Bug found and fixed by Dave Anderson.

The reservation of space for the kexec area in
kexec_reserve_area is incorrect. It specifies the
start address and size to reserve_e820_mem when
the args should be start and end.

This patch was made against the current 3.1-testing
tip. Bug also exists in unstable.
