When a system is entering RPM assisted sleep, the NOACK messages are
not accounted in preventing such sleep modes as no driver is waiting
on it. In such scenarios, some active messages could still be in the
Apps RX buffer which reduces the number of outstanding sleep messages.
Fix by accounting for NOACK messages while flushing sleep set requests
and ensuring that they are read before sending any sleep set requests.
The original changes were reverted to address issues with SMD transport.
This change includes fixes from earlier squashed into a single commit.

This deliberately changes the behavior of the per-cpuset
cpus file to not be effected by hotplug. When a cpu is offlined,
it will be removed from the cpuset/cpus file. When a cpu is onlined,
if the cpuset originally requested that that cpu was part of the cpuset, that
cpu will be restored to the cpuset. The cpus files still
have to be hierachical, but the ranges no longer have to be out of
the currently online cpus, just the physically present cpus.

ability to be updated instantly whenever the panel is fetching

Once enabled, lineptr can only be disabled when 0 is written to the node

qseecom_send_modfd_cmd converts ION buffer's virtual address to
scatter gather(SG) list and then sends them to TA by populating
SG list into message buffer. As the physical memory address in
SG list is used directly by TA, this allows a malicious TA to
access/corrupt arbitrary physical memory and may lead to the
process gaining kernel/root privileges. Thus, make changes to
have the QSEEComm driver passing a list of whitelist buffers
that is allowed to be mapped by TA, and the QSEE kernel, in turn,
should add checks to the register_shared_buffer syscall to make
sure the shared buffers an application is mapping falls within
one of these whitelist buffers.

Commit 85635da429 ("qcom-charger: smb138x: fix buck damage on

in the struct. However there are implict assumptions in the driver that
the first member is the library structure. This causes memory corruption
and an eventual watch dog bite reset.
Fix it by ensuring that the library struct is explicitly initialized
from the parent struct.

sysctl_sched_wake_to_idle is a means to allow or disallow a global
task placement preference for idle CPUs. It has been unused thus
far since we've preferred to use a per-task flag instead to control
placement for individual tasks. Using this global flag, however, does
allow greater flexibility for testing and system evaluation.

Do the aggregation for frequency only when the total group busy time
is above sched_freq_aggregate_threshold. This filtering is especially
needed for the cases where groups are created by including all threads
of an application process. This knob can be tuned to apply aggregation
only for the heavy workload applications.
When this knob is enabled and load is aggregated, the load is not
clipped to 100% @ current frequency to ramp up the frequency faster.

The load reporting during frequency alert notifications is broken under
load aggregation. When aggregation is enabled, the total group busy
time is accounted towards the maximum busy CPU of a frequency domain.
If this CPU has a notification pending, it's group busy time alone is
accounted and other CPU's group busy time is completely ignored.
Similarly if any CPU other than maximum busy CPU has a pending
notification, its group busy time is accounted twice.
Maintain the frequency alert notification flag per frequency domain.
When the notification is pending, don't clip the load to 100% @ fur
for any of the CPUs in the frequency domain.

notify_migration() is a HMP specific function that relies on all
of its contents to be stubbed out for !CONFIG_SCHED_HMP. However,
it still maintains calls to rcu_read_lock/unlock(). In the !HMP
case these calls are simply redundant. Move the function under
CONFIG_SCHED_HMP and add a stub when the config is not defined so
that there is no overhead.

Most code pertaining to CONFIG_SCHED_HMP has been moved to a separate
file "hmp.c" in order to facilitate kernel upgrades. Fewer changes in
the original scheduler files means fewer conflicts. Some parts of code,
however, could not be moved to the separate file either because of
dependencies with other non-HMP code or because the changes are specific
only to the scheduling classes where the code resides.
