-> makefile: refresh toolchain arm-cortex_a15-linux-gnueabihf-linaro_4.9.3-2014.11 
-> blu_active: Remove input and sync freq logic, Check actual freq before set new freq, Exercise hispeed settings at a policy level 
-> CAF audio subsystem updates (too much commits, check git) 
-> FS: import F2FS, Update F2FS 
-> block/partitions: optimize memory allocation in check_partition() 
-> mm/page-writeback.c: fix dirty_balance_reserve subtraction from dirtyable memory 
-> mm: fix calculation of dirtyable memory 
-> mm: vmscan: If kswapd has been running too long, allow it to sleep 
-> mm, vmalloc: remove useless variable in vmap_block, use well-defined find_last_bit() func 
-> CPU hotplug, writeback: Don't call writeback_set_ratelimit() too often during hotplug 
-> writeback: increase bdi_min_ratio to 5 in light of the latest writeback commit. 
-> CPU hotplug, debug: detect imbalance between get_online_cpus() and put_online_cpus() 
-> binfmt_elf.c: use get_random_int() to fix entropy depleting 
-> stop_machine: Use smpboot threads, Store task reference in a separate per cpu variable, Mark per cpu stopper enabled early 
-> kthread: Prevent unpark race which puts threads on the wrong cpu, Implement park/unpark facility 
-> kthread_worker: reimplement flush_kthread_work() to allow freeing the work item being executed, reorganize to prepare for flush_kthread_work() reimplementation 
-> smpboot: Allow selfparking per cpu threads, Provide infrastructure for percpu hotplug threads 
-> smpboot, idle: Fix comment mismatch over idle_threads_init(), Optimize calls to smp_processor_id() in idle_threads_init() 
-> hotplug: Fix UP bug in smpboot hotplug code 
-> smp, idle: Allocate idle thread for each possible cpu during boot 
-> smp: Add generic smpboot facility, Provide generic idle thread allocation 
-> cpufreq: cpu-boost: Add cpu-boost driver, Use hotplug thread infrastructure, upstream CAF updates, small fixes 
-> defconfig: sync with CM12, Enable generic idle threads 
-> OTG USB flash drives automount support FAT32 (for ExFAT and NTFS use stickmount) 
-> RAMdisk tweaks and fixes, sync with CM12
