Device Specific Changes:
- Etude kernel: Op.11 No.5
* Linux 4.9.286
* merged CAF tag LA.UM.9.8.r1-04000-SDM710.0 with fix on cdsp regression
* DO NOT use a third party kernel without proper support for Pixel thermal hal
- Fixed the smoothness of brightness transitions
* brightness now changes in the smallest steps possible, so lower brightness range adjustment no longer feels choppy
* the effect is similar to the hack at the end of android10, but the implementation is much better
- Improved the double click haptic feedback to actually feel like a double click
* you can try it by putting a wrong finger on the fingerprint sensor
- Added the missing libvpphcp.so
- Tweaked the default thermal profile to hotplug two big CPU cores when the device is really hot
* in terms of thermal mitigation, offlining two CPU cores is a lot more effective than throttling frequencies
* when the device is under thermal pressure, having two big cores at relatively higher frequencies is generally more advantageous than having four big cores with lower frequencies
* the gaming profile (under Settings/Battery/Thermal profiles) remains unchanged

- October security patch
