commit 9a2921e5baca1d25eb8d21f21d1e90581a6d0f68 upstream. If the memory chunk found for reserving memory overshoots the memory limit imposed, do not proceed with reserving memory. Default behavior was this until commit 140777a3d8df ("powerpc/fadump: consider reserved ranges while reserving memory") changed it unwittingly.
