Patch 1 and 2 were for kernel side support. Patch 3 is kexec userland
only. I wrote this down in the patch first email (should be 0/3) but now I
see that git did not enumerate them. Sorry for that, I see that I have to
work on git skills....
The two patches tagged with [RFC] is kernel side support. The third patch
tagged with [PATCH] is also meant to be [RFC] and is the kexec userland
part against .
