In the current implementation, once dynamic fps update
kicks in, MDSS driver enables DSI timing db property.
But from chipsets like sdm660, DSI_CMD_OFFSET and
DSI_CMD_LENGTH register has become double buffered and
since timing db property was enabled as part of dynamic
fps update, DSI commands transfer for backlight update,
panel health check or panel off might fail if there is
no control flush. So disable DSI timing db property once
dynamic fps update sequence is complete.

The driver uses the bus_request platform operation to
request resources from the platform for a specific bandwidth.
Currently the driver requests resources for the maximum
theoretical bandwidth, when interface is brought up.
Refine this process a bit: now the driver will request a
small amount of resources when interface is up, and will only
issue the maximum request when connected.
This mechanism will be improved further in the future to make
more refined requests based on actual bandwidth.

There is race between page freeing and unreserved highatomic.
CPU 0 CPU 1

set_pcppage_migratetype(page, mt)
unreserve_highatomic_pageblock

spin_unlock_irqrestore(&zone->lock)
free_pcppages_bulk
__free_one_page(mt) <- mt is stale
By above race, a page on CPU 0 could go non-highorderatomic free list
since the pageblock's type is changed. By that, unreserve logic of
highorderatomic can decrease reserved count on a same pageblock severak
times and then it will make mismatch between nr_reserved_highatomic and
the number of reserved pageblock.
So, this patch verifies whether the pageblock is highatomic or not and
decrease the count only if the pageblock is highatomic.

Patch series "use up highorder free pages before OOM", v3.
I got OOM report from production team with v4.4 kernel. It had enough
free memory but failed to allocate GFP_KERNEL order-0 page and finally
encountered OOM kill. It occured during QA process which launches
several apps, switching and so on. It happned rarely. IOW, In normal
situation, it was not a problem but if we are unluck so that several
apps uses peak memory at the same time, it can happen. If we manage to
pass the phase, the system can go working well.
I could reproduce it with my test(memory spike easily. Look at below.
The reason is free pages(19M) of DMA32 zone are reserved for
HIGHORDERATOMIC and doesn't unreserved before the OOM.

During the investigation, I found some problems with highatomic so this
patch aims to solve the problems and the final goal is to unreserve
every highatomic free pages before the OOM kill.
This patch (of 4):
In page freeing path, migratetype is racy so that a highorderatomic page
could free into non-highorderatomic free list. If that page is
allocated, VM can change the pageblock from higorderatomic to something.
In that case, highatomic pageblock accounting is broken so it doesn't
work(e.g., VM cannot reserve highorderatomic pageblocks any more
although it doesn't reach 1% limit).
So, this patch prohibits the changing from highatomic to other type.
It's no problem because MIGRATE_HIGHATOMIC is not listed in fallback
array so stealing will only happen due to unexpected races which is
really rare. Also, such prohibiting keeps highatomic pageblock more
longer so it would be better for highorderatomic page allocation.
