fs: add F2FS support
Remove temporary workaround for Novathor Settings
USB: full port from STEXperia Sola kernel
Add LZ4 support
Enable UHID (XperiaSTE Sola repo)
mm: Don't wait for congestion when mem is high This
 fixes a huge IOWAIT issue when memory usage is
 high. Credits to Oppo
Enable CD-ROM/DVD Filesystems support
mm: SLQB memory allocator

Since Mali OSK memory allocation failure has been fixed.
I would like to give SLQB which Ezekeel always uses a try.
UHID: add missing files
F2FS: add missing files
defconfig: add SLQB memory allocator
block: Switch from BFQ-v7r3 for 3.0.0 to BFQ-v7r4 for 3.0.0

. BUGFIX. Modified the code so as to be robust against late detection of
  NCQ support for a rotational device.
. BUGFIX. Removed a bug that hindered the correct throughput distribution
  on flash-based devices when not every process had to receive the same
  fraction of the throughput. This fix entailed also a little efficiency
  improvement, because it implied the removal of a short function executed
  in a hot path.
. CODESTYLE IMPROVEMENT: removed quoted strings split across lines.

block: Switch from BFQ-v7r4 for 3.0.0 to BFQ-v7r5 for 3.0.0

. IMPROVEMENT: Improve throughput boosting by idling the device
  only for processes that, in addition to perform sequential I/O,
  are I/O-bound (apart from weight-raised queues, for which idling
  is always performed to guarantee them a low latency).
. IMPROVEMENT: Improve throughput boosting by depriving processes
  that cooperate often of weight-raising.
. CODE IMPROVEMENT: Pass of improvement of the readability of both
  comments and actual code.
