== Build & Install kernel and kexec-tools ==
Built kexec-tools with patches needed for ARM64 support, and built a 4.8.0-38
Yakkety kernel with CONFIG_KEXEC and CONFIG_KEXEC_CORE set to Y.

Title:
[Yakkety] Enable KEXEC support in ARM64 kernel
Status in linux package in Ubuntu:
In Progress
Bug description:
[Impact]
* If the kernel is not built with CONFIG_KEXEC support, kexec-tools will not
be able to live boot a new kernel over the running one.
* Our partners/customers have requested this feature.
[Test Case]
* Install a version of kexec-tools that supports ARM64
* Run the command: sudo kexec -l /boot/<kernel> --initrd=/boot/<initrd>
--append="<append string>
* You should see the message: kexec_load failed: Function not implemented
[Regression Potential]
* The proposed config changes are limited to ARM64 architecture, overall
risk of regression is low.
[Other Info]
* Please note that kexec-tools currently is not built for ARM64
* I have an SRU to enable that bugs.launchpad.net/bugs/1659618
* I am working with dannf to get kexec-tools to support ARM64 in yakkety.
