Got an old unused zenfone 5 from my brother and I've compiled this kernel because i'm not satisfy with some of the available kernel so far. Nothing fancy, just a (hopefully) stable kernel for stock lollipop or custom rom based on stock lollipop.
Features:

Like i said, nothing fancy lol. Things that i've modified/added:
- Updated interactive cpu governor and fine tuned its parameters.
- Enabled conservative cpu governor and disabled userspace cpu governor.
- Added zendecision cpu hotplug helper.
- Updated cfs scheduler.
- Added bfq disk io scheduler and made it as default on booting.
- Enabled all tcp congestion control and made westwood as default on booting.
- Added power efficient workque support. Should help with battery life.
- Added quick wakeup driver support. Should help with battery life.
- Added async fsync support. Should help with battery life and perfomance.
- Enabled joystick game controller support.
- Enabled usb serial driver support.
- Enabled zram driver support and made it use 256mb on booting. Should help with perfomance.
- Enabled powerclamp and rapl driver for intel thermal daemon support. Should help minimize heat.
- Enabled ntfs driver with read/write support.
- Enabled cifs and smb network drive driver support.
- Added exfat-nofuse filesystem driver support with proper automount on booting.
- Enabled zenmotion dt2w support.
- Made selinux mode as permissive on boot. This fixed the dreaded signal loss issue.
- Added proper init.d support in ramdisk, with proper permission setup before running scripts.
- Probably many, many other things i forgot to list here...
