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 [1].
