sensor is
violated or not. It requests thermal zone re-evaluation only for
those thermal zones those trip is violated. If trips are violated
for none of thermal zones due to some reason, then of-thermal ignores
that sensor notification and it leads to no active trip threshold
for that sensor forever.
Notify and request thermal zone re-evaluation for at least one thermal
zone for that sensor if trips are violated for none in of-thermal.
It makes sure that for every sensor notification, thermal zone
aggregate and set next active trip.

Upstream commit f0fe00d4972a8cd4b98cc2c29758615e4d51cdfe.
In addition to -ftrivial-auto-var-init=pattern (used by
CONFIG_INIT_STACK_ALL now) Clang also supports zero initialization for
locals enabled by -ftrivial-auto-var-init=zero. The future of this flag
is still being debated (see https://bugs.llvm.org/show_bug.cgi?id=45497).
Right now it is guarded by another flag,
-enable-trivial-auto-var-init-zero-knowing-it-will-be-removed-from-clang,
which means it may not be supported by future Clang releases. Another
possible resolution is that -ftrivial-auto-var-init=zero will persist
(as certain users have already started depending on it), but the name
of the guard flag will change.
In the meantime, zero initialization has proven itself as a good
production mitigation measure against uninitialized locals. Unlike pattern
initialization, which has a higher chance of triggering existing bugs,
zero initialization provides safe defaults for strings, pointers, indexes,
and sizes. On the other hand, pattern initialization remains safer for
return values. Chrome OS and Android are moving to using zero
initialization for production builds.
Performance-wise, the difference between pattern and zero initialization
is usually negligible, although the generated code for zero
initialization is more compact.
This patch renames CONFIG_INIT_STACK_ALL to CONFIG_INIT_STACK_ALL_PATTERN
and introduces another config option, CONFIG_INIT_STACK_ALL_ZERO, that
enables zero initialization for locals if the corresponding flags are
supported by Clang.

Commit 323ebb61e3 ("net: use listified RX for handling GRO_NORMAL
skbs") made use of listified skb processing for the users of
napi_gro_frags().
The same technique can be used in a way more common napi_gro_receive()
to speed up non-merged (GRO_NORMAL) skbs for a wide range of drivers
including gro_cells and mac80211 users.
This slightly changes the return value in cases where skb is being
dropped by the core stack, but it seems to have no impact on related
drivers' functionality.
gro_normal_batch is left untouched as it's very individual for every
single system configuration and might be tuned in manual order to
achieve an optimal performance.
