Hrm... this will trigger on Maple too... Should I change Maple
definition ? That would break kexec of maple from existing to newer
kernels though.

When I sent in the patch adding the code for the kernel to tell the
firmware about its capabilities on pSeries machines, I included the
function to give the capabilities to firmware but somehow forgot the
hunk that adds the call to the new function. This patch adds the
call.
