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
reclaim pages in (0x100000 - 0x102000)

Some pages could be shared by several processes. (ex, libc)
In case of that, it's too bad to reclaim them from the beginnig.
This patch causes VM to keep them on memory until last task
try to reclaim them so shared pages will be reclaimed only if
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.

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.

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.

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.
