ASoC: msm: qdsp6v2: fix non-gapless transition failure
During non-gapless transition, there is an indefinite wait in
drain until either eos_ack or cmd_interrupt is set. This results
in playback getting stuck and occurs because cmd_interrupt is
not set in TRIGGER_STOP as gapless_transition is set to 1 during
partial drain of earlier stream.
Fix the issue by setting gapless_transition to 0 when gapless
fails which ensures that cmd_interrupt is set in TRIGGER_STOP.

regulator: rpm-smd-regulator: implement set_load
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.

lpm_levels: Avoid race by preventing hotplug during lpm probe
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.

mm, sl[au]b: add __GFP_ATOMIC to the GFP reclaim mask
Commit
d0164adc89f6 ("mm, page_alloc: distinguish between being unable to
sleep, unwilling to sleep and avoiding waking kswapd") modified __GFP_WAIT
to explicitly identify the difference between atomic callers and those
that were unwilling to sleep. Later the definition was removed entirely.
The GFP_RECLAIM_MASK is the set of flags that affect watermark checking
and reclaim behaviour but __GFP_ATOMIC was never added. Without it, atomic
users of the slab allocator strip the __GFP_ATOMIC flag and cannot access
the page allocator atomic reserves. This patch addresses the problem.
The user-visible impact depends on the workload but potentially atomic
allocations unnecessarily fail without this path.

mm: Support address range reclaim
This patch adds address range reclaim of a process.
The requirement is following as,
Like webkit1, it uses a address space for handling multi tabs.
IOW, it uses *one* process model so all tabs shares address space
of the process. In such scenario, per-process reclaim is rather
coarse-grained so this patch supports more fine-grained reclaim
for being able to reclaim target address range of the process.
For reclaim target range, you should use following format.
echo [addr] [size-byte] > /proc/pid/reclaim
The addr should be page-aligned.
So now reclaim konb's interface is following as.
echo file > /proc/pid/reclaim
reclaim file-backed pages only
echo anon > /proc/pid/reclaim
reclaim anonymous pages only
echo all > /proc/pid/reclaim
reclaim all pages
echo 0x100000 8K > /proc/pid/reclaim

all of task has gone swapping out.
This feature doesn't handle non-linear mapping on ramfs because
it's very time-consuming and doesn't make sure of reclaiming and
not common.

mm: Per process reclaim
These day, there are many platforms avaiable in the embedded market
and they are smarter than kernel which has very limited information
about working set so they want to involve memory management more heavily
like android's lowmemory killer and ashmem or recent many lowmemory
notifier.
One of the simple imagine scenario about userspace's intelligence is that
platform can manage tasks as forground and backgroud so it would be
better to reclaim background's task pages for end-user's *responsibility*
although it has frequent referenced pages.
This patch adds new knob "reclaim under proc/<pid>/" so task manager
can reclaim any target process anytime, anywhere. It could give another
method to platform for using memory efficiently.
It can avoid process killing for getting free memory, which was really
terrible experience because I lost my best score of game I had ever
after I switch the phone call while I enjoyed the game.
Reclaim file-backed pages only.
echo file > /proc/PID/reclaim
Reclaim anonymous pages only.
echo anon > /proc/PID/reclaim
Reclaim all pages
echo all > /proc/PID/reclaim

mm: prevent to write out dirty page in CMA by may_writepage
Now, local variable references in shrink_page_list is
PAGEREF_RECLAIM_CLEAN as default. It is for preventing to reclaim
dirty pages when CMA try to migrate pages.
Strictly speaking, we don't need it because CMA already didn't allow
to write out by .may_writepage = 0 in reclaim_clean_pages_from_list.
Morever, it has a problem to prevent anonymous pages's swap out when
we use force_reclaim = true in shrink_page_list(ex, per process reclaim
can do it)
So this patch makes references's default value to PAGEREF_RECLAIM
and declare .may_writepage = 0 of scan_control in CMA part to make
code more clear.

qcom-charger: introduce parallel charging support
Parallel charging increases charging capacity and efficiency by
distributing the current between two charging chips.
PMI8998 feeds the parallel charger via its MID input, and handles
input current limiting in its front-porch FET. As master charger,
PMI8998 is responsible for enabling/disabling the parallel
charger, and the FCC distribution.
To enable parallel charging in software, the following conditions
must be met:
- Strong USBIN input
- Battery present
- In fast or taper charging state
- Attached UFP source
While the enabling/disabling is always under the control of software
the disabling can also be done by hardware in case of fault.
Battery current is usually fixed to the battery rating. The FCC
distribution is simple, a split of 50/50 by default, which can
be changed in runtime.
When taper irq kicks in, the algorithm reduces parallel FCC by 25%.
This puts the charging back in constant current phase until the
next one happens where again the algorithm reduces the FCC by
25%. This continues until the parallel FCC drops to 500mA. At that
time parallel charging is disabled and master continues charging
the rest of constant voltage phase.
