Hi Andrea,

Good to know about kexecboot.

FWIW, recently we discussed the kexec/kdump with secureboot issue
at Linux Plumbers and Greg KH suggested that it will be simpler if
we implement a new system call which does the job of loading new
kernel. Effectively that means reimplementing /sbin/kexec in kernel.
This will also mean maintaining two code bases for some time and
slowly deprecating one over a period of time.

I will probably start with something small and post proof of concept
patches for review and see how does that go. This is just heads up
on what I am planning to do.

Thanks
Vivek
