With this patch, anon pages of inactive tasks can be reclaimed,
depending on memory pressure. Memory pressure is detected
using vmpressure events. 'N' best tasks in terms of anon
size is selected and pages proportional to their tasksize
is reclaimed. The total number of pages reclaimed at each
run of the swap work, can be tuned from userspace, the
default being SWAP_CLUSTER_MAX * 32.
The patch also adds tracepoints to debug and tune the
feature.
echo 1 > /sys/module/process_reclaim/parameters/enable_process_reclaim
to enable the feature.
echo <pages> > /sys/module/process_reclaim/parameters/per_swap_size,
to set the number of pages reclaimed in each scan.
/sys/module/process_reclaim/parameters/reclaim_avg_efficiency, provides
the average efficiency (scan to reclaim ratio) of the algorithm.
/sys/module/process_reclaim/parameters/swap_eff_win, to set the window
period (in unit of number of times reclaim is triggered) to detect
low efficiency runs.
/sys/module/process_reclaim/parameters/swap_opt_eff, to set the optimal
efficiency threshold for low efficiency detection.

The GPU clocks on msm8996 have three dedicated PLLs, MMPLL2,
MMPLL8, and MMPLL9. We leave MMPLL9 at the maximum speed (624
MHz), and we use MMPLL2 and MMPLL8 for the other frequencies. To
make switching frequencies faster, we ping-pong between MMPLL2
and MMPLL8 when we're switching between frequencies that aren't
the maximum. Implement custom rcg clk ops for this type of
frequency switching.

Some gdsc power domains can have a gds_hw_controller block inside
to help ensure all slave devices within the power domain are idle
before the gdsc is actually switched off.
This is mainly useful in power domains which host a MMU, in which
case its necessary to make sure there are no outstanding MMU operations
or pending bus transactions before the power domain is turned off.
In gdscs with gds_hw_controller block, its necessary to check the
gds_hw_ctrl status bits instead of the ones in gdscr, to determine
the state of the powerdomain.
While at it, also move away from using jiffies and use ktime APIs
instead for busy looping on status bits.

A recent change to regulator framework replaced the
regulator_set_optimum_mode API with regulator_set_load.
The regulator_set_load API does the following for regulators which have
not implemented set_load().
- determines the most optimal mode for the given load by calling
get_optimum_mode()
- gets the current mode by calling get_mode()
- calls set_mode() if the modes are different and expects the mode to be
committed to the hardware
The rpm-smd-regulator's get_optimum_mode() remembers the load and uses that
for the upcoming get_mode() call. This causes the framework to never call
the set_mode API, thereby causing rpm-smd-regulator to never send the load
to the RPM.
The set_load op was introduced for hardware which does not support the
set_mode op. This is convenient since the RPM sets the mode according to
the aggregated load requirements. In addition the RPM also supports forcing
certain modes which fits well with the set_mode op.
Implement the set_load op to send the aggregated load vote to RPM, and
repurpose the set_mode op to send the aggregated mode vote to RPM.
Remove the get_optimum_mode op since it is no longer required with this
change.
Repurposing of set_mode should not impact consumers since it has the same
effect as before. Instead of sending a load vote which would cause the RPM
to select the desired mode the mode will be sent directly.
Furthermore, the hpm-min-load device tree property is no longer required
since the mode is no longer set based on the hpm-min-load threshold.
Remove it.

When cluster enters a low power mode, the mode entered is stored
in last_level. During LPM driver probe last_level is initialized
to default level, if a core in that cluster is online.
If all the cores in the cluster are hotplugged after initializing
the last_level and before the per cluster data structures are
initialized, cluster enters low power mode but does not update
last_level as the data structures are not available. In this case
when a core in this cluster is coming online and last_level indicates
default level, assumes cluster did not enter any low power mode,
the update of flags to reflect the cores as active for this cluster
does not happen. This makes driver to select system level low power
mode as if this cluster is in low power mode eventhough it is out
of low power mode.
To avoid this race, prevent cores hotplug during lpm probe.
