Title: [16.04.2] POWER9 patches on top of 4.8 Status in linux package in Ubuntu: Incomplete Bug description: This is a Ubuntu 16.04.2 feature to track the inclusions of POWER9 patches on top of kernel 4.8. Ubuntu 16.04.2 is based on kernel 4.8[1], and we want to add support for POWER9 on this kernel. In order to do so, we will need to cherry- pick important patches. What are the commit ids for these patches? Once we have the first batch of commit-ids, we will get this feature mirrored to Canonical. [1] git://kernel.ubuntu.com/ubuntu/ubuntu-yakkety.git Canonical, this is a place holder at this moment. We will start to put the commits that would be required soon.
