Commit 602c233f65 added a conditional for
ops->get_trip_temp(). In the original code,
ops->get_trip_temp() is called unconditionally. So delete
the conditional to fix it. At the same time, modify the
comment of enable. Actually, IPA is always enable, but
sometimes it needs to be disabled for a while. Making
'enable' true or false, IPA can be enabled or disabled by
user requirement.
When the 'override' turns to false from true and current
temperature is below the switch_on_temp(means 'update' is
false), the cooling device state has not changed, also
the power could not be updated to the maximum power. So
add a vendor hook to renew the 'update' value, so that the
cooling device can be updated.

Add vendor hooks to disable randomization of swap slot allocation for
swap partition used for saving hibernation image. Another level of
randomization of swap slots takes place at the firmware level as well
in order to address the wear leveling for UFS/MMC devices, so this
vendor hook checks if a block device represents the swap partition being
used for saving hibernation image, if yes, the swap slot allocation for
such partition is serialized at kernel level.
There is a performance advantage of reading contiguous pages of hibernation
image, it makes the restore logic of hibernation image simpler and faster
as there are no seeks involved in the secondary storage to read multiple
contiguous pages of the image.

Currently the core UFS driver does not have a vops to notify when the
device is operational. This commit introduces a hook, which serves to
notify device completing initialization and is ready to accept I/O.
This is required by the FIPS140-2 [1] self integrity test of inline
encryption engine, which must run whenever the host controller is reset.
The code requires sleeping while waiting for I/O to complete and allocating
some memory dynamically, which requires the vendor hook to be restricted.

There were 3 remaining types directly referenced by vendor
hooks that were not fully-defined in the KMI:
struct blk_mq_alloc_data : defined in block/blk-mq.h
struct readahead_control ; defined include/linux/pagemap.h
struct selinux_state : defined in security/selinux/include/security.h
libabigail is not finding definitions based on the instantiation
of the hooks, so force them to be defined by defining dummy exported
symbols. Since blk_mq_alloc_data and selinux_state are defined in
subsystem-private headers, create new vendor_hooks.c files in

With this change, 46 types that were unknown in the previous

Of the 96 remaining opaque types, 43 are defined in C files, so

To avoid changing the visibiliy of data types when including
hook definition headers remove header file inclusions from
the hook definition header files.
Instead, the hook definition headers should just have forward
declarations that don't require full definition.
To provide full definitions of the types for the KMI, the
headers that define the types should be included by the
source file that instantiates the hooks - normally
vendor_hooks.c.
Since the KMI is frozen, some of the inclusions are still
required to preserve the CRC associated with symbols. Keep
these inclusions under #ifdef __GENKSYMS__.

Change how vendor hooks are instantiated to promote
more complete structure definition in the ABI XML
description without complicating hook definition for
partners.
We don't want to force partners to include all
headers as part of the hook definition in include/trace/hooks/
since that causes extra headers to be included in
source files that runs the risk of changing visibility
resulting in CRC changes to KMI symbols. Instead continue
the practice of using forward declarations in the hook
header files.
Instead of instantiating hook tracepoints globally in
drivers/android/vendor_hooks.c, use subsystem-specific
vendor_hooks.c. This avoids namespace collisions between
internal header files and limits the exposure to the internal
headers to the instantiation, not the call sites.
In this patch, all of the scheduler related hooks are
instantiated in kernel/sched/vendor_hooks.c which can
cleanly include scheduler-related header files to
provide full type visibility.
Since this is being done on a KMI frozen branch, there
are some __GENKSYMS__ tricks needed to preserve the
existing CRC as we increase the number of fully typed
structs. These tricks won't be needed when this is
introduced on a non-KMI-frozen branch.
With this patch, the number of undefined types was
reduced from 108 to 68.

We recently noticed an issue where freezing of user space tasks is
failed due to a process being in uninterruptible sleep state.
Currently, the logging of unfrozen tasks is disabled by default.
Although it can be enabled for debugging via a adb command, it's
usually hard to reproduce the issue. So we want to add a vendor hook
to log unfrozen tasks.
pm_debug_messages enables a large amount of log output during every
suspend/resume cycle of which at most 1 line is helpful for
investigating this recurring class of battery life issues. Deploying
builds with pm_debug_messages is therefore not viable, as it
substantially shortens the temporal span of the log. The new vendor
hook will only emit logs specific to this class of problem, and only
when the problem actually manifests.
